Aorus KD25F 240 Hz Gaming Monitor Review: Breaking Our Benchmark Records

Editor's Choice

Viewing Angles, Uniformity, Response and Lag

Viewing Angles

The KD25F exhibited the usual TN weakness when it came to off-axis image quality. From the sides, there was a significant color shift to green and red, and brightness was cut in half. However, detail remained strong with all steps clearly visible. From the top, we could barely see a difference between the darkest and lightest tones, and the color became decidedly purple. This monitor is always best used from a head-on position.

Screen Uniformity

Screen hotspots are always a bummer when gaming in dark environments, but luckily the KD25 exhibited none of that behavior. With a super-low score of just 6.15% you won’t see any glow or bleed, even when the screen is completely black.

Pixel Response and Input Lag

Our final test results demonstrate why one pays $500 for a 25-inch monitor. We thought with a 23ms total lag score that the KD25F was the fastest monitor we’ve tested, but that honor still belongs to the Alienware AW2518F. What is more impressive, and more important, though, is the response score, a record low for our lab. While one or two milliseconds may not seem significant, the KD25F is the smoothest monitor we’ve ever seen. Its overdrive works incredibly well, and that contributes to absolutely perfect motion resolution at all framerates. Of course, FHD means you’ll top 200 fps with a well-equipped gaming rig.

    The Alienware one I bought seemed defective, as OD error was atrocious at 240hz and wasn't adjustable regardless of OD setting. Setting the monitor back to 144hz fixed all the problems. I hope the Aorus isn't the same.

    Lipstick on a pig somewhat, as we already have a vastly superior and responsive technology, OLED. Would kill for a 25" 240hz OLED monitor instead, with even faster response times standard.

    I have the Alienware AW2518HF. It is flawless as far as freesync is concerned. It is also about 150 dollars less.
    I would get the Alienware.

    There's an updated version of the AOC AG251FZ, the AG251FZ2. I know because I just owned it for a month before returning it for reasons unrelated to its performance. Why didn't you compare this monitor to that one instead? That would have been much more useful.

    23ms total lag? Don't you mean 2.3ms?

    I just got this monitor, I love it so far but I have a few questions, mainly, does Aim Assist need to be on for the fastest input speed? I've noticed with Aim Assist it dims the screen considerably. I was just curious if the config given for the best color was with it on or off.

    I think Aim Assist is the Black Frame Insertion feature. You don't need it on and it probably slows down input speed a little bit.
