Dual Monitor Recommendations
Hi folks. I need some advice. I have a system with dual EVGA GTX980 Ti cards currently in SLI. I have two monitors that I want to put into a dual monitor configuration. The primary monitor is a Dell UP3216Q with a 4k resolution of 3840 x 2160 pixels. The second monitor is a Dell U3011 with a resolution of 2560 x 1600 pixels. Currently I have the monitors both hooked to two of the mini Display Ports on one of the GTX980s (the first one closest to the CPU). Both monitors work and the "desktop" spans across the UP3216Q continuing onto the U3011 as the mouse is moved from left to right. I really think I want the displays to be totally independent from one another and not have the desktop spanned across the two. Possibly have two separate "desktops" if you will where program launch icons on the secondary display would launch the program directly to that display and not have the launched program appear on the primary display would be ideal. Is it possible to use the two GTX cards independently? Will I have to remove the SLI bridge and simply connect each monitor to its own card? Or is there a software setting that would allow me to make the displays independent of one another? Your thoughts would be appreciated!

no. DWM and explorer.exe are single gpu context only. any amount of 'gpu util' on the second card is just to output what has already been prepared and copied across from the gpu attached to the primary gpu. It is an ongoing failing on microsofts part to take advantage multiple device contexts.

Thanks Sora.... even if it is bad news for me.

You must have implemented the "surround" feature in Nvidia's control panel, if the desktop is spanning across both displays. Uncheck it and right click your desktop, select "screen resolution" and in the window that pops up, select extend these displays. This is for W7, 10 should be similar?
