My tv is standard definition so I ended up getting a double image (see attached picture) and cannot use 640x480 progressive (if that’s what you meant). Can I still use this method on my tv with different values? I’m guessing I’d need to keep it within the 15khz range?

Thanks so much for taking a look into my issue I really appreciate it.

What about 640x480i with 262 lines total? The problem is 480i is meant to be double-clocked (and 720 wide), so it's normally 1440x480i, which would cause the same aspect ratio issues. The only other workaround I can think of is to use the working 2560x240 and enable GPU scaling so 320x240 is scaled up to 2560x240.

Hi, i need really help beaucase i am going MAD

My monitor ITEK 40" ultrawide 3440 * 1440 144hz will show resolution i can't delete.
I have to delete 3840*2160 60hz beaucause is not in the correct format... and NVIDIA Nis won't work correctly.

I found a way via CRU deleting "default extension block", in this way incorrect resolution won't be showed in windows or nvidia panel. BUT, that's the problem, When i try to set manual resolution i CAN set only 3440 * 1440 at 110hz refresh, no way to get 144hz, why???
That's my settings
Thx

You need to add it in a DisplayID extension block.

Hey, I hadn't used CRU for like a year, and now I've been using it again, but when I use restart64.exe after importing settings, it sometimes doesn't recover from the black screen, and I have to restart my PC (CRU settings persist)

What might be causing this issue? I never had this issue back when I first starting the program like a year ago

I don't understand what you're saying. Describe what you are doing and what is happening.

This would be a driver bug. The driver is crashing while restarting. What GPU do you have? I've mostly seen this with AMD GPUs, but lately I'm seeing it with NVIDIA as well. I'm not sure why it happens because it's just disabling and enabling the GPU driver like in Device Manager, and installing a new driver also does the same. In NVIDIA's case, maybe it needs a delay between disabling and enabling the driver like it used to have. Can you try the restart64.exe that comes with CRU 1.4.1: https://www.monitortests.com/download/cr...-1.4.1.zip
