This paper presents the scalability and hardware dependency problems found in existing solutions in the high resolution display wall domain and proposes a new solution. Authors propose hosting the system that provides the visual content for the display wall inside a virtual machine. In such way any needed configuration of displays and resolutions can be applied to the graphics processing unit simulated by the virtualization system. The frame buffer content of the virtual graphics processing unit is then split, encoded with H.264 and sent over gigabit Ethernet as an RTP stream to the display wall. The display wall is driven by Raspberry Pi embedded devices that receive the stream, decode it and send digital video signal to the displays. This paper describes the construction of a prototype for this architecture and provides preliminary results that prove the potential of this solution.

Abstract. This paper provides scalability and use case analysis of a prototype for virtual machine based high-resolution display architecture. This architecture has been presented by the authors to overcome the reasons due to which other research results in the high-resolution display wall domain have still not achieved industrial success. Authors have provided use cases of this architecture with common operating systems like Linux and Windows and common software applications to demonstrate how a display wall solution can become seamless to the software layer while providing scalability, which is limited in the hardware-based display wall solutions that dominate the industry.
