Can't display 1080p

[thirsty1258]

Anyone know why I can't get 1080p through my optoma hd20 projector. I have the settings to display in 1080p for hd channels on dtv box and projector. It is displaying in 1080i.

Most I can see if 1080i. Any tips?

Sure, theres very few items that are done in 1080p.

You CAN view a VOD or Cinema movie, one of them is done in 1080p, I don't remember which one though.

Check channels 1000 or 1100, the 1080p stuff will be labeled that way.

Thx so I'm assuming hbo hd is 1080i then?

Yes, all of the channels below 1000 are at most 1080i.

 

[thirsty1258]

Thx for the replies that makes sense now . I was scratching my head. It still looks very clear better than my cox cable did.

A lot of your Games will be done in 1080p .... the majority of actual TV is not done in 1080p, no networks do it at this time.

Games as in RSN sports? No, there aren't any games in 1080p. With the exception of the 3D channels (and specifically listed PPV/VOD) there is absolutely nothing that is broadcast in 1080p. ESPN has just (as in a few months ago) started testing whether it is feasible.

FYI, with sports (especially hockey) given a choice between 720p and 1080i, go with 720p. It's less real estate on the screen but fast action is smoother.

Oh no, I should have clarified more, what I was referring to was the Playstation type games, not the ball games.

Ahh Thx guys. That's why I started to notice because my xbox played in full hd. Either way dtv looks better than my cable on my theater set up.

Going with 720p won't give you any smoother fast action unless the signal is originally in 720p (ESPN, ABC, Fox etc) , and even then it's not certain you will see any difference.

More information to work with on a 720P vs 1080i signal. (looking at it as a full progressive screen, which is what your eye views)

No, only if the original was 720p. If it was a 1080i signal, then when it is converted to 720p there is the same (actually even less) information. The theoretical advantages of 720p for fast motion (and most of the time they are only theoretical) only apply if the signal has been in progressive scan all the way from the source. And of course by converting from 1080i to 720p you lose resolution.

I'm not sure , but we might be saying the same thing, differently.

IF your gonna use a common denominator, 720p is 720p, 1081i is 540p, so there is LESS info to work with to see the progressive scanned frame in the 1080i feed.

 

[thirsty1258]

So its actually clearer to watch 720?

I don't see a difference.

Technically yes (vs. 1080i). There is more information on the screen with 720p. Whether you can see the difference, well, that's a function of your eyes and brain, and how well your TV handles the processing. Personally I can see a difference watching hockey, but everything else not so much. I just keep everything set to 720p though. Give it a try on NHL Network (make sure it's a newer game they're running).

They should both look great.
Alot depends on your set up as well.

To tell you the truth, my old 1080i Mutt brand bought on a Black Friday sale had a more choppy image than my basement's Old Sony SD. That was Comcast and Dish (sorry never subbed to DirecTV) Now my Samsung 1080p gets a better image on 1080i (with Dish) than the previous tv, which is now in my bedroom. With Comcast, which I get locals with, it gets a really nice picture with 720p as well via FOX MLB and NFL games. Basically, I believe the TV has something to do with it as well. But, I'm not at strong with the tech side of things and you guys could blow me out of the water with tech information. I'm just going by what I notice.

Your eyes and ears are the best at measuring technical "specs", IMHO!

Actually, 1080i has more information than 720p. 1080i is 1920x1080 at 30 fps. 720p is 1280x720 at 60 fps.

If you do the math and add up all of the pixels being sent per second, then 1080i is 62.2M pixels per second, whereas 720p is 55.3M pps.

Also 1080i is not equivalent to 540p. There actually are 1080 unique lines of resolution. 720p has only 720 unique lines of resolution. 540p would have 540 lines being sent at 60 frames per second. That would smoother motion than 1080i, but have only half the resolution.

If you are upconverting a signal to 1080p, a native 1080i signal will provide more information than will a native 720p input.
