New Plugable dock user but experienced IT guy. I am coming from using an Anker ethernet/hdmi/usb-c dongle that has never exhibited any of the symptoms I am seeing.
My laptop is an HP Envy X360 with Ryzen 4700U chip, so I am using a USB-C connection. My issues are…
my external HDMI connect monitor (LG 32" 2560x1440) does not remain connected when plugged into the Display 1 port. It randomly disconnects and goes black. I get a “beep” notification when this happens and I have to power cycle the monitor to get it to display an image again. This does not happen when it is plugged into Display 2 port.
the ethernet port does not always stay at gb speed. It will sometimes fall back to 100mb without notice. Sometime this happens after the laptop comes out of sleep mode, sometimes when the computer is first started. Doing a disable/enable cycle for the adapter usually brings back the gb ethernet speed. In case it matters, I am never connected to WiFi at the same time I use the ethernet connection.
I have also experienced what appears to be a lock-up of the dock on more than one occasion. I had to power cycle the dock to re-gain communications. The only items plugged into the dock are a transmitter for a Logitech wireless keyboard/mouse, the Plugable power brick, the usb-c cable (rear panel plug), the HDMI monitor, and ethernet cable.
Do you think I have a defective unit? Or am I missing something in the set up?
Thanks in advance.
