Thu, 13 Dec 2007 16:49:50 +0000 http://hdguru.com/?p=13#comment-13961 I have a comcast DVR box set to 1080i, 16x9. My TV is A Sharp Aquos LC 42D62U, 1080P. What happens to a 720P broadcast,ESPN i.e, as it comes out of my DVR then goes into the TV? I am of the understanding that my box deinterlaces the 720p to 1080i then my TV converts it to 1080P it's native resolution. Would I be better off changing the output of my DVR to 720P then the TV would simply upconvert it to 1080P? Am I losing anything with it set to 1080i being that the box converts it then the Tv coverts it Again? Thanks I have a comcast DVR box set to 1080i, 16×9. My TV is A Sharp Aquos LC 42D62U, 1080P.

I recently purchased a Samsung 50 inch 720 DLP. Also I have a directv hd receiver that can get 720 and 1080. Here is where I am mixed up, is it ok to watch my 720p set using the 1080p signal? Hope to hear from you. Thanks again. <strong>Yes its OK, though the DirecTV signals are either 720p or 1080i not 1080p.

Whenever I do, the picture is always bigger than the screen. In other words part of the picture gets cut off. I know this because I will only see part of the Discovery watermark logo in the bottom corner or text put on the screen is cut off when it is at the edge. How do I fix this? Thanks. <strong>You don't mention which 55" you have (CRT rear projector or microdisplay LCD/SXRD?) First check the aspect ratio settings on the TV (it should be set to "full) and the cablebox (should be set to 16:9) if not change it. If both are set correctly, and it is a CRT rear projector a "qualified" techicnician or ISF calibrated to reduce the overscan and redo geometry and reconverge the display, though it will cost you money (my guess is at least $200 probably more, its is very time consuming to perform). If it is a microdisplay you are out of luck.</strong> <strong>The HD Guru   </strong> I have a sony 55″ and like to watch Discovery HD through a cable box.

I am very happy with the TV with one exception. When I watch HD live sports, for example, their seems to a lot of digital noise (pixlation problems). This mainly happens as the camera moves around. When the image is still, the clarity is perfectly fine. Having said that, I have watched other HD shows which do not have this problem. What is causing the pixlation problem? Can HD signals be transmitted differently from one channel to another? Thanks! <strong>Yes. You do not mention if you are receiving HD via cable, satellite or over-the-air.  If it is one of the first two you may be seeing pixelization caused by the lower bit rate that many cable companies and both satellite providers use.

I know that thought can be an endless cycle, but I am partial to all black frames. I would also love to have a plasma in this size without speakers.

Also if native cant' be changed then if you get a 720p signal what happens does it mesh it into more lines to achieve the 720p picture. Since you can't physically change your pixel count. Also if you do have the hatachi is it possible to change the chip or the software or both, to produce 1080p. Just wondering but i am sure the wouldnt ever do that but is that really the difference as far as i and p in the processing of it. <strong>HDTVs "scale" the image by interpolating the source signal to the native resolution of the display.
