Has anyone else seen this problem ? My PC (VGA plug) worked fine on the screen at first, but now in wide screen the right hand 20 or so pixels are cut off and the image is shifter to the right slightly. If I change to 4:3 mode then the offset gets even worse and I get a black vertical bar down the middle of the screen. Tried switching everything off and on, and changing PC resolution but can't seem to get it to display centrally. Any help appreciated..
