I recently tried to hook up 3 different monitors to my Radeon HD 7870 graphics card. The monitors are:
1x Acer G185H
1x BenQ GW2255
1x Some off brand monitor a friend gave me...have no clue what brand it is, has no markings.
I have the Acer hooked up via DVI-I (to VGA), the BenQ via HDMI (to DVI) and the unknown monitor via mini DisplayPort (to HDMI).
I thought I remembered reading that most Radeon GFXs that were 5000 or higher could support at least 3 monitors on one card...I also remember that the article said that you could only hook up 2 through Legacy ports (DVI, HDMI) and 1 (or was it 2?) more through DisplayPort.
Does anyone know if this is true or not?
Yes, the card can *technically* support up to 9 monitors - but that's using AMDs Eyefinity technology, when Windows treats the monitors as if they're one...(plus it only has 5 physical connectors...) I'm wanting to be able to have three different windows open on each monitor.
Even weirder, it won't let me duplicate the Acer and the off-brand (they are both 1366x768, whereas the BenQ is 1080p) - this isn't optimal, but certainly better than having them go to waste.
