I hear that these plasmas have different resolutions or something to that effect, what resolution is ideal?
I also hear that you have to have them recharged. Is this true and if so, how often and how much?
Can I expect a 10 year life out of one of these?
Are they prone to any particular problems, like image retention?
Thanks in advance!
A. 42" plasmas have one of 3 resolutions:
1. 852x480 progressive
2. 1024x768 progressive in 16:9 format (nonsquare pixels)
3. 1024x1024 interlaced in 16:9 format (nonsquare pixels)
The second and third are often called HDTV, eventhough they clearly are not. HDTV requires a minimum of 720p, which is 1280x720. What manufacturers actually do is they lie about it.
🙂 They completely ignore the horizontal pixel number (1280 pixels) and just fixate on the vertical (the 720 pixels).
B. No, recharging is a myth told to customers by some uninformed Circuit City and Best Buy sales people.
C. It depends. The current generation of plasmas have a halflife of upwards of 60k hours (ie. The excellent $2500 Panasonic 42PWD6UY). That means, they fall to roughly 1/2 brightness in 60,000 hours. At half brightness, they're still quite a bit brighter than you'll get with a typical tube TV. Let's take a look at some basic numbers. Let's say you pretty much watch TV and do nothing else with your day. Let's say you watch 10 hours a day, 7 days a week, 52 weeks a year, year after year without skipping a day. That means you're watching 3640 hours of TV a year. With a 60k halflife, this plasma set will experience a half brightness in roughly 16.5 years. If you want to wear it down to 1/2 brightness in 10 years, you would have to watch 16.5 hours of TV a day. I would be very sad for you if this was the case.
D. Yes, they are prone to some image retension. This being said, the current crop of plasmas are far FAR better than those even a year or two ago. They can still burn in, but if you use common sense, they will not. Simply calibrate the brightness and contrast to proper levels. Don't leave a static image for hours. Just basic common sense. Burn in is related to overall plasma life. So, the longer the plasma panel's halflife, the more resistant it will be to burn in. These 60k life plasmas are much more resistant to burn in than the 10-20k hour ones that stores originally had. If you pick a good brand (ie. Panasonic's latest are great panels, NEC makes great ones as well, as does Pioneer), they'll be noticably more resistant to burn in than say, the Gateway ones.
