IOGear USB 3, HDMI extended monitors, MacOS High Sierra 10.13.6 Not Working
Hello friends,
I just purchased an IOGear dock GUD300 and connected two monitors via HDMI. One is HDMI to HDMI, the other is HDMI through DVI connector.
I connect from IOGear's USB3 connector into my Macbook Air which is currently in OS version High Sierra 10.13.6.
I downloaded and installed Displaylink V4.3, beta 5 driver. I made sure that the Displaylink User Agent is allowed to control my computer via the Security and Privacy setting of my Macbook.
I also connect a wireless logitech keyboard and mouse.
I made sure all the power is connected on monitors and the dock.
I connected my Macbook Air with IOGear dock via the USB3 cord.
This is what happens:
1. the screens detect a signal in HDMI
2. the screens then remain blank (a bit grey-er than the black screen when turned off or with no signal).
However, when I connect any one of the monitors directly into my MacBook Air via HDMI using my thunderbolt adapter, any one of these screens work.
Finding:
1. the monitors work individually when connected to the Macbook directly via thunderbolt HDMI adapter.
2. The wireless keyboard and mouse works.
3. The monitors detect a signal
Problem:
I don't see anything on the monitors.
I tried uninstalling the driver, and reinstalling. I even tried uninstalling the driver, and reinstalling 4.1.11 and this doesn't work.
Can you please help? I need it ASAP.
