Hi,
yes its supposed to be black, but in fact is more of a dark grey as good blacks are not its forte.
Have tried to use a res of 1024 x 576 but the bottom of the screen is missing. Have no idea what front and back etc settings to use. Have just been guessing and have not got close to 1:1 pixel mapping.
Have searched for 1:1 powerstrip settings for my projector but cannot even find a mention of it.
Cheers
Andy
