RE: UP2414Q monitor issues not waking up as secondary monitor on DP cable
I would turn both monitors and the computer off. Remove the other monitor from the setup. Test only the computer and the UP2414Q using the Dell provided mDP to DP cable and the Dell USB 3.0 Upstream cable. Once setup this way, do some boot testing. Does it ever fail to wake up setup as the standalone primary monitor?
