iiyama PL2202W can reach 74Hz, then it shows a warning

Talk about overclocking displays at a higher refresh rate. This includes QNIX, Catleap, Overlord Tempest, SEIKI displays, certain HDTVs, and other overclockable displays.

iiyama PL2202W can reach 74Hz, then it shows a warning

EDIT: Check the other posts!

I'm using this display for some time now. For a long time I just played at a native resolution, but after I tried out playing games like CS:GO on a 4:3 resolution (and thus 75 Hz refresh rate), I was wondering if I can get the same rate on a native 1680x1050 resolution. Sadly, this screen doesn't seem to overclock well, and above ~65 Hz the screen gets severely distorted - it even shows a warning when I try 75 Hz.
Anything else I could try, or do I just enjoy the 65 Hz? :P

Yea, you can try lowering the vertical total or horizontal total till it glitches out and then rasing the refreshrate.

It's a balancing act and every monitor I've found is slightly different. Idk, go nuts still it works :P

Oh, that was it! I changed the timing standard to the second CVT option (reduced blanking), the distortion disappeared. I'm running 74 Hz now, which doesn't seem to drop frames (if I did the test correctly). At 75 Hz the screen is still showing me this warning. Even right now with 74 Hz, the OSD menu shows "H: 80.4KHz V: 73.9Hz". What's this H value?

Horizontal freq and Vertical freq.

My guess is that the message is programmed in and no matter what you do it will still pop up :(

Might be worth having a quick play around with the values but very unlikely you will get anything out of it.

Edit: oh, and the test is done correctly! well done, you have successfully overclocked a monitor! :P

72hz or 71.928hz is better than 75hz because it's an even multiple of 24 (or 23.976). Which is the standard film cadence.

Stick to 72hz, I say.

You can add both 72 and 74 in CRU.
