Limit maximum display resolution This policy setting allows you to specify the maximum display resolution that can be used by each monitor used to display a Remote Desktop Services session. Limiting the resolution used to display a remote session can improve connection performance, particularly over slow links, and reduce server load. If you enable this policy setting, you must specify a resolution width and height. The resolution specified will be the maximum resolution that can be used by each monitor used to display a Remote Desktop Services session. If you disable or do not configure this policy setting, the maximum resolution that can be used by each monitor to display a Remote Desktop Services session will be determined by the values specified on the Display Settings tab in the Remote Desktop Session Host Configuration tool.
