I can see the point that the interior may degrade because of more use
than the edges, but leaving a static image on a screen while in use burns in at an incredibly faster rate than the dimming issue of the middle 4x3 with black bars. I have been over peoples house that had older plasmas and LCDs and had the gray bars on for a few hours. Even when the TV was only a few weeks old we could see bars on the side after watching something for a few hours. If they watched a 16x9 show for an hour or so it would clear it up. Still not sure about how much damage it caused for the long haul, but it is clear gray bars are bad and are much worse. Gray bar effects are notice after several hours while the "dimming" issue of the center area takes years of use to notice depending on usage. On my Panasonic Plasma I figured out that the half life was almost 18 years based on only 30,000 hours to half life instead of the spec of 60,000 that they say which would mean 36 years for me. Give that I watch mostly HD and in a year most everything I watch will be in HD anyway, the dimming effect is a non-issue. Also, most of the consesus out there seems to be that the burn-in on plasmas has been addressed pretty well by the quality units, but the pre-2002 units stunk. Basically, if it gets really hot, you have a POS that is going to burn in.

I forget what those options are in my 622 menus, but FWIW, �any gray bars are much less prone to cause burn-in than black bars (if you're given the option to choose between the two....) LCDs, DLP and most LCOS/SXRD are usually quite immune to burn-in, as a rule. Hmm, I'm wondering how black bars can cause "burn-in" since black seems to be the lack of anything on the screen. That would be because that black area (in a plasma display) does not deteriorate over time, therefore when a screen-fillling image occurs, the areas that were black would be brighter than the center.

Then, after a while, any time you watch a full 16:9 | image, the burn-in will be all too obvious. You will see a bar effect on | the right side and left side of whatever you are watching. | | If you watch a lot of 4:3 content on your 16:9 plasma or CRT TV, it's better | to have grey bars than black bars on the sides of the screen so that the | pixels there will age at about the same rate as the pixels in the center of | the screen. WTOV-DT puts dark gray bars on their 4:3 newscast. But they do it badly. There is a narrow black bar in between the gray and picture on each side. It's only a few pixels wide. It would probably end up being more annoying for those with displays vulnerable to burn-in. Broadcasters should transmit programs using a format made that matches the program. That will let the viewer and/or his/her display decide how best to display it (anamorphic-like stretch, pillarbox with black, or pillarbox with gray). -- |WARNING: Due to extreme spam, googlegroups.com is blocked.

But if the program provider sends them a signal that is always in one of the 16:9 HD formats, it is very unlikely that DirecTV or DishNet or Comcast or Verizon or anyone else is going to detect that _some_ programs are coming across pillarboxed in that 16:9 format mode and modify it to be stretched. If there are any other programs in real genuine HD (and I would think at least some would be for a channel named "History HD") then it almost certain to be the History HD control room where the stretching is happening. The "decision" to stretch would have to be done in the device that is converting from SD to HD ahead of their master control switcher (probably automated).

I agree you should complain to the provider as well. This is because your business relationship is with your provider. But, consider if this were an OTA TV station, and that TV station did this. Would you think your complaint should be focused on your provider? I presume History channel (I don't get it because I'm too cheap) includes commercials. Take note of which companies sponsor the programs, especially the stretched programs. Include letters to those sponsors as well. It's not hard to find out who most of the TV program sources are. When it is a problem with how they transmit the signals, there is no point in not letting them know directly. Depending on a satellite or cable provider to do something about it is only going to dilute your complaint at best. Are you going to tell your provider that you will switch to another provider in such a case? You know it will be the same with all of them. You can also complaint to your TV manufacturer for failing to provide a feature that "corrects picture problems created by incompetent programmers like History HD". | One can also participate in one or more forums at http://www.history.com That, too. But the people that matter might not be reading it. If AVSFORUM wasn't using such an awful web program (which, unfortunately, most web forums use this or other programs like it), I'd suggest asking them to add forums for each TV program there. If I get around to it, I'll call the Dish sales department and ask them if they have fixed History HD, yet. -- |WARNING: Due to extreme spam, googlegroups.com is blocked.
