Your assertion doesn't bear out my experience LR. I'm typing this on a box connected to a 32" Samsung lcd tv. According to the pc, the native resolution is 1360x768.
In practice, this stretches the desktop vertically & shrinks the text to the point that it bothers me. I resize it to 1024x768 & see no degradation in quality. Certainly the refresh rate can blur or sharpen things a good deal. For me, playing with the resolutions & refesh rates until I was happy was the way forward.
