And you can speed up your PC too!

Windows sets default screen resolution at 32-bit, whereas the maximum resolution which the eye can detect is 16-bit. Set your screen resolution to 16-bit, and you'll see an immediate increase in speed, with no perceptible loss of resolution.

300dpi at 8 inches would be the equivalent of viewing 44dpi at 51.2 inches. You wouldn't want to view a 50 inch widescreen TV at 8 inches would you?

If 300dpi is the max perceptible at 8 inches then at a room viewing distance of, say, 20ft, this rather suggests that 10dpi would be sufficient (or 20dpi at 10ft). Does anyone view 50 inch HD screens from 51.2 inches? It all suggests that under normal viewing conditions High Def has no real advantage over Standard Def*. Maybe time to rush out and buy one of those bargain BV5's!

Makes me feel happier about my CRT Avant.

* other than allowing extremely large screens for viewing from even greater distances

I think processing power and transmittal rates will not allow this to happen for many, many years to come.

A great theory about putting it to rest, but no matter how hard you try, it will almost always be superceded by additional technology or an evolving technology that makes it a little bit better.

Human eye resolution and the ultimate TV

I’ve been reading about the human and from what I can gather at 8 inch viewing distance the best resolution the stationary (non-scanning) naked eye can resolve is 300 dots per inch. If one considers a 50-inch WIDESCREEN (16:9) television its screen is 24.51 inches high and 43.63 inches wide.

If we consider a 50 inch widescreen TV:

In HDTV 1920 x 1080: we get 1920 dots/pixels over 43.63 inches width of screen = 44dpi.

But if we built the ultimate TV that achieves 300dpi we would need 13089 x 7353 panel… equivalent to 96,243417 dots/pixels.

In summary HDTV widescreen = 44 dpi

Ultimate TV = 300dpi

So we need to invent a screen that can squeeze approximately x7 more pixels or dots into that inch compared to a HDTV screen. Now that is something to aim for isn’t it...Hopefully when that’s achieved that will put the whole argument about TV resolution to rest forever. Of course nobody views their TV from 8 inches and there are other parameters such as black/white levels, luminescence, contrast will also need to be worked on…

May be 3d TV using lasers will be up and running by then. would be amazing having 3d people projected into your living room - scary!!!
