===== From April 24, 2018: =====


If an image from one of the projectors appears to be blinking and the 3D output does not look right (looks double for instance while rest of projectors look fine), then do this:

Use the master remote control to switch inputs on all of the projectors
Plug in the master remote control and type:

ADDR 00    (select all of the projectors)
HDMI INPUT (switch input to HDMI, which is not connected)
DVI INPUT  (switch input back to DVI, which is how all are connected)

===== From call with Wes on June 13, 2018: =====

Today we had an issue with a blinking projector.  Within the past 2 weeks there have been some power outages, so that is a possible factor.  We tried restarting the render node, and didn't fix it.  We tried going to Nvidia settings > Workstation > Synchronize Displays and switching the timing server to "on another system" and back, and that didn't fix.  The blinking stopped when in the Synchronize Displays menu, we selected on another system other than "mosaic displays" as the timing server.  The displays all report a refresh rate of 59.999Hz.  For now, that seems work.
