Hello, new here. Anyway, I have a few questions about tvs. I am fixin to graduate from college in 2 weks and am planning on buying a big screen when I get an apartment. I also plan on playing video games and watching dvds fairly often. I have heard that some tvs will "burn" an image and others would be ok. I talkd to a guy at Circuit City and he said an LCD or DLP is pretty good. Does anyone here know what to get or have any tips?
Thanks

Welcome to TV Forum. Not really about TVs, more about what's between the programmes on them, but the thread below might help.

Thought this was about the beeb's big screens around the country, but anyway.

Don't all LCD/Plasma screens suffer from burn-in? Or have they found a way to reduce the effect, especially now as the uptake of screens is probably higher now than it ever has been?

Video games and their static graphics, and channel DOGs cause burn-in, even on CRT. (an episode of Bad Influence showed us a studio CRT with the ghostly image of a VT clock stuck on it)

LCD displays are immune from 'screen burn' in the common sense, but constant static images can cause 'stuck pixels' which produces a ghosting effect on that part of the screen.

I remember that episode of Bad Influence. They showed the monitor as part of a feature on screensavers (of those were the days when almost nobody had one - ironically screensavers only became commonly place when advances in technology had removed the need for them in all but the most extreme cases). This programme aired in the early 90's, the monitor probably dated from the early 80's, and was in all likelihood used exclusively to display VT countdown clocks. I wouldn't say it's typical of the kind of screen burn you can expect from a modern CRT (the only modern CRTs I've seen suffering from screen burn are on the computers at work, and that's only because they display the same screen 24/7.

In a nutshell

DLP, LCD = No screen burn

some CRT's and Plasma's = Prone to screen burn

oh talking of that, I thought LCDs didn't do screen burn, but I was playing with the tills at work, and when you go to reports the main background goes black and you can see the WHSmith banner at the top, burned in.

Now they've been displaying the main till screen non-stop since last June, despite my protests that we should turn the tills off overnight. Head Office know best though.

I have never heard of a CRT in a domestic setting suffer from screenburn. We did have one in the old analogue TV Continuity area that had at least two BBC ONE clocks burnt into it, and a few which now have BBC ONE or TWO logos burnt into the corners. Unless you have a static image on it for (at the very least) MONTHS, you won't get screenburn.

There's a McDonalds near us that has a CRT TV that has suffered from it, as it now has the BBC logo from Ceefax permanently burned onto the screen, due to the fact the Travel page had been on for several years. Confused

I knew TV's were prone to Screen burn, though I'm glad LCD's are rather immune (though not in the clear) as I just paid £330 for a new LCD TV the other week.

Yes, I remember them; the ones used a lot for trails with '1' and '2' in the corner - still displaying the old logos many years after they were discontinued.

It's also common with monitors that are connected to the 'character' output of a VT machine, the timecode window burns into the screen. not normally noticable until you use it for something else or switch the timecode display off

Talking of screen burn, take a look at this which I noticed today:

UTV only ever had their logo on the plasmas but they have now started using them for story titles rather than a side bar. That's why it has only now become noticeable!

Ewww, that is nasty, I heard the plasmas in the BBC Reception are badly burnt by the their (BBC) DOG. Surprised

(Thanks for the pics)
