VDM Docs: Citrix VDI and Remote PC Support

Please note that VDM is supported on Windows 10/11 and Windows Server 2012/2012R2, 2016, 2019 and 2022. Evaluations can be downloaded here.

Virtual Display Manager supports Citrix VDI including both XenDesktop and XenApp deployments.

There are two installation types available:

  • Server-side, i.e. install on the target VDI instance (XenDesktop workstation or XenApp server)
  • Client-side, i.e. install VDM on supported endpoint device

Server-side installation does provide convenience of centralized image management with per user personalization and is prevalent with VDI deployments.

At the same time endpoint installation does have it’s own benefits and does not require any software installation on the server-side.

Starting with Windows 7 Microsoft introduced support of so-called “multi-headed” sessions where true multi-monitor support is offered to match client-side monitor configuration. Citrix VDI does take advantage of this functionality and assures that remote session is matched to the desktop topology set at the client. Because of one to one mapping of client-side configuration to session monitors, with this setup there is no possibility to offer multi-monitor benefits with only a single local monitor. This is where VDM installation at the endpoint machine can help – VDI can seamlessly instruct Citrix VDI session to support the number of virtual VDM displays as if they are true physical monitors.

Both server-side and client-side installation share the following benefits:

  • Save money with inexpensive endpoints – no physical multi-monitor support is mandatory for multi-headed sessions (although it is supported by VDM).
  • Conserve power by using a single high resolution monitor, while benefiting from multi-monitor support within the Citrix session.
  • Improve Citrix VDI scailability by conserving server-side session video buffer memory and thus allowing large number of VDI instances in Citrix environment while not discarding multi-monitor functionality.

Citrix Remote PC is a close cousin of Citrix VDI.

Here is a short clip on how VDM compliments Remote PC deployment targeting physical remote PCs:
