Using an 2048MB ATI AMD Radeon HD 7800 Series (XFX Pine Group)
Otherwise branded as the GFX Double D 7850 series GPU and three displays.

All three displays, after some tweaking around, work fine. Meaning most of the time, all three screens are set up fine, work, no issues noticed at all.

The only time I have any issues is when I restart my PC. Almost always, sometimes not. If I restart my PC one of the three monitors will not want to work.

Anyone who works with three displays on a single card knows the headaches with Display and Mini Display port adapters. Ultimately, I know my Mini Display port adapter works, sometimes, because it... well, works. sometimes. I can't help but think it may be the adapter, and I have it wired weird due to the Mini portion. I've got a Full display port connected to my DVI which leads to a mini display port adapter. Again: It works. most of the time. Again- When I restart my machine my Mini display port simply does not want to work. I'm using all DVI, all same Monitors ( ASUS VS238 (1920x1080@60Hz) )23 inch Asus.

Essentially, When I reboot machine, third monitor won't work. Sometimes unplugging/plugging back in will sometimes work. In the case today I have switched all three DVI Cables multiple times as well as Mini DP ports. All monitors will work, just not all three at same time. I've updated to latest drivers from manufacturer, ensured all monitors work in any pair of two's by themselves.

Even just removing a DVI and leaving ONLY the mini DP plugged in it will not work- and I can completely believe that it's a good chance my adapter may be dead- but i'd love to get to the bottom of it before replacing it as this is a very well known issue and there's multiple threads about it all over the place just not with same circumstances or any real fixes. I really don't want to believe my $60 adapter is bad when just screwing around with it will usually fix it...


Any Ideas? Would be greatly appreciated. Also posting this to Manufacturer website and help forums to see if I hear anything back.

I didn't understand this dilemma well understood a little bit but got lost in the middle. If you could post the picture of the back of the graphic card and the adapters that are connected it would clear alot. Did you try just using the mini DP adapter with one monitor to see if it gives display? Leave the 2 monitors for a bit and test things on one monitor and post the results here.
