You can use external keyboards, external displays, microphones, and other external devices with remote desktops and applications in Horizon Client. Monitors and Screen ResolutionYou can extend a remote desktop to multiple monitors. If you have a high-resolution monitor, you can see the remote desktop or application in full resolution. Supported Multiple Monitor ConfigurationsHorizon Client supports the following multiple monitor configurations. Connect USB Devices with USB RedirectionYou can use locally attached USB devices, such as thumb flash drives, cameras, and printers, from a remote desktop. This feature is called USB redirection. Using ScannersWith the scanner redirection feature, you can scan information into remote desktops and applications with scanners that are connected to the local client system. This feature redirects scanning data with a significantly lower bandwidth than can be achieved by using USB redirection. Using the Real-Time Audio-Video Feature for Webcams and MicrophonesWith the Real-Time Audio-Video feature, you can use the local client system's webcam or microphone on a remote desktop. Real-Time Audio-Video is compatible with standard conferencing applications and browser-based video applications, and supports standard webcams, audio USB devices, and analog audio input. Using Serial Port RedirectionWith serial port redirection, you can redirect locally connected, serial (COM) ports such as built-in RS232 ports or USB-to-serial adapters. Devices such as printers, bar code readers, and other serial devices can be connected to these ports and used in the remote desktops. Using the Relative Mouse Feature for CAD and 3D ApplicationsIf you use the VMware Blast display protocol or the PCoIP display protocol when using CAD or 3D applications in a remote desktop, mouse performance improves when you enable the relative mouse feature.
