I just wanted to start a thread with what resolution people have their HR20 set at and what there TV's native resolution is. I'll start it out so everyone knows what I mean. If you like you can give reasons/explanations why you use said settings for your setup.

Vizio 42" LCD GV42L - Native resolution = 768p

HR20 set to output 720p only.

Native OFF

My reason for these settings is: There is no reason to have the HR20 set to display anything that the TV will then convert to 720p anyways. EG. If i set the HR20 to display everything at 1080i, the HR will take a 720p signal, convert it to 1080i, only to have the TV convert it back to 720p to be displayed on my TV.

There you go. Let's see some setups. Does anyone feel they get better PQ by having the HR20 set to 1080i? I don't see any difference myself.

EDIT: After some extensive testing with 1080i sources material, I have found that letting my TV down convert 1080i signals the picture looked better to my eyes. So I have since set my HR20 to output 720p and 1080i. The 720p channels do follow my initial findings of showing more noise when converted to 1080i and then to 768p by my TV. Just figured I'd update this post with my findings.

In my case I have a Hitachi 55 inch plasma, 720p or 1080i, so should I set it to 720p or 1080i? I also have my Yamaha receiver set to 1080i, which one should I let to the upconverting? I am guessing I am doing it on too many pieces of equipment.
(I just got the HR20, had the HR10, which was always set to 1080i):nono2: :eek2:

PS: I turned native off as it was making the menus look blurry and slowing them down...
These questions are the point of this thread. :)

I'm not quite understanding what you are saying. Is your plasma native displaying 720p or 1080i? If it is normally 720p then I would set the HR20 to only display 720p. I do know that some of the newer Hitachi plasmas display a native res. of 1080i so I would check on that and then pick one or the other. In my opinion it makes no sense to be converting a feed 2 or more times before displaying it. It can only make it worse at that point.

Well it's confusing cause it does both, as I was told by Hitachi, 1080i is the same as 720p, 1080i is interlaced, 720p is the native, so I am thinking to go with 720p. Just not quite sure....Now if it was 1080p that would be a different story... but 1080i is not any different than 720p, so I am thinking it makes no difference to the setting, but that's why I am asking cause I am not sure....
Well hitachi told you something incorrect. 720p is NOT the same as 1080i at all. They are two completely different resolutions. It is not just the p and i that make them different. My TV will accept 720p and 1080i but in converts the 1080i to 720p before displaying it. This makes my TV's native res. 720p. I suspect that your Hitachi does the same thing. What's the model number of your plasma? I'll check it out online and tell your for sure whether its native resolution is 1080i or 720p.

Not that it matters, but the native resolution for your TV is 1366x768.

(source)

But your reasons for forcing 720p are still valid: no matter how you stack it, there's some sort of scaling going on. With 720p, less... with 1080i- more........
BTW: I have two other HD displays that all have native off due to the fact that they are poor at, or unable to scale 720p correctly: an EDTV [482x854]DLP projector and a 1080i (960ix1440 actually, I measured it with an HD signal generator) Rear-projection CRT. With all these 'non-standard' native resolutions, I definitely need an outboard scaler! Just haven't been able to convince the wife yet.
I just wanted to say that what you are saying is all completely correct. My set as well as jwren's plasma are both technically 768p.

Now my TV I know to have Faroudja De-interlacer which from what I understand is a very good one. But with my eyes I see no difference between letting the TV or the HR20 do the conversion on my set. So I just leave it on 720p and I'm a happy guy. I just finished watching the Louisville vs Rutgers game and it just looks astounding. I can't even imagine it looking any better. That being said, I was not sure what to do when I first got my TV and had the hr20 installed, so I figured others would have the same question that I did.

jwren, your tv is native 720p (768p technically but 720p by industry standards) so I would recommend leaving the hr20 on 720p. Less conversion means better picture quality. Hope this helps with your grainy pq issue you posted in your other thread.

Are those TV's any good? I know they are cheap but how is the picture quality?

And I am talking Vizio in general, not that particular model.
Blitz 68, I can only speak for this model as I have only used this one. I will tell you that the picture quality is superb. I cannot state it any better than that. Can you get better PQ on and LCD for this price? Nope. The picture in my opinion, is right on par with the Samsungs and Sonys that cost many hundreds more. SD PQ is great too. Far better than even my father's Panny plasma that cost $1000 more than I paid. You cannot find a better value for this kind of PQ in an LCD right now. If you look online at some professional reviews even they are astounded by the picture quality of the set I have. Now thats saying something.
