Results: Color Gamut Accuracy

AOC G2770PQU 27-Inch 144Hz Gaming Monitor Review
By

For details on our color gamut testing and volume calculations, please click here.

In the G2770PQU’s default Warm setting, the white point is almost spot-on, so there aren’t any significant hue errors in this test. Our only complaints are in the red and blue primaries. Red is a little under-saturated and slightly off-hue. Blue starts out strong in the lower saturations, while 80 and 100 percent are outside of their targets. Fortunately, blue’s luminance is lowered to compensate. The resulting errors are right at the three Delta E line. If you’re wondering about the sRGB or User (un-calibrated) modes, they look the same as the above.

Calibration tightens up the luminance chart nicely, Red and blue still show the same issues as before, though. The overall Delta E drops a little. But we’d calibrate for the improvement in white balance rather than gamut accuracy, which is decent out of the box.

Now we return to the comparison group:

A result of 2.24 Delta E represents solid color performance. The main culprits to blame for lower placing are the red and blue primaries, though. If they were closer to their targets, this number would land higher in the ranking.

Gamut Volume: Adobe RGB 1998 And sRGB

Because of the over-saturated blue primary, AOC's G2770PQU exceeds 100 percent of the sRGB gamut volume. The number would be even larger if not for the under-saturated red primary. We have no problem recommending this monitor for games, entertainment, and general computing. It is not as well-suited for color-critical applications, though.

    "At 144Hz, motion is very smooth with no obvious ghosting or artifacting. While capabilities like LightBoost are helpful at 60Hz, we’re not sure they're really needed at the higher rates."

    I completely agree. I use a benq xl2411z, and i can understand turning on the blur reduction feature at 60hz. But at 100hz and up, i just don't see the reason why. the blur reduction actually detracts from the overall experience, increases ghosting and crosstalk in particular areas of the screen. Even with modded drivers, it still doesn't seem like the best course of action.

    but light reduction at around 72hz is awesome. the only issue is the flickering, but man is the picture crisp

    400$ no thanks A 27 inch 1080P monitor should be 300$ and no more

    What do we want!?..
    - 2560x1440 144Hz ! !
    When do we want it!?
    - NOW ! !

    From what i heard when you get close to 120Hz or above you almost can't see the tearing from no-sync at all vs G-Sync, but if it has it for little to now extra charge (like im hoping will happen with free-sync) then ok.. lol

    2560x1440 144hz, <1ms response, OLED, under $500. Maybe someday... right now to do something like that would take a few more 0's on the price tag sadly, but that would look sooooo pretty at 27-30 inches. Fun to dream!

    All I ask for is a 60Hz 1080p IPS with Gsync/Freesync. Screen tearing elimination while still practical and economical. Low entry price for faster adoption by the masses.

    But no, manufacturers insist on making it exclusive to the most high end/expensive models. They want to milk the most out of this tech by keeping it elusive.

    "With speedy G-Sync-capable monitors starting to emerge, is the tech still a relevant choice?" What a stupid question to ask. Just about every monitor that comes with Gsync ARE 144Hz TN panels. Where its benefit is the least noticeable...

    Been gaming at 2560 x 1600 for over 4 years now and have moved to a Asus 32 inch 4K display with 2 GTX 780 Classifieds running it. Smooth as silk. 1080p is so 2008.

    i would be in if it was not a tn pan. unless they changed tech when I was not looking but its 6 bit color and not 8

    TN looks horrible if you're even a few degrees off center. No, thanks.

    When will they make an IPS monitor with these kind of specs?

    TN? No thank you.

    As I read this, the author repeatedly states that we will all have G-Sync monitors soon, and I keep wondering why we are all supposedly going to be using proprietary, costly, Nvidia only sync technology when AMD has put out an open source alternative that is free.

    Are changes coming? Yes. But who wins out at this point I think is going to be up to the market, and monitors that cost $35 more are going to be at a disadvantage if they both function equally or very close to equally.

    Maybe in 6 months we will be able to see both technologies side by side, and get a better idea of what each can do. But we are nowhere near being there to make this decision today.

    The larger the screen the more horrible TN becomes (unless the distance is changed accordingy - But whats the point to buy a larger screen then?)

    Got several different screens available and the TN based Asus Swift PG278Q is definatly the quickest but the picture quality price of a TN panel at that size is heavy, even at almost perfect monitor centered eyes its still borderline to wash out the colors/clarity at the edges. Compared to an Dell US UP3214Q (ips/igzo) or Dell US U3014 (ips) the TN panels is lightyears behind in picture quality (allthoo todays 4k@60hz screens have their issues with the 1.2a display port as their handeled as 2 screens).

    So if you ask me, get two screens - One for quick fps style gaming and one for desktop / slower gaming.

    So for a wishlist - An overdrive IPS panel 27-30" @ 120hz running 2560x1440(1600) and having G-sync (Ever tried an g-sync? if not - try it out, really hope Amd gets freesync to take off and Nvidia wises up and gets behind it)

    "But as long as you view the screen head-on from two or three feet away,
    you probably won’t be able to tell it apart from an IPS display."

    Sorry, can't agree there. I have a 27" Dell IPS 2560x1440, and meanwhile I
    bought my brother a 27" Samsung TN 1920x1080. Sitting directly infront of
    the Samsung, I can already see the change in colour & brightness towards
    the corners & edges of the screen, as the angle is large enough to reveal
    the effect despite not sitting off to one side. The Dell screen looks sooo
    much nicer.

    I can imagine TN panels still being reasonbly ok at 24" or below, but by 27"
    the sheer size means one doesn't have to sit off-axis to see the difference.
    With hindsight, if I'd known the effect was going to be that visible, I'd probably
    have bought him a 24" model instead, upgraded to a 27" IPS later.

    Later for my gf's PC, I bought a 24" Dell 1920x1200 IPS.

    Ian.

    27 inch monitor + 1920x1080 resolution = FAIL

    I just got this monitor (AOC G2770PQU) revied here and games like BF4 and other
    shooters which I like, haven't tried driving games, look beautiful, just turn off
    the Overdrive feature. Don't fall for the 27" at 1080p looks bad, its awsome. Single card setup can pump 100+ fps ( I got a gtx680 ftw 4 gig) and it shines at bf4,1080p.
    This monitor is a great value.
