You cannot change the resolution of the remote desktop window if an administrator has locked the guest
size or if you are using the RDP display protocol. In these cases, the resolution tooltip shows the initial
resolution.
Use Display Scaling
Users that have poor eyesight or high-resolution screens, such as a 4K monitors, generally have scaling
enabled by setting the DPI (Dots Per Inch) on the client machine to greater than 100 percent. With the
Display Scaling feature, remote desktops and applications support the client machine's scaling setting
and appear normal-sized rather than very small.
Horizon Client saves the display scaling setting for each remote desktop separately. For published
applications, the display scaling setting applies to all published applications that are available to the
currently logged-in user. The display scaling setting appears, even if the DPI setting is 100 percent on the
client machine.
Note An administrator can hide the display scaling setting.
In a multiple-monitor setup, using display scaling does not affect the number of monitors and the
maximum resolutions that Horizon Client supports. When display scaling is allowed and in effect, scaling
is based on the DPI setting of the primary monitor.
This procedure describes how to enable the Display Scaling feature before you connect to a remote
desktop or application. You can enable the Display Scaling feature after you connect to a remote desktop
by selecting Options > Allow Display Scaling.
Procedure
1 Start Horizon Client and connect to a server.
2 In the desktop and application selection window, right-click the remote desktop or application and
select Settings.
3 Select the Allow display scaling check box.
4 Click Apply to save your changes.
5 Click OK to close the dialog box.
Using DPI Synchronization
The DPI Synchronization feature ensures that the DPI setting in a remote session matches the client
machine's DPI setting. When you start a new remote session, Horizon Agent sets the DPI value in the
session to match the DPI value of the client machine.
The DPI Synchronization feature cannot change the DPI setting for active remote sessions. If you
reconnect to an existing remote session, the Display Scaling feature scales the remote desktop or
application appropriately.
The DPI Synchronization feature is enabled by default. A Horizon administrator can disable the DPI
synchronization feature.
