Virtual Machine Based High-Resolution Display Wall: Experiments on Proof of Concept

Abstract

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.

Low-cost tiled display system architecture with dynamic web-based management

“…5 In this paper, implemented videowalls using one or few computers, each with several embedded graphic cards (with several outputs connected to different displays), are not considered. 6 Raspbian is a simplified version of Debian, designed to run under ARM processors. https://www.raspberrypi.org/downloads/raspbian/ (last access: July 2022 7 solution performs correctly and in a stable way, and that it is better than the one included in the previous prototype (based on the publicly available sync module, pyOmxSync).…”

“…However, these solutions present some limitations that must be considered, such as: the aforementioned high prices; the fact of only being able to be locally controlled and managed (i.e., physically close to the system); the difficulty for end users, who are very likely to be non-expert, to customize or extend these systems, for example, by adding more displays; or the perception, in some cases, of the videowall as a single display by the control software, preventing the system to play out different media contents simultaneously on different sections of the videowall. These limitations and the cost-effectiveness of multi-display environments are summarized in [6]. Some of the associated challenges to provide a successful experience with this type of system are also emphasized in that work, such as scalability, ease of configuration and seamless integration of the tiled display into the environment.…”
