Hi, I just purchased a HP monitor and Chromecast, I want to connect my Chromecast to the monitor as well as the laptop, but there's only one HDMI port on the monitor. I want to minimise the amount of cables if I can. Maybe a dumb question but what does the USB B USB A cable actually do when connected from laptop to monitor? Thought I could use this cable to free up the HDMI port, any ideas? Thx guys.
