'$500 monitor that I specifically paid extra for so I could get higher quality and support'. Connected a Mac Book Pro to the U2718Q over HDMI - Works 3. Connect my GTX970 to U2718Q over DP - Works 4. Booting with nvdisable=1 disables the drivers but still a black screen with HDMI 5. Changed resolution with SwitchResX to 1080p - HDMI works - returned to 4k 60Hz - No signal.
I've got a Dell P2217 monitor and I'm trying to connect a Macbook to it from the laptop's HDMI output to the monitor's HDMI input. I've tried it on two different Macbooks, but the monitor says it's not receiving a signal. I've tried holding the power button on the monitor for 10+ sec with everything unplugged and resetting the macbook settings (command-option P R). I haven't tried another HDMI cable, so that could be the issue, but are these even compatible to begin with?
