I'm using Ubuntu 11.04 on my laptop Samsung QX410. I also have Philips 221EL display. I want to use this display as the main one (instead of the laptop's one). But when I use it, the screen looks blurred. I thought that was a graphics driver-related problem, I spent much time trying to install the proper graphics driver. Finally I managed to do this (at least 3D effects work), but the display is still blurry. It is blurry while using any resolution - I tried a lot of them, including recommended 1920 x 1080 and refresh rate 60Hz. At the same time, laptop's display always looks OK. And the Philips monitor looks okay when using Windows, so it's an ubuntu-specific problem.

stupid answer, but: have you tried the "autoconfig" button on your monitor? (or something similar) –  marto Mar 31 '12 at 10:47
    
I did, but it didn't help... thanks anyway - I ended up using another monitor. –  itsmeee Apr 14 '12 at 12:57
    
Were you using a vga cable? I've noticed blurry output with vga compared to dvi/hdmi –  davbren Apr 28 '12 at 10:39
