I wonder if you uninstall chrome and try reinstalling again would help..
Have you heard of chromecast , I stream movies to my big screen TV free... it is $35.00
I bought chromecast too. But then I bought a laptop with an HDMI port. So now I can use my Panasonic 65" plasma HDTV as a monitor, my 20" monitor and my 16" laptop monitor at the same time. And with windows 10 I can drag and drop pages from one monitor to another. And I have a wireless mouse and wireless keyboard.
So now the Chromecast dongle is obsolete.
