So this is my first attempt at SLI. I have two MSi 670 GTX
Before I get too far into the issue, maybe I should preface that I have 2 different monitors. Both monitors have VGA and HDMI (they do not have DVI) connections. Here are the monitors and setup:
Left Monitor (Primary): 28" Hannspree HF289H
is connected via HDMI
Right Monitor (Secondary): 28" Hannspree HSG1075 HDTV/Monitor
is connected via VGA
Most my work is done on the Left side and the right side is used as an extended desktop where I can show information I may need handy, or in most cases I'm running a movie or TV show while I work. Few other bits of information about my computer:
Windows 7 64 bit
MSi z87 G45 motherboard
8 GB RAM (though I don't think that plays a factor in this)
Ideally, what I want to do is utilize SLI when I game and use the 2 monitor setup I have for everything else.
Silly me, I thought SLI was just inserting both cards and linking them with the SLI bridge. So I've learned through trial and error and I can duplicate the screens, but I cannot have the extended desktop. When I try to set up the SLI, the right side (the TV/Monitor) goes blank and says "NOT SUPPORT!" which is different than "No signal." I've provided an image below:
What's weird is the computer can "see" the monitor as it is recognized in nVidia's control panel and Win 7. I tried extending the desktop with Win 7 - no luck. I tried disabling SLI - no luck. I uninstalled the drivers, cleaned the drivers off with guru3d and re-installed the drivers - no luck. I did notice that when I fiddle with the settings long enough the system eventually loses the ability to recognize the TV/Monitor and it only shows one monitor.
After much wrangling, I couldn't get the setup to work, so I removed the bridge, but the problem remained. I removed the 2nd card, problem remained. I ultimately had to do a clean install to correct the problem (I probably didn't have to go THAT far, but since it was a new build it was easier than researching the problem until I could find the answer).
So I have several questions, but some of the basic questions are:
- Can I use SLI like I want? Use it on a single monitor when gaming, but have 2 monitors when I'm doing everything else (and not use SLI)
- Can I do this with the 2 monitors I have?
- What's the proper way to setup the monitors?
- What's the proper way to install SLI cards? For example, I have one in right now. When I add the second, should I uninstall the 1st in the Device Manager, insert the 2nd GPU, then boot up the computer and have them recognize both GPUs at once, or some other way?
I apologize for the long topic, but I wanted to get as much information as possible out there so we can resolve this issue quickly.
I appreciate your assistance in this.
