I have been trying to get my LG-34UC88-B screen to run at 75Hz and it only shows 30Hz and 60Hz.
I have another drive with Windows 10 and can easily change the LG-34UC88 Refresh Rate to 75Hz. Confirm 75Hz using the UFO Test.
I have an AMD Sapphire Nitro RX570 graphics card using the Orinoco Framebuffer.
- I tried using carpentryplus25's guide here but I did not ending up needing to make any changes as the Orinoco FB is a perfect match for my graphics card.
- I have also tried my luck a few times with SwitchResX but I can only get it to 67Hz which doesn't make sense to me when it can run fine on Windows 10 at 75Hz. I've tried with and without my patched DSDT for my graphics card and 75Hz is still not an option.
- I've also looked into Display Overrides and have added in the appropriate DisplayVendorID-1e6d and DisplayProductID-76e4 with the correct matching values from the EDID file and that didn't change anything.
- I previously was using the 15,1 SMBIOS and now 18,3 but things remain the same.
- I've attached the EDID file for the LG-34UC88 from SwitchResX.
I would really like to get my LG-34UC88 running at 75Hz as 60Hz puts a lot of stress on my eyes after a few hours of working.
Any help would be greatly appreciated
