Some screens are blank

[DvD123]

Some screens go blank. Sometimes they work on startup but after some time they just go blank. I'm using veyon just to monitor my students work. The only way to fix it is to go into the Veyon configurator for the individual computer, stop and start the veyon service again. But I'd like to not have to do that everytime. Thanks!!

@dvd123 have you tried refreshing it in the veyon master? maybe the units that got blank have its sleep mode enabled.
