Custom Resolution Utility (CRU)

[XAGMNINETY]

Hi everyone, back again with a quick question concerning my LG OLED.

So this TV officially natively supports 50, 60, 100 and 120 Hz (along with 24 and 30, obviously) as potential native refresh rates. Obviously, 60 and 120 both work fine (at 1440p, haven't tested 4K yet as I have a 2080 Ti and run it through an AVR, but I assume the same).

Although I have to create CRU resolution values for the PAL refreshes, both 50 and 100 Hz also work perfectly, with seamless visual smoothness and exactly like you would expect an official refresh rate to work. Good so far.

However, my CRU values of 75 and 90 Hz, unsupported refresh rates, do not work as intended. Both exhibit a micro-stuttering of sorts that's clearly visible both at the desktop and in game. In theory, these native refresh rates are great for games like Valheim and Horizon: Zero Dawn that won't run at 120 Hz on any hardware but could benefit from a nice intermediary frame rate between 60 and 120. Notable for mention, of course, is that on my Dell 32" at my workstation PC and on my gaming laptop, these CRU refresh rates work just fine. Those, though, are dedicated PC monitors and are not televisions.

Am I missing something? Are my timing inputs incorrect, or is there some specific setting to get exactly 75 or 90 Hz refresh rates? Keep in mind that I'm just putting 75 and 90 as flat numbers in the refresh rate slot of CRU, and I understand that most supported refresh rates have decimals. Or is it just a TV incompatibility? No worries if that's the case, but I'd like a working 75 or 90 on my OLED.

Thanks in advance.
