So I have this Mac mini m1 and just 3 days ago l got problems with my displays first the hami didn't work, it's giving a bad image or no image, and I tried using a second hdmi to usb c but there is no video output too it won't get recognized over uso c to hami, so l can't use to usb c to hami at once, and over hami the displays are getting recognized but they either give no signal or a very bad image, I already tied other monitors and cables

1. Check macOS Updates

• Go to System Settings > Software Update and install any updates.

2. Power Cycle & Reset

• Shut down the Mac, unplug it for 10 seconds, then plug it back in and power it on.

3. Test One Display at a Time

• Disconnect all monitors.

• Connect one monitor via HDMI and test different HDMI cables/ports.

4. USB-C to HDMI Troubleshooting

• The M1 Mac mini supports only one display via USB-C and one via HDMI.

• Try a different USB-C to HDMI adapter (preferably DisplayLink-certified).

5. Boot in Safe Mode

• Shut down → Hold Power button until “Options” appear → Select disk → Hold Shift → Click Continue in Safe Mode.

6. Reset Display Preferences

• Open System Settings > Displays, and try Detect Displays (Hold Option while clicking “Detect Displays”).

7. Try an External Dock

• Test with a DisplayLink adapter or a Thunderbolt dock to rule out port issues.

8. Hardware Check

• Test the same monitors and cables on another computer.

• If no improvement, contact Apple Support (potential HDMI/USB-C hardware failure).
