I have an INSPIRON 3847. It has VGA & HDMI outputs. I want to run 2 (or if possible 3) monitors. Had 2 monitors running with GX270 but had to buy new Video card & a splitter. Do i have to buy a new video card for this one also or just use a VGA splitter, or HDMI splitter? Was told by Dell Tech that i could run one monitor from VGA (how it's been since day 1) and another from HDMI but did not work (used HDMI to VGA cable). What's best and/or cheapest way/ways? Thanks.
