Technical question : 1080p @ 720p TV? Which machine should do the resampling?

[Algernon]

(see signature for hardware)

Ok, I can set my BDP to play "automatic", "1080p", "720p", "direct source" (whatever that is) and something else ...

... now as the TV's resolution is 1366x768, I wonder ...

If I feed the TV any other resolution but 720, it must resample it to 720, right?

So is there any difference in having the BDP set at "auto" or at 720? (In case of the latter, the BDP will resample, right?)

connection is HDMI on both ends ...

final question, if I may:
What's with the "768" points of the TV???? Isn't that actually worse than 720, as the pic will have to be resampled?

Thanks a lot for any assistance

Which one does 1080->720 best, the TV or the player? You have to try both and see which gives the best results with movies and live action.

768? Yes, if the native resolution is 768 the display will have to do 720->768.
Some displays have a 1:1 pixel mapping setting. If yours has it you could watch 720 as 720. The image would be a little smaller (you'd see narrow black borders on all sides). But depending on the scalers quality and your seating distance, scaled 768 might look fine/equivalent to 720 straight.

Thanks for the reply!

Yes, I already tried both - can't really see much of a difference ...

... I wonder though, why they build a 768 TV in the first place?

at 4:3, the TV stretches horizontally, but not vertically, unless I make it fill the entire screen, which cuts off parts of the pic

[Deciazulado]

You mean that with 4:3 shaped DVDs you can only see them in strectch mode? (4:3 stretched to 16:9) (You have a 16:9 tv, no? Haven't checked your tv's specs)

When you say that when it fills the screen, and cuts off part of the pic, you mean it chops up a lot of the sides?, or just a little bit of the top and bottom (and a little of the sides too)? If that, (just a little), it's just overscan that many sets have.

About your seating distance, I think you could sit at 1.5 meters

768. well 768 is a computer height resolution (768 x 1024, 4:3)
At 16:9, 768 x 1366 is exactly half the pixels of 1080 x 1920, while 720 x 1280 is less than half.

no, I can switch modes on the TV, of course ... but with some DVDs (e.g. the "Dallas" edition, the 4:3 mode isn't working correctly ... I got the black bars at the side, but - no matter which aspect ratio mode I chose (there are 7 on the TV) the ratio is not quite correct - it seems "slightly" strechted vertically ... UNLESS I choose 576p on the BDP as input signal ... "automatic" doesn't work right with those DVDs ... well, that's not a big deal ...

I am more concerned about loss of image quality due to streching from 720->768 ... (not that I would know a difference, seen I have never seen it UNstretched, lol!) ...

unfortunately the TV has no 1:1 pixel map ... well, the good side is that I got a pic which is a little bigger now at 720p ... as you observed, I shouldn't sit farther than 1.5m ... oh dear ... ... well, no use crying about it, at best I could put a 37" in that "TV-space" instead of the 32" ... would enlarge the distance to 1.8m or so ... not much of a difference ...

thanks for the reply!
