Default HD-A2: 720p or 1080i

Now I know you should set the A2 to the native resolution of your TV but I'm in a bit of a gray area. My LCD TV has a native resolution of 1360 x 768. Resolution wise its closer to 720p, but I am wondering what are the recommendations to get the best overall picture quality (both smoothness and sharpness wise)? Or should I just switch it for different movies? As in set it for 720p for fast paced movies like the Bourne Supremacy, and 1080i for movies like Batman Begins that are just visually sharp?

I have mine set to 1080i, but I have found it really is a personal decision.

Just gotta test both settings and see which one looks better! Different TVs (even with the same rez) perform differently. My 32" and 42" tvs (same rez as yours) look better with 1080i, but my 23" tv (also same rez) looks better with 720P.

I don't think there is much of a difference to justify changing the setting. Either one in my opinion looks great because its an HDTV.

From what I understand, if your native resolution is 720p (or 1080p) as in your case, by setting it to 720p you are allowing the player to do the processing, by setting it to 1080i you are allowing the TV to do the processing. So, depending on which of the two has a better video processor is the one you want to choose...which makes it your personal preference. From what I understand, the first generation models and the A2 as well as the A20 do not perform all that well in 720p when comparing to 1080i. I have both an A1 and an XA2 and because of the Reon-VX HQV chip in the XA2 I am very happy with having my player set at 720p. My HDTV handles the processing fairly well, so, when using the A1, 720P and 1080i were pretty much a wash for me.

Default Kind of a cross post new firmware 1080p/f24

(I have a Toshiba HD-A20 + Sam's Club Toshiba 42HP16 Plasma rated at 1080i)

Basic questions:
1 - Is it better to set the HD-A20 to its highest output setting and allow the TV to down-convert to its highest display setting?
>> In my case HD-A20 to the newer setting of 1080p/f24 and allow the TV to down-convert to 1080i <<

2 - Could you damage the player or TV by not matching the output of the player to the input of the TV?

I can only compare to photo editing on my computer... it is always better to start with a higher number of pixels and down-convert then it is to start with a lower image and try to up-convert.

Match the player's output to the resolution of the tv. In your case set the output to 1080i. By setting it to 1080p, you will end up with a black screen.

Funny... I just got done watching two epsiods of 'HEROES' and with my HD-A20 set to 1080p/f24 and I did not have a black screen?? but I am connected HDMI and somebody else says that the HDMI talks back to the player and resets the out-put the max screen setting so it does not matter if I set the player at a higher setting.

Forgot HDMI sends all that information when it does its handshake.

I have a 50" Panasonic 720p plasma. When I set my A2 to 720p, I notice that the resolution is markedly worse. The best way to tell is to look at small text, such as the numbers that appear on the time bar while fast-forwarding. On 720p, the text is jagged and deformed. When I set the resolution to 1080i, the text is crystal clear.

I think every TV will react differently, and you need to play around with settings to get the best picture.
