Question about Pixels, Resolution, and Size for TVs

Cyberock · 02-05-08, 06:57 PM

Probably a dumb question but I've always kind of wondered about this. I always hear that resolutions have a certain amount of pixels. Does that mean as the TV gets bigger, the pixles become bigger or is there an increase number of pixels? In other words, does a 32" 720p LCD have the same number of pixels as a 50" 720p LCD?

Yes. Welcome to the screen door.

For reference, "screen door" refers to the space between pixels, which can be visible at certain distances.

The answer is yes, the pixels get physically larger to fit the larger screen. And hopefully larger enough to not have a screen door problem at normal distances. A front projector has really tiny pixels to fit all of them into less than an inch wide panel.

This reminded me of an ad I saw once for the Game Boy Advance. Nintendo claimed it was "sharper" than an HDTV because it had more pixels per square inch.
