promaestro Posted December 4, 2018 Share Posted December 4, 2018 Hi guys, I'm having issues with my displayport. recently installed SwitchResX and accidentally selected the wrong resolution for my monitor. Right after my monitor went blank and shows "input not supported" After following instruction from SwitchResX by deleted monitor profiles, the problem still persist. Strangely, when I connect an HDMI cable to my GPU, I'm able to login pass the apple logo. (unable to do this using displayport) I've tried various things and nothing seems to work even in safe mode. I've attached my bootlog.txt for your reference and also video link. Would appreciate some help. GPU: Sapphire Nitro+ RX580 8GB Monitor: Acer ED273 OS: Mojave 10.14.1 bootlog.txt Quote Link to comment Share on other sites More sharing options...
