AOC AGON AG271QX Adaptive-Sync Gaming Monitor Review

Rating: 8.0.

The market for monitors specifically aimed at gaming seems to be thriving. The AG271QX is the first one we have seen from AOC’s new AGON range, specifically designed for the gamer. It’s a 27in unit with plenty of bells and whistles to attract the intended user.

The 350cd/m2 brightness and 1000:1 contrast are pretty standard, and the 1ms response rate is almost a prerequisite for a gamer screen. But this 27in unit boasts a 2,560 x 1,440 resolution, 144Hz top refresh, Adaptive Sync technology, gaming presets, and a handy wired keypad that makes the OSD buttons more readily accessible.


Like most gaming-oriented displays, the AG271QX is based on a TN panel. Although this technology has trouble competing with IPS for image quality, it beats the latter hands down for pixel response, which is arguably more important for gamers anyway, since a difference in screen lag can mean a loss instead of a win.

There’s a good range of input ports available, including audio and a USB 3.0 hub. There are even 3W speakers built in. The orientation and height are fully adjustable, and plenty of adjustment is available via the OSD.

Costing just shy of £400, this screen is somewhere in the middle of the price range for 27in displays. Let’s find out if its abilities are similarly middling, or help it stick out from the crowd.

Zotac has launched the world's smallest GTX 1080 Ti - just how good is it?

    Is it any good for computer graphics? Currently i have Iiyama X2380HS and its too small. I want to change it but it looks like there is nothing on market that will fit me. Im looking for 27+ 1440p 144hz IPS and i don’t want to sell my kids for it.

  • Joe Thornton

    Ok so, you say it’s not cheap. Can you suggest any other monitors that are 1440p and 144hz and cost less? I haven’t been able to find any, in which case, it is good value. Though sure, you can get a 27″ 1080p 60hz monitor for much less but it’s hardly comparable.

    You can get the Asus MG278Q for $399.

    This panel is TN

  • Joe Thornton

    Based off of UK pricing like the article, the MG278Q is £449 on Overclockers or £419 on Amazon so it’s not cheaper.

    If I ever see a “red & black” themed “gamer” item or a “red & black” themed computer build again, I’m going to vomit. Even if you actually like that color scheme, you think people would abstain just based on how played out it is…it has become a trope of the “gaming” world and it needs to be stopped

  • Christopher Lennon

    why is computer hardware cost twice as much in Britain than it does in America?

  • Joe Thornton

    American prices don’t always include tax like ours do, plus we add import tax on products.

    “it beats the latter hands down for pixel response, which is arguably more important for gamers anyway, since a difference in screen lag can mean a loss instead of a win”

    You know that gamer doesn’t always mean people playing competitive shooters right…?

    Can we get some proof that Nvidia now supports Adaptive-Sync as I can’t find anything on the internet to support this statement?

  • Sai Krishna Vajjala

    No. It does not. Only thing I read recently is Nvidia Fast Sync – which is a completely different thing – supported on all monitors I think. Other than that, Nvidia has not yet officially made a statement about supporting Adaptive Sync standard of VESA

  • Vivekanand Athanikar

    Can anyone confirm that this supports VESA mount?
