Just bought the LG 27UD69P-W 4K display to add to my new 5K iMac. I am using a USB-c to displayport cable purchased from Amazon (cable has all good reviews). I have the display working, but when I boot, it doesn't come "on". Mac OS recognizes the display, but it seems I need to unplug from thunderbolt port, and then plug back in to get it to come on. Any ideas what might be wrong here?
I also want to add, that side by side, the iMac is significantly brighter. Is there a likely brightness issue with the LG, or am I just spoiled by how awesome the iMac 5K display is ?
