I've got a decent machine, 8 GB RAM, good motherboard etc and an Radeon HD6870 GC. I'm desperately trying to run three monitors on the card. The card has 1 HDMI, 2 DVI and 2 Mini DisplayPorts. The set up is as follows:
- Monitor 1 is connected via the DVI cable.
- Monitor 2 is connected via a DVI to HDMI lead into the HDMI slot.
- Monitor 3 is connected via a DVI lead into a DVI to Mini DisplayPort adapter.
Now, in Ubuntu, I have no problems whatsoever, they all work completely fine as extended desktops. Windows is seeing none of this. I've got the Catalyst Control Centre, and I tried setting up an Eyefinity group, but I can only ever have 2 enabled at once.
idk what the problem is as I don't have your particular card. I got a really generic card from VisionTek and it works fine with 3 – RobotHumans – 2012-02-28T13:34:11.850
How did you manage to set it up? – Aaron Lee – 2012-02-28T13:57:51.193
Try to use the Windows display settings instead of third-party programs. Catalyst may not support your video card. – kinokijuf – 2012-02-28T14:26:04.560
1I have a feeling that although there are multiple ports, only 2 can be active at once... Or the HDMI is shared with the MDP, have you tried using the 2x DVI and 1 HDMI? – HaydnWVN – 2012-02-28T15:18:08.033
On my card I can have 2 DVI and a displaylink port all active at once through catalyst. I haven't tested the fourth port as hdmi yet. On an interesting note, getting it to play nicely on recent linux has been a PITA for me...so I guess you take the wins where you can get them. – RobotHumans – 2012-02-28T17:25:42.123
This is still a big issue, I've now updated the graphics card (which turned out to be faulty) purchased and installed an 850w PSU, so I know it has enough direct power, but now, I have them connected the same, it still doesn't allow 3x1 Eyefinity groups, someone please help. – Aaron Lee – 2012-03-08T15:24:05.363
Which version of windows are you using? If it's XP or older you won't be able to enable eyefinity groups. Windows 7 is required. – user3490 – 2012-03-05T22:49:25.380
