The TVs I've hooked up on HDMI display exactly what I send over. But as folk have a lot of ratty old Standard Definition (SD) video it looks bad on HDTV. There is no real fix for that.
Your post lacks detail so I can't guess if that is the issue or you are cloning your display and running afoul of another issue.

I connected my PC to HDTV using a HDMI cable, but the picture is bad. My PC has both HDMI and VGA output, VGA plays much better picture on a monitor, however VGA cannot be plugged into my HDTV because my HDTV doesn't accept VGA.
What can I do? My HDMI can't transmit high quality picture, but my HDTV can't accept VGA signals...? Maybe buy a better video card that transmit high quality HDMI signals to my HDTV???
