Hi!
I have an old 15" Philips LCD TV with 4:3 aspect ratio (1024x768) and the 7800GD connected via SCART RGB cable. Unfortunately, every time I turn the console off and on, the TV sets the aspect ratio to 16:9 so everyting is squashed. I've found there's a pin on the SCART connector which tells the TV what aspect ratio to set:
(This is from the TV's service manual.)
Is there anything I can do or can the firmware be updated to set the correct aspect ratio?
