With X-plane 11 my Cessna screen comes up dark except for the nav-com/ gps units

Question

The outside scenery is fine, but all the normal instruments and controls are unreadable because they are so dark — x-plane 10 is ok on the same PC

Answer 1

There are dials on the panel to the left of the throttle that adjust the lighting. Is this a problem in the day light as well as at night? If so, there is something else going on. A screenshot would probably provide the most information since the info here is pretty limited.
