The excellent games coverage at the San Jose Mercury News site offers up a gamers buying guide for
HD TVs. Dean Takahashi discusses the basics every
HD purchaser should know, some technical issues with recent plasma and LCD advances in mind, and addresses the specific problems that gamers will face with their new purchases. From the article: "If you accidentally set your PS3 for 1080p resolution, when the TV can only support 720p, you get a black screen. The Westinghouse TV I used displayed a message that said 'invalid format.' To reset the PS3 to the standard AV format, you shut the PS3 off. Then you hold the PS3's power button down for about 10 seconds. It will reset to standard video. If you have the Nintendo Wii, you won't have to upgrade your standard/enhanced definition TV as the Wii's best resolution is 480p. It's thankfully simple, but you get a sixth of the pixels on screen as you do with a full HDTV with a PS3."
