I bought this tv only a few months ago and it worked perfect on my old setup. (i5-3570k, asrock z77 extreme, 16gb ddr3, msi 1070ti) I just built a new setup about a week ago (ryzen 7 2700x, asus prime x470-pro, 16gb ddr4, msi 1070ti) and with this new build my tv keeps going to sleep randomly and waking back up about 10-15 seconds later. I have tried any and all settings, both on the tv and in windows, without any fix. I have also tried different hdmi cables and a dvi to hdmi cable and it didn't change anything. Also I have a second screen and it is also a Vizio but its not smart and it works fine, at this point I'm lost as what to do to stop it from going to sleep. Any advice or help would be great.
