Monitor Tests Forum

Hi, all! I have a problem about my X-star 2710 (Same panel as Qnix 2710).

My monitor is doing 120hz without artifacts. The problem is that when I increase my refresh rate via CRU, top right side of monitor is becoming darker in (128-0-0) half color values than left side of monitor. Moreover, slight dark columns appear at right top side. Strange thing is top green, red or blue colors (255-0-0) are perfect and not affected with this problem. It can be seen at 90hz but so minimal. At 60hz, there is no problem at all.

Green colors are more vulnerable than blue or red. So, I am sharing pics of half green (128-0-0).

All there are LCD Reduced. It looks like LCD Standard has no impact with this issue. What is my problem exactly and how can I solve it?

The problem is your monitor can't handle higher refresh rates without uniformity problems. That darkening is a common artifact when overclocking the QNIX/X-Star monitors, although some units are better than others. Reducing the horizontal total to 2652 might help a little, but if it's happening at 90 Hz, then there's no way to avoid it at higher refresh rates. There's nothing else you can do except try another unit and hope that one is better.
