Blk Scr w/ "invalid signal" box

[DtD]

from the sound of it, your monitor (a TV in this case) is getting a resolution that it does not support. You can change the "screen" entry in your "My Documents/Penumbra Overture/Episode1/settings.cfg" using notepad. (It has been a while since I played, but I think this is unsupported and may cause some graphical glitches on occasion.
