W530, External monitor flashes on OpenGL

I have a Lenovo W530, which I'm using with an external ASUS monitor connected via HDMI. When I launch an application that uses OpenGL, all of my screens flicker off and on multiple times for about 2 or 3 seconds all told, and then finally stop flashing and then it works. However, I would prefer that it did not do this, because it is very annoying.

 

Without the 2nd display connected, the laptop screen works fine and doesn't flash. If I connect a different 2nd ASUS monitor via VGA cable, it also works fine.

 

I did not have this problem until upgrading video drivers recently to deal with another unrelated issue (a different piece of software required updated NVidia drivers).

Any ideas?
