ON the back of this set, which, by the way, is a nice little desktop 1080p set, there is a DVI input. It's an "either/or" input coupled with a VGA input.


In the manual, the claim is that it supports 1920x1080 at a horiz. freq. of 67.500; vert freq 60.00 and a pixel clock freq of 148.5


But primarily, I was told 1920x1080 no problem.


So I plug in my satellite receiver (Motorola DSR-505), which has a DVI output.


Samsung says: "not supported mode"


On the front of the receiver is a button for dialing thru different outputs, one being 720p, and something called "native", which is supposed to sense what the broadcaster is sending and adjust accordingly. This is the mode I use with my 52" Samsung and all is good.


But with the little 23", 1920x1080 via the native mode won't register - have to dial down to 720p to get a picture.


So, is the set likely not working properly (brand new), the receiver sending some strange flag over DVI that the Samsung doesn't understand, or is it likely a marketing lie, and the set can't display 1920x1080 HDTV?


PS - and this is the odd part, the set WILL display 1920x1080 if fed by a nVidia 6200 computer video card.

It could be HDCP missing from the Motorola, I googled Motorola DSR-505 HDCP. The Nvidia 6200 has HDCP.

Thanks - the satellite company updated the firmware to make HDCP active. I imagine it is another in the on-going mess that is HD implementation.

So I got an answer from Samsung today. Apparently, 1920x1080 HD from a computer is different than 1920x1080 from a satellite receiver, DVHS machine or cable box. They couldn't explain it any better than that.

Since I'm not a tech guy at the engineering level, does anyone understand that? The Samsung sees 720p, 4801 and 480p just fine, but won't display 1080 from the satellite box.

It will, however, display 1920x1080 from the Geforce HDTV card.

It's most likely a computer monitor with a tuner. Force 1080P(not 1920x1080) in the control panel and see if it works. I know you can do it with ATI cards, not 100% sure about nVidia, but you would think you could.


It's the same resolution, but most TV's react differently. For instance setting a 360 to 1080P might now work, but if the 360 recognized it as a computer monitor(DVI) you would have PC resolutions(1024x768, 1280x720), instead of 720p, 1080P.


Check your manual.


An example 42" plasma with a resolution of 1024x768 might not work when you set the resolution to 1920x1080, but if you force 1080P, so the TV thinks it's just receiving signal from anything other then a computer it works fine.

I don't think I can force 1080p from my receiver - 1080i may be it's highest resolution. And I think you're correct - it's actually a Syncmaster with a tuner, so it's not likely HDTV is it's primary design protocol.
