I just bought a 32" Sharp High Def LCD for the bedroom. Picture is great when hooked up to my high def cable box with HDMI cable. However there seems to be one annoying white pixel when the screen is dark. As I have not owned a LCD before, I was wondering if this is normal. When watching T.V. the dot is not noticable. Also the HDMI cable, when tugged slightly, disturbs the picture (eg, turns the screen to green for a second or two).
