NOTE: Some Windows RDP servers will not send RemoteFX content to thin clients enabled for RDP 7.1 without a change to Group Policy. Check the setting of the following policy: Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Remote Session Environment > Enable RemoteFX encoding for RemoteFX clients designed for Windows Server 2008 R2 SP1 In addition, Windows Server 2012 and Windows Server 2012 R2 require the following setting to be set to 32bit: Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Remote Session Environment > Limit maximum color depth Using multi-monitor sessions with RDP True multi-monitor support does not require special configuration. The RDP client automatically identifies which monitor is specified as the primary monitor in the local settings and places the taskbar and desktop icons on that monitor. When a window is maximized within the remote session, the window will only cover the monitor it was maximized on. Display preferences and monitor resolutions can be viewed but not modified within the remote session. To modify the session resolution, log out of the session and change the resolution on the local thin client. By default, all RDP sessions will be full-screen and cover all monitors to enhance the virtualization experience. Additional window options are available in the RDP Connection Manager. NOTE: Remote Desktop Virtualization Host (RDVH) sessions with graphics card support might only support certain resolutions and counts of monitors. The limits are specified when the RemoteFX virtual graphics device is configured for the RDVH virtual machine. Using multimedia redirection with RDP Multimedia redirection (MMR) is a technology that integrates with Windows Media Player on the remote host and streams the encoded media to the RDP client instead of playing it on the remote host and re-encoding it via RDP. This technology reduces the server load and network traffic, and greatly improves the multimedia experience, supporting 24 fps playback of 1080p videos with automatic audio syncing. MMR is enabled by default. The RDP client will negotiate with any RDP server it contacts, and if MMR is available, it will be used. MMR also uses an advanced codec detection scheme that identifies whether the thin client supports the codec being requested by the remote host before attempting to redirect it. The result is that only supported codecs will be redirected and all unsupported codecs fall back to server-side rendering. To disable MMR on the thin client for all RDP connections, set the following registry key to 0: root/ConnectionType/freerdp/general/enableMMR Because RemoteFX already delivers acceptable multimedia performance, you can disable MMR with RFX by setting the following registry key to 1: root/ConnectionType/freerdp/connections//disableMMRwithRFX TIP: For simplified management, HP recommends that MMR be enabled or disabled on the remote host.

Using multi-monitor sessions with RDP

True multi-monitor support does not require special

conﬁguration.

The RDP client automatically

identiﬁes

which monitor is

speciﬁed

as the primary monitor in the local settings and places the taskbar and desktop

icons on that monitor. When a window is maximized within the remote session, the window will only cover the

monitor it was maximized on.

Display preferences and monitor resolutions can be viewed but not

modiﬁed

within the remote session. To

modify the session resolution, log out of the session and change the resolution on the local thin client.

By default, all RDP sessions will be full-screen and cover all monitors to enhance the virtualization

experience. Additional window options are available in the RDP Connection Manager.

NOTE:

Remote Desktop Virtualization Host (RDVH) sessions with graphics card support might only support

certain resolutions and counts of monitors. The limits are

speciﬁed

when the RemoteFX virtual graphics

device is

conﬁgured

for the RDVH virtual machine.

Using multimedia redirection with RDP

Multimedia redirection (MMR) is a technology that integrates with Windows Media Player on the remote host

and streams the encoded media to the RDP client instead of playing it on the remote host and re-encoding it

via RDP. This technology reduces the server load and network

traﬃc,

and greatly improves the multimedia

experience, supporting 24 fps playback of 1080p videos with automatic audio syncing. MMR is enabled by

default. The RDP client will negotiate with any RDP server it contacts, and if MMR is available, it will be used.

MMR also uses an advanced codec detection scheme that

identiﬁes

whether the thin client supports the codec

being requested by the remote host before attempting to redirect it. The result is that only supported codecs

will be redirected and all unsupported codecs fall back to server-side rendering.

To disable MMR on the thin client for all RDP connections, set the following registry key to 0:

root/ConnectionType/freerdp/general/enableMMR

Because RemoteFX already delivers acceptable multimedia performance, you can disable MMR with RFX by

setting the following registry key to 1:

root/ConnectionType/freerdp/connections/<UUID>/disableMMRwithRFX

TIP:

For

simpliﬁed

management, HP recommends that MMR be enabled or disabled on the remote host.
