I’m working on getting an i5 Mac mini to display to an LG 4K tv for a studio we’re building at the office. I bought a Club 3D mini DP to HDMI adapter and downloaded/bought SwitchResX to unlock and utilize the higher resolutions and refresh rates. I can get the highest resolution and frame rate combination to work through SwitchResX, but as soon as I reboot the Mac Mini, after the Apple logo loading bar screen passes, the screen flickers and flashes green. I then have to unplug the HDMI cable from the adapter and plug it directly into the Mac Mini which then displays the Mac’s desktop. I can then plug it back into the adapter to take advantage of the SwitchResX resolution for 4K. I’ve scoured different forums to no avail. Has anyone seen anything similar? Any help is appreciated.
