Is there any way to tell from just looking at a Radeon's DVI connector (or some other physical component on the board itself) whether the card supports dual-CRT?

I have an adapter comming straight from ATi, and would like to purchase a card to go along with it.

Avoid cards with Radeon-256 aka 7200, these don't do dual heads. All other chips, Radeon-VE aka 7000, 7500LE, 7500, 8500LE, 8500, are dual head capable.

Not true, Powercolor Evil Guardian is a dual head 7200 card, (DDR too!)

AFAIK, other than the RADEON 8500LE 64M S (supports CRT + DVI, not dual CRT's) All Radeon cards with a DVI AND VGA connector (must have both connectors) supports dual CRT's with a DVI>VGA connector on the DVI port (the port is analog and digital). IIRC, search the hot deals forum, I believe there was a thread concerning the RADEON 8500LE 64M S.

I've had the Evil Guardian until a few weeks ago. Yes it does have dual outputs - but it can't run dual content. You can connect almost any combination of CRT, DVI or 2nd CRT, and TV, but all you get are multiple copies of the same screen content. The reason is that the Radeon 7200 chip (the original Radeon-256 with a new badge) simply doesn't have that feature.

My retail shop fell for that trap just as I did (hey, the box says "Multi Display Edition" after all ...), and then found that there definitely is no multi-screen capability in there. They took the E.G. back and gave me an RV2LE (same price, 7500LE instead of 7200), et voilà, dual screen no problem.

So, no hydravision support, no theater mode to the secondary monitor? Good gawd, why would anyone want to clone to another monitor? Clone to the TV or VCR...yes....yikes, no wonder I always buy "built by ATI" cards.

Cloning outputs does come handy when one of them is a TV or a beamer. Of course with the appearance of 7500LE cards there's no point anymore in buying 7200s.
