What are the symptoms of “altitude sickness” in plasma display panels operating at or above 6000 feet?
There is very little difference in visible picture quality. The chief high altitude symptom you’ll detect will involve your plasma televisions’ operational noise levels. Because of the increased pressure on the gases contained in its glass substrate, the unit must work harder to cool this display element. So, if your plasma TV set has fans, the fans will be significantly louder because they’re running harder. If your Plasma TV utilizes a convection cooling system (one without fans), then you’ll notice something akin to a buzzing sound emanating from its rear panel. Another thing to consider with respect to altitude and plasma TV is longevity: Since PDPs work harder at higher elevations, they will not last as long up high as they do down low. So, what does all this mean for someone living in Denver, CO, for example? At 5295 feet, Denver lies well under our new recommended limit of around 6500 feet. Pioneer states maximum altitude of 7500 feet. Panasonic now states maximum altitude at 78
