How To Enhance Museum Visual Experience with Immersive Projection Technology
How to create successful visual presentation?
Question: How do you define a successful visual presentation? 🤔
Our answer💡: Great content plus the right technology.
16th ~ 17th June, 2024, at CMMálaga, Culture & Museums International Tech Forum, we had the pleasure of being surrounded by incredible professionals from the ecosystem of the museum and culture industries. We consider our participation a resounding success.
GeoBox museum immersive projection solution
GeoBox streamlined the technical configurations, resulting in a stunning immersive visual experience. The content was carried by BrightSign XC5 series 8K players, processed by GeoBox M810 and G901 controllers, and displayed using 4 Panasonic MZ880 laser projectors with special 0.3 TR lenses.

Behind the scene...
Many customers asked us about the details of this solution, such as how to produce the content, how to arrange the signal source and resolution, and most importantly, which GeoBox models to choose. If you also have the same question, please read to the end, we will explain the unique strategy behind the GeoBox in this immersive projection system solution.
Note💡: For better understanding about all the technical detail, if you haven’t read the article A Comprehensive Guide to Content Preparation with GeoBox , we highly recommend to read it first.
Project requirement:
Need to project one content across three walls (width: 3.21m-7.54m-3.21m, height: 3m) using four projectors. The longer middle wall is projected by two projectors, and the walls on each side are each projected by one projector.
Step-by-step planning and system configuration:
- Decide content aspect ratio: To avoid image distortion, the playback content was prepared to match the final combined image’s aspect ratio, that is (3.21+7.54+3.21) : 3 = 13.96 : 3
- Decide source resolution: We decided to use WUXGA (1920×1200) resolution projectors. Considering an 20% overlap area between projector #2 and #3, the optimal resolution (horizontally) is 1,920×4 – 1,920x 0.2 = 7,296 pixels. Considering the content needs to be in the same ratio as the entire wall, which is 13.96:3, the content needs to be made in 5,584 x 1,200 pixels.
- Select proper playback device and arrange content for it: For better system reliability, we decided to use dedicated content playback device- BrightSign media player was used in this project. In order to reach the necessary system resolution which is >4K, the content was firstly split by BrightSign player into two 4K sources (A & B in the diagram) and sent to GeoBox front end processor (G901), which combined two 4K sources into one side-by-side signal in an customized 5584×1200@60hz resolution and output to M814. The M814 edge blending controller was used to crop the content for each projector including overlap region between projector 2 & 3 for edge blending. The M814 also controlled the geometric alignment (image warp) for all projectors and the edge blending for projector 2&3.
What makes GeoBox the easiest and handiest museum immersive projection solution for content creators and AV technicians?
- No more complicated content preparation process, no “pixel plan” needed:
GeoBox powerful geometric alignment feature allow you to reshape and combine multiple images to fit the target display area. GeoBox “Full screen” mode let the content fill up the entire outputs. Thus, as long as the content is created in the same aspect ratio as the combined display area, there will be no distortion in the final combined image, regardless of the source resolution. - Flexibly adapting to any input source device, real plug & play:
GeoBox support any content playback device and any input resolution, including non-standard resolution (such as ultra wide, or portrait…etc). Besides, once the configuration is set, you can switch content into any other source without further adjustment, GeoBox would intelligently maintain the immersive settings for your new moving arts!
