I have four monitors configured as one desktop, they should never change
resolution.

Is the window for the app on the HDMI monitor? It may simply be that the
monitor is adapting to the size of the display desired. If the HDMI
monitor had been displaying 1920x1080 at 60Hz and the app wants 640x480
at 50Hz (I know, not likely but useful as an example), then the monitor
has to change its settings and may blank while it does so. Can it be
prevented? In such a case probably not--it's a function of the monitor,
not the display card or video drivers.

hdmi monitor blanks when starting some apps

2017-05-30 Thread DJ Delorie 

I have multiple monitors on my system, one of which is HDMI (the rest
are DP or DVI).  It's not the main monitor.  When I start some apps
(esp games), the HDMI monitor blanks for a few seconds until the app's
window comes up (not full screen).

Is this a normal thing?  Can it be prevented?
