Did you try the suggestions in the link?

Thank you for your excellent app and for your time you devote in answering every question in this topic
I have a LG 29UM68 UWFHD 21:9 75Hz Freesync monitor paired with a 5700XT Sapphire pulse over DP and I'm having the memory issue you described in the OP ... what would be your suggestion to alleviate the problem?

Did you try changing 2560x1080 @ 75 Hz to "CVT-RB standard" timing?

Recently I have upgraded my rig, and after upgrading, my monitor resolution is stuck at 1024x768. I am using Dell E1912H which Native Resolution 1366 x 768 at 60 Hz, VGA Interfaces. Besides it's showing as non generic PnP monitor. I have windows 10 with GTX 1660 super. I used HDMI converter to connect it to the GPU. My graphics driver is up to date. So, please let me know How can I make it to the native resolution of 1366 x 768 rather than stuck at 1024x768 using the app. Thank you.

Did you try adding 1366x768 @ 60 Hz as a detailed resolution?

thank you for your reply

This is the screen of CRU after a "reset-all"


and changing the 2560x1080 detailed resolution from this


to this did not solve my problem


I even added another detailed resolution 2560x1080 @ 75 Hz CVT-RB, again with no success

what should be my next step?

Hello all,

I've been looking for a step by step guide to help me to fix an issue I have on new computers.

I'm using to access remotely to my Windows 10 computer a HP software called ZCentral Remote Boost (aka RGS) - My new computer come with Geforce GTX video card. When I unplug the screen and I try to access my computer I only get a Black Screen because Win10 seem to disable it.

I've read (but without any details of how to do it) that there could be a way for CRU to create a EDID file/config and force it to Spoof a plugged monitor.

Any chance I could find some help here to achieve this?

Regards,

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.

The TV probably skips frames with non-CTA modes. CTA-861 only includes 24, 25, 30, 48, 50, 60, 100, 120.

Cool, this is what I figured. Monitors generally don't need CTA modes of refresh, right? That's why I can get 90 Hz smooth motion, no issues, on my laptop and Dell Desktop monitor?

Mate, you have a PayPal link? Would love to throw you a few bucks. Thanks again.

Hi. I have Sony X900E 4K TV and just wanted to know: can I use CRU to make it work at 1080p@120hz with PS5 console? This TV doesn't support 120hz natively, only through forced resolutions, which PS5 isn't capable of. So, can I permanently rewrite TV's EDID, so that the console recognize TV as 120hz capable or it's impossible?

Yes, In fact I tried that solution before know CRU but any of these settings didn't work on my laptop. I still don't understand why Exact Reduced seems to work.

Right now my screen flickers occasionally instead of constantly. That's great because I had almost decided to throw the laptop hahah

The problem seems to be solvable adjusting the configuration of CRU as AMD can't do that correctly. But I don't know how to improve it.

Thanks you

You edited the 60 Hz detailed resolution. Edit the 75 Hz detailed resolution.

CRU does not emulate monitors. You might need a dummy plug.
