Dear DylanJohn,
In our company we have the same problem with the exact same Thin Clients, I was hoping you could update me on your status.
We are working with a RDS server 2016 through a gateway connection. It is a local server connected trough a gigabit Lan connection.
All of the 10 thin clients have some screen artifacts. Two of them have it all the time.
Relogging does not help and we changed almost all settings with no succes of fixing it.
On Google I cant find much about this problem with this specific thin client.
Hope to hear from you soon,
Bram
