Hey guys, I have a new to me, MSI Radeon HD 7970 OC model. It's a reference style card. I'll include the link below to the specific model. It's flashed on the bios switch #2 for Mac and it works perfect with a single ACDHD 30" via DVI. The problem I'm having is that I have since added 2 more ACDHD 23" and I have Mini DisplayPort to DVI adapters for those. Last night I tried plugging in all 3 monitors and one of my MDP is not outputting any video signal. The MDP closest the HDMI is not showing signal to the displays. I swapped the displays and sure enough the problem is not the screens. The DVI is powering the 30" no problem, but then only one MDP works. I unplugged the 30" and tried going only with the 23"s on both MDP and nothing either. I plugged in my TV to the HDMI and it only works after unplugging the other 2 MDP. Any ideas what can be wrong with the flash or something to not allow output via the MDP closest to HDMI? My idea is basiacally to not use HDMI and power all three DVI monitors via the DVI and 2 MDP. Thanks.
