I have also recently bought a new Samsung tv (UN46C6300). I hooked it up to my Telus STB/PVR and I was able to get the feed. My issue is with how crappy the SD channels look. At first I thought it might be the tv itself, but when I watch an HD channel the picture looks absolutely amazing. I am using a HDMI cable from the STB to the tv because I thought that would get me the best quality picture. Do you have any suggestions for me in the terms of setup etc that I may be overlooking. It is at the point where I do not even want to watch any of the SD channels I used to.

Sorry If I am posting in the wrong place but I saw BigOil had an issue with his Samsung LED as well, so I thought this might be an appropriate thread.

Thanks

Please read the following FAQ addressing your issue. This was included in the "useful post" that was in the thread where you posted. Since that thread was on a different topic (HDMI connections), I've moved your post here.

Thanks for the reply. I have read a couple of these posts now and have managed to get my SD channels looking a little better by tweeking a few of the tv settings. I would like to improve them even more if possible. On one of your posts I believe you mentioned that Samsung tv's do not support 480i signals through HDMI cable. So here's my question...

Would I be better off switching to a component cable (RGB) instead of HDMI, from my Samsung tv to my (Telus) STB? If I read your post correctly this might give me a better PQ on my SD channels.

Thanks again

It's something you could try, but you may not see much difference either way. I'm not familiar with the Telus STB - does it have a "passthrough" mode so that the SD channels are sent out as 480i, or are all signals sent out as one format - say 1080i or 720P.

If the Telus STB has a composite or S-video output, you could also give that a try and tune the TV to that input for watching SD specifically, but again, you may not see much difference. Also remember that you'll then need to calibrate that input.

Some Samsungs do accept 480i via HDMI - usually you press an "info/recall/enter" or similar button to see what the incoming signal is on the TV's remote.

480 Override Off option on Telus STB? Let the TV do the work.

I also have a Samsung LED and as it turns out it takes the hdmi 480i from a Shaw PVR. However the pq is terrible. Changing the stb pvr output setting on my pvr to shut off the override is the only solution.

If I output 480p the TV also looks terrible. My guess is that the Samsung does not do shape correction in the video engine unless the signal is native (override off). This puzzled me for the longest time. But logically the signal has to be digital direct to the tv for the tv software to do a correction job.

I will say the video engine in the Samsung is considerably better than the older power hungry LG LCD that blew up on us.

So if there is a way to adjust the Telus stb to shut off the 480 picture settings override then you might just get a better quality picture. I keep my back light down to cinema level and find that overall Samsung's LED tvs are about the best bang for the buck. If I use the tv stretch it even will almost look reasonable in cropped out 16/9. As good as most of the ShowCase HD ..which in reality is not HD just upscaled 480p most of the time!
