Which Video Card is better for a HDTV Aquos 720 and VGA Monitor ?

I have a HDTV Aquos LC-40D37U. It is 37" and 720.

Also, I have a standard Monitor.

Which Video Card do you recommend to use with both display (HDTV and standard Monitor).

I am specially interested to have super great quality picture in HDTV but monitor can be switched when I prefer use my monitor.

My HDTV has HDMI inputs and Red-Blue-Green inputs.

My monitor has VGA (No DVI).

Thanks for any help.

I do this question because I tried and old video card on HDTV and it showed medium video quality. The words were not very easy to read as compared in my monitor which show an excellent video quality.

Since I am not very interested in large size PC Games, which Video card would you recommend not very expensive?|||I can use any newer Nvidia|||Theater™ 650 PRO
