Pardon my ignorance, but I've been wondering why burn-in is such a concern with RPTVs, when it's not an issue with direct-view TVs (and computer monitors, etc). Could someone explain this, or point me to an explanation? Thanks.
Exactly. This is precisely why there are "screen savers" for your PC. If you were to leave the monitor on at your desk when you went home for the night, eventually you'd see slight burn in an uneven wear.[/QUOTE}
I've only seen burn-in on machines like ATMs, where they run 24/7 with the same static image for the majority of that time. I haven't seen burn-in on a TV or computer monitor in the past decade, maybe. My understanding is that screen savers were no longer necessary at least five years ago (because of both higher quality monitors and auto shut-off features). Likewise, most TVs (in my experience) are only on a few hours a day, much less 24/7 with static images.
I guess I'd be surprised if burn-in was a problem even on floor model direct views (assuming running demo material). But I can see how the RPTVs might suffer problems more quickly.
So, has anyone seen burn-in on direct views? Is that problem pretty much extinct given normal usage?
Make that VERY eventually. It is difficult to burn in a VGA monitor nowadays. I've seen it once. This was on a PC that was left on with the NT login box displayed roughly 22 hours out of the day at high brightness levels. After about a year of this, I could see a very slight ghost of the NT login box with the monitor turned off. It wasn't visible while using it for other tasks.quote:eventually you'd see slight burn in an uneven wear.
