Detailed description:I used to work with external monitor plugged via thunderbolt. I left for holiday and after two weeks on my return the monitor does not recieve signal from the laptop. The monitor itself is working fine with my other HP laptop and macbook air. Thunderbolt does not seem to work it does not recognise external ssd or flash drives. My asus util diagnostics did not find any isses. I have tried to remove thunderbolt controller from device manager and reinstall it, tried to download and install thunderbolt drivers again - nothing works.
