Why is it TV pictures, even SD ones don't have aliasing problems?

Wouldn't changing the way computer images are made have a bigger payoff than upping the Res every few years?

Old tube TVs running at 640x480 with interlace (aka 640x240 resolution) don't look pixelly because they're so incredibly blurry. If you connect a PC to one of these TVs and try to read text, you'll find you have to blow the text up really huge and even then it's fuzzy.

Another solution is for everyone to have bad vision and not wear glasses. ^^

My understanding of a retina display is that pixel density is so high that a human eye can no longer see individual pixels. Can someone calculate what resolution would a 24" screen have with a PPI of 320?

the PPI is irrelevant without considering the view distance.

I love the idea of "retina display" and would like to see similar technology hit the desktop.
Higher PPI is definitely a plus, just like more cpu power, mem bandwidth, or shader units.
However, AA still has it's place and won't be negated (completely different things).

That is one reason.

The second has to do with the content. Recording the real world (not infinite resolution but individual atoms/photons are very very plentiful) with limited resolution cameras, and as such pixels come pre blended with their surrounding in just the correct amount which creates the same optical illusion that AA does. In fact you could say it has perfect AA.

If you take a real picture/scanned image and zoom into the pixel level (you can do that with photoshop) you will see it for yourself.

And cartoons... well if they are digitally rendered then they are antialiased.

Sigh...I remember when I first "high speed" internet at my house. The porn, uh, I mean, "work-related high bandwidth photos" loaded so much faster...ah, the memories.

Seriously, we've been stuck at 2560x1600 for far too long. Let's at least get some 2k monitors out there!

It's not a "retina display", but you can do that now for ~$30K USD. EIZO DuraVision FDH3601 4096x2160...
