Q: flickering screen while in clamshell mode - mac book air

I have a new Mac Book Air and a new HDMI LG External monitor.   In clamshell mode about every 15 minutes the screen will flicker unrecognizably for 10-15 seconds and then work normal again.  There are a lot of posts with this same issue but I don't see any resolution.  Can anyone suggest a permanent fix?

MacBook Air, iOS 8.4, clamshell mode
