need help! can't get egpu to work with any monitor
I have a dell precision m4800 with intel i7 4800MQ, AMD firepro m5100 graphics card, 8GB RAM.
my external gpu setup is with an exp gdc beast via expresscard, with a 220W power supply, and a gigabyte gtx 970. The 970 works fine, the laptop recognises it and the drivers are up to date, but I can't get it to be the gpu my system uses. I've tried pugging in another monitor directly into the 970's DVI port and HDMI port, and plugging in a tv to the HDMI port, but I never get any signal. I would greatly appreciate any help, please ask anything else as well if there's more info needed.
