Description

When my LG TV is connected to my 580 with HDR enabled, my PC has a little heart attack. As long as the display is static, the TV operates nominally. But when 4K content is pushed to the device, Windows displays mouse lag akin to high CPU usage, the picture will display but the bottom 30% of the TV will flicker white approx every 5-7 seconds (this also interrupts the audio) and then eventually I get 'snow' on the TV before the screen goes black. Disconnecting and reconnecting the HDMI solves the issue until it happens again.
