The only crime I did was to unplug the Mac from the dock and plug it back into the dock later. I tried both scripts for mac.The same malaise hit my external monitor today. Mac: Run this script ToggleOpenCL.app - disable OpenCL and restart Capture One Download here Mac 10.11 UPDATE: Run this script instead ToggleOpenCLMacOS10.11.app - disable OpenCL and restart Capture One Download here Since my MP is running on 10.13, not sure which script should be used.

Confirm display cable: didn't have another USB C computer to connect to (skipped) Confirm display: connect to another computer (worked) The basic troubleshooting strategies applied were:![]() Reboot computer with display connected (didn't work). Connection sequences: Tried rebooting computer with display disconnected, connect display to computer directly (didn't work). Before I eliminated the docking station I was able to see the CalDigit connected and supplying power, but no display connected even though the display was connected to the CalDigit. Lets you see the Mac's view of what is connected. -> Hardware -> Thunderbolt / Power. Diagnostics: Apple -> About this Mac -> System Report. Adobe flash player para mac os x 10411Power cables: I know this sounds stupid, but check each point in the power chain. The hardware I had been using for the last couple of weeks successfully (display, docking station) had no changes. Recent history: Nothing changed on my computer (at least that I initiated). Googled to find the magical hidden Apple button to detect external displays (System Preferences -> Displays -> hold down Option button to cause magical button Detect Displays to appear), nothing detected. Power cycled display on boot it reported no DP device detected. Detection: Try having each side detect the other. ![]() The Digital Optical port on the back which is lighted is no longer. The blue LED doesn't light. So it's not the panacea I had hoped as I can see some things correctly but not others of significance.CalDigit docking station after all the troubleshooting just died. But in the middle of everything it did see the docking station. The display and cable were working, it was the Mac that got into a state where it could not see external Thunderbolt devices.Sadly I just checked the Mac System Report and Thunderbolt still reports no devices connected to its bus ports. At this point I was in the simplest configuration: display connected directly to laptop and no docking station.Given all my troubleshooting I believe the culprit was the Mac itself. Resetting SMC and p-ram to no avail. Rebooting everything connecting, disconnecting, trying to force find the screen. Screen is blank and turns it self off after signaling "no input found".As I used to work in a store selling apple computers I tried all the regular tricks. Then at one point I closed my mac and turned of the screen, opening the mac up again the screen is not recognized at all. It has worked without issues for over a year. I love the product design and features, but I have one at work, and it's been flakey on occasion (refusing to power up like now).Late entry here but it might be useful to someone so here we go.If your computer has been working with an external monitor but suddenly stopped supplying an image feedI have a late 2016 MBP 15 running Catalina 10.15.4 connected ta an Eizo CG248 via a displayport - USB C connection. Through the hyperdeck also got a 30hz refresh rate. And bought a mini displayport to displayport. Tried again with 2 different display to usb c cords. The hyperdeck specs said it would provide 60hz via usb out but for some reason it did not and the HDMI cord was a 2.0 one. Connected it and got an image but only with 30hz refreshrate that I wasn't able to change, so it wasn't a viable option, as I need 60. Try them out one by one and retry your original connection in between. I then returned the cables I bought since I didn't need them and now I'm back to status quo with my original hardware.Go buy all the cord variations you can connect between your monitor and computer. And it has been working since!So it seems that my computer for some reason had a hangup that was cured by connecting another type of cord, but in my case not through a hyper deck. What?!All the glory in resolution and refreshrate was back. At 30hz.I thought I'd try again to connect the displayport - usbc and. But not my work computer and it was really annoying.I realized that there was one option I hadn't tried, if it was the hyperdeck that was resticting the HDMI i could try a HDMI - usb c cord capable of 60hz. Turn off the monitor (it was not necessary to unplug it). Unplug the monitor's HDMI cable from the multiport adapter. And it's free to try.I recently experienced the same issue: a new work-issued 16-inch Macbook Pro stopped recognizing a Dell monitor connected using an HDMI cable and a multiport USB C adapter.I confirmed that the monitor and HDMI cable were fine by connecting them to another computer, tried two different multiport adapters ( this one from StarTech and this one from Anker) in all four Thunderbolt ports (notably, all the non-HDMI ports on these adapters have consistently functioned without issue), reset the NVRAM (as suggested in Apple's troubleshooting instructions for external displays), and tried power cycling the monitor as suggested in the top answer. If it works it works as It did for me. ![]()
