When I first power up RasPlex the image seems to be just a little bit too big for the screen. Normally I'd fix this by changing the overscan values in config.txt, however this seems to have made no difference: Whatever values (even really big values) do not seem to have an effect.
I read that OpenElec may have an alternative way of adjusting the screen borders - What is the correct procedure for dealing with over or underscan?
You could always calibrate your video output in the rasplex GUI. If memory serves me right, it's in Preferences -> System -> Video output -> Calibrate video. I always have to do that with my old TV
