recently purchased AK1 connected to my tv with hdmi. anytime i logout user or switch users my whole screen starts flashing approximately every second.
i found workaround to unplug and re-plug hdmi cable.
only way i have found to stop flashing is restart windows.
does anybody know a better cure for this annoying problem?

This problem has something to do with the monitor and HDMI cable.
Different brands of monitors or HDMI cables have different impedances.
Replace the monitor or HDMI cable to try to solve the problem.
