display 2 flickering?

Hi,



Thank you for writing to Microsoft Community Forums.

1. Since when are you facing this issue?
   
2. Have you recently made any changes on the device?
   
3. What is the make and model of the computer?
   

Here are the few steps you can try to fix the issue.

Method 1



Make sure all connections for the monitor are properly connected.

Check the cable at both the computer and monitor ends. If tightening it down or reconnecting it doesn't fix the problem try replacing the cable and check the status of the issue.

Try connecting on a different monitor and check the status of the issue. If the issue still persists on the other monitor.



Method 2



You may refer the article Troubleshoot screen flickering in Windows 10
for more troubleshooting steps to fix the issue.



Hope it helps.

Screen Flickering

Return that card for something else. I've heard of many issues with Asus Direct Cu 7970's. You could try finding a different monitor to see if your monitor is the problem, but I doubt it.

**I though you tried differnet cables. Buy a new cable and try it. Get a Dual Link DVI cable.

Here's a list.

1. Uninstall and reinstall video drivers.

2. Replace cable

3. Try different monitor

4. Try different video card

5. Replace video card.

If you can do any of the steps above, just skip to step #5.

 

Monitor Dim and Flickers

I have a new Dell Inspiron 3668 cpu and running it with my old Dell ST2010 I have run the windows "troubleshoot screen flickering in Windows 10" from Windows help. When I go to task Mngr. it still flickers. So, I uninstalled the display driver as suggested
and then ran the "Check for updates". The problem still remains. Any further suggestions?? My next step is to just replace the monitor and assume Windows 10 will not run it!
