HDMI: How and where from?

[Mr Fujisawa]

Wrong wrong wrong wrong so many times wrong.

Progressive is better if the panel supports progressive natively, mine doesn't, so it's not suitable for me. Mine is natively interlaced at 1920 x 1080, so 1080i is the best option.

PS3 games are natively whatever they're native at. Most seem to be 720p, but there are 1080p ones like Ridge Racer.

Auto detect on your TV chooses 720p, ARR.

No. 1080i looks better than 720p, it's a higher resolution, despite being interlaced (which on a panel that supports proper 1080i will look a lot better).

but remember with a 60fps game like ridge, u are getting lower resolution than 720p (u are getting 60 unique frames of 540lines versus 720 lines for 720p)

LCD is progressive by its very nature, they simply display each field at once, the set will be a native resolution of 1920*1080 but can only accept a 1080i signal opposed to the full 1080p.

You're still getting a progressive image due to the screen and the image being deinterlaced.

No I am not, stop correctly me please, as I was right the first time. My screen is NATIVELY 1080i. Yes, the resolution is 1920 x 1080, INTERLACED. Hopefully now you won't feel the need to say I'm getting a progressive signal, as I'm not.

My bad, thought he said his screen was natively 1080i for a second! Thought that sounded odd unless he had a CRT HDTV or something!

It is natively 1080i. Nope, I have a Toshiba LCD.

how can an lcd be natively interlaced? lcds can only show a progressive picture, whether they are fed it or not. if ur tv cant display 1080p despite having a 1920x1080 panel, then thats some poor cost cutting thats gone on inside, but like it or not u are seeing a progressive picture, either by simply showing a 1920x540 frame twice (if its cheaply done) or some other form of filtering down.

[IanE]

I have no idea, I'm not the manufacturer, nor do I know about the electronics inside. All I know is that my 360 pumps 1080i Kong on the screen and it looks a heck of a lot better than 720p, the resolution is 1920 x 1080 and is interlaced, and my Mac Mini recognises it as that as well.

I'm sorry you can't accept it, but hey, not my problem.

Like it or not? But...I'm not seeing a progressive signal, since it isn't a 1080p panel, it's 1080i. All my electronics know that (Mac Mini, 360 etc), yet you can't fathom it.

The screen is 1920x1080 and refreshes progressively, even if it doesn't accept 1080p input, so it's still natively a 1920x1080 progressive screen. It's just imcompatible with any kind of 1080p source.

please read up about how lcd screens work. the ability to show an interlaced signal (1080i, 480i) does NOT mean it is being displayed in an interalced fashion. only crts can show an actual interlaced picture (whereby every OTHER line is drawn, leaving a black line between each line). lcds HAVE to draw every 'line' on the screen and so convert the image to progressive. this is FACT.

[IanE]

The signal, and what the TV is displaying is 1080i. Saying "this is FACT" doesn't make it so. The Mac Mini says it's 1080i, and it only accepts a 1080i signal on the panel, so it is a 1080i screen.

[Mr Fujisawa]

a lost cause. but please remember how ademant u are that u are right when u find out u are wrong.

[sj33]

Sounds like this is more a case of semantics here.
LCD's are progressive, the 1080i is being deinterlaced. But it's certainly a 1080i screen if your referring to the fact it excecpts a 1080i signal maximum.

LAAWWLL. I said my screen is 1080i, so 1080i setting is best, despite others saying that 720p is better (when it isn't). It is a 1080i screen as it accepts and displays a 1080i image natively. "u are right", cheers!

You're using the Toshiba 42WLT66 model? Reading the passage it says that it can't accept a 1080p input, not that it doesn't display in progressive scan.

It uses Active Vision Prosessing, as it says in the link you gave, to internally de-interlace the image into a progressive scan image.

Toshiba's website states it's a progressive scan panel; Trusted Reviews gives a quick explanation of how it works:

Obviously the jewel in the crown of this TV is the ?full HD? 1,920 x 1,080 resolution, so when you feed the 42WLT66 a 1080i signal you?re getting a true 1080 line picture, rather then once scaled back to 768 lines, as with most of the current competition. There?s debate on whether a 720p or 1080i signal gives you better quality, due to the interlacing on the latter ? however, since an LCD panel is progressive in nature, the TV will de-interlace the signal and the image viewed will be 1080p. I?m in the middle of writing a feature about this and many other aspects of HDTV, which should (hopefully) make everything clear.

I've been looking into that model for a month or two myself. I'm happy to hear it doesn't dissapoint

[IanE]

But it still doesn't accept the 1080p signal, so it'll only ever be as good as 1080i. There is a difference, as the motion isn't as smooth as 1080p (well, obviously I guess), it's evidentely 1080i. So yes, in conclusion, 1080i is better for some (like me), and 720p is better for others, it all depends on the panel. Cheers!

Btw, it's a nice screen, but if you want a computer through it, it cannot be VGA, the panel doesn't accept any images through it, it has to be HDMI or DVI > HDMI (as I have my Mac Mini plugged in).

So my Samsung LE32R74BDX set can display a 1080p picture then?? even though in the manual it says 1080i for max display? Not sure what the native res of this TV is though, althouhg i know it i plug the PC into this set with a HDMI cable it auto selects a 1920x1080 display

[Lyris]

LAAWWLL. I said my screen is 1080i, so 1080i setting is best, despite others saying that 720p is better (when it isn't). It is a 1080i screen as it accepts and displays a 1080i image natively.

No it doesn't. It can't display 1080i natively because the signal needs deinterlaced. Of course I'm sure we could argue about the definition of "natively".

Mr Fujisawa is actually correct, although it's really not worth arguing about. There's no such thing as a 1080i panel but "1080i TV" is a good description for something that can't accept 1080p natively and has to turn 1080i into 1080p to show it.

It's the same as all those ancient LCD TVs that listed "Progressive Scan" as a feature but only had SCART sockets as their most capable video inputs. They couldn't accept a Progressive Scan signal but they DID turn Interlaced video into Progressive so got away with listing it.
