Hi everyone,
I’m reaching out because I’m having an issue with my DisplayPort setup, and after trying multiple fixes, I’m running out of ideas. Maybe someone here has faced something similar and can help.
Here’s the situation:
I use both a Windows PC and a work MacBook (macOS). I have three external monitors — two connected via HDMI and one via DisplayPort. My goal is to use all three monitors with my MacBook when working, and with my PC when gaming.
To achieve this, I set up:
• A hub station for my MacBook
• Two HDMI switches
• One DisplayPort switch
Each switch has one output (connected to a monitor) and two inputs — one from the PC and one from the hub station.
When I want to switch between devices, I simply power on the hub station, and the switches automatically detect and switch to the MacBook’s output.
Everything works perfectly with the HDMI monitors, but I’m running into a problem with the DisplayPort monitor.
Here’s what happens:
• Switching from Mac → Windows: Works flawlessly. All screens connect instantly.
• Switching from Windows → Mac: The DisplayPort monitor stays black and shows “No source signal.”
Interestingly, macOS still detects the monitor — it appears in Display settings, and I can even adjust its parameters — but nothing is displayed.
The only workaround I’ve found is to turn the monitor off and on again, or to disable and re-enable it in DisplayLink Manager.
This is frustrating because the whole purpose of my setup was to avoid manual steps every time I switch devices.
I suspect the issue might be related to EDID (Extended Display Identification Data) — maybe the DisplayPort doesn’t reinitialize the EDID handshake when switching from PC to Mac. I’ve looked into EDID emulators as a possible fix, but since they’re quite expensive, I’d like to confirm if that would actually solve the issue before investing in one.
Has anyone experienced something similar or found a reliable solution?
Thanks in advance for any help or advice!
Regards,
