Setup:
- OEM deck charger plugged into PD port on dock
- Built-in USB cable from dock plugged into deck
- HDMI cable running from dock to Viewsonic VA1655-FHD portable monitor
- Samsung charging brick with USB-C plugged into monitor for power (works with everything else)
- Monitor is recognized in desktop mode but no video is displayed on the monitor
- Power cycling monitor doesn’t do anything except reset it and then show the “no signal” message
Troubleshooting steps/findings
- Taking the dock out of the equation by running deck charger to USB-C on monitor, then USB-C from monitor to deck works fine. Power routes through monitor and charges the deck, too.
- Monitor works with a different USB dock plugged into my phone with the same HDMI cable plugged into the dock and the monitor.
- I don’t have a DP cable to test a different monitor.
Any more troubleshooting ideas? I can’t think of any other ways to reconfigure things without
