    Intel 4400 3840x2160 Resolution Issues

    AStevens

      I recently bought a 4k Hisense TV.  When I connected my computer to the display, small green dots appeared across the entire display.  I tried updating my drivers, but nothing changed.  I looked at the resolution settings.  Recommended resolution for this display is 3840x2160, but when I changed it to 1920x1080, the dots all cleared up.  I tried all the other resolutions above 1920x1080 and they would have even more green dots than the 3840x2160 resolution.  Anyone know if this is a hardware problem or limitation?  I thought it was strange that the recommended resolution was having problems...

       

      Thanks in advance for your help.
