My TV is a 1080p.
Do I set Native to ON or OFF?
:welcome_s to DBSTalk
The highest the HR20 will output is 1080i not 1080p. You can use native ON or native OFF. It all depends on what looks the best to you. If you have native ON with all of the resolutions selected the HR20 will output the video at whatever resolution the program is actually in. If you have native OFF the HR20 will output the video at whatever resolution you have it set to and the TV will deal with the scaling. I use native ON because I think it looks better.
The fact that your TV can support 1080p makes no difference. Set Native ON if you want to pass through the broadcasts original resolution (480i, 720p, 1080i) to your TV and let your TV upconvert it to 1080p. Set Native OFF if you want the HR20 to upconvert everything to the output resolution you specific.
What ever looks best too you
Here's a thread that may help answer your questions...
And, of course, :welcome_s to the forum. Lots of great people and tons of information here, and no such thing as stupid questions. It took us all a while to get our heads around these newfangled electronic contraptions.
with a 1080p set I would set native to on with all resolutions checked and let the set do all the scaling. This eliminates double scaling that will occur with a 1080p set: 480i>1080i>1080p, 720p>1080i>1080p. This assumes that you set supports 4801 over HDMI or are using component.
The User Guide has it ass-backwards!
If you turn on Native mode, the receiver will automatically adjust resolution to match the resolution of individual TV programs as they are tuned.
In Native mode, the receiver automatically adjusts resolutions to match the resolution of individual TV programs as they are tuned.
It's a personal preference, but with my 1080p I leave native off and set the HR-20 to 720p. This way I have a progressive signal which seems to consistently look good across most programs/
Depending on your TV's processor it may be able to reconstruct a 1080p/24 signal that's been broadcast as 1080i/60. So if you set the HR20 to output 720P you could miss out on a 1080p quality signal.
For those who've never heard of this before, consider that when a 1080p film source is converted to 1080i they interlace the progressive frames in a specific pattern. If the TV de-interlaces these frames in the exact reverse pattern you end up with original 1080P/24 signal. No scaling needs be performed. This only works with 1080p/24 <-> 1080i/60. Alas not all TV's do this correctly.
I go with native on my 720P TV with all resolutions enabled. I'd recommend starting there and if you're not happy with the channel changing delays that native introduces you can always fiddle with it.
Another advantage of native is that some TV's will automatically adjust the zoom-setting depending on the format (ex: switch to WIDE mode when a 480i signal is present).
IMHO, one of the key advantages of native mode. My TV does a far superior job of creating a 4:3 viewing environment compared to the HR20's pillarbox mode.
For this to work, the HR20 format must be set to STRETCH mode. This doesn't mean that the HR20 will actually stretch anything, just that it won't append any pillars, or do any cropping.
If your TV is set to its 16:9 mode, the 4:3 pic will be stretched, but if it's set to a 4:3 (pillar or some kind of panorama) mode, it will look correct.
As JonW said, most TV's remember their last format setting per resolution. For me, that means 16:9 (often called "full" or something like it) for 720p, and 1080i, and 4:3 (often called "pillar") for 480p. I have 480i disabled, as I prefer to let the HR20 de-interlace the SD signal. But that's for another thread.
