Basically, what Lee said.
There was a lot of discussion about this earlier, and I think the upshot is that a $30 cable box couldn't possibly scale video as well as what these $5k TV's do. And As someone pointed out, all LED TV's have to convert their input ("scale") to their native resolution, and on this set they get that right.
Therefore, if you can, select "native" as your output format.
DirecTV has a setting called "format" or "resolution" or something along those lines. As I recall it's on two menus: one sets the allowed output formats and the other selects native; or something like that. When you select native, and 480p is an allowed output, if the show is 480p that's what the "cable box" puts out. "" with 720p, 1080i, 1080p, whatever.
The TV then converts whatever it gets to it's 2180p resolution. And it does a strikingly good job.
There was some discussion about the Directv box looks better if scales 720p to 1080, but our sets are 2160 which is an exact multiple of 720, so I'd expect native is again the best, but I see no differce on the lousy signal that the evil do-ers at FOX put out. And BTW, on Directv box I think/know the output doesn't change until you change the channel. Which makes it even harder to detect a difference.Edited by jjnbos - 2/7/14 at 1:40am
