Difficulties with the MST hub and new graphics card

3 replies

Ive been running the MST hub, the 5300 with my XFX 7970s in crossfire mostly without issues for awhile now. Upgraded my video card to the R9 390 and updated to new catalyst drivers. I am now have issues configuring my screens. Catalyst keeps glitching out everytime I try to set up eyefinity.+

Hi Gooky,

Try to shutdown the system, drain your PC electricity by unplugging the power cable and pressing the power button. Also unplug the MST Hub from the power cable. Let it sit for 2 minutes and try again.

Kind regards,

Finally got it working. Had to set up eyefinity a different method. Kept trying to detect all the monitors but catalyst would glitch out once all monitors detected and trying to enable eyefinity. Solution to this was to enable all the monitors by creating an extended desktop and turning all monitors on this way. After that, use catalyst to create eyefinity through current arrangement.


But paul, I still encounter the same issue as before and not sure if there is a solution to this. Prior to this video card, I had dual 7970s with the MST hub going from DP to mini DP into the graphics card. Everytime the monitors go to sleep, eyefinity fails to work upon waking the monitors up. I upgraded video cards and now connect with just the display port. Updated catalyst drivers to 15.7 which is the latest full release as of today and still the same issue. Monitors work perfectly fine until they go to sleep. After that, everything gets wonky and arrangement goes out of whack. Has a solution been figured out for this?

Hi Gooky,
We found the sleep issue with older mainboards only (starting 4 years upwards). We believe it is the BIOS behaviour that is causing the sleep and not wake up. So far we have not found a solution to this.
