First time using CRU. My monitor's native resolution is 3440 x 1440 @ 144 Hz. I want to use 1080 x 1080 to test something in a game. My CRU is as such:
![[Image: CRU.jpg]](https://i.postimg.cc/k47sNJJ0/CRU.jpg)
Even after using restart.exe, or restarting my computer, there is no 1080 x 1080 resolution listed neither in regular resolution drop-down nor in "List all modes" on Windows 10. I also added the crazy standard resolution you see on the right column (1536p) to test if it would show up, but it doesn't either. What's wrong?
Hello!
I want to boost the Hz of my monitor, iv used CRU and it worked on 1920x1080. However, i play with lower resolutions on my computer, and when i try any lower resolution that 1920x1080, my screen goes black and i cant do anything. This black screen o nly hapends when im overclocking resolutions lower than 1920x1080. Is there anyway to Overclock the Hz of my monitor using a lower res? Im on a labtop by the way.

It seems like with Exact Timing my VRAM Clock is still locked at 2100Mhz even with one screen On... with Automatic (PC) timing the VRAM Clock drop to some Mhz with one screen On).
On the right side, the 2560x1440 screen set on Manual with horizontal total set to 3600 and pixel clock that i have changed to 777.61 Mhz to match the 3440x1440.
Note that i've tested with automatic (PC) timing on the 3440x1440, this give a pixel clock of 799.90 Mhz, I tested to copy this setting to the 2560x1440 screen and the results are the same, black screen and nothing.
There's no way to make this work then. The monitors have to be synchronized to be able to change the memory clock. Normally this is done during the blanking periods to avoid garbling the screen contents, but if you have two monitors that aren't synchronized, then this is impossible without affecting one of the screens. You would be better off having two monitors with the same resolution.

I factory reset my TV and that fixed that problem. Reinstalling windows fixed the PC issues. The only thing still is, the metadata of the videos I record with Shadowplay or Action, say limited color range. I'm not sure. It looks like full RGB to me. In game, pressing the green button on my TV remote 5 times quickly, even tells me it's full RGB. All my settings are correct. Even Nvidia Tech Support says it's got to be a bug. Incorrect Metadata? I'm not sure
That sounds like a ShadowPlay bug.

Windows will list it as 68 Hz, but the actual refresh rate is not rounded.

Ok thanks for your help, at least we have tried !
New user. Trying to install and run but when I click on cru.exe it simply vanishes from the folder and I don't see the program on my screen. I don't see it under task manager, I can't switch to it using alt-tab. If I try to unzip the file again to get a new cru.exe there an error message that an unexpected error is keeping me from copying the file.
I'm totally lost how to access this program on my Windows 10 laptop with Intel and Nvidia graphics cards.
What the heck am I doing wrong?
Quick note: tried it on my desktop computer and it runs fine.
Curiouser and curiouser...

Sounds like a bad antivirus program is deleting the file without telling you. What antivirus are you using?
