Probably a dumb question but

Even with a good crt and graphics card, your eyes are still being subjected to impulses of light as the beam scans over the screen. You don't see the spikes in intensity because your eye integrated the brightness over each frame. With lcds, when a pixel is on, its on with constant even light.

But there's also a speed that's too fast for the eye to adjust to. Most people are happy with 60-75Hz. I need 85Hz, and some very small percentage of people need even more than that.

85 Hz and a matrox card at home is lovely. 85 Hz on this intel 865 builtin pos is not as nice but ok. Never met an LCD that I liked (except the 17" screen on my friend's powerbook, and perhaps the sw1600 silicon graphics that another friend had)

Samsung and other companies should start seriously thinking of making DLP based screens, they are bright and saturation is amazing.

You cannot make flat DLP screens, only front projection (with all the problems fp has). DLPs are digital mirror devices, which, as the name implies, reflect light. They are small, and they need room in front of them to be able to project a decent-sized image, and they cannot be backlit, thus you have the standard front projection layout.

There are quite a few rear projection DLP TVs on the market in addition to the normal DLP portable projectors for use on a wall screen.

Using a screen saver solves it. Now it's just a case of finding out how long the time period needed is.
Like the good old days with crt's this is.

Those burn-in issues are rather seldom and normally model specific. According to the german c't this is caused by inproper electric circuitry controlling the cells.

With modell specific I meant that the whole model series suffers from this (not only an individual one), that's sad, but that does *not* mean other models of the same manufacturer have to suffer from the same.

However, if you get informed a bit about your desired model (I would recommend Eizo ;-)), you're on the safe side!

PS: 2 tips:
-if your lcd displays weather infos all day long & you don't have any burn-in now (just some afterghosting), it's most likely you won't get this problem, at least that's what I think.

-if you get a burn-in, running a screen saver may help to get rid of it.
