4.4.2 - Downgrade options? CRASHES Master and Clients, No Demo
-
My understanding is \\.\DISPLAY2, \\.\DISPLAY3 and \\.\DISPLAY4 are device names representing display output or screens.
In Clone mode screens and monitors could pair as;
\\.\DISPLAY1\Monitor0
\\.\DISPLAY1\Monitor1where one screen is applied to two logical monitor devices.
In Extended mode screens and monitors could pair as;
\\.\DISPLAY1\Monitor0
\\.\DISPLAY2\Monitor0where two screens are applied to one logical monitor device.
You can think of \\.\DISPLAY1 and \\.\DISPLAY2 as the output of the graphics card drivers/interface (screens) while \\.\DISPLAY1\Monitor0 and \\.\DISPLAY1\Monitor1 represent the attached monitors.
Two Nirsoft utilities, ControlMyMonitor and MultiMonitorTool, provide screen, monitor and adapter information with both GUI and command line control.

https://www.nirsoft.net/utils/multimonitortool-x64.zip
Extract both using the 7-Zip utility, https://www.7-zip.org/download.html, and for convenience place the extracted files into the C:\Windows folder.
Command line:
C:\Windows\MultiMonitorTool.exe /stext "C:\Users\Public\Desktop\monitorinfo.txt"C:\Windows\ControlMyMonitor.exe /smonitors "C:\Users\Public\Desktop\monitorinfo2.txt"
Question: Do any of the three monitors have touchscreens?

I’m not familiar with Veyon throughput or whether this is configurable. Generally I haven’t experienced performance issues using either Fullscreen demo or Window demo and though deselecting unused computers would achieve a modest performance gain my experience has been this doesn’t work very well on the fly. Since you are down to two lists I think it would be best to exit and restart Veyon whenever your selections change.

@DrewLoker the screen arrangement issue should be fixed in 4.5.3 - can you please test this version?
-
Ok, testing now. Installing on Master.
EDIT: Initially, it appears to be working...but no students in the room and I only logged in to one computer. But getting excited!!!
Does this need to be deployed to all clients urgently?
Thanks!

Well, it worked for a second on the one computer...but then client crashed...and did not work again. It came up with the "Establishing connection..." msg, but would not establish.When the next class came in, the computers were locked up and had to be rebooted. 25 of the 26 computers are still on 4.5.2. So, only the one client and the master are at 4.5.3. I am not sure I want to install across the entire unless you think it will help.
Will it make any difference if I install across the entire lab?

Demo still doesn't work.I brought the whole lab up to 4.5.4.0
It went to Demo, showed my screen for a few second on a couple of the 7 students logged in a lab of 26 clients. Then, Demo stopped working even on the couple that did get my screen.
I was able to back out of Demo mode with out crashing their computer.
