MCE seems to have several configuration sections for calibrating the screen size overscan, brightness, contrast, color and sharpness. Except that it doesn't actually let you change any of these, expecting you to adjust your device instead.
However my TV doesn't let me change the overscan settings or set where the visible edges of the screen are. So a few pixels on the top and bottom and a few dozen pixels on the sides of the screen are outside the viewable area, including some of the MCE controls.
XBMC lets you adjust the visible screen limits by offsetting the top left and bottom right corners using a calibration tool, and everything from the OSD to the video output is adjusted to fit within this area.
Is there really no way to adjust MCE so that I can see all the video and controls?
