Burn-In

Archived from groups: alt.tv.tech.hdtv (More info?)

Hello,

I just recently purchased an HDTV (Mitsubishi 55613) and like watching
standard TV in the 4:3 mode (narrow). On the left and right there are
gray borders. Should I be concerned about those borders and possible
burn-in?

I have heard that using gaming consoles on the TV could cause burn-in,
so I was curious about the narrow mode as well.

Thanks.

The gray color is designed to lower the rate with which burn-in will
occur. Burn-in is a problem for all CRT-based sets (plasma as well). For
a CRT is just means the phosphors are wearing unevenly. Gray is a
neutral color and is designed to burn-in at a rate faster than black
would and a rate slower than white would. Hopefully at the same rate as
the rest of the screen. But it can't be perfect.

You can slow the burn-in by calibrating the set (user calibration is
fine using DVE or Avia), keeping your really widescreen 2.35:1 movies
and 4:3 programming to a minimum (<20%) unless you are using
stretch/zoom modes.

I have an 8 year old Pioneer RPTV and I see no burn-in even after
watching a lot of widescreen movies on DVD.

I would say calibration is the first item on your To-Do list.

Why not screen savers for HDTV's? The side bars could have constantly
changing images. If this is annoying, you could cover the bars with blinds.

OK. How about moving the picture around the screen at a pace
slow enough that it wouldn't be noticable. Say up one scan line per 15
seconds to the top of the screen then back down to the bottom at the
same rate? It wouldn't eliminate burn in completely, but it would slow
it down.
