However, if I use a VGA adapter from the DVI output on the graphics card, the picture looks great. Does anyone have any pointers for me as to how I may use a HDMI cable and get as good of quality? Thanks!
As you have a nvidia card and getting a poor hdmi image on a hdtv then i'd suggest doing what is in the following link, oryou can use one i have prepared.
Fixing Ugly DVI/HDMI Displays due to EDID bugs on nVidia drivers
The good news: nVidia finally released their much awaited 173.14.09 video driver for linux. This officially supports the 2.6.25 kernel and supports the newest line of GeForce graphics cards.
The bad news: When you install the driver your HDMI/DVI digital flatpanel display looks horrible; the text looks jagged or blurred or oversharpened. There are halos and ringing anywhere there is contrast. The colors looked washed out and over bright. However, when you use the D-SUB (VGA) plug, everything works fine
The file i have included is a edid with it's extension bloc deleted, this will most likey fix your issue, or you can follow the tv and make a edid from your own hdtv's edid, all the relevent info is included in the link.
Sadly when megaupload went down i lost alot of edids so the included one is actually from a zalman 3d monitor, i've included this as it has no extension bloc so will fix your issue i'm 99% sure., do'nt worry it will work the same as the one you create in the tut above except it only has a 1080p res and no audio, dno can't remeber., you can allways unistall the edid in device manager from your tv

Just remembered that when i got my 670's i needed the modified edid that is in the tut in the link and the software needed to capture/make it did'nt work with 600series or just the 670 so you may not be able to complete the tutorial.Edited by OcSlave - 10/11/12 at 5:00am
