Custom Resolution Utility (CRU)

I have a pretty serious problem that I've been trying to figure out for the past few days, and I'm really hoping you can help.

Background: ASUS G533ZW (3070ti) laptop with a 240hz refresh rate display in it. Windows update dropped a few days agi, and suddenly, after one year of everything being fine, my refresh rate options completely disappeared. Can only see 60hz in Windows, and in NVIDIA as well. If I try to force a higher hz in NVIDIA custom resolutions, it goes up to 160, and after that, the monitor goes black when I try it. I tried cleaning the system of drivers(ddu) and reinstalling them, as well as performing a clean install (format+reinstall windows), but the issue still persists.

I found your CRU tool and hoped to somehow be able to force the system to run at 240hz. I can confirm that I have the right values in the displayblock that I have (2560x1440 @ 240hz), however, I can't set a custom detailed resolution to anything above 162hz, as the number turns red. I tried creating custom extension blocks, tried importing one as the sticky post says, but nothing works, as the values are there and actually what I'd want them to be, yet I still can't set the hz in the resolution that high. The detailed resolution tab states as well: Range limits 60-240hz, 389-389khz, 1070mhz.

Enclosed I'm attaching the EDID file.

If you have any idea of what could be wrong, I'd really appreciate the help!

You need to add the detailed resolution inside the DisplayID extension block, but there's no point in doing this unless something is wrong with the EDID because the monitor should already define the correct resolutions. This sounds like a graphics driver issue. If the laptop has switchable graphics, you also need to install the Intel graphics driver.
