Quick Question about Samsung HDTV

[Tristicus]

Alright, so I'm watching my grandparent's house this weekend, and they got a new TV. It is 27" (I think), so I just assumed it was 720p. When I plugged in my PS3 however, it gave me the option for 1080p, and that was awesome. I got to thinking though, that it could only be 1080i. Would the PS3 still recognize it at 1080p/60 even though it is only 1080i/60 though? Or is it really 1080p? I don't know where the box is or anything, or know the model number.

How'd you hook it up?

Practically all modern HDTVs can accept a 1080p input. My plasma with a 1366x768 resolution can do this, and it will state 1080p as the resolution from the PS3. It's best to send the 1080p signal instead of a 720p signal, because the TV will still look better from the extra lines of resolution even though it won't display all of the detail.

 

[Tristicus]

Hooked it up via HDMI.

 

[ChAoTiCpInOy]

HDMI auto senses what input the TV could receive so by that logic the HDTV is 1080p.

You guys are confusing the signal with the native resolution. A TV with a 1366x768 resolution (most "720p" TVs) will always display a 1366x768 resolution (unless placed in 1:1, dot-for-dot mode which is usually called PC mode, but that's for a totally different discussion). Any current HDTV can accept a signal of the following resolutions: 480i, 480p, 720p, 1080i, and 1080p. The TV will then possibly scale and/or deinterlace the signal to be displayed at its native resolution (usually 1366x768 or 1920x1080).

Your PS3 is simply sending a 1080p signal to a 720p TV. There's really nothing more to it than that. Your TV will scale the 1080p signal the same way it would scale a 720p signal (since it's native resolution is not true 720p, which would be 1280x720). Sending a 1080p signal to a 720p TV doesn't make it a 1080p TV any more than sending a 720p signal to a TV with a 1080p native resolution would make it a 720p TV.

In other words the resolution of the signal source and the native resolution of the TV are two totally different, completely separate things and should be viewed as such.

 

[Tristicus]

Well, the resolution is 1920x1080 when displaying things. I think it might only be 1080i however.

What's the model number of the TV? How do you know the resolution of the TV (and not the resolution of the source) is 1920x1080? My 1366x768 resolution TV will say 1080p in the upper right-hand corner, but that's the resolution of the source and in no way changes the native resolution of the TV (which is the resolution that's actually being displayed regardless of whether the source is 480i or 1080p).

There are no 1080i native LCD's or Plasma. It's either a 1080p or 720p TV, most likely its a 720p TV.

 

[Tristicus]

Don't know the model of the TV, if it is on the back I can maybe find it when I get back there today. When I plugged my PC in via HDMI, I was able to set it to 1920x1080, which it said 1920x1080i in the corner. My PS3 displays 1920x1080 in the corner when I select only 1080p.

Yep, that would be the signal then and not the native resolution of the TV. The TV can accept 1080i signals (like from the PC) and 1080p signals (like from the PS3), but that's totally different than the native resolution of the TV itself.

If you were going to use this with a computer, you'd probably want to put the TV into PC mode and send it 1360x768 resolution. Not all TVs specify a TV mode. I just bought a 32" TV to use as my computer monitor, and I had to go into the advanced picture settings and change the HD size to size 2 for it to do 1:1 pixel mapping. I thought that was very strange, because my plasma automatically detected the signal from my HTPC as being a PC and placed it into PC mode without any interference from me. It's a 720p TV, and I send it 1360x768 resolution.

 

[Tristicus]

Eh. Well it is a LN32B360C5DUZA regardless. So 32" I guess as well.

 

[Tegeril]

And it's a 720p tv then with a native res of 1366x768.
