Do plasma TVs work at high altitude?

I've heard that plasma TVs don't operate well at altitude. How about doing reviews on high-altitude plasma TVs? Those of us above 6,000 feet need the help.

Hi, Pamela. First off, it's true that many plasma TVs aren't designed to work at extremely high altitudes, and most manufacturers put a limit on the altitude at which they recommend operating their plasmas. Take a plasma higher than that limit, and you'll likely hear a buzzing sound after watching for a while as the panel struggles to equalize the pressure and keep itself cool. We spoke to a few of the major plasma makers and listed the maximum recommended altitudes, in feet above sea level, for their 2007 model lines:
Pioneer: Does not specify a maximum altitude.
An LG plasma that has an "H" after its model name is rated for 8,000 feet.
