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?

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.

• Laptop displays usually don't have scalers and can't display non-native resolutions without GPU scaling. To add other refresh rates, add the refresh rate at the native resolution. The graphics driver will automatically add the refresh rate to lower scaled resolutions.

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 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?
