I prefer 1080i. It just looks sharper to me. Plus, my A/V receiver does a pretty good job of de-interlacing it.

That's not how interlaced video is displayed. If you are in a video editing program and have no deinterlacing applied, then yes, it will look like that.

This is fine for video, because 4:2:2 is still better than 4:2:0, which is how ALL video that consumers see is sampled. It simply makes colored text against black backgrounds look like crap, which is why using TVs for monitors is a giant fail.

? Aspect ratio has nothing to do with this...

ramicio, I always wondered about this on PC's connected to most 'very high end' Samsung LED TV's through HDMI...

The text would be unreadable and one way to get it better would be to turn the sharpness all the way down...

I do have a 42" LCD 1080p TV that I use, through VGA that still looks almost perfect (and this was one of the first 1080p TV's you could buy)

What is happening is you're basically applying blurring to that chroma channel by turning down the sharpness. There's nothing to do to VGA. It is a pure RGB signal, so there is no chroma channel to subsample. Any imperfections in the picture is because it's an analog signal and there is some bleeding going on. Chroma subsampling mainly looks so bad because everything that renders video uses nearest neighbor for sizing back up the chroma channel. You can use different resizing algorithms to somewhat band-aid the problem.

Well, sadly broadcast technology is still stuck in the stone age and the only improvement has been spotty changes to h.264 over MPEG-2.

outch!from all the info here i have seen!i agree!we re still stuck in the past!cause after all the thread here nobody really knows!and there are so many different manipulation like chroma subsampling etc!and he just mentionned that lowering sharpness to 0(like have been doing)render chroma sampling useless!so clearly be it in 1080p ,1080i or all the lower version!aside from all the urban legend!i dont think we have gained one inch of real world applicability of all the techno!worst gpu maker and tv maker keep adding new feature to the pile lol!so it blurr the line even more !and to make mather worst every time we try to get info on how to set up 1080p or 1080i someone come along and yell:this is better then that!we dont want to ear wich is better then wich!we want to ear :i will use 480i!how i adjust my tv-gpu-os-etc etc etc
same for all other size!cause clearly i bet most of us using 1080p or 1080i are wrongly adjusted!and i bet what apply to a guy with a computer screen wont apply to a lot of people that plugged to a 23 inch hdtv for a bedroom!AAAARRRRRG!HEEEELLPP!

Chroma subsampling is not the past. It will be here probably forever. Their solution is to just keep upping the resolutions and giving us bigger screens. The industry is also disregarding refresh rate, which also is a domain that contributes to resolution.

I wasn't so much commenting on the tech as much as saying I remember this question being asked all the time in 05/06. Don't know much about broadcasting to be truthful.
