MASTER BURN-IN THREAD: READ THIS FIRST! (And ask follow-ups here.) - Page 7

I have read most of the replies on this thread and couldn't help wondering if people are messing up the 16:9 and 2.35:1. They are 2 different aspect ratios. 16:9 is really 1.77/1.78:1 and 20:9 is 2.22/2.35:1. They don't make widescreen TVs with 2.35. That is why you see bars on the top and bottom of a 16:9 TV when you watch a 2.35:1 movie. You have to buy an expensive projector to get it to display that image natively.

That is why when you go to a theater they have curtains that move closer for the different aspect ratios.

Just thought it was interesting that some people were referring to 16:9/2.35:1 in the same breath.

Not trying to offend anyone.

I don't think most are missing this. I know fully well the difference between 16:9 and 2.35:1 or 1.85:1. On my widescreen 16:9 Pioneer RPTV in FULL mode, (all information coming from the source is shown), I see the following:

1.85:1 Material
Anamorphic - no bars
Non-Anamorphic - small bars - can be stretched away in ZOOM mode

2.35:1 Material
Anamorphic - small bars - can be stretched away in ZOOM mode
Non-Anamorphic - large bars - when stretched to ZOOM mode the bars are reduced to the size they would be if the picture was Anamorphic (as I understand it, this is how a DVD of this type should be viewed)

I am not convinced all of us with RPTV's are being paranoid. I just got off the phone with the Toshiba customer service rep who told me under no circumstances should I ever allow any bars on my RPTV. He said to always stretch the picture to fill the screen. Which is an interesting statement considering I can't stretch the HD signal I am getting from my local cable company as the signal is broadcast in 4:3 HD, thus not allowing the stretch function on my TV...what good is HD TV and HD cable boxes????

This is crap.

We buy these sets for being able to see our favorite movies in a large format and we are told by manuals and companies to stretch alter or zoom the picture to get rid of bars beause of burn in.

Sounds like a company line designed to protect them against claims by people who don't take the simple steps (outlined in this thread many times) needed to avoid burn-in.

My Toshiba widescreen set is now well into its fifth year. I've watched material with bars (letterbox and side) nearly every day that I've owned it. No burn-in. Of course, I've also had it professionally calibrated three times, and I routinely tweak the settings myself with AVIA. And when I walk away for 10 minutes, I always switch to a display mode that fills the screen.

Be cautious? Always. Be panicky and paranoid? No need.

Michael: Thanks for your wisdom. I do think many of us are spending way too much time worrying about burn. I have not had my set professionally calibrated yet, but will after it gets a few more miles on it. I did calibrate it myself the very second I turned in on using S&V and took it off torch mode.
I agree about the manufacturers trying to cover their butts. You'd think they would design a set to withstand 4:3 issues as most network TV is still broadcast in 4:3 and will be for the next couple of years anyway.

Maybe I will have a martini and chill about the whole thing.
Thanx

I have a question that I have not seen answered here. Are digital sets susceptible to burn in?

I would suspect that DLP based systems would not be, and LCD MIGHT be - the crystals may or may not be subject to degradation based on the amount of HI light they are filtering out.

I am looking to get a rear DLP unit, mainly because I have been hearing stories about the longevity (or lack) of in LCD, and personal taste, I find DLP to be better reproduction overall.

Thought this topic was dead but since it's not quite, here is some good stuff I learned from a member on another forum and it works!
All of my previous posts were regarding stretching while watching cable tv. The channels that carry HD programming here(different from the analog channels) are only HD 16:9 in prime time, for the most part, and then they are 4:3 with bars inbedded on the sides and the fear of burn in.

In order to solve this dilemna, this is the solution I found that works for me.

In the setup menu on your STB, if you are watching a program that won't allow stretching(upconverted signal or whatever), changing the input form 16:9 to 4:3 Pan and Scan, then change the resolution from 1080i to 480p, use component inputs and Bob's your uncle(translated, there you have it) There are other combinations that work as well, this one seems to have the best PQ. Once HD programming resumes you will have to change back to the HD 16:9 setting on the STB.
Good luck all.

Yes, burn-in is a very real!! I bought my Toshiba 42HDX82 just this past spring. After only 8 months of watching mainly 4:3 TV programming (with a contrast setting of 40), I can see distinct faded bars on the sides when I watch in stretch mode...doh!!
