Samsung 52B750 -how to change 720 to 1080i?

[rivbyte]

Hi, I have the following...
Samsung 46" A750,
Time-Warner HD/DVR,
Yamaha receiver RX-V665

When I change to any channel, it mostly displays 1920x1080i up at the top left corner. My brother recently purchased the Samsung 52"B750 HDTV. he tells me that when he changes his channels, it displays only 720p. I was over yesterday and looking through his 'instruction pamphlet, and I could not see it anywhere, how to change to 1080i from 720 on his menu or tools from his remote.

He has Dish Network. I realize no one broadcasts in 1080P, and the only way to get it is with Blu-Ray, but watching football yesterday was kind of pixelated in 16:9 aspect. His 240 Hz MotionPlus was set to smooth.

His there a way to switch from 720 to 1080i?


*On another note...I'm still having issues with my HD/DVR Cable box. The picture completely blacks out, sound remains on. This happens about five to ten times per hour, and drives me KRAZY!!!.

I called Time-Warner and they told me to contact motorola..I contacted Motorola and they told me it had something to do about the repeater architecture having handshake issues...has any one else experience these blackouts? My Motorola box is a DCT-8416 III. Time-Warner has another box out now and that's a DCX3400, and wondering if that would be the fix.

Thank you all for any help on this.

I don't have a lot of experience with cable or dish, but I'll give you a first shot.

The TV displaying the 720p or 1080i indicator is probably just telling you what signal it's receiving from the source. No matter what kind of signal it's getting, the TV is going to be showing you 1080p in the end, since that's what the TV physically displays at the end.

In your situation, you're getting 1080i most of the time since that's what is being broadcast by Time Warner (with some 720p channels).

For your brother, you'll have to see what the dish network receiver box has for output options. It may be the case that you can set it to certain resolutions only or passthrough of the original source content's resolution. There may be check boxes to enable certain resolutions.

You were probably looking in the instructions for the TV when you should have been looking in the instructions for the Dish Network box?

Pixelation might be a result of 1080i being converted to 720p by the dish box, and then the TV going back to 1080p.
It might be caused by the compression in the original signal though.
It might have been artifacts created by any piece of electronics in the chain.

For your own HD/DVR box, how do you have it connected now?
If you have video running through the Yamaha, can you try to just hook it straight up to the TV to see if that helps the issue? (Audio goes to the Yamaha, Video goes right to the TV).
