Blurry 2nd screen

This sounds like the montior is scaling the image, so it is not running at the native resolution of the monitor. This will make it look blurry.

The monitor should be running at 1920x1080 but I can't check this from your logs as you don't have a screenshot of the screen resolution in there. Can you check you are running at the native resolution for the monitor? Also are you connected through VGA? If so, you might need to do an "Auto adjust" to resync the VGA.

Hi Wim,

thanks for your reply.

Monitor 3 = HDMI = no problems (resolution 1920 x 1080 = native)
Monitor 2 = VGA= blurry (resolution 1920 x 1080 = native according to manufacturer although the setup page (see screenshot) indicates that that is not native and that best resolution would be 1280 x 1024)

Also tried to auto adjust but very little effect.

When I switch monitor 3 and 2, monitor 3 with VGA has the same problem.

Strange thing is that it went well the first 2 weeks, and than all of the sudden the image got blurred...

I think this is due to interference on the VGA cable. VGA is an Analog signal so interference will cause the display to look blurry and I think this is what you are seeing.

And how can I get rid of this interference, it's a new cable...
