thunderbolt port in display input as well as output? I posted the question below to the "older displays and monitors" topic pages, but it seems almost no-one reads it and I have not got a response to what seems to me to be a very simple question. My question basically is: can I input video from my MacBook M1 into the Thunderbolt port on the back of my old Thunderbolt 2 27" display (from about 2014), or is it an output port only? I need an alternative way of inputting video into the the display because the display's built in input thunderbolt cable is faulty. Here is the full post to the "older displays and monitors" topic, to which I have received no reply: Quick question about my 27" Thunderbolt 2 display, model no. A1407, circa 2014. This has the standard Apple octopus Thunderbolt 2 input cable combined with a magsafe power connector. I am connecting it to my 2021 MacBook Pro M1 via a Thunderbolt 2 to USB-C adaptor. The Display has 3 USB-2 ports, one Thunderbolt 2 port, 1 firewire 800 port and one gigabit ethernet port. Problem is, the built-in Thunderbolt input cable has become loose or frayed at the output end, and very unreliable. It only has to be lightly touched or jiggled at the output end (near the Macbook) for the screen to go black and then you have to wait for a while for the video to come back, and the computer password has to be entered again. Someone suggested to me that I could just bypass the display's input cable and run a cable out of my MBP with a Thunderbolt 2 jack at the other end plugged into the back of the display -- using the Thunderbolt port on the display as a video input port. So -- my question is whether the Thunderbolt 2 port on the back of my display (or any other ports) can be used as a video input port, or is it just an output port? Thanks

iMac 27” mid-2010 as Target Display, from 2020 M1 Mac Mini, using Big Sur I have this set up working OK using the Morphie USB-C to Mini Display Port cable https://www.apple.com/shop/product/HN8B2ZM/A/mophie-usb-c-cable-with-mini-displayport-connector Sadly, it takes up one of the precious Thunderbolt ports on the 2020 Mac Mini (there are only two) and suitable USB-c hubs seem to be rare without adding unwanted extras. Consequently, I’ve maxed out by using the other to an external SSD drive, which is much quicker than any of the USB-A ports. It would be great if instead the iMac Target Display could be driven from the HDMI port that’s on the Mac Mini. Though Belkin do have an HDMI to Mini Display port cable, I haven’t been able to get it to work. However, every time one of them goes to sleep or I want to restart the Mac Mini, I have to disconnect the Morphie USB-C / Thunderbolt cable, re-establish the screen working on the iMac again, by gently pressing the power on button on the back and tapping the iMac keyboard (I haven’t worked out the correct or optimum combination of taps and clicks yet, it just seems to work eventually!) reconnect the Morphie cable back into the Mac Mini re-adjust the brightness again using the iMac keyboard all works happily again Adobe LightRoom and PhotoShop, Adobe RAW, and Capture One 21all work brilliantly well with almost seamless image rendering speeds. Things that DO NOT seem to be working OK are: the F2 button switching on the iMac — which I think would mean I wouldn’t have to keep dis- and re- connecting the cable from the port and must be impacting on their lifespan. the DisplayCal colour calibration profile which worked so well on the iMac fails miserably — maybe I’ll be able to re-calibrate when I find he spectro-Munki-Monaco-gizmo amongst all the piles of mess! Apart from all the displays not being allowed to ‘sleep’, everything appears to be running pretty cool :-) Does anyone have any ideas about bringing the HDMI port into action with the iMac, and or the reconnection issues?

thunderbolt port display I've got an A1407 Thunderbolt Display here at work and after I plug in the permanently attached thunderbolt cable to either of my Macbook Pros (Retina 15in Mid 2015 and Retina 13in Late 2013), the display flickers a few times and then turns completely black. It feels like it's the permanently attached thunderbolt cable that has a short in it. Is it possible to connect one of these Macbooks directly to the thunderbolt port on the back of the monitor? I don't know if that port is only for attaching additional devices or if you can connect it to a computer.
