In case anyone has an LCD monitor they're playing with this site has some pretty cool info --

may have or develop "stuck" pixels not pixel-based no problem


um... CRTs definitely use pixels and they still get stuck/dead pixels just much less likely than LCDs altho LCD quality control is getting much better and approaching CRTs

?? what you are talking about? CRT's have pixels? Sure if you count each grain of phosphor as a pixel. graphics cards certainly represent images in terms of pixels but they do not translate to actual physically unique units on the screen like LCD's do. If you literally have a stuck pixel as in 1/1024th of a 1024-pixel-wide image is always missing then you have a problem with your card not the actual cathode ray tube. Commence counterarguement . . . ;-)

Exhaustive research has shown that the Nintendo Entertainment System does not have per pixel collision detection. Rather it is a function dependent on two variables: whether or not the player is balls-to-the-wall and if the player "don't even care".

Last post from the ATL for a while. Catch y'all on the flip side.

Mike my 8 year old gateway CRT would beg to differ with you. and go put your nose against the screen of the nearest CRT tv and come back and tell me CRTs dont have pixels

I agree that pixels appear but they are created in a manner wholey different from LCD's. Each one of the three colors in each pixel is created by a physically separate device whereas in a CRT subpixels are the smallest unit of a picture are created by a mask within the monitor to break up an otherwise continuous beam and 1 pixel as intended by the computer can be made up of one or several subpixels. The pixels that you see on a tv are the bright spots created by gaps in the mask and disappear (except for the individual full-screen continuous vertical strips of phosphor that react differently to electron impact and make colors) when the tv is off. A dead subpixel therefore doesn't come from the failure or burnout of an individual diode but either from magnetization or obstruction of a mask hole (dust that got in there during production or something?) or if something bouncing around inside scraped a little chunk of phosphor off the inside of the glass that makes up the screen. I'm not sure if we disagree at this point . . . I guess I'm just pointing out that monitor failure doesn't really happen in a discrete pixel-wise fashion but in a more continuous blob-like fashion. Iii dont really know what that means. but i'm trying. :-D

on a non-technical note i am very excited that the blue pixel dead center on my 19" lcd that became stuck shortly after purchase has recently become unstuck
