Windows Server 2019 and RemoteApps - "The number of local display monitors exceeds the limit allowed by the remote computer" error

Hello -

I am getting a strange error when I attempt to access an application via RemoteApps. The error is "The number of local display monitors exceeds the limit allowed by the remote computer."

I have 6 monitors. The RemoteApps server has the display limit set to the default of 16. I am running Server 2019 as my desktop and the RemoteApps server is also running Server 2019. For all my Googlefu, I've not been able to find much about this specific error.

First, I'm assuming that the RemoteApps display limit is for all concurrent connections? Is this accurate? If this is the case, it would make sense that my 6 monitors put us over the 16 screen limit, as my co-workers that use this RemoteApps server all have multiple screens.

Second, can the display limit for RemoteApps be increased from 16?

Any advice is appreciated. Thanks.
