I tried hooking up my laptop to a TV set that only supports 1080i resolution, and when I tried launching Superbrothers, the game went to ****! It's like the resolution was dumbed down to 100x200 pixels. Adjusting the resolution does nothing for me; neither does deleting the game and re-downloading it. Every bit of text looks out of focus. The moon looks like a SNES sprite. What could have gone wrong?
What kind of graphics-card do you have? I had the same problem with my Radeon when I hooked it up to the TV. What I had to do was to get into the Catalyst Control Centre and change the texture-settings, as they've been set to the lowest possible for no discernable reason. Happens from time to time when I hook my computer up to my screen.
