So I have no idea where to start! so ill try to post as much information as possible.
I just upgraded from a ATI Radeon HD 4850, to a Radeon R7770 Ultra Overclock edition.
I was running 4 monitors before i switched, 2 on the main board. (1 VGA, 1 HDMI) and 2 on the mother board. 2 DVI
Well the new XFX Radeon R7770 card has the 2 DVI, 1 HDMI and 1 Display port.
So i conntected 2 moinotrs to the DVI, then i put another on onto the HDMI port on the card. Then i conntected the last monitor to the on board!
heres where it all gets tricky! because it worked before the other way, but i would rather the 3 be on one card and the off monitor on my on board ( i wanna do the eyefinity thing!)
well my computer and AMD Catalyst(the newest one for the card just upgraded) both see all 4 monitors! thats great! Well it will only display on 3 of them at any one time! no so great!
I get an error saying i need to turn one display off before enabling another one! well you do that and it just swaps monitors. am i missing something to get them all working at the same time? its the 1GB DD5 card. It worked before, so i am guessing it has something to do with the card!
Some additional information, i took the old card out of PCIex16(second slot) and put the new one in there. and there is a "switch card" in the PCIex16 slot(labeled 1) my maunal for my board says first card install in second slot, then if you want to crossfire, i put the second card into the first slot. (this is all rambling information considering the "switch card" never changed or anything. Just the graphics card)
i have googled this a bit and all i see people saying is the difference between active and passive ports? or something like that, but that is only on the HD 6870s, and i dunno if thats the same! Please someone help!!!!
