Windows 10: Flickering Monitors Benq BL2420PT

I have two Benq monitors (connected on surface dock with displayport cables), which have had issues with Windows 59Hz automatic setting since day dot, but resolution was simple in setting Hertz to 60Hz. New Surface Laptop 3 will not hold this setting as below article seems to indicate that both 59Hz and 60Hz save 59.94Hz as the refresh rate now and display 59Hz. I do not know why this worked previously, just did and neither the generic driver or benq driver help the issue. I have tried with a DVI cable and that display is fine, but only allows 1920 x 1080 resolution.

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!

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.
