But sadly trying those modified drivers on XB270HU ends up in permanent "no signal". While 3D vision is currently working, monitor "died". And because I had no clue, that this could be so severe, I did not do any backup....
If somebody will be so kind to help me... you can use this program http://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU
to download EDID from your monitor directly to .inf file. After unpacking archive, start CRU and first select proper active monitor in top left corner. Then pres Export button to export .inf file.
Hopefully this will be enough to fix my monitor....
CRU can not modify the hardware EDID of the monitor. Only the paid version of powerstrip and some ISP flash utilities and Linux can modify the hardware EDID. No damage was done. Also displayport's EDID is in the firmware itself and isn't flashable in this way, while DVI, HDMI and VGA (dsub) can be flashed directly.
CRU does not deal with flashing hardware EDID's.
They deal with EDID overrides which are custom resolutions that appear in windows as new display scaled resolutions.
An actual EDID file is 128 or 256 bytes in size. CRU overrides the hardware EDID in the monitor without touching it physically.
Only powerstrip and Linux, and some ISP based flashers can actually modify the EDID directly.
If the EDID on the monitor is actually damaged, CRU can't fix it. Only flashing through Linux can fix that.
Also CRU can not create display scaled resolutions on Gsync monitors. While it can create the resolution as see through windows, everything will be GPU scaled from the native resolution.
To reset windows to a default state, use the RESET-ALL.exe file in CRU and then restart the video driver.
The reason you are getting no signal is because you attempted to use EDID overrides from a monitor with a hardware scaler to a monitor without a hardware scaler (Gsync). Just run reset-all.exe.
You can also just download Wagnard's Display Driver Uninstaller and run that in *safe mode* and then reinstall the video drivers back in windows. DDU also wipes out any EDID overrides you made.
