I can't believe you can't tell the difference (though there may be other factors at work)...talking about the 2 repliers to your post...

I was using the blue VGA connection for a month before I realized ( I read somewhere) how much better DVI is, well, I took my DVI, and plugged it in and the picutre is 10 times better and more detailed...
the monitor I have been using (a 2005 FPW) also operates better in the higher resolutions with DVI - the picture is sharper, the response time is better...
maybe you guys need glasses! lol

But, don't fret, all you need to do is spend $5 on a DVI splitter cable.
it plugs into your graphics card DVI slot and splits into 2 DVI
female acceptance plugs. I just got one and also have another monitor on the way (a 2405 FPW).
I plan on having the 24 inch in the center with the 20.1 inch Widescreen flipped into Portrait mode along the right side of the 24 incher...
should be rather fabulous...Plan on 4 tabling on the 24, and 3 tabling vertically on the 20.1 inch...

How's the 2001fp? I hear everyone loves it? One guy on here has 2 of them with a 2405 in the middle - now that's a display setup!!!
