It equates to the lowest resolution resulting from the whole system: from signal source, controller, transmission devices like connectors and cables, all the way to projectors.I use GrandVJ almost daily and despite being completely enamored overall with the software, I occasionally notice certain things that I feel could use some refinement/improvement.ДЎ. System resolution isnвЂ™t just about your projector or source resolution. To summarize, depending on the viewing distance and expected image size, we know how big the pixel pitch should be, then we can decide the first important factor: system resolution. HereвЂ™s an example: if the viewing distance is 5 metres and the image size is 20 metres wide, then in order to achieve a 5mm pixel pitch, system resolution needs to be at least 4K вЂ“ and that means the whole system needs to support a resolution of 4K or above.

Pixel pitch is calculated by dividing the image size with its resolution. In our experience, when watching from a distance of one metre, the pixel pitch needs to be equal or less than 1mm. ThatвЂ™s why the pixel pitch of outdoor LED walls can be quite big, but still looks fine from far away. The closer the viewing distance, the smaller pixel pitch it has to be.

More and more people tend to use projectors without such functions but do it through standalone solution, which can be either edge blending software (need to run on PC) or edge blending controller box. Regarding above #3 and #4 points, you can use projectors with built-in вЂњedge blendingвЂќ and вЂњgeometric adjustmentвЂќ functions (for example, some high end Epson or Panasonic projectors), but they are usually quite pricy. A solution to geometrically adjust each projected image.A solution to seamlessly blend projected images at the edge.Besides, itвЂ™s not necessarily more expensive, and even cheaper considering future maintenance cost.

In short, with hardware image controller, you can utilize any input source, and you can keep the whole system simple and robust without worrying about compatibility issue of PC or itвЂ™s operating system. Please click here for the detail about this topic. You can choose to play the image from PC with multiple output graphic, however, if you donвЂ™t want to play source from PC, for example, media player or live stream from digital camera, aВ hardware image controller (or so-called video wall controller) is a much better solution in terms of stability, flexibility and ease of use.

If you want to scale single image to multiple projectors, itвЂ™s necessary that the image has to be divided into multiple pieces. The capability to crop content into multiple pieces and distribute them to each projector.WeвЂ™ll dive into this part in below paragraph of вЂњHow to decide spec and quantity of projectorвЂќ. In this article, we want to touch base on all the essentials you need and planning tips if you want to perfectly edge blend multiple projectors: WeвЂ™ve talked about the detail of what to consider and the pros & cons of each different type of solutions in the previous article: How to plan for large projection system. You can choose projectors featured of warping and edge blending function, or use external solution- hardware or PC software, to combining projected images from multiple projectors. By combining and and warping images from multiple projectors, you can create projection on a larger and even irregular surfaces.
