can you change the White Balance settings eather on the PC or the tv.
did you check the settings on the tv, maybe a power outage/surge reset the tv colors?
to me it sound like the White Balance Gain and/or Bias Green setting is set way too high, but is it on the TV side or PC side.
I have a Toshiba plasma TV (model # 50HP66) and I have been using it just fine with television, DVD, and a PC running Windows XP (using the TV's VGA input). Recently, within the last month or so, if I try to use the VGA input, the screen is tinted green. My computer works fine, I even tried re-installing windows and re-installing the drivers for my graphics card to see if that would work, but the screen is still tinted green. Has anyone else had this problem? I'd appreciate any help/advice that anybody could give.
