Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Viewing Angles

The XG27UQ is equipped with an AHVA (Advanced Hyper Viewing Angle) panel, but in the photo above, it looks like a typical IPS part. At 45 degrees to the sides, there is a green tint and a 40% brightness reduction. Detail remains well-rendered with no apparent change in gamma. The top-down view has a blue color shift, 40% light reduction and a loss of gamma where detail is harder to discern. The XG27UQ’s viewing angles are no better or worse than any other IPS screen.

Our XG27UQ sample showed slight hotspots in the corner zones. They were just visible in a darkened room but with a few lights on, they disappeared. No color or luminance aberrations were visible in field patterns brighter than 5%.

Running an Ultra HD monitor at 144 Hz is about as demanding as it gets. Choosing the XG27UQ has a reward though; it’s the fastest 4K 144 Hz screen we’ve tested. It bests the next screen with 5ms less input lag while equaling the 7ms response time of all the 144Hz panels. Only the XG279Q with its QHD resolution is faster in this group. If you have sufficient processing power available, the XG27UQ will reward you with a superbly smooth gaming experience. We couldn’t use ELMB with Adaptive-Sync but with overdrive set to level 3 of 5, blur was a non-issue.

    1.) Does the monitor have a fan? I've read about how loud monitor fans can be, so the ideal monitor for me wouldn't have one.
    2.) Does this panel have FALD? I suspect it doesn't, given the price.
    3.) How big a difference is there between Gsync compatible and "proper" G-sync? I have a "proper" G-sync monitor with the chip, but it looks like more and more screens are just going with the "compatible" version which doesn't. I read some of the technical differences, but curious about how noticeable it is when gaming.

    I have an 1080ti and will be upgrading to a 3080 once supply stabilizes.

    So, DisplayPort 1.4 supports a maximum of 4K UHD (3840 \00d7 2160) at 60 Hz with 30 bit/px RGB color and HDR .

    You couldn't have tested 144MHz.

    Oh... I think you may have used compression.
    If you use compression I think there should be some details about that in your testing... or at least clearly state: "this is a test with compression" for each test using compression.

    I don't think saying it's expensive compared to other 27 inchers is a good con. It's a somewhat premium 4K 144hz monitor, what did you expect? Now, one con is that is has very large and ugly bezels.

    WTB 120Hz+, 4k, sub 4ms, 29-34" monitor.

    I've been stuck on 27 inchers for about a decade now. Going to another is not really an upgrade. Double this due to increase in quality of 2k.

    So its kinda pointless. We have all this wonderful new hardware cpming out that can finally run 4k really, really well, and monitor manufacturers in general seem to be just derping around instead of pumping out full lines of HBR3 displays.

    And no, I don't want it to be TV sized. Not 43", not 55" or whatever else, just an upgrade from not into 27".

    Maybe someone at Tom's Hardware could reach out to some of these manufacturers and do a write up about this hold up. Might turn out to be a good topic for an article.

    I would definitely second this. There simply aren't any 32" high refresh rate monitors out. Especially with the 3080 coming out it seems manufacturers are caught behind the times.

    Manufacturers aren't caught behind the times, they're just lazy and will continue to churn out the same, tired, old tech as they're making money. I have a simple, standard, Asus VS248HR which cost £120. It's terrible, but does what it does. I left a reasonable review on Amazon, to which Asus replied as they didn't like what I'd written.

    These companies will continue releasing rubbish, at the lower end, to ensure anything above 'standard' affords a premium. Typical, standard, every single day profit. Heck, we'd still be on 1366x768 if they had their way.

    P.s. It would be amazing if these companies also made it 100% clear if the 3.5m jack audio/heaphone out was linked to the hdmi port.

    Talks about DSC as if it helps with image lag instead of calling it out as necessary compression because DisplayPort 1.4 doesn’t natively support the bandwidth needed for 144Hz 4K
    Says you can count the number of 4K 144Hz monitors on one hand
    Doesn’t bother to list the lack of HDMI 2.1 (which has more bandwidth than DP1.4) under cons or in the part of the article I readI stopped couldn't get through this advertisement. The misinformation is frustrating. I get it, you write reviews that make products look good, but can you avoid lies and misinformation?

    How does it compare to the LG 27GN950?
    im pretty stuck atm for what i should buy, maybe its worth waiting to see if theres more options in the next few months with HDMI 2.1 support?

    Today, we’ll be looking at a less-expensive alternative that delivers everything except the FALD backlight for $800 as of writing. Meet the Asus ROG Strix XG27UQ.
    The sentence that includes the price - second paragraph.

    Yeah. Sadly, that;s how the majority of tech companies run. If they have no competition, why push hard and innovate? The only reason is so that an upstart doesn't come along and dethrone them. Just look at Intel! There are so many improvements they could easily make for consumers, but they don't because consumers are "content".
