Hi there! Currently using a late 2013 MBP connected to a 27in Dell UHD 4k Monitor - P2715Q and an LG 27in 27EA83R-D monitor. The Dell monitor is connected by a Mini DP to DP cable and the LG is connected by HDMI My plan is to use the Dell as a 2nd display AND maybe the LG as a 3rd for my 2017 iMac. Would USB C to Displayport cables fit the bill? http://a.co/3aWqEdP Specs of my 2017 iMac 4.2GHZ QC I7, TB UP TO 4.5GHZ 64GB 2400MHZ DDR4 - 4X16GB 512GB FLASH STORAGE AMD RADEON PRO 580 W/8GB VRAM Thanks!
