I am prompted to indicate HDTV settings for my Dell 1703FP ultrasharp flat panel digital, installed on my Dimension 8300 with Nvidia Geforce FX 5200.  I use the DVI outlet, and also have a 17in CRT hooked up to the analog.  Is this HDTV compatible, and what would be the preferred settings?    The newer Nvidia drivers promise better HDTV, and I'm currently, albeit with difficulty, installing an ATI HDTV Wonder card.  Thanks for any answer to this.
