Hello, I come to you today looking for a fix to a problem I've been trying to solve. I work in a school district and some of our staff have Google Pixel Slates as their device and recently 2 different people had the same issue, their slate would not connect to a tv over USB-C to HDMI. The device will either connect but the picture will be all glitchy with this weird rainbow effect or the tv won't be detected at all. I've tried multiple tvs with multiple cables and multiple Slates and yet the issue persists. Googling the issue hasn't gotten me anywhere either. Any help would be appreciated. Thank you.
