What model is the monitor?

This one here, so maybe I don't think you can get much information from it

You can't boot Windows in safe mode? DDU works in safe mode: https://www.wagnardsoft.com/display-driv...aller-DDU-

If the monitor doesn't provide scaling options, the only other option I can think of is using borders, but CRU doesn't currently support borders because they are almost never used, and the lowest possible vertical resolution would be 1650 instead of 1620. I need an export of the EDID to make that work.

Hi all! I have problem with CRU in Windows 11, however in Windows 7 it works good.
I have monitor without proper EDID (or it is broken) ViewSonic VG2030wm and native resolution of it is 1680x1050. Video card is very simple Radeon HD 5450 1Gb (without fan and without PCI-E power).

In Windows 7 in CRU I set 1680x1050@60 in "Standard resulutions" section and then I run restart64.exe, after that I have ability to set native resolution in screen resolution options of Windows OS.

In Windows 11 in CRU I do the same but somtimes after restart64.exe nothing happens and 1680x1050 doesn't appear in Windows OS settings and sometimes after restart64.exe I just see the black screen with mouse cursor only (that makes me to push the reset button).

Any help?

Windows 11 does not allow EDID overrides for monitors without a valid EDID. Also the first post says do not add the native resolution as a standard resolution.

If the EDID is broken, try using EDWriter to fix it: https://www.monitortests.com/forum/Threa...yID-Writer

Click "Read EDID," click "Yes" if it offers to fix the data, then click "Write EDID." If it says the display is write-protected, try to figure out how to get into the monitor's service menu. Usually the service menu can be accessed by holding one or two buttons down while powering on the monitor. If the service menu has a burn-in mode option, enable that. Then try writing the EDID again.

What port are you using on the monitor? Usually each port has its own EDID, so if the EDID is corrupted on one port, you can usually use another port. DVI would be preferred though.

Another option is to use an EDID emulator. If the video card has an HDMI port, you can use an HDMI EDID emulator with an HDMI to DVI cable. I don't see any that have 1680x1050 by default, but you will be able to use CRU.

These will give you 1024x768 by default which is a safe mode for most monitors:

This tool doesn't work - it says "No compatible display found". By the way now my monitor is connected with VGA-VGA cable. Earlier I tried DVI-DVI without CRU but it works in 1024x768 only mode (with VGA cable and without CRU it allows to work in many resolutions 1024x768, 1280x800, ... 1366x768 ... , 1440x900, 1600x1200 but not in native 1680x1050)

I discovered only one way to make it work in native resolution 1680x1050 in Windows 11 - Uncheck "Use EDID" in "Catalyst Control Center" tool and set there maximum resolution to 1680x1050. But this solution works only before Windows 11 restart. After restart "Use EDID" is checked again and monitor works in wrong resolution.

How about use INF file to override EDID? https://learn.microsoft.com/en-us/window...itor-edids

Are you not able to use CRU with the VGA port? What does CRU show for each port? If it says Generic Non-PnP Monitor with no resolutions, then the monitor doesn't have a valid EDID. If it shows resolutions, you should be able to edit the correct native resolution.

That's what CRU does.
