UPDATE on where to buy these cards...
Concerning the Gainward CARDEXpert GF2MX TwinView GS:
I looked around on
gainward.com's website and found the email to the US distributor for them. (Go to 'Contact Us' > US distributor... the email address is right there..)
Here is the reply:
"You can try
www.mixpc.com or call our distributor AVUS 626-333-3833."
Concerning the KDS computers , here is the reply I got, when asking if the CardExpert Geforce2MX dual head is a dual VGA card:
"It is Dual VGA (dual Head) and also has a video out port It is retail box and has driver CD.."
So there you have it.
5 speed: The E-VGA twinview cards can do different resolutions.
E-VGA TwinView FAQ
I was just as suprised as you were to find that these come in straight dual VGA- the dual head was exactly what I was looking for. Notice that (i think) 3 of the links at the top of the page are dual-VGA cards. Also note concerning using 2 CRT monitors and an external TV-out: the e-vga site says "Please Remember: For TwinView output, you can use only two different outputs at one time, so even on cards with more than two outputs, you will be limited to using only two at a time."
