Poor Image Quality!

post #1 of 6
Thread Starter 
Hello all,

I finally got the chance to hook my PC up to my 40" LCD TV, and it looks amazing. I've even got the audio routed through the HDMI cable. I think I may have to build an HTPC this year...

I wanted to try out my TV Tuner - it's a Pinnacle PCTV HD Pro Stick, so I used the included software. The EPG didn't wasn't worth a hoot, so I tried GB PVR, and that wouldn't work with my Pinnacle. I finally tried BeyondTV (21 day trial), and it found every channel (even the HD ones) and I can get both video and audio.

Unfortunately, the picture looks like crap I'm pretty sure it isn't my video card - I just got done watching an HD trailer of The Hulk from Apple's website and it was beautiful. Even games look amazing, but watching live or recorded TV is awful. Do I have a setting wrong, or is that stick just worthless? I've even tried updating the drivers for it, but the image quality didn't improve

Thanks for any help you can provide

EDIT: I forgot to mention that, when I use the same cable with a TV, the TV's picture looks fine.

What do you mean when you say, "watching live or recorded TV is awful"? What does it look like? Is it pixelated, or distorted, or not a clear signal? Also, I'm sure you thought of this, but keep in mind that high-def is considered 720p and up--so the TV channels might only be broadcasting 720p while I'm assuming your TV is at 1080 resolution? If the TV displays movies just fine that you play from a streaming source/DVD, then I'd lean towards either a bad signal, not a true HD signal, or the HD tuner not working properly (which you mentioned already you don't think is the problem).

Also, when you watched recorded movies/shows from your TV tuner, are they truly high-def? 'cause I thought recording streaming high-def (720 or 1080) is very CPU-intensive. Is the signal being down-sampled somewhere along the line? 'Cause that will obviously cause the image to look like crap.

When I use my cable box with my TV, SD channels look much worse than HD channels do, but I can still stand them.

The picture is both pixelated and unclear - like I'm trying to watch TV with rabbit ears. My TV (Sony XBR) does 1080p and everything else coming from the PC looks fine.

I'm going to try the HD antenna to see if that looks any better. I won't get a chance to mess with it for a few days since I'll be out of town. Thank you for the suggestions

Oh, you'll definitely want to use a HD antenna if you're tuning HD channels--my roommate got a HD antenna when he started watching over-the-air HD TV, and it definitely makes a difference over no antenna. I think that might be your issue. And even a slight loss in HD signal can make a huge difference in picture quality. I'd say that's your next best bet.
