Plasma burn in software

When was the last time you were at an airport? If they're not brand-new, I bet there's image persistence or burn-in regardless of the technology. I've seen this first hand with an LCD display recently, so it's not a myth. OK, not everything has burn-in. DLP can't, at least not in the ways we're discussing. More likely, a mirror will stick on or off, causing that pixel to be white or hopefully black. Work at it Can burn-in be permanent? But you've got to work really hard at it.

As in, you have to either be trying to burn an image in, or be forgetful enough to leave a single image on the screen for days. Because you have to be exceptionally careless to cause serious burn-in, plasma companies' warranties don't cover it.

They also won't cover throwing things at the screen, dropping it in the pool, or lighting it on fire. If you're worried about it, be aware that cable news channels are the worst, as are video games that have anything static onscreen like a HUD, or stationary avatar.

Letterboxed movies have the opposite effect, with the black letterboxes remaining dark while the movie image persists. It is much ado about nothing. OK, not nothing , as it's a real thing , it's just not the issue some people make it out to be. Lots more info HDGuru. Got a question for Geoff?

There's also plenty of general questions concerning plasma vs. LCD , particularly those stemming from concerns over the issue of plasma burn-in. In a lot of cases, those concerns are stopping people from buying plasma. It's been noted that permanent plasma image retention is largely a thing of the past. However, in making that statement, does testing take into account usage such as running CNBC for 8 hours a day? I note the latest articles on burn-in are two-years-old. I'm a skeptic and think something's an issue if the manufacturer refuses to warranty against the issue.

Well, Ron, the short answer is yes, burn-in or permanent image retention is largely a thing of the past the key word here is "largely". But the longer answer comes in several parts -- let's call them seven things you should know about plasma burn-in.

Here goes:. What exactly is burn-in? Plasma, like tube TVs and older CRT rear-projection televisions, is a phosphor-based screen technology.

Due to uneven wear on the phosphors, if you let a static image sit on your screen for too long, that image can end up leaving a ghost of itself behind--it appears burned in to the screen. The biggest potential for burn-in occurs when you have a high-contrast image -- such as bright text set against a dark or black background -- because some pixels are turned on to the max while others nearby are completely turned off.

A good example is when you watch aspect video on a widescreen display and have black bars framing the image on either side the pillarbox effect. It's rare to have a brilliant software program coupled with such a good machine.
