Feature:1. [DMA Fuser] Used to optimize the efficiency of data transfer and processing, mainly for high bandwidth data transfer and processing scenarios, such as image processing, video encoding and decoding, network communication, etc.2. [2 Signal Input] The DMA fuser supports 2 way signal input, allowing output on a single display by overlay, the overlaid image quality can be adjusted for clarity.3. [Adaptive Resolution] The fuser supports switching between single screens for complete display, the resolution is up to 2K 144hz, no need to debug resolution, no need for EDID debugging, which is adaptive.4. [Easy to Use] The DMA combiner ensures clear image quality, providing lossless transfer, which has built in fan for temperature control heat dissipation, simple to operate, plug and display.5. [Wide Application] Suitable for securities trading floors, banking data centers, traffic safety emergency control centers, and video conferences.Specification:Item Type: DMA FuserMaterial: Aluminum AlloyInterface:1.
