Aspect ratios for plasmas and burn-in

Hi Everyone,

I am new to HD world and got my PDP SAMSUNG T5084 recently. As I went through the manual it suggests to limit viewing in 4:3 (e.g. Standard Def channels) as much as possible so that no black/grey stripes are left on sides of screen for long times. But I don't really care about viewing SDTV but I was wondering about aspect ratio settings while viewing HD movies.
Yesterday I watched Bourne Ultimatum and apparently movie comes in higher aspect ration than 16:9 (maybe 2:1). So even if you stretch screen vertically I still get small black space on top and bottom. I am guessing it just as bad as watching in 4:3 with lines on the sides.
How do other people watch HD movies on plasmas if aspect ratio doesn't allow to fill the whole screen? Does it mean if you get plasma than burn-in is unavoidable?
Any help would be appreciated.

I know this won't help you at all, but you asked how other people deal with it. My PDP when stretched vertically, does not show any black bars. So I can't really help there. I personally feel that it's ok to allow the black bars sometimes. Remember is says to "limit" not prevent completely. I'll watch some movies in the 2.40:1 letter box and sometimes I'll stretch it out. I never watch 4:3 just because I can't stand the bars and I don't care if the people look fatter than they should, but that is not the case with others who refuse to stretch. It's personal preference.

I would limit 4:3 or 16:9 (2:40:1) during the 1st 100 hour break in period. After that, I would not be too concerned. If you wind up watching more 4:3 SD channels, just change the channel during commercials once and a while if you watch for hours on end. But you would probably do this anyway. Burn in is exaggerated a bit now a days (especially with current models). I have been gaming and everyting else on my plasma for 2.5 years and love it. Many get Image Retention and burn in confused IR is much more common, but that will go away quite fast (usually when you change the channel) and is not an issue. Just be causious during the 100 burn in and make sure to take it out of "torch mode" and you will be fine..

Did you mean Dynamic Mode for Samsung PDP by "torch" mode?
What's the best way to find out optimal settings for initial 100 hrs of use?

also make sure when you purchase or rent dvd(or hddvd) that you get the widescreen version. that should eliminate the bars on the top. Widescreen movies fill up the whole screen on widescreen tv's.

I am not sure about the Samsung settings, but it sounds like it to me. On my HP/Panny, Vivid is the default and the highest setting. It has things like contrast and brigtness cranked wayyyyyyyyy up. I just set it to Standard (in between vivid and cinema) and tweaked it a bit from there. You eyes will thank you as well.

Not always true and often not the case.. In addtion to Widscreen (16:9), it also depends on the aspect the movie was shot in. If say 1:85:1 or 1:78:1, it will fill the entire screen. But many movies now a days are also shot in 2:35:1 or 2:40:1 for example. These will still produce quite a bit of "bar action" on the top and bottom...

Exactly, in fact filling the whole screen is typically the exception across most movie formats. Unless that's all you watch, I would not be too concerned about burn-in whenever you watch a 2 hr flick.
