I was about to purchase a Mitsubishi Diamond 55" RPHDTV, when I read a microscopic warning label, which stated "do not exceed 15% total viewing time on 4:3 material, or screen burn in will occure", plus, the two hidious grey bars make watching 4:3 material very annoying (why not black?)Great. I watch just as much regular tv as DVD material, and no way can I deal with the dwarf-vision mode where 4:3 is stretched out to 16:9. Since I live in a technologically backwards area, where my cable company will support HDTV in about twenty years, and my apartment has no view for a dish, i'm screwed.
So, does anyone know if I can get a HD quality RP set with a 4:3 screen? If so, would it support anamorphic squeeze and progressive input?
Thanks.

Screen burn in is really more a function of how high you set the brightness and contrast on your set. Many people set their set in the highest and brightness mode which not only produces poor picture quality, but unevenly burns the phosphors on the crt guns. The warning you read was really more of a disclaimer because of worst case situations. Set contrast and brightness below 50 to 60% on most of your viewing and not only will you get a much better picture, but I don't think you will ever experience burn-in. Quality 4:3 sets are the Sony KP61HS30 or the KP53HS30. In the Yahoo Sony HDTV groups, there are 2500 members and thousands of posts and I have yet to hear of anyone having burn in problem due to watching too much of one format or another.Here is a excerpt from a Corning white paper on the life of CRTs with
respect to usage:"CRT life, for all practical purposes, distills down to cathode life and phosphor life. The
cathode life is primarily effected by cathode loading or cathode current density. Specifically,
oxide cathode life is optimized at about .3 A/cm2 due to temperature effects (.. .the cathode life
is enhanced if the cathode operates between 1000 and 1130 degrees K). Phosphor life decreases
as a function of electron bombardment, The amount and rate is unique to each phosphor. The
life of the phosphor is also effected by the tube diameter. The time for the tube brightness to
decay by 50% for a 12” tube operated at 200 micro-amps (.3 A/cm*) may be 18,000 hours,
while a 5” tube operated at the same current would only take 1,500 hours to decay to this 50%
value. The smaller display would, however, operate at twelve times the luminance of the larger
display."
actually it is not Tube Burn it is phospher burn and it can happen very easly.
be a few sets of the type you want. Check Sony. I would recommend, however, that you buy a 16:9 set with a 4:3 stretch feature so that burn in doesn't occur. Some people don't like the stretched picture, but I'm not bothered by it on my Toshiba 65 or 40 inch sets. You'll then have a set that is optimized for widescreen DVDs and/or HDTV, should it ever happen.
I kind of agree with your thinking, but I really can't stand the stretching of the image to fill the screen, and I really do watch alot of 4:3 material (STV, VHS etc.) and since I really don't own any one piece of equipment more then two or three years anyway, bu that time, there will be enough HD availability that the 16:9 will be the only way to go.I guess I could always stick with my 36xbr400 for another year...
Check different brands for the stretch modes they offer. My Panny direct view has a mode called "just" which only stretches the outer quarters of the screen. This leaves characters (who are usually centered in the frame on TV shows, unlike movies) essentially untouched. I watch 4:3 material in this mode all the time and its not bothersome. You will also often find a "zoom" mode, but that will cut informnation off the top and bottom of the image and result in significant reduction in image quality. Every brand is a bit different and individual sets offer options of varying quality. Go look at some sets and see what is acceptable to you.In other words - don't give up on 16:9 just quite yet. These things are long term purchases and if you accept the 4:3 compromise now you might end up regretting it for 8 or 10 years. And in the mean time NOTHING beats seening a widescreen DVD or HD image on a widescreen set.

You might look at an Elite by Pioneer in the theatre wide mode. It breaks the stretch portions to more than just three. it is kinda pricey (53" is $5,400) but the black levels and white levels make for great color.You do get used to the streaching after awhile and as was stated DVD's are great (even the 2.35 DVD's)
Tell mchad. I'm not in the market.joe
mchad,The grey bars are on the screen to minimize burn-in effects.
Most of the 4:3 High-Def RPTVs do the anamorphic unsqueeze, but how much broadcast TV vs. DVDs do you watch?
Me, I watch about 75-85% movies, so 4:3 wasn't a consideration.
Regards,
Unfortunatly, I do watch about 60% 4:3 material, and 40% dvd, so the 4:3 burn in is as big an issue as the annoying grey bars.I read that the (two) DLP RP's out there (Panasonic and Mitsu, $7000, minimum) are immune to burn in, as they don't use crt's, but that's way too much for me...
