I have a Blu Ray player. It looks amazing at 720, and I never have problems with it. It is connected via an HDMI interface.
Pretty much my point. From that distance away, you wouldn't be able to really tell any difference between 720P and 1080P. I wonder how many people have bought TVs based on looking at them up close in the store, only to get home and realize that they can't see much of a difference from their old 720P TV when they start looking at it from a normal viewing distance.

Bluray discs are 1080, aren't they? Why is it that you can watch them on a 720 TV screen?

Also some channels are 1080, can you watch them on a 720 TV?

They are scaled down to fit the resolution.

True. By that same token, DVDs are 480p. The signal is therefore scaled to fit the resolution of a 720 or 1080 screen. Some players "up-convert" the signal from the DVD to make it seem like it's being displayed in a higher resolution. I am not completely convinced that this trick makes a major difference, though.

A good scaler isn't going to make your DVD look like a Blu ray disc becsue it can't add detail. What it can do is preserve contrasting line of color. A typical method for scaling is bicubic but contrasting edges will become blurred and overall everything becomes soft looking. What a good scaler does is looks for those contrasting edges and will keep them sharp.

This example is photography software scaling an image but the tech is the same. The one on the left uses Genuine Fractals for scaling and the one on the right is bicubic.

From how many feet away? If you're sitting within 5 feet of a 46" TV (or higher) then yes, you're probably going to see a difference.

honestly this seems like something I was asking 3-5 years ago. These days just buy the 1080.

Lots of people don't even know the difference between the SD and HD versions of their cable channels though, so in that case it's not going to make a difference. whatever makes them feel good though.

This is how I approach the argument: If you already have a perfectly good 720P TV that was made in the last four years, and it's adequate in size and viewing distance of your room, then it would be foolish to upgrade to a newer 1080P. If, however, you are in need of a new TV, because your old one is failing, then yes, you would be foolish to try and find a 720P TV when there are plenty of great deals on a 1080P. I think that is where the argument lies. When my 720P TVs fail, I'll replace them with 1080Ps, but right now, there's no need.

We have it about 10-12' from the seating areas.
Sony is releasing it's 4K televisions starting at 55". It is debatable if you would actually want to spend $5000 for a 4K resolution at 55", but the 65" are $7500 and the 84" are $20,000.

At 84" even 1080p starts looking a little grainy.

But if you have $20K to spend on a television, that's God's way of telling you that you have too much money.
