LCD and plasma burn-in advice

by Matt Burns, posted Aug 23rd 2007 at 7:22PM

Image retention, the kids call it "burn-in" on the street, is something every flat-panel has to deal with. HD Guru dug up a case involving not a plasma but, gasp, an LCD. It seems like logos were "burned" into the the right of the screen. The issue is something that rarely pops up -- even more rare on an LCD -- but when it does, we're sure most owners shave a year or two off their life as their heart skips a beat. There is no reason to fear that your pricey, little baby will always have that Sony DVD logo burnt in, as most burn-in can be easily eliminated. Follow the jump for some DIY tips on prevention and elimination.

High-powered lasers will allow burning dual-layer Blu-ray at 10x

Lasers burn CDs! - CC images from http://commons.wikimedia.org/wiki/Image:CD_autolev_crop.jpg and http://commons.wikimedia.org/wiki/Image:Helium-Neon_Laser.jpgOnce the realm of mighty giants with huge pocketbooks, burning a dual-layer Blu-ray (or HD DVD) disc might be yours at ten times normal speed starting in 2008, when Japanese firm Nichia Corp. will start production on a higher-powered laser diode for use in recorders. The diode emits pulsed light at a higher output than current models, and is stable enough for 1,000 hours of operation, which we estimate should net you around 5,000 two-hour burns... of data, of course! It will also allow for 2x burning of up to four layers. We're still waiting for word on how fast it will burn those ten-layered discs.

RITEK rolling out HD DVD-Rs next month

by Richard Lawler, posted Jun 19th 2006 at 7:03PM

HD DVD-Rs are on the way, with Maxell/Hitachi and Mitsubishi/Verbatim announcing shipments to Japan in July, and September in the US, now Advanced Media, better known as RITEK or RIDATA, has announced they will ship single-layer HD DVD-Rs to the US in late July. Other than the 15GB discs next month, they will release dual-layer 30GB HD DVD-Rs and single-layer HD DVD-RWs sometime in the fourth quarter.

We're still left guessing as to the burning speed supported by the discs as that is not mentioned in the press release. There is also no specific price mentioned, but we can expect HD DVD recorders to become available around the same time as the media.

Burn-in on plasma TVs

The burn-in issue on plasmas is something that just won't go away. Manufactures have tried hard to prevent it as much as possible but still, it is a side effect of the technology. There is a group of consumers down under (in Australia) that purchased plasmas before the holiday's and left them on for hours days causing the stations logos to be burned into the screen.

Yes, we know plasma this and plasma that, but there are easy things to prevent burn-in.
  1. Burn-in is most likely when the TV is the brightest making the first 24-36 hours of life critical. Even some manufacture set-up screens can cause nasty image retention. (not burn-in but rather, ghosting for a short period of time.)
  2. Turn down the brightness past 50%. Plus, you will get a lot deeper picture. 
  3. Avoid static images. This does not mean the ESPN banner or ABC logo but rather the Window's Start Bar or OS X's Dock. Use the plasma as a TV because you WILL get burn-in if used as a monitor. If you pause the Xbox, turn of the TV.
Believe it or not, plasmas are not the only type of display technology that can suffer from burn-in. CRTs have always had this problem, (think old school screensavers) but so have LCDs. WHAT?!? No! But yes, LCDs can burn-in. The best proof we can give you is Apple's guide to removing burn-in. It is rare and requires the image to be static longer, but it can happen.

Do not be afraid to buy a plasma because of the chance of burn-in. There are tools and techniques to remove burn-in but if you plan on using the plasma as a TV rather then a computer monitor, then you should never ever experience it.
