That would depend on how hard you hit the TV and how big the bar was... Impact is everything.

Black Bars for an extended period (more than 2 hours) are a no-no during the first 200 hours of operation this is known as the "break-in" period and when the new pixels do the majority of their adjusting during the panels entire lifespan.

...Just read this for the optimum care in new plasma ownership...

I'm talking about the SD, etc black bars.

So after the break-in, the black bars have no impact to burn-in?

If you watch a lot of SD material with the black pillar bars on the sides then that could over time show that the area where the black bars are shown for extended periods repeatedly would age slower than the center area.

I actually use the JUST mode with SD material myself and it is the best at filling the screen on my 2008 model than I have seen on any display before it. You could also go with the dark gray bars instead of black bars to avoid that issue if you cannot adjust to the JUST mode, but you likely can.

Another nice thing about my 2008 Panasonic plasma is that when I set my cable box to "Pass-Through" the source signal instead of converting it to only one HD output, the better scalers in the TV do a better job scaling SD signals AND the display will automatically remember to use the JUST mode with SD signals and use FULL mode with HD signals. That makes the process automatic and is a very nice feature.

I'm not sure how much SD I watch, I've only been looking for it since I started considering a plasma. Some movie channels also use top/bottom black bars with a logo.

I'm considering the TC-P50G20 (2010 model), I downloaded the manual and I don't see an option for gray bars. I don't really want to put up with switching screens all the time or stretched images. But I'm interested in a better display than my new 55 LCD.

My STB doesn't have a pass though.

mavrik... Ive had the 50" g20 for about 3-4 weeks now... I havent had any problems what-so-ever with any image retention from black bars, logos and/or video games. Its a great tv. You'll love it. Plus, id gladly sacrifice a few "stretched" images in order to have superior pic quality over lcd.

That option IS in the TV menus to use lighter bars. You just missed it.

What brand/model STB do you have? If it is a Scientific Atlantic STB it DOES have pass-through, but if a Motorola it doesn't.

Will 3-4 weeks (how many view hours?) show screen retention for non-bar static viewing? Only after a few days I'm sick of the LCD, makes me feel like I'm on LSD.

OK, I did miss it, it says it's for 4:3 mode only, which I assume is the TV setting and not input feed. This won't help much since I use 16:9 screen setting.

I don't know what brand it is, it just says VIP211, Dish network. Are STB interchangeable with the card? Or do they have to come out and do S/N BS? I rather go automatic screen displays.

I believe you can use a pass-through (might be called "By-Pass) setting on the DISH STBs but I never had them so not sure. Check the DISH network section here for more info help with the rest of that.

It is for SD which is almost always sent in the 4:3 format except on Showtime which often times uses the OAR (Original Aspect Ratio) of the movie. SO THAT is when you would need those gray side bars if you didn't want to use the excellent (IMO) JUST stretching mode.

I looked though the STB menus and didn't see anything that resembles a pass though, but I have missed things before I'll do a search to see what comes up with my STB model.

So your saying the TV will change the side bars to gray automatically with the 4:3 input signal even if the STB and TV is set to 16:9 out/input?

Looking at the remote for this TV it does have a format button, to cycle though aspect ratios. My current sets I have to go though menus and subs to change it, a real pain.

Going back to the black bars, you mention an aging difference over time. What kind of time are you talking about, 100 viewing hours? Things should be reference to viewing hours since everyone's TV on time is different.

How about this, am I being overly concerned about screen retention with black bars? I want the TV to last for the 100,000 hours the manufacture promises.

All from the link I provided....

I assume and I believe the advantage of the break-in slides is that you get each individual pixel being lit (aged) at the same intensity and each pixel using its entire range of color................You dont see very much sky blue in the bottom third of the screen while watching regular content.
Quote:
(1) Some obvious advice: Do not leave static images on your plasma TV screen for more than an hour. Turn off your unit when you are not watching it. Do not pause DVDs for more than 20 minutes at a time.

(2) Know that plasma screens are more prone to burn-in during their first 200 hours of use. When phosphors are fresh, they burn more intensely as they are ignited. This means that relatively new plasma display TVs are prone to "ghosting", which occurs when on-screen images appear to stay on the screen belatedly. This is a function of the high intensity with which new phosphors "pop," and this phenomenon usually "washes out" on its own, as the screen displays subsequent images. Displaying a bright, or moving snow image (as with a DVD or VCR with no input) will "wash" a ghost image from the screen in most cases. Many plasma manufacturers have installed anti-burn settings, which are monotone gray or snow screen settings which recalibrate pixel intensity levels uniformly - thus eliminating any image retention (ghosting). It is a good idea to run this type of program after the first 100 hours or so.
Quote:
(3) Adjust the CONTRAST setting at or below 50% on your new plasma TV. These days most plasma TVs are preset to either peak or very high contrast (also called picture setting on many TVs). This forces phosphors to glow more intensely, which decreases the length of time necessary for burn-in to occur. Our advice is to reduce the contrast setting to 50% or less for the first 200 hours of use. And, be sure to avail yourself of your plasma's anti-burn-in features.
Quote:
(6) Realize that quality matters with burn-in as with everything else. Purchase a plasma display that has really good scaling, so that you can watch 4:3 TV programs in widescreen comfortably. It is better not to display black bars on your TV screen for prolonged periods of time (especially in the first 200 hours), so you are probably better off watching most everything in "full screen" mode. This should not be much of a problem todays selection of widescreen HDTV and DVDT content.

Thanks, I read that thread a couple of days ago. It didn't specifically address black bars after the break-in.

If you consistently watch content in letterbox format you will eventually be left with a panel that has an area of slightly darker appearing pixels at the perimeter of the display...however, mixing the content up with full screen programming will eliminate this potentially unwanted side effect...

Do try to watch some HD content on your HD set........

OK, so if I do what I'm already doing, watch whatever aspect ratio (always different) the SAT is broadcasting in, I won't have any retention, correct?

I have HD SAT service and I only watch the HD channels, but they do broadcast in letterbox.
