Asus ROG Strix XG27AQGNV review: Pulsar is the star

Standing out in the world of gaming monitors is no easy task – at a time when OLED panels are finally coming down in price, refresh rates are pushing up past the 1000Hz threshold, and people are connecting consoles as well as their PCs to their displays.

Still, when big new tech like Nvidia G-Sync Pulsar comes along, it's an opportunity for monitor-makers to push for further upgrades. It's the latest in display tech, helping to eliminate levels of motion blur you might not have even really been worried about.

If you're a competitive gamer, however, it's therefore big news – but is it enough to make you buy a whole new monitor? I used the Asus ROG Strix Pulsar XG27AQGNV for a week for this review to find out how it stacks up.

Price and Availability

The XG27AQGNV was unveiled at the very start of this year, in the halls at CES 2026, and trickled out for sale in various regions, starting roughly back in May. That means it's been around for a good few months, but it's the first Pulsar monitor I've had in for detailed testing.

It's priced at £629 here in the UK, $599 in the US, and €599,99 in the EU, which makes it objectively pretty expensive for a 27-inch, 1440p gaming monitor at this point. Whether it's worth that cash will be what I explore below, but it'll also come down to your priorities, as always when it comes to gaming hardware.

Design and Specs

You might think there's not a huge amount to talk about when it comes to the design of a 27-inch monitor, and on some level you'd be right. Asus has kept things pretty simple here, too, with a panel that has pretty even bezels on the right, left and top – but with a bit more of a chin on the bottom.

On the back of the monitor on the right-hand side, you'll find controls in the form of a control knob that you can use to navigate through the monitor's settings menus, as well as a few shortcut buttons to make things like turning it on and off, or swapping inputs, a little faster.

Then, at the back of the monitor, you'll find its I/O options: one DisplayPort 1.4 port, two HDMI 2.1 ports, and three USB-A ports for accessories and charging. That makes it relatively light on the connectivity front, to be honest – I'll always advocate for more HDMI ports where possible.

These ports can be hidden behind a removable cover that makes the back of the monitor nice and clean, with one large ornament in the form of a ROG logo that lights up with RGB (which you can control).

I don't love the aesthetics of it, but if there's one bit of tech where the back panel doesn't really matter, it's a monitor. There's more cable tidying using a gap in the stand, which has a modest footprint, making this easy to get on a smaller desk.

That brings us to the actual specs of this display. It's a 27-inch, 16:9 aspect ratio IPS panel, at 2560x1440 resolution, with an anti-glare matte finish to help make it impressively resistant to reflections. It has HDR 10 compatibility and a refresh rate cap of 360Hz.

That refresh rate is made far more impressive, though, by the inclusion of not just AMD FreeSync and Nvidia G-Sync, but also the far newer G-Sync Pulsar, which basically eliminates a huge amount of motion blur when gaming. It's really quite hard to describe, but it's a big step up compared to standard G-Sync if you're gaming at high frame rates.

Another of the most impressive specs, on paper, is the 500 nits of peak brightness – a long way beyond much of the competition. This means that if you crank this monitor to its maximum value, you'll have a bit of a beacon of a display on your hands. While this will be uncomfortable for many home gaming scenarios, it makes the monitor very adaptable to harsher conditions.

Of course, given the price tag attached, it's probably worth clarifying some of the things you don't get with the XG27AQGNV, too. It's not an OLED panel, to be clear, so you won't get quite the same inkiness in its blacks.

It's also not 4K. That 1440p resolution cap is really no issue for most sensible PC gamers, but it does mean that a console like the PS5 Pro can't output its maximum resolution to the monitor, which may well matter to you.

Performance

I've said it before, and I'll say it again – with a monitor, more than perhaps any other form of tech that I've reviewed, it's really all about the performance, and barely about the design.

So, turning the XG27AQGNV on, how's it been to actually game on? Well, in a word: smooooth. I last tried G-Sync Pulsar more than six months ago at an Nvidia event, and had limited time one-on-one with the feature. Now, using it for a whole week at my leisure, it's made quite an impact.

I don't play too many games competitively on PC, to be frank, but dipping into the likes of Counter-Strike 2 to get a feel for where the feature's impact could really be felt, the amount of clarity I was able to perceive was quite striking.

To be clear, Pulsar isn't making your game smoother – it's just making it clearer in motion, and the magic behind that is really quite something.

That's a huge plus point in favour of the XG27AQGNV, then, but it's also impressive in other areas. It's really crisp at 1440p, without text fringing that I could perceive, and while it can't quite match an OLED for blacks or vivid colour, it's one of the best IPS panels I've seen in ages on both counts.

It's also wildly bright. That 500 nits of peak brightness is hard to describe in a monitor, but it meant that when I cranked it up to its maximum value I was pretty much instantly in discomfort, and brought it back down quickly. That's something I've never encountered before, and means those with bright rooms will find a real ally in this hardware.

Of course, the way I test monitors doesn't just involve PC gaming. I also connect my MacBook Pro for my daily working routine, and my PS5 Pro for a lot of my social multiplayer gaming. In both cases, the XG27AQGNV is a very solid performer, although when a PlayStation 5 is connected it obviously can't offer the full 4K experience.

That's most likely not an issue for you, if you're a PC user first and foremost, but at a time when makers like Alienware are catering to both PC and console, it's worth bearing in mind.

Verdict

The XG27AQGNV is a niche monitor, but a highly impressive one. If you're on the lookout for an IPS panel featuring G-Sync Pulsar, it's your only real option right now (all the others are OLED). That makes its fairly steep price far more understandable, since it sits on the cutting edge.

That said, Pulsar really isn't something that many of us need, and that means plenty of people might be better off spending less on their 1440p monitor, or getting a more adaptable screen for the cash. If you care about clarity above all, though, what a legendary option this is from Asus.

Also consider

I've tested some highly impressive monitors in recent months, and one of the best has been from Dell – the Alienware AW3226Q. This is a huge, 32-inch OLED, so it's not quite the same proposition as Asus' offering, but it comes in at a similar price. Crucially, it's 4K and more reliable for switching between PC and console.

A more direct comparison could be made to the LG UltraGear OLED 27GX790B-B, which is a stunning 27-inch OLED. It lacks the Pulsar tech that Asus packs into this panel, but is a bit more impactful in terms of colour, making it something of a dealer's choice.
