HDMI and Component on Same TV

I recently read a post from rbinck about increasing the plasma picture quality of SD channels by setting up component cables. Is this possible to do with the DTV HD unit and the 50 inch Panasonic Plasma TV? Has anyone else done this and thought their PQ was better? Any advice on how to do this would be appreciated. Thank you

Send rbnick a private message and ask him, he will definetly be able to help you, also he is a moderator on this forum in case you didn't know.

I'm not sure what he said, but i can't imagine component being better than HDMI?? HDMI is a better type of cable.

The only thing I can think of is SD channels look bad on HDTV's when theyre upconverted. Maybe using a lesser quality cable will show you less of the detail, in essence you won't see all the imperfections that make the SD look so bad.

when you upscale an image you do increase the finer details, but you also magnify the imperfections as well. Little fuzzies become giant fuzzies.

Like I said, PM rbnick for better clarifiction.

On many plasma screens I have found that there is a chance that SD will look better when using component cables over DVI or HDMI. Additionally I have found that SD will also look better using s-video or composite rather than any HD connection. The reason could be a difference in the processing and scaling. Many HDTVs will only provide the video processing they have on SD level signals. This would mean the misquito noise and jaggies removal will not occur through the digital connections. Also many source devices (STBs) will have better SD outputs on the analog over the digital. I assume this has to do with the D/A convertors included in the source box.

But all of that is not universally true, so you have to try the different connections because whether it will yeild an improvement or not will depend on the particular equipment.

I think you are on the right track here. Also many 50" panels are 1366x768 and the scaling ends up pretty weird going from SD to HD to native when a digital connection is used.

Bottom line is try the different connections and see for yourself.

To follow up on this a little. I have the h10-250 and the 50" Panasonic HDTV. Can I hook up both HDMI and component cables at the same time to watch certain channels via HDMI and others via component? I wasn't sure if when I hook up the HDMI if it would disable the other connections. Thank you

Yes you can. Simply hook up both, and then you can cycle through your imputs to change which you're watching!

This has been discussed. I have tried this. If you have HDMI hooked up from the 10-250 it will disable any other video outputs. From my experience you can not use any additional video outputs when you are using the HDMI connection. If I am wrong I would appreciate someone telling me how to do it correctly.

It must be different then on the H-10. I am using both component and HDMI and can cycle between both as we speak!

Actually, I just did it and it worked just fine. I hooked up an S-Video and a RCA video on two different inputs. Now the testing will begin with hockey comes on tonight.

You will need to adjust your format when you cycle through the different inputs. Most will only display on 480 and not the higher levels.
