e6500 - WUXGA Changing screen resolution

I wasn't calling you a liar, only pointing out that it's not a good way of showing your problem

 

The reason why your results on anything but 1920x1200 suck -- it all relates to the Nyquist-Shannon Theorem. When you scale the resolution down, your LCD is essentially sampling a lower-bandwidth signal.

Nyquist's theorem states that the sample bandwidth must be at least twice that of the bandwidth of the signal, or else aliasing will result.

A resolution that should work very well would be 960x600, which corresponds to the theoretical Nyquist rate, and should not give you aliasing. 4 pixels (2 x 2) on the WUXGA screen will correspond to 1 pixel.

Anything else, essentially, is bound to look like garbage with aliasing.
