Chess, I just received the Panny ST50 (like 15 minutes ago). I've got blinds on the right side of the room, I will let you know how glare is tomorrow during daylight.

There is a little bit of glare from a lamp next to the couch, but it is a dim reflection. Not really bothersome for TV watching. There is more glare from the glossy black bevel than the screen.

If you have bright lights directly behind the sitting area, it could be a bit of a problem.
