OK, help me out here . . .

by Coryphaeus / March 30, 2009 1:01 AM PDT

I need the reason(s) for using a DVI port vs the D-sub port on my Acer 22" wide screen monitor. My PC has a NVIDIA GeForce FX 5200 video card with 256 Meg of RAM and both ports. The display has an excellent picture using the D-sub at the native resolution of 1680 X 1050.

What benefit(s) will I see using the DVI port?

It's about HDCP

HDCP over DVI is possible. HDCP over VGA is forbidden. I think you know these TLAs.

So the only reason I can think of is to play Blue Ray HDCP protected content.

It's HDCP compliant . . .

I was just wondering if I would get a better picture, or some hidden benefit.

I don't plan on using Blu-ray on this screen.

also, dvi is purely digital and less susceptible to noise

or interference... the d-sub vga signal is analog. a high-res vga signal can appear 'fuzzy' because of noise when using cheap cables or in areas with lots of em/radio traffic.
