Alienware 17 R2 laptop has embedded graphics on the processor (Intel® HD Graphics 4600) and an external graphics card (GTX 980M).
This computer has switchable graphics, it is necessary to check with Alienware* if it is possible to use the 3 monitors using 1 of the graphics at a time.
Intel® HD 4600 graphics supports Collage display with 3 monitors even 4 monitors with a display port hub. The maximum resolution with 3 monitors in collage mode is 2560x600.

HI Mike_C - i am having the same issue but mine did work across all three monitors with the laptop display as part oif the collage. the maximum resolution on my setup was 5760x 1080 and worked perfectly until i downloaded windows 10 and then intel graphics HD control panel could not see the laptop display in collage mode, and it only coudeltn see it in collage mode.
I really need help with this - my entire setup is designed to play in collage mode
