I would be in Avsforum and Reddit.
I just purchased a commercial LG Flat Screen 2008 #42LC5DC. Didn't know it was a commercial tv. Guess I got taken.
I only use it for the HDMI and watch from my computer. When I go to the menu, the screen adjustments are grayed out and the horizon and other screen types are also grayed out. Tech support told me that it was made specifically for hotels and they couldn't give out the codes to change it back.
Does anyone have any ideas on how I can get the tv to go full screen.
