In Reply to: RE: Plasma run hotter then lcd's ? posted by Rick on July 28, 2009 at 05:43:33
My take:
LCDs don't have the shadow detail or deep blacks that plasma does, although they often look a bit brighter in "torch" mode in showrooms at BB or Fryes. I also don't care for the motion lag with LCDs. Those factors alone would do it for me.
The heat just isn't an issue for most plasmas - modern displays will go well over 100,000 hurs to "half original brightness", which is probably far longer than you would use the set in real life. Also, Panasonic and Samsung are firmly committed to plasma production.
I've worked in a room full of Panny plasmas and they didn't raise the room temp at all.
They are a bunch of myths out about plasmas, so take short plasma life with a grain of salt. It doesn't seem to be true for the vast majority of users.
I watch a lot of film based material, which looks much more natural and "film-like" on plasma displays. LCD is fine for most video sourced material, and they've come a long long way in the past few years. But the plasmas look better to my eyes and lack the shortcomings I perceive with LCD. However, your eyes may different from mine, so you may prefer the LCDs.
Whichever technology you choose, don't let plasmas running warmer be the deciding factor - it's insignificant in the long run.
Follow Ups:
I still prefer my 4 year old plasma to the LCD TV's I've seen recently for all of the reasons you mentioned.
Additionally, plasma has become more energy efficient and depending on brand / model / size, most dissipate only slightly more heat than LCD's and some are on par. A few are still energy hogs but this is not the norm.
I have yet to see an LCD that doesn't shift color slightly as you move slightly off center to the screen. Try it sometime at a store. It is most noticeable while observing skin tone on a talking head - a close-up of a news broadcaster for example. While much improved vs older sets, this phenomenon peculiar to LCDs still exists today.
I would say even 10 degrees off center noticeably decreases PQ with LCD, and especially brightness. 20 degrees is ridiculous.
People should remember, as was pointed out already, that plasma power consumption is all over the place depending on what's being displayed. LCD power consumption is constant. So to compare actual power consumption (manufacturers' numbers are usually max.), you'd need to use a kwh meter over a fair time with the material you watch with the plasma...not really practical, and may be an irrelevant result to everybody but you.
For example, my Pio Elite 60" consumes from 160W to a bit over 700W, and I use it in full power blasting mode (I don't mean torch mode, but in no-power-saving mode for best performance). In the summer I can feel the heat from the front of the display, but the back is "cold" and none of the four fans have ever come on (I presume they work...).
