Hi. I have used CRU for a few days with no problems but today the Restart64 black screened me completely. I fixed it just by safe mode uninstalling graphics driver, restarting, then reinstalling driver. Now every time I create a resolution then proceed to use restart64 I get the black screen and have to re do the entire thing. Do you know what can make restart64 work for again like it used to. Please help.

Please provide more details. What video card and monitor are you using? What resolution are you adding? You shouldn't have to reinstall the graphics driver. Just run reset-all.exe and reboot.

Try different timing parameters. If that doesn't help, then you'll have to use GPU scaling.

Hi!
I have a Samsung CHG70 monitor which is hdr600 certified, connected via displayport. When enabling HDR in windows or in games, the colors looks really washed out.
I've already tried setting the dynamic range to full in nvidia control panel, but that didn't work.
It looks like exactly like in this video, but as shown in the video, hdr looks good on ps4 and it looks terrible on pc.

These are the default colorimetry and hdr settings in cru.
Windows is running the latest version (2004). Can anybody help me fix this issue if its possible?

Which timing parameters would you recommend? I have no idea what I should enter in.

I can't recommend anything other than the timing presets because I don't know what the monitor will be able to handle. It's mostly trial and error, and if the timing presets don't work, it might not be able to handle the resolution at all.

I don't know if that's fixable with CRU unless you want to remove HDR completely.

I'm trying to reduce the G-Sync (compatible) range on my Samsung Odyssey G7 32" but can't get it to work (2560x1440 @240Hz display)

I watched a bunch of videos, read some tutorials but no matter what, I can't get it to do any changes.

CRU shows my active resolution as 2560x1440p @144Hz, but the display is running at 240Hz according to the Nvidia CP (and Windows AND my OSD): https://i.gyazo.com/71177be36009054498cc...6ffb0d.png

Creating custom resolutions with 240Hz and anything near the pixel density of 1440p doesn't work either (manual and with presets) https://i.gyazo.com/10b62a2b2fab314c2b23...71684f.png

Reducing the refresh to 144Hz didn't give me any results either.

Any ideas?

edit: just in case: yeah, I used restart.exe do save the changes, ran CRU as admin, driver version 451.85, displayport

240 Hz is in the second extension block which CRU can't read because for some reason NVIDIA's driver won't provide more than one extension block. To add resolutions beyond 655.35 MHz pixel clock, you need to use a DisplayID extension block. You might need to delete the default extension block and add a DisplayID extension block manually to make changes work with NVIDIA.

Thanks, I got it to work!
