Viewing Angles, Uniformity, Response & Lag

Viewing Angles

The Q2781PQ isn’t billed as an AHVA screen, but our photos sure make it look like one. There is only the slightest shift to blue in the horizontal plane with a 50% light falloff at most. Dark steps are still clearly visible. From the top down, color gets a bit warmer, but detail remains strong at all brightness points. This is excellent performance.

Screen Uniformity

Thanks to a little extra brightness, which we talked about in the ANSI test, the Q2781PQ just tops 11% in the black field test. It’s not bad enough to call it backlight bleed or IPS glow, but it is just above the visible point. Raising the signal level eliminates any flaws, and the 100% field measures an excellent 6.9%, which is right in line with the competition. Color uniformity comes in last among the group, but 1.64dE is still an invisible variation. The eye sees only a smooth, gray tone in the 80% field pattern.

Obviously, gaming is not a priority for the Q2781PQ but its input lag score is lower than most monitors of this genre. It’s beaten only by the BE270U which stealthily includes 75Hz and FreeSync in its feature set. The other monitors are 60Hz and devoid of adaptive-sync, so the AOC acquits itself well. You won’t be crushing your mates at the weekly LAN party, but casual players will enjoy gaming on this display thanks to a smooth-running overdrive and good image quality.

    I get why people call out the monitor makers when they call a monitor bezel-free and it's not. And I get why people who do multiple-monitor gaming would want bezel-free. But until the display actually has NO bezel, does bezel thickness matter at all? It seems that if there is any bezel, it might as well be an inch wide and help prevent backlight bleed.

    Generally, I agree. There's no functional point if there is more than zero bezel thickness. But I'll admit, a thin bezel does just look better aesthetically. If I had to choose between two monitors that were equal in every way, except one had a thinner bezel, I'd go with the thinner bezel.

    To me not having speakers is a plus since I like to use my own set of speakers... real speakers. Overall I will keep this in mind when ready to upgrade.

    I personally would rather have downward-facing inputs. It puts less stress on the connector.

    Not sure I would want 4K in a 24" monitor. That would make for some really tiny text/icons. I would only go with 4K in 27"/28" and above sizes.

    2BE_OR_NOT2BE,
    I'm not sure I agree that "downward-facing inputs" are better. With this monitor the cables can come from the back of the desk like you would a DVD player. With the downwards style you'd be forced to bend the cable more thus putting MORE stress on the connector not less.

    Personally, I prefer to have a mount that lets you hide and tie off the video cable in the rear, middle area.
