I believe that many friends who do large-screen splicing will encounter this problem. How to improve the clarity of the screen so that it can achieve point-to-point resolution display?
We know that the resolution of an LCD screen is 1920*1080, that is, when each screen displays a single image, each pixel corresponds to a physical pixel on the screen. In this way, our visual experience is very clear. If one pixel of our image corresponds to multiple pixels on the physical screen, the effect will appear blurred and stretched. The visual experience given is that the clarity is not enough.
Normally, for a 3*6 video wall, the whole screen will be 1920*1080, which means that the pixel of one image is presented by 18 liquid crystal molecules, which does not achieve the point-to-point effect. If the output resolution given by our computer is 3840*2160, then the pixel of each image is presented by 9 physical screen pixels, so the clarity will be twice as high as 1920*1080.
For example, if the resolution of our computer output is 3820*2160, and our LCD splicing wall is a 2*2 splicing wall, then one pixel of each image corresponds to one pixel of the actual physical screen. We call this situation point-to-point display, and the clarity is excellent.
So how do we achieve point-to-point display when there are a large number of screens and the combined size of the screens is relatively large?
Then our computer signal needs to give 8 groups of 4K signals to our multi-screen image processor. The configuration of the multi-screen image processor must be 8-way 4K signal input and 32-way 1920*1080 output. In this way, the whole screen splicing effect can achieve point-to-point processing.
This is achieved in a point-to-point manner through a multi-screen image processor.
You can also use the Multi-Screen Treasure Box to achieve this point-to-point method. The principle is the same. Divide the output resolution into corresponding equal parts. Each output resolution of the computer is guaranteed to be 3840*2160 pixels. In this way, there are 8 outputs, connected to 8 input interfaces of the Multi-Screen Treasure Box, and the output interface of the Multi-Screen Treasure Box is connected to 32 screens. The combined full-screen image is displayed point-to-point.
There are also computers that output a signal source with a very large resolution, which is given to a high-end signal processor, which is processed internally by the processor into 32 1920*1080 output signals to the screen, which can also achieve the effect of point-to-point processing. This has very high requirements on the processor.
Different processing methods require different signal processing equipment. We need to analyze it specifically based on the specific screen presentation effect. However, the basic principle is the same, which is to divide the resolution of the computer signal into smaller modules to display the pixels of each screen.
