DC500 4K Fuser

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 Drivers 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.

Drivers Update Compatibility
Units of the DC500 Fuser shipped before April 22, 2025, come with the older Drivers version. Users of these early batches can freely upgrade to the latest Drivers, which resolves most known bugs. If your device is working properly, updating is optional—you can upgrade anytime in the future.

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.
