Hi. I bought a Sapphire Radeon HD 6870 and replaced a Nvidia 9800GT.
With my old Nvidia, I had no problem running 2 VGA displays via DVI adapters.
Running dual DVI with the Radeon doesn't work. It doesn't read my second monitor at all.
The monitors themselves have a HDMI port, so I have tried that as well plugging 1 monitor in with DVI and the other with HDMI. During start up, the second monitor responded with the same screen as the other, just duplicating it. To me, I believed that was good news, but before I am able to Log In to the OS (Windows 7), it will BSOD on me.
Using 1 monitor works fine via DVI.
HDMI by itself causes BSOD.
Please tell me what I need to do to get both my monitors working with this new card, the card is awesome, but I'm fond of my second monitor set-up.
Also, I looked up the issue (trying to be at least a tiny bit helpful :3) And found this: "The 6870 has a DVI-D port and a DVI-I. You have to run the vga connector on the DVI-I port with an adapter and the other monitor has to be run on the DVI cable. " Hope this helps a bit. As for BSOD when using HDMI and VGA

AMD Radeon HD 6800 Series
Driver Version: 8.861.0.0
as per Device Manager.
As far as a DVI cable goes, I haven't tried that yet. And I will love you forever if it works. Now hopefully I have a cable...
I did a clean reformat last night, retried all the possibilities I had available to me with the same result. No response on dual vga with adapters, and HDMI still BSOD's. The driver version I reinstalled is the same as above.
I will be trying a DVI cable later tonight and will post back with results.
DVI Cable + VGA Cable w/ Adapter was the winning combination. I finally was able to configure it the way my old Nvidia had it. Thank you very much for your help. It's a really annoying feature of this video card, but a twenty dollar cable fixed my situation and I'm happy. Thanks.
