Custom Resolution Utility (CRU)

[vigan1]

Thank you guys. I think I know what is going on.

I updated the bios, then my laptop changed from default using "Generic PnP monitor" inf, to "Digital Flat panel (1024*768 60Hz)" inf, after a fresh windows install. Which is in itself weird, since my laptop use the surface book display and the resolution on the desktop is still 3000*2000.

When I uninstall the Intel drivers, I can set back the "Generic PnP monitor" and indeed I see that the screen is 64Hz. But when reinstall the drivers, it get back to 52hz LOCKED automatically. It seems that the intel drivers default to the internal EDID of the screen (which was updated with the new bios). Intel choose and lock 52Hz and also select "Digital Flat panel (1024*768 60Hz)" inf in the device manager. On linux the drivers don't care and choose 3000*2000*59.99Hz.

The bios/Firmware update messed up everything.

Prior the Bios update I had a problem with screen flicker, then the manufacturer relased another bios to fix the problem.

With the 1st bios my monitor was identified as MONITOR/MEI96A2 vendor (surface book 13.5" windows update installed "SurfaceDisplay.inf").
Now with the 2nd bios it is MONITOR/MS_0003 so the edid/firmware was probably changed !!!

Do you know what I could do to get only the EDID or the screen firmware back but keep the new bios ?

Can I send you the bios and firmware file of the 2 bios ?
Can a windows EDID override fix the problem, or is it at a deeper level like screen firmware ?

Thank you and sorry it is not on the topic anymore...
