Windows 10: How to get to know the current settings for the external display

I have a special display whose EDID gives only one modeline.

Some lines from the EDID:

Identifier "YongXing "

ModelName "YongXing "

VendorName "LZT"

# Monitor Manufactured week 12 of 2017

# EDID version 1.3


...

Modeline "Mode 8" 147.80 1080 1180 1185 1355 1200 1206 1209 1212 -hsync -vsync



I connect this display with HDMI cable to Windows 10 laptop.

Windows knows perfectly how to use this display. By default it uses the resolution mentioned in the modeline: 1080x1200 90Hz.

When I uncheck "hide modes that this monitor cannot display" from display settings, I can make Windows also use resolutions

800x600 90Hz and 640x480 90Hz.


Is there any way to know how Windows controls the display when it uses these lower resolutions, i.e. what are the modelines that Window sends to the display?


I have tried several tools to tweak the modelines, but without success: Moninfo, Dxdiag, Powerstrip.

Those tools only show the EDID modeline.

Projecting to an external display

Hi,

Thank you for posting your query in Windows 10.

I understand that you are unable to use external display with windows 10.

This usually occurs if the video driver was not installed properly or not configured correctly.so I would suggest you to reinstall the drivers in compatibility mode and check if it helps.

I suggest you to follow the steps below and see if it helps:

Uninstall Display Adapter drivers

I suggest you to uninstall the display drivers and reinstall them in compatibility mode.

To uninstall the driver, follow the steps below:

• Press Windows key + R
• Type devmgmt.msc
• Right click on the driver you want to uninstall
  
• Click on Uninstall
• Restart the system

After the computer restarts, install the driver in compatibility mode.

• Select the setup file
• Right click on it and click on
  properties
• Click on Compatibility tab
• Select the operating system
• Click Ok.

Hope it helps, do get back to us if you need further assistance with Windows.

Hi,

When the computer restarts the driver re-installs its self. and also how would I go about going into compatability mode. Would this be through internet explorer?

Any insite on this would be a great help.
