Windows 10: How to force output to monitor with invalid EDID?

A fairly old 27" tv stopped detecting signal via my pc's display port, but kept working on vga. It is dual-booting windows 10 and ubuntu. It shows no BIOS screens, but once ubuntu starts loading, it would detect and output a signal, albeit the wrong resolution.

From ubuntu's logs I found that the EDID was not valid, but ubuntu was guessing an output mode and trying anyway. The BIOS and Windows don't apparently do that if they don't get an EDID, and output no signal at all. So I'm stuck with crappy vga for running windows 10.

Under linux, fixing the problem was a simple matter of a few lines in terminal to add another output mode to switch to. All I can find from Microsoft is some complex stuff about creating an .inf file with data from the tv's manufacturer. That should not be necessary.

Importing monitor.inf file will fix the edid problem ?

Hi,

An incorrect or invalid EDID (Extended Display Identification Data)
info on the monitor's EEPROM (electrically erasable programmable read-only memory) can lead to problems such as setting incorrect display modes. We suggest that you contact your monitor manufacturer for assistance in updating or overriding an EDID using an
INF.

For additional reference, please check the links provided below:

Let us know if you need further assistance.

Regards.

 

EDID Display(Monitor) manufacturer's name

Or Do not Use EDID, Use other way direct get DIsplay(Monitor) manufacturer name also OK.

 

Windows not reading monitor EDID


That's what the EDID does. It's monitor identification data stored in the monitors EEPROM. Windows fails to read that, while other software works.
