You don't need an extension block. You only need one detailed resolution for 1366x768 @ 60 Hz and nothing else.

"Non-PnP" means the graphics driver couldn't read the EDID, so there shouldn't be any resolutions in CRU by default.

I tried this and gave me bsod "system thread exception not handled"

That's a driver bug then. What driver version do you have installed? Try installing the latest NVIDIA driver with the clean install option.

The real problem is the EDID on the monitor is probably corrupted, so it's not being detected correctly. I don't know what you can do if the driver won't accept an EDID override. Maybe a cheap active HDMI-VGA adapter would work around the problem.

i can force enable Dolby vision on my Apple Tv 4k.

Can the same be done using CRU?

i only need the TV to go into Dolby vision mode, unfortunately there is no control on the TV to force enable DV.

Dolby Vision is proprietary and requires a licensed device and software support. Have you tried this: https://www.microsoft.com/en-us/p/app/9pltg1lwphlf

currently I'm using Lenovo Ideapad 500-14ACZ laptop switchable graphics running Windows 10 latest version 20H2, since my LCD replaced my max resolution stuck at 1360x768. I use CRU to try forcing to get 1920x1080, the program runs well, no error also restart GPU successfully, but I don't see the resolution, anyone know why?

I’m experiencing an issue with CRU where my edid is showing a blank serial number after changing my freesync range. I’ve used a couple utilities to view the edid from both windows and Mac and see that the serial number field is blank/0 while the serial number (numeric) field is being edited by cru. This is all causing display arrangement to be totally screwy on my laptop since it seems it’s no longer able to tell the displays apart

On my Mac, I see:

Quote:EDID version: 1.4
Manufacturer: ACI Model 27a7 Serial Number 0

on windows in MonitorInfoView I see an empty serial number column and values in serial number (numeric)

Displays are asus mg279 if it makes any difference

What version of CRU are you using?

Im using the latest nvidia 461.09 drivers. this problem only started after I switched to nvidia 750ti. Last time while im using amd 6570 the native resolution is being detected just fine.

Try unplugging the monitor's power for a minute just in case it's a firmware glitch.

If that doesn't help, try importing this file with CRU (and enable "Import complete EDID"):

Can you try adding a lower refresh rate like 1360x768 @ 55 Hz? If that doesn't show up, then the driver is ignoring EDID overrides for some reason. Are you sure it has switchable graphics? The specs say it has an AMD CPU and GPU, which usually aren't switchable. You might need to upgrade the graphics driver.
