+Quality, captivating display+Great mix of 4K VA and HDR+Surprisingly affordable

Finding a display that brings together 4K support and HDR (High Dynamic Range) at an affordable price point can be something of a holy grail, but every now and then a manufacturer finds that elusive sweet spot. Take the, ahem, brilliant Philips Brilliance 328P6VUBREB, a plucky display that sports an impressive HDR 600 rating and a 3,840 x 2,160 resolution as a great example.

This monitor's very vibrant display will do your graphic design, video editing and gaming pastime more than enough justice. It's also shockingly affordable, especially when you consider this is a 31.5-inch display with 4K and HDR support. Indeed, when you compare it to certain, similarly specced screens, it delivers the same performance for under half the price.

And, we feel it is because of this mixture of great hardware and modest price point, that makes the Philips Brilliance 328P6VUBREB the first monitor many users should consider when looking to upgrade.

Reasons to buy
+Outstanding best-in-class colour accuracy+Gamma curve for editing HDR video+Incredible build quality+Non-glare panel with shading hood

Eizo displays are a familiar sight in professional photography and video production studios, due to the company's well-deserved reputation for outstanding consistent colour accuracy, with very little brightness deviation across the panel. As such they're an obvious choice for the top slot in our best 4K monitor roundup.

The 31-inch Eizo ColorEdge CG319X continues this tradition, delivering a 149 ppi DCI 4K resolution 4,096 x 2,160 panel (a slightly taller 4K standard used in digital video production) that is ideal for any sort of high-end photo and video editing work, as well as general usage and gaming.

The monitor is also equipped with a raft of high-end features, too, such as how it is  equipped with HLG (hybrid log-gamma) and the PQ (perceptual quantization) curve for displaying and editing HDR (high dynamic range) video content.

Meanwhile its wide-gamut LED backlight reproduces 98% of the DCI-P3 standard used in digital cinema and it also covers 99% of the Adobe RGB color space, too, meaning that images will always be displayed correctly.

All these features come together to produce a simply jaw-dropping image in applications across the board, which is only matched by the CG319X's asking price. At around £4,000 this serious piece of image editing hardware commands a seriously high premium, so it's really only for the professionals. However, if you can afford it and can justify the expense, then the Eizo ColorEdge CG319X is the best 4K monitor in the world.

The best budget 4K monitor

Specifications
Screen size: 28-inch
Resolution: 3840 x 2160
Refresh rate: 60Hz
Inputs: 2 x HDMI, 1 x DisplayPort
Contrast ratio: 1000:1
Reasons to buy
+28-inch, 4K display+Excellent build quality+Incredibly low price point

Not everyone has a huge amount to spend on a pixel-packed monitor, which is something that South Korean maker Samsung realises, with it 28-inch, 4K Samsung U28E590D ringing in for a fraction of some of the other monitors on the market.

Be under no illusion, though, Samsung is of course renowned for the quality of its display tech, and that is evidenced even here, with the U28E590D delivering a super-fast 1ms response time, 170-degree viewing angles, a 1000:1 contrast ratio, and rock solid connection options.

You don't get quite as many ports or quite as much size as you do on some other models, but the U28E590D cuts very few corners in hitting that fantastically low price point. Definitely worth a look for anyone shopping for a new 4K monitor on a budget.

To see how this top budget monitor stacks up against our best 4K monitor pick, be sure to scope out T3's Philips Brilliance 328P vs Samsung U28E590D comparison feature.

4. BenQ EW3280U

A superb all-round 4K display with something for everyone

Specifications
Screen size: 32 inches
Viewing angle: 178°(H)/178°(V)
Resolution: 3840x2160
Contrast ratio: 1000:1
Refresh rate: 60Hz
Response time: 5ms
Reasons to buy
+Excellent picture and HDRi+Integrated speakers and a remote+Comes with USB-C connectivity

We wouldn't say the BenQ EW3280U is the best monitor in any one particular area, but what it does do is offer something for creatives, gamers, casual users and professionals for a very reasonable price – it's perfect if you want your 4K display to wear a lot of different hats through the week.

The HDRi that is on board the BenQ EW3280U isn't technically an officially recognised HDR standard – rather it's BenQ's take on the same technology – but it does the job of keeping both light and dark areas of the screen in view. There's minimal ghosting, and the high resolution looks bright, vivid and sharp whether you're looking at a game or a movie.

And a word about the sound too: with speakers either side and on the back, you get audio that's a cut above what you might expect for something at this size and at this price. Coming from BenQ, you are of course also getting the reliability and the solid build quality that the manufacturer is known for.

best 4K monitors 2021 LG 27UL850 review

(Image credit: LG)

5. LG 27UL850

A top-notch 4K monitor with HDR and USB-C

Specifications
Size: 27-inch
Resolution: 3840 x 2160 (4K, UHD)
Aspect ratio: 16:9
Brightness: 350cd/m2
Response time: 5ms
Contrast ratio: 1000:1
Viewing angles: 178/178 degrees
Ports: HDMI 2.0, USB Type-C, DisplayPort 1.4
Features: Radeon FreeSync
Refresh rate: 60Hz
Reasons to buy
+Accurate IPS display+HDR10+USB-C and HDMI 2.0

As T3 noted in our LG 27UL850 review, this is a 4K monitor "that does a good job of just about everything", and that is why we recommend it in our best 4K monitors buying guide.

You get a 4K resolution, HDR10 support and HDMI 2.0, DisplayPort 1.4 and USB Type-C connectivity, meaning you're covered both on Windows and Mac.

The design is also very modern and minimalist, with an all-white back plate only interrupted by the recessed port array – for those who like a clean, modern look, the LG 27UL850 delivers. The only sub-optimal thing is that it doesn't have any cable routing built-in.

The refresh rate is 60Hz, so this isn't a monitor that excels at gaming, but it isn't really designed to be. The LG 27UL850 is definitely slanted more towards creative and office work, with a home office setting its natural environement.

It's price is also very firmly in the affordable ballpark, too, making it a strong all-rounder that is easy to recommend.

best 4K monitors 2021 Philips Brilliance 329P1H

Want a 4K monitor for office work? Then the Philips Brilliance 329P1H is a top choice.

6. Philips Brilliance 329P1H

A professional 4K monitor that puts work first

Specifications
Range: P Line
Size: 32-inch
Resoluion: 3840 x 2160 (4K UHD)
Panel type: IPS
Backlight type: W-LED
Aspect ratio: 16:9
Refresh rate: 60Hz
Brightness: 350 cd/m²
PPI: 140
Contrast ratio: 1000:1
Viewing angles: 178º (H)/178º (V)
Reasons to buy
+Integrated HD webcam+USB-C with 90W power+Highly adjustable stand

As we note in our full Philips Brilliance 329P1H review, this is a great 4K monitor for professionals, delivering a 32-inch Ultra HD IPS panel with integrated webcam, Windows Hello integration, and USB-C connectivity.

The screen itself is very accurate and it comes with highly adjustable stand, too, meaning it can be easily adjusted to all desks and preferences. That integrated webcam is no token afterthought, either, delivering Full HD 1080p video recording.

In terms of ports it delivers a brace of HDMI 2.0 and a Thunderbolt 1.4. Adjustability sits at 180mm of height adjustment, with the display gliding smoothly up and down, plus 90 degrees of pivot, 180 degrees of swivel and tilting from -5 to +25 degrees.

The Windows Hello integration is really nice as it allows for the automatic logging into Windows 10 using facial recognition, while the really weighty foot of the stand means it is really hard to tip or knock over the panel, too.

There's no HDR on this panel, and you don't get any gamer-focussed high refresh rates either, but if you want a 4K monitor for work, general use and streaming video content, the Philips Brilliance 329P1H is a great choice.

best 4k monitors 2021 Samsung U32R592 4K monitor

If a curved 4K monitor is on your shopping list, then the Samsung U32R592 is a great option.

7. Samsung U32R592

The best curved 4K monitor on the market for most people

Specifications
Screen size: 32 inches
Screen curvature: 1,500R
Viewing angle: 178°(H)/178°(V)
Resolution: 3940x2160
Contrast ratio: 2500:1
Refresh rate: 60Hz
Response time: 4ms
Reasons to buy
+Beautiful curved screen+Impressive response time+Strong viewing angles

If you're looking for a 4K monitor with a curved screen then the Samsung U32R592 is the best choice on the market for most people. That's because it delivers an elegant, minimal bezel screen that has a deep 1,500R curvature that really helps draw you into the panel.

It's got the tech chops, too, and is certainly not just a pretty face. A resolution of 3,940x2160 is partnered with an impressive response time of 4ms, a contrast ratio of 2500:1 and some top-rate viewing angles, too. The screen is also a just-right 32-inches in size, meaning it will fit into almost every setup.

It's not got the biggest port array, with only HDMI, mini DisplayPort and 3.5mm audio connections possible, but unless this will be an issue (and we're guessing the vast majority of people will connect via HDMI) then the Samsung U32R592 certainly will not disappoint.

best 4K monitors 2021 HP Z27

The HP Z27 looks fantastic and excels at just about any task.

8. HP Z27

A superb and sleek best 4K monitor all-rounder

Specifications
Screen size: 27-inch
Aspect ratio: 16:9
Resolution: 3,840 x 2,160
Brightness: 350 cd/m²
Response time: 8ms
Contrast ratio: 1,300:1
Color support: sRGB and BT.709
Reasons to buy
+Looks the part+Excellent colour reproduction

The HP Z27 not only looks fantastic – from the screen to the stand – it also comes with a USB-C port so you can charge your laptop (or your phone) while you're working. It's well worth a place in our round-up of best 4K monitors, particularly if you're looking for something sleek for the office.

With a resolution of 3,840 x 2,160 pixels, you've got plenty of room for those spreadsheets and webpages, but at a size that doesn't necessarily overwhelm a small or medium-sized desk. Obviously something bigger will be more immersive, but not everyone needs something huge set up in the attic or study.

Another point worth mentioning is the excellent colour accuracy on this model, making it one of the top choices out there for professionals working with images and video on a regular basis. Really though, whatever you're using it for, the HP Z27 is a winner.

best 4K monitors 2021 Samsung M70A Smart Monitor

Want a 4K monitor for both work and play? Then check out the Samsung M70A Smart Monitor.

(Image credit: Samsung)

9. Samsung M70A Smart Monitor

A 4K monitor for both work and play

Specifications
Size: 32-inch
Screen type: LED
Resolution: 4K Ultra HD
HDR: HDR10
Refresh rate: 60Hz
Features: Smart TV, Bixby AI
Reasons to buy
+Smart TV apps and features+Wireless DeX and Office 365 support+Competitively priced

The Samsung M70A Smart Monitor does what many of the panels in this best 4K monitors buying guide don't – it offers Smart TV functionality built in. That means that the screen can act as both a monitor and Ultra HD TV in one.

The Smart TV functionality comes courtesy of Tizen, which through its Tizen 5.5 Hub allows services like BBC iPlayer, Netflix, Disney+, Amazon Prime Video and NOW TV to be accessed directly.

There's built in WiFi, too, so you can hook the monitor up wirelessly to your home or office network, and there's plenty of ports for connecting it to a computer or other device, including two HDMI 2.0 ports a USB Type-C port and two USB 2.0 ports.

In terms of the actual screen itself, it delivers a 4K Ultra HD 3840 x 2160p resolution along with HDR10 compatibility, which means pin sharp visuals. The monitor has a 60Hz refresh rate. Audio is handled by two 10W speakers that use Dolby Digital Plus.

In terms of extra fixtures, the M70A comes with Samsung DeX, TapView and Bixby built in, with the latter Samsung's smart AI assistant.

Overall, this is a strong 4K monitor for those who also want their panel to act as a TV. It's not the best choice for gamers, as the 60Hz refresh rate isn't ideal, but for those who want to kit out their home office with a good panel for working and enjoying the odd show after work or a movie or two at the weekend, it's a great choice.

best 4k monitors 2021 Acer Predator X27

For mature professionals who love to game in their spare time, then the Acer Predator X27 is a superb choice.

10. Acer Predator X27

A brilliant 4K monitor for professionals who like to game

Specifications
Screen size: 27 inches
Resolution: 3,840 x 2,160
Aspect ratio: 16:9
Response time: 4ms
Brightness: 1,000 cd/m2 (peak)
Contrast ratio: 1,000:1
Reasons to buy
+HDR-level brightness+Low 4ms response time+Stand-out design

Sitting wonderfully in the gap between out and out gaming monitor and all-round premium 4K monitor powerhouse, the Acer Predator X27 delivers a fantastic system for both work and play.

Not only do you get a Ultra HD 4K screen here, but you get one that boasts a proper HDR peak brightness of 1,000 cd/m2, a response time of 4ms, and a refresh rate of 144Hz. That is an astounding combination of top monitor tech and it makes watching 4K HDR movies and playing today's best games a no-compromise pleasure.

The design is clean and modern, too, meaning that the monitor fits easily into an office, study or gaming room setup. Naturally, to get the most out of such a monitor then you will need a powerful PC or games console, but if that is you and you can stretch to the X27's undoubtedly premium price point, then it comes very highly recommended.

11. Acer ConceptD CP7271K

Best for content creators who game in their spare time

Specifications
Screen size: 27 inch
Resolution: 3840 x 2160 UHD
Aspect ratio : 16:9
Response time: 4ms
Contrast ratio: 1,000:1
Reasons to buy
+Incredibly vivid colours+1,000 nits peak brightness+4K UHD resolution
Reasons to avoid
-No USB-C connectivity-You can’t rotate the screen-The in-built speakers sound hollow

For those who spend the day creating content and spend the night playing videogames, the Acer ConceptD CP7271K 4K monitor will satisfy every need. 

With high-end specs to match the eye-watering price, the Acer ConceptD CP7271K boasts a 144Hz refresh rate, IPS display, 1,000 nits of brightness, wide colour gamut and Nvidia G-Sync Ultimate. The design favours a more aesthetic approach than other monitors on this list, with the base having a wooden effect paired with a matte-silver stand. You can decide for yourself if it’s your style or not. 

In use, it proved to have some incredibly vivid, accurate colours while the 4K resolution gave it absolute clarity. It seemed to be better for content creation rather than video games, despite having some serious gaming features, but for those who like to do both, its a good choice. 

best 4K monitor 2021 Philips Momentum 436M6VBPAB

With 43 inches of real estate to play with, the Philips Momentum has space to spare.

12. Philips Momentum 436M6VBPAB

A do-it-all 4K monitor of simply epic proportions

Specifications
Screen size: 43-inch

Panel technology: MVA
Inputs: DisplayPort 1.4 x 1, mini DisplayPort 1.4 x 1, HDMI 2.0 x 1, USB-C (DP Alt mode), USB 3.0 x 2 (w w/fast charging)
Reasons to buy
+Huge 43-inch 4K panel+DisplayHDR 1000 tech+Ambiglow lighting+Low input lag of 4 ms

There's so much to love about the Philips Momentum 436M6VBPAB that it is difficult to know where to start. It's a simply massive panel, measuring in at a TV-sized 43 inches, which means you're never strapped for space. Thanks to its 4K, DisplayHDR 1000 panel technology, too, the picture quality it delivers is also impressive, with up to 1000 nits of peak brightness accessible.

Elsewhere, the 3,840 x 2,160 resolution screen also comes with a gamer-focused 4 ms response time and Adaptive-Sync technology, which means input lag is moot and high-speed gaming sessions a super smooth, click-and-hope free experience. Naturally, thanks to the screen's Quantum Dot colour tech, too, images and videos are presented naturally and with rich, vivid colours.

Lastly, a smorgasbord of connection options, including DisplayPort and miniDisplayPort, HDMI and USB-C mean that hooking the monitor up is never an issue either, and its cost, coming in just over the £500 mark makes it very approachable to most shoppers as well.

The picture quality isn't absolutely the best-in-class in this guide, however, just like everything else about it, it is good and complements a strong all-round 4K monitor package that excels in delivering huge screen space.

best 4K monitors 2021 BenQ EW2780U

A good value 4K monitor from BenQ that suits entertainment and general use.

(Image credit: BenQ)

13. BenQ 27-inch EW2780U

One of the best affordable 4K monitors on the market

Specifications
Screen size: 27-inch
Resolution: 3,840 x 2,160
Refresh rate: 60Hz
Panel technology: IPS
Inputs: HDMI x 2, DisplayPort x 1
Reasons to buy
+Intelligent take on HDR+Bright, vibrant 4K performance

The BenQ EW2780U comes with a special proprietary technology branded HDRi – the "i" is for "intelligent", we think – that apparently uses both the content on screen and the ambient lighting to give you a better HDR experience, with no loss of detail in either the darkest or lightest parts of the picture.

In our experience it's better than standard HDR in some cases but not in others, but there's not a huge amount in it (and you can at least turn it off if you don't like it). There are actually two HDRi modes, one for games and one for entertainment, so that's plenty of room to experiment.

Otherwise this is another top quality monitor from BenQ, as you would expect from a manufacturer that's been in the business for years now. You'll have no problems at all with the build quality, initial setup and on-screen controls, and that's before you get to the spec of the monitor.

As well as 27 inches of space, you get a 4K resolution and a response time of 5ms. A good number of ports are included for a monitor this size as well, and the price (typically well under £500) is definitely on the reasonable side.

Having fired up the BenQ EW2780U for a variety of movies as well as some everyday computer work, we can confirm it's a sharp, bright monitor that shows off content very well – whether that's a 4K stream from Netflix or an Excel spreadsheet – and definitely worth a place on your best 4K monitor shortlist.

You're looking at a pixel resolution of 3,840 x 2,160, a screen size of 27 inches and a refresh rate of 60Hz with the LG 27UK650-W, and that puts it firmly in the all-purpose 4K monitor category – it's a screen that can be used for just about anything you can use a display for, and it's going to pass any test you give it with flying colours.

Up close and in use the LG 27UK650-W panel is bright and vibrant, with superb colour reproduction and clarity. We'd be happy using this monitor for gaming, or for office work, or both, and there's support here for AMD Freesync variable refresh rate technology too, which is going to appeal to gamers.

In terms of looks, the monitor manages to be sleek and unfussy, and it's the sort of display design that can fit in just about everywhere. No matter what your desk setup or what you plan to do with it, the LG 27UK650-W is a 4K monitor that'll impress you.

And, do you know who else it impressed? Not only the entire T3 Awards 2020 judging panel, with the LG27UK650-W winning the highly desirable Best 4K Monitor award. That shows you just what a quality monitor it really is.

best 4K monitors 2021 Dell UltraSharp U2718Q

Brightness: 350 cd/m²
Response time: 5ms
Contrast ratio: 1,300:1
Color support: 1.07 billion
Reasons to buy
+Attractive, rotating design+Impressive colours and contrast

There's no doubt that Dell knows what it's doing when it comes to electronics, and the UltraSharp U2718Q confirms that: this understated, high-quality 4K monitor impresses in just about every category, though it's a bit more suited to the demands of the professional than the gamer.

It certainly looks the part – check out those ultra-thin bezels and the minimal aesthetic of the stand. Colour accuracy and port selection is good too, with two HDMI slots, a DisplayPort socket and a mini DisplayPort socket, and two USB 3.0 ports as well. Despite all this potential cabling, everything is kept neat and tidy around the back.

The best part of the Dell UltraSharp U2718Q is the picture that you get, which is crisp and clear and vivid – it even makes spreadsheet work enjoyable. The screen can rotate around 90 degrees at an angle as well, if you need a more unconventional monitor setup.

best 4K monitors 2021 Samsung 32" High Resolution Space Monitor 4K

Samsung's 4K space monitor is a unique proposition and, quite comfortably, one of the best 4K monitors on the market.

16. Samsung 32-inch High Resolution Space Monitor

The best 4K monitor for space-saving minimalism

Specifications
Screen size: 32-inch
Resolution: 3,840 x 2,160
Refresh rate: 60Hz
Panel technology: VA
Inputs: Mini DisplayPort x 1, HDMI x 1
Reasons to buy
+Clever clamp stand+3-sided bezeless display+Very adjustable+Strong cable management

If you're looking for a quality 4K panel that also specialises in maximising desk space then this cleverly engineered Space Monitor from Samsung should be right at the top of your shopping list.

The magic-maker is the monitor's clamp system, which locks the monitor's flat stand to the rear of a desk very firmly, with a simply twist to lock system fixing it firmly in place. The monitor, which is completely bezeless on three sides, simply then slots into the stand, where it can then be secured with a few screws. A snap-on backplate then hides this.

The Space Monitor can then sit flush to the back of the desk, allowing it sit right up against walls, as even the few cables that extend down from its ports can be cleverly routed through cable channels carved into the back of the stand. The stand is hinged at the base, too, and allows it to be brought forward and downward at any angle (zero-level HAS) until the base of the monitor sits flush with the table.

Panel-wise, Samsung delivers a 3,840 x 2,160 resolution monitor with a 16:9 aspect ratio, typical brightness of 250 cd/m2 and a 2500:1 contrast ratio. Response time sits at 4ms (GTG), refresh rate at 60 Hz, and horizontal and vertical viewing angles at  178°. In other words, a quality and versatile 4K screen.

Are there other monitors in available that offer similar viewing experiences? Absolutely. But there aren't any that deliver such a stunning, space-saving design. One of 2021's strongest 4K monitor choices.

+Great colour accuracy+10-bit IPS panel with 16-bit look-up table

Dell's latest high-end 31.5-inch 4K display packs in a lot of professional-grade features for superb colour accuracy. It has a specification that almost rivals Eizo's monster CG318-4K (see above), as it hits 99% Adobe RGB coverage and 87% DCI-P3, delivering great picture quality.

While it costs a lot less than Eizo's offering, it's still a pricey prospect, though, which is to be expected of a large high-end 4K display in 2021. Nevertheless, if you want a premium 4K monitor but can't stretch to the Eizo, it's definitely worth a look.

18. Acer Predator XB281HK

A well-priced, gamer-focussed 4K display with Nvidia G-Sync

Specifications
Screen size: 28-inch
Resolution: 3840 x 2160
Refresh rate: 60Hz
Panel technology: TN
Inputs: 1 x DisplayPort
USB: 4 x USB 3.0
Reasons to buy
+G-Sync up to 60Hz+1ms response time+Strong connection options

Like the Asus ROG Swift PG27AQ, Acer's Predator XB281HK is a 4K monitor with G-Sync technology ensuring no tearing or stuttering in games up to 60Hz.

It uses a TN panel, which can't offer the same wide viewing angles of IPS displays, but it makes this monitor a lot more affordable than the Asus ROG Swift. Indeed, the XB281HK is nicely priced for a general 4K display, so the inclusion of G-Sync is an impressive addition.

Being based off TN technology also means a lower 1ms response time, which is essential for the most serious of gamers. A worthy entrant on our best 4K monitors list.

Digital designers will be in hardware heaven with the BenQ PD3200U thanks to this 4K monitor being calibrated for super colour accuracy, contrast and crisp image quality. The screen is also a bit of a whopper at 32 inches, leaving users plenty of real estate to play with.

As the screen is really designed for professionals, it also comes with a darkroom, CAD/CAM, and animation mode, keyboard video mouse and embedded SD/MMC card reader with support for SD/SDHC/SDXC/MMC.

It certainly costs a pretty penny, and isn't much of a looker, but when its base functionality and features are so good, that doesn't matter so much if you're in the market for a top 4K monitor at the moment.

USB: 4 x USB 3.0
Reasons to buy
+Very affordable 4K display+Picture-in-picture mode

Since 4K is still quite a new technology, most of the displays in this list are pricier than a lot of non-4K displays – but Iiyama's 28-inch B2888UHSU is much more reasonable.

It uses a TN panel with a 1ms response time, and although the viewing angles aren't quite as wide as you'll find with an IPS display, there are plenty of small extras that make the B2888UHSU a really good buy.

It has a copious number of video inputs for example, a fully adjustable stand, and a picture-in-picture mode, as seen with other larger displays, so you can use two devices simultaneously with this monitor.

The perfect monitor for the modern workstation

Specifications
Screen Size: 27-inch
Resolution: 2560 x 1440
Refresh Rate: 60Hz
Panel Technology: IPS
Inputs: DisplayPort (HDCP 1.3), HDMI (HDCP 1.4), USB-C (70W
Reasons to buy
+Seamless daisy-chaining via USB-C+Ergonomic +Homeworking specialist

First, the EIZO EV2795-BK FlexScan isn’t a 4K monitor, but after some consideration, we think it deserves a spot with the best 4K monitors. Why? It's one of the most robust screens currently available on the market, and we want you to consider it before you jump headfirst into a 4K purchase you may just not need!

What this monitor offers instead of 4K is a multi-device docking juggernaut: a 70-watt power supply keeps your laptop juiced up via USB-C, seamlessly daisy-chaining multiple monitors to transform your home setup. The EIZO EV2795-BK isn't short of ports, either: three USB-A ports are more than enough for the accessories you'll need to connect, and Eizo’s ergonomic stand is a pleasure to adjust, tilt, and pivot to accommodate a good mix of viewing angles.

The 2560 x 1440 resolution screen is perfect for the home office, which is the 27-inch EV2795-BK’s natural habitat, delivering highly accurate color reproduction, versatility, and bags of tricks for both the average home office user and those who work with graphics and video. The EIZO FlexScan EV2795-BK’s sRGB mode impressively levels the color field, removing the need to compress the color gamut that can warp colors and display them incorrectly. 

It's expensive, sure, but the accelerated shift towards home working makes the EIZO EV2795-BK FlexScan worth every single dime, not least because it has merit as a machine in its own right, but because it delivers way beyond a desk monitor. If you're in the market for a new home office monitor, then please look no further than the EIZO EV2795-BK FlexScan.

A superb choice for lightweight laptop users

Resolution: 3,840 x 2,160
Refresh rate: 24-86Hz
Panel technology: IPS
Connectivity: HDMI, DisplayPort, USB 3.2 Gen 1 Upstream/65W power, 2 x USB 2.0 downstream, 2 x USB 3.2 Gen 1 downstream
Reasons to buy
+USB 3 hub with power delivery+Excellent connection options+Good angles and colour reproduction

If you have a slim, modern laptop you probably don’t have many ports to connect things to – and that means this Dell 4K monitor could be the perfect solution. It has a built in USB 3.2 Gen 1 hub with 65W power delivery, 2 downstream USB 3 ports and 2 USB 2 ones, enabling you to connect your laptop via a single cable and access multiple accessories without lots of hassle or an additional hub. It has an always on mode so you can continue to charge connected devices even when the display is off.

The IPS panel has excellent viewing angles and the monitor can be tilted, swivelled and height-adjusted by a maximum of 5.9 inches (150mm), and it has Dell’s ComfortView to reduce blue light. If you’re feeling flush the ultra-thin bezel lends itself well to a twin-display setup, and while it doesn’t include its own speakers it’s designed alongside an optional soundbar, the Dell Slim Soundbar. 

How to choose the best 4K monitor for you

It's really important to do your research when choosing the best 4K monitor for you. From refresh rates to adaptive-sync capabilities, be sure you know exactly what these features are and whether they'll influence your decision before you make it. A little research goes a long way when investing in new tech.

To this end, below our list of top 4K monitors we've included some advice that should help you narrow down and determine what UHD screens you should be looking for, and ensure you land a panel that you'll be impressed with.

The natural successor to 1080p screens and televisions is of course 4K, which is also marketed as Ultra HD (UHD). There are four times as many pixels, which means four times as much detail.

Movies look good at 1080p, but in 4K the picture really gets to that breathtaking level – and as long as your PC can handle the processing demands, playing games on a 4K display is an amazing experience, too.

When choosing a monitor, you need to take into consideration factors such as colour gamut and response time, the latter being a reflection on how good the panel will be for gaming (the faster the better). 

You also – naturally – need to work out which panel size you need. 27-inch displays are the sweet spot for us, although you can get some cracking deals on larger displays, too. With all that in mind, here's our roundup of the best 4K monitors currently on the market in 2021.

Who makes the best 4K monitors?
