I looked at all of these and couldn't really see anything. The tiny text of 28 and 149 looks like it's oversharpened a bit. Maybe, just setting it on a lower opacity could halp with that. Sometimes I think, it's just the font at a ceertain size that makes it look pixelated or oversharpened, or rotating it like you did in 120. But, as I said, apart from the tiny text I couldn't see anything pixelated.

Hope that helps you in a way.

Oh, I just remembered something. It could indeed be your monitor. A while back I had some problems with mine. In the middle of the screen everything looked fine but pushing an iage to the left or right it looked all squished and blurry.
