Windows 10: Windows not reading monitor EDID

Hi,

I recently got a new monitor, an Eizo EV2750, which Windows only recognizes as a generic PnP monitor.

I've tried connecting it thorugh DisplayPort, HDMI and DVI without any luck. The often mentioned sollution, to unlplug everything and wait 10 minutes, does not work either.

The graphics card seems to read the EDID however, as in nVidia control panel it displays correctly as EV2750. Same thing with other applications, like DisplayCAL which I use as my color management system.

Seems like it's only an issue with Windows. This issue, however, also means that I can't get full functionality from the monitor. For instance, the ambient light sensor does not work (which is typical when Windows doesn't recognize the display properly).

Does anyone have any sollutions to this?

:)

 

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.

Win10, display turned off, the resolution is only 1024*768, when turning back on, resolution is normal

the monitor turned off, windows 10 change the resolution to 1024*768, turned it back on, windows 10 changes the resolution to 1080P or 4K. each monitor has its own EDID information stored in win10 registry. remote software doesn't have other options some
time.

it looks like the bug (i guess) of Win10 is if it doesn't detect a realtime physical EDID, it will just go to 1024*768. not sure how i can set up my monitors to change that while it is turned off.

 

It seems you need a monitor "driver".
Monitor drivers aren't really drivers at all, just identification data that the OS can read and file to identify the device correctly.

Most monitor "drivers" are offered up by Windows Update. But if your monitor is too new to be included in the vast list of Windows drivers, then it may be a while before it shows.

If your monitor came with a disk (CD or DVD) you can check to see if there is a "driver" offered there.
Otherwise, check the manufacturer's website.

 

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.

 

Did you check to see if there was a driver of some sort?

If you think that Windows can't read the EDID from the EEPROM then you could check for a monitor firmware update (bug fix), or it could be the monitor is defective.
