You know, a statement like "it's the limit since the admin guide says so" is completely unacceptable.
I don't know why this should be a limit (it's neither a limit of RDP or a current version of Guacamole). Maybe it was with Guacamole 0.9.9 (which is about 2 years old!) which still seems to be used in this product. A little update to that part certainly wouldn't hurt...
just found this thread. KB stated here is not available, there is other one "HTML5 Known issues"
where we can see:
|KB40470||Resolution size behavior with HTML5 Access||Working as designed|
reference to same article which is not available and in fact refers back to KB40305..
my question is - does we have any changes on this in 2020? is it possible to enable auto-resize to browser tab size which works fine in guacamole. is there some settings tunes for that, as 1920x1080 looks "a bit" outdated.
I would avoid using Pulse now for this. Their support for HTML5 is subpar with constant disconnects and poor quality.
Just deploy Guacamole itself. Youll have a much better time
