Dual Interface Upgrade · HDMI 2.1 + DP 1.4 · Ultra-High Frame Rate Fusing Solution The DICHEN DC500 4K Fuser is a high-performance video fusing device integrating both HDMI 2.1 and DP 1.4 interfaces.It has been updated with new firmware that supports over 95% of current displays with HDMI 2.1 and DP 1.4 interfaces. This upgrade delivers enhanced stability, broader compatibility, and superior high-frame-rate output with native image quality. Hardware and Build Quality * PCB board material is on par with RTX 4090-class components, ensuring top-tier electrical performance and long-term stability. * Equipped with original imported XILINX FPGA chips, offering excellent image processing capability. * Both top and bottom layers of the fused video are output at full native resolution with no compression. * In DP mode, although some ultra-high refresh rates run at 6-bit depth due to protocol limitations, our proprietary image processing ensures a visual output indistinguishable from 8-bit. * Dual-interface output is visually sharp and smooth, with true, unaltered frame rates.
