is 1080p Marketing Hype?

And here is a calculator for figuring out the optimal size and distance:

They list progressive on the image because it is the best quality. For interlaced, although distance can effect this as well, it is a side effect of the distance. If you view an interlaced image far away, it is still interleced, just harder to tell. But the image is still 720 or 1080 so you will be missing details if you are too far away.

No hype about interlaced and progressive there either. The viewing distance and size determines the best resolution, not interlacing.

All linear graphs are theoretical, and not experimental values..

They are rough estimates based on approximately 20/20 vision, so some people will appreciate 1080p further away than that, others may not.

I have 20/25 vision, 15/15 with glasses. I find 1080p very much appreciable over 720p on a 32" LCD at 6ft.

The fact remains that viewing distance and screen size best determine desired resolution, NOT some line around 37" that makes 1080p necessary.

I have tested that "Viewing Distance When Resolution Becomes Important" chart using my own TV and I think it's flawed. I have a 34" 1080i CRT and a 9 foot viewing distance. That puts me pretty squarely on the "Full benefit of 480p" line. But I can still see a big improvement when looking at 720p or 1080i. My eyes aren't quite 20/20 anymore. So I'm thinking this problem is more complex than the math in this chart suggests. Can anyone else confirm this?

Yes. As posted earlier, I sit over 10 feet away from my 37" 1080p LCD. That means I should barely begin to appreciate 720p. However, not only does a 720p broadcast completely annihilate SDTV and upconverted DVDs, but there is a clear improvement in 1080p over 1080i whenever the picture is in motion.

That graph has no significant accuracy in my personal situation. The fact that my vision is still perfect may have something to do with it, but nevertheless, I have to respectfully disagree with the assertions that graph makes.

Is 1440p going to come out soon?!?!?! Man, I already feel behind with my 1080p TV....

You wasted your money..... you should have saved..... everyone is going to laugh at you when they see you're only running a 1080p set

I don't think our eyesight warrants much more resolution than 1080p (in 'most' sizes) I think Color levels will be improved... but 1080p will become, and remain standard for years to come.

Maybe I'm not thinking this through all of the way, but my understanding is the chart above is in reference to display resolution (meaning ED/480 vs 768p/1080i vs 1080p), not the signals being fed into them. So if you fed the same 1080p signal into a 40" ED set, you wouldn't start noticing an improvement using a 768p set until around 12' or not until you were closer than 7.5' for a 1080p set (give or take based on your eyesight, and assuming the sets were identical except for resolution).

Of course SD (480i) programming will look worse than 1080p at just about any resonable viewing distance, but that's not what the chart is trying to present.

Does that make sense? Be gentle....
