modern VDAs. This is the only way to scale seamless sessions. Scaling might cause blurriness in the
images, particularly in the case of text. There can be poor performance when connecting to legacy
VDAs (6.5, or configured for Legacy Graphics). Local App Access, RTOP, and other plug‑ins that use
screen positioning APIs do not work with scaling. By design, seamless apps jumps between monitors
in this mode to maintain correct scaling.
This setting is recommended for users on Windows 10 connecting to modern VDAs. It supports mixed
DPI without any additional impact on server resources.
Unscaled:
The unscaled setting sends the full resolution of all monitors in the session. These resolutions are un‑
scaled and can result in small text and icons in apps and desktops. This corresponds to the UI setting
“No” and the HighDPI policy is set to Enabled in the GPO. This setting does not cause any blurriness
due to scaling, but can result in small text and icons. When connecting to a desktop session, the DPI
can be set within the VDA resulting in the desired scaling. This is not possible on RDS desktops, or
seamless applications. Enabling this setting causes sessions with higher resolution which can impact
server performance and scalability.
This setting is recommended for desktop sessions requiring the best image quality, where the addi‑
tional server resources are acceptable. It can also be used in cases where the small text and icons are
not an issue for the user.
Operating system scaling:
Operating system scaling is the default and corresponds to the UI setting “Let the operating system
scale the resolution”. The High DPI policy set to Disabled in this scenario. This lets the Windows Op‑
erating system handle the DPI scaling for a session. The resolution on the VDA is scaled based on
the DPI, resulting in a smaller resolution than the client device. This works well for single monitor
sessions, and is eicient when connecting to 6.5 VDAs, or VDAs configured for Legacy Graphics. This
method does not support Mixed DPI‑ all monitors must have the same DPI or the session does not
work. Scaling can cause blurriness in the images, particularly in the case of text. There might also be
issues with cursor sizes on Windows 10 Operating system.
This setting is recommended for users on Windows 7 endpoints, or those connecting to legacy VDAs.
It can also be used on Windows 10 if there is no Mixed DPI.
Virtual display layout
This feature lets you define a virtual monitor layout that applies to the remote desktop and to virtually
split a single client monitor into up to eight monitors on the remote desktop. You can configure the
virtual monitors on the Monitor Layout tab in the Desktop Viewer. There, you can draw horizontal
or vertical lines to separate the screen into virtual monitors. The screen is split according to specified
percentages of the client monitor resolution.
You can set a DPI for the virtual monitors that is used for DPI scaling or DPI matching. Aer applying a
