I bought 3 USB2.0 display adapters and installed one and it worked. I shut down the laptop as there was a windows update and after this all I get is a flickering arrow on the laptop screen. I tired another USB device, another cable and the same result. The green light does not even come on. I tried to reinstall the driver but I am not able to as it says it is up to date.
I am so very disappointed.
Can you help?
