Image retention/burn in using plasma as computer monitor

post #1 of 4
Thread Starter 
I'm sick and tired of my 32" Sony Trinitron (darn thing just won't die...15 years old). I am ready to jump on the flat panel bandwagon and am really torn about the LCD vs Plasma issue.

My room does have some light coming in but it's from a window that is covered by a flat roof over the back porch...and on top of that 95% of my TV watching is at night...so I'm not worried about reflected light being an issue.

I'm looking at the Samsung PN58A550. We really feel 58" is as small as we want to go which definitely lends itself to plasma to save some $$$. (Do they make many LCDs over 52"...only see two 65" at Bestbuy.com)

My real concern about all this is that I'm going to put in a Windows Media PC in the living room and the plasma will be used as the monitor. Now I won't be using the plasma for a computer all that often...maybe a few hours a week at the most. But when I'm using it I don't want to be worrying for those few hours that I'm damaging the TV. There are some obvious things I'll do like setting a screen saver at 10 minutes or so. But what if I'm using a program (any program...but take Google Earth as an example) for an hour or more...while I may be zooming around the world for most of the screen...the top bar will stay a consistent image (as it would using any program typically). That is where I'm worried about image retention/burn in.

I know this use to be more of a problem (as posts here from 2005 state) but it's my understanding that plasmas have gotten better about this.

I know this is a debatable subject but I'd love to hear from anyone using a plasma with a computer and hear how its working out for them.

Thanks

I advise that you get an LCD panel if you plan to use it for a computer as you describe.

Keep the contrast no more than halfway for TV and movie viewing and no more than a third for computing and gaming. You may do your calibrations around the 1/2 contrast and don't bother calibrating for the 1/3 if the TV does not have presets to remember both sets of settings.

This way you won't have to worry about image retention.

It is heat that degenerates the phosphors and the glue that holds them on. High excitation, including vivid colors that don't look all that dazzling, generates heat faster than the glass can dissipate the heat.

Image Retention and Burn-In are always concerns, but much less with today's top-tiers.

I always recomend LCD's for new buyers. Plasmas are much heavier (glass panel) and do have some maintanance issues. Most importantly, the quality difference between a high-end LCD and a high-end Plasma is often too subtle for new users to appreciate.

But if you do decide to get a Plasma, you should "break-in" your set. Turn down brightness and contrast to 50% and leave it on for about 100-150 hours. This "matures" the phosphors so they are less likely to "burn"

Here is a step-by-step explanation on "break-in"
