I have seen a few monitors do this; my own moves over about 1/8" between fully cold and fully warm. There might be a hardware problem here, but I don't really know. However, it is possible to manually adjust the left/right picture (among other things) if you open the monitor up. The plastic screw to do this is reasonable well marked, and you will need a fairly long, non-conducting screwdriver. WARNING: Your monitor can kill you. A cathode ray tube acts as a giant capacitor; it can store about 50000 volts even when the monitor is unplugged. Touch the wrong thing and it will stop your heart. You won't even have a chance to finish fixing your display. Basic monitor adjustments are easy, but you MUST know what you are doing. Hope this helps -sam
