Graphics card: 2x Gigabyte HD 4850
Mobo: Asus P5Q-E
OS: Windows 7
Monitor: Acer H233H
Can you please provide a step by step as I am new to this. Also, I have both cards installed but they are not yet connected by the crossfire bridge since I haven't recieved mine yet.
I have 2 monitors working off of my main card, but nothing is coming out of the other card.
You cannot connect 3 displays to 2 cards in crossfire on the 4850. If you want 3 displays while still using crossfire and gaming on all 3, then you have to get a Radeon HD 5xxx series card. You can run 3 displays off of 2 cards, but then you can only use 2 displays and 1 GPU for actual gaming.
Currently it there is no way to do 3 displays with Nvidia at all. They are supposed to be releasing a driver that will allow that sometime in the next couple months, but I'm not sure if it will be enabled as far back as the GTS 250. Really, right now, you will have to disable crossfire/SLI to use the 3rd display, and re-enable it when you want to game on a single display.
