I just got this monitor yesterday. I can notice a little bit of backlight bleed/clouding (don't actually know the difference between those two) on the left side of the screen, but it's nothing major. Overall I think it's a good monitor. However, if I set the monitor at 144Hz I get like strange white very thin horizontal lines. It's not really too bad I guess, but it's still annoying. This is especially noticeable on a gray solid background color on the top right corner. Have you ever seen this yourself?
At 120Hz I can't notice this. Also if I set the monitor to a custom refresh rate of 130Hz using the NVIDIA Control Panel the problem also disappears. I think it's still fine if I can run the monitor at 130Hz instead of 144Hz. 14Hz less is not a big difference in this case. Is it safe to use this custom refresh rate of 130Hz in the long run?

I whish I could show you a picture of the artifact. It looks something like this:
[+] solid color
[-] thin horizontal white lines

At 120Hz I can't n

No, I took a very detailed look at this issue. But it sounds as the Iiyama can differ within each unit? That would be strange and the first time I hear from this. Maybe they also have built in a new revision or another panel? Hmm

Don't have made any experiences in a "long run" when "underclock" the monitor. But I THINK this shouldn't damage the monitor


I know pretty exactly what you mean by these scanlines, many monitors suffer from this issue while in some monitors it is much more visible compared to others. If its something you cant deal with I personally would exchange this unit and try another one or get the Viewsonic XG2401 for example

I'm suspicious as to whetter this actually works. Ever tried this?
Yes, I have tried different solutions like pencil rubber or run some specific test pattern for stuck pixels, but it does not help in my case :/

I think scanlines in current 144 Hz Full HD monitors will differ within each individual unit a bit. The XG2401 for example has had only a bit of scanlines in the top right of the screen, a bit weird
