I bought the “Plugable USB 3.0 Dual 4K HDMI 2.0 Adapter with Gigabit Ethernet” product. The problem is that about once per week, the display goes blank and the monitor shows an on-screen message saying “no input detected”. In other words, it acts as though there is nothing plugged into it at all. (This will often happen complete out of the blue when I am not even using the computer, but I see the signal drop from across the room.)
The ONLY way to fix this is to reboot the computer. Simply unplugging the HDMI cable from the adapter (or the adapter’s cable from my laptop’s USB 3.0 port) and then replugging it does not work. Which doesn’t make much sense…suggests that something within the firmware is getting corrupted. I have the latest DisplayLinka drivers installed.
Any ideas what’s going on?
