A couple fairly general questions, I think:
* BIOS "letterboxed" via mobo HDMI port
* How can I tell if SLI is working?
* How can I tell if Virtu is working?
When I connect to the gfx card the BIOS is fully visible, whereas through the ASUS P8Z77-I motherboard HDMI port I see maybe 4x3 ratio with the sides and bottom lost and unviewable. Luckily all the crucial settings can be manipulated, but I need to connect to the gfx card to completely use the BIOS. I guess Windows loads a driver that understands the issue, because as soon as the Windows video driver loads I see a full aspect ration and the screen borders are at the edge of the display. It's a Samsung 720p TV LN40A450C1D, if that is useful. At some point I will test the DVI port on the mobo, but I lack the cable so far.
This is my first experience with SLI, so an early thought was to use the EVGA Precision gfx monitor tool to see if the GPU2 core was getting load. It wasn't. Then I ran 3DMark11 and saw the score was on par with a single GTX 460, so I started hunting. I found someone who recommended HyperSLI. With HyperSLI installed I can access SLI settings in the NVIDIA Control Panel.. Cool. Did I mention it's an ASUS P8Z77-I with only a single PCIe slot? I have no idea what HyperSLI is doing (as yet), but it seems to be helping.
So then I tried to get VirtuMVP, SLI, and 3DMark11 all playing nicely. Here, I'm stumped so far. The best scores are connected to the gfx HDMI port, Virtu disabled.
* Connected to gfx HDMI with Virtu enabled 3DMark11 changes the screen resolution, but shows only a mouse pointer on a black background. I need to click the background then press Esc or it just sits there.
* Connected to the mobo HDMI with Virtu enabled 3DMark11 runs just fine, but SLI doesn't work, so I am using only 1 GTX460 and the HD4000. Not too much better than the single GTX 460.
