Andrew bought a new MacBook Pro with the Vega 20 graphics and i9 processor. He hooked it up to an external monitor and the display is flickering. This is the top of the line laptop he paid $4,200 for. What's wrong? Leo says Andrew should take it to Apple to look at it, because it sounds like a hardware issue. He returned it and got a replacement, and the new one is flickering as well. Leo says to change cables and change displays. Eliminate all the easy things. Unfortunately, since even happens on the laptop's screen, Andrew really needs to take it back to Apple and have them fix it.
