Hi all. I am running a single 6870 with three monitors which are all identical (1600x1200 but I have them in portrait) in eyefinity and a fourth running separate. Eyefinity runs great on a lower resolution of 3072x1280 but if I up the resolution to 3600x1200(which are the screens native resolution) one monitor goes blank but the other two work fine. I have tried several trouble shooting attempts to resolve this issue to no avail. I disabled the fourth monitor for the following troubleshooting attempts. With two DVI and one active Mini Display Port 3072x1280 - works fine 3600x1600 - works fine But in this config the fourth screen(HDMI) will not work since I am using two DVI outputs. With One DVI and two active Mini Display Port 3072x1280 - works fine 3600x1600 - One screen that is connected to the mini display port goes blank but the other two work at the proper resolution. Can I rule out that one of the Mini Display Port adapters are faulty since it does work on the lower resolution? Anyone with any ideas or troubleshooting procedures I should attempt. I'll uninstalling then reinstalling the drivers now. Any ideas would be appreciated. |

Up date for anyone who Googles this having the same problem. Eyefinity with two DVI and one Active Mini Display Port. 3072x1280 - Works fine. 3600x1600 - Works fine. Swapped Active Mini Display Port with the other Active Mini Display Port. 3072x1280 - Works fine. 3600x1600 - Didn't work. So looks like one of the active Mini Display Ports is either broken, no longer active or can't handle the higher resolution. Just bought a HDMI to DVI adapter and hope I can run the fourth monitor off of this via the (Non?) active Mini Display Port. Hopefully saves me having to buy another active Mini Display Port. |
