Has anyone had issues with a hub to HDMI monitor, plugged mine in this morning and the external was flickering every few seconds. Had to switch to HDMI to Thunderbolt cable.

I only had this flicker problem with a imac i gutted out and converted to a monitor. I bought a power supply that didnt have a ground. It would only not flicker when i was touching it or had it touching my other imac. Just replaced it with a ground power supply. Issue gone. Doubt thats your issue if it was working before. Does your dock have a ground? If not maybe thats the issue. My thunderbolt 2 dock has a plug with a ground. If yours doesnt than maybe it was working before because it was touching something before providing it a ground.
