LG develops plasma TVs for high-altitude viewers
LG took note when a vendor pointed out a constant whining sound emitted by their plasma screens when used in the mountains. Large plasma displays operate via a gas trapped between two layers of glass, which expands at higher altitudes. As the gas expands and begins moving more quickly, it heats up and causes a buzzing sound, which is traditionally countered by constantly running cooling systems that end up emitting even more noise. LG solved both problem in its DU-42PX12X, a 42-inch widescreen plasma that simply uses less gas than its low-altitude counterparts. There are a couple of drawbacks with the unit, namely its ground-facing connection ports which require awkward positioning when connecting periphery devices, and some rather lackluster on-board speakers. Still, high-altitude users can opt for an occasional handstand installation adventure and an external speaker system and likely end up a lot happier with a less noisy plasma.
