Kind Reminder:
The 4K Fuser needs to be scheduled for production at the DICHEN factory. Delivery typically takes 7–10 days after you place your order. Thank you for your patience and understanding!
The latest version of the DC500 4K Fuser comes in black. The previous gold color version is an older model and has been discontinued.
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.
🔄 Firmware Update Compatibility
Units of the DC500 Fuser shipped before April 22, 2025, come with the older firmware version. Users of these early batches can freely upgrade to the latest firmware, 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.
HDMI 2.1 Version Specifications
* Supported Resolutions & Refresh Rates:
— 1920×1080P @ 540Hz
— 2560×1440P @ 355Hz
— 3840×2160P @ 158Hz
— Fully backward compatible; supports ultrawide monitors.
* GPU Recommendations:
— Nvidia GTX 3060 or AMD RX 6500XT
— Monitor must support full-bandwidth HDMI 2.1 FRL (48Gbps)
— Recommended secondary PC CPU: 6 threads or higher
DP 1.4 Version Specifications
* Supported Resolutions & Refresh Rates:
— 1920×1080P @ 480Hz
— 2560×1440P @ 320Hz
— 3840×2160P @ 160Hz
— Backward compatible with lower refresh rates; ultrawide supported.
* GPU Requirements:
— Both host and secondary PCs must have Nvidia 10 series or newer, or AMD RX500 series or newer GPUs

Extreme Performance Benchmarks
DC500 has been successfully tested to support:
— 4K @ 144Hz
— 2K @ 300Hz
— 1080P @ 480Hz
With AMD 6000 series or newer GPUs, the fuser can reach:
— 4K @ 160Hz
— 2K @ 360Hz
— 1080P @ 600Hz
(Note: Nvidia cards are limited by enforced DSC compression protocols, which may prevent reaching maximum refresh rates. This is a GPU-side restriction, not a fuser issue.)

FAQ:
Q1: Does the DC500 support 3440x1440 ultrawide monitors? Has anyone tested it?
A1: Yep, according to the specs, the DC500 supports 3440x1440 @100Hz over HDMI, which is good enough for most people. Most users are using a 3440x1440 ultrawide myself, locked it to 100Hz, and it works fine—no compatibility issues so far. Still, I’d recommend checking with technical expert just to be safe.
Q2: How much does the DC500 cost now? Has the price gone up?
A2: Yeah, it’s gone up. When I got mine, it was under $500, but now it’s around $500. That said, it’s still a solid choice if you’ve got the budget—especially with the latest firmware update that bumped 4K support up to 160Hz. Pretty future-proof if you ask me.
Q3: Does the DC500 support HDMI 2.1, or is it only DP 1.4?
A3: It supports HDMI 2.1, but a lot of people still use DP 1.4 depending on what their monitor supports. If your monitor only has HDMI 2.0, the DC500 works well with HDMI. Just keep in mind, with DP 1.4, you might be limited to 6-bit color in some modes compared to standard 8-bit on HDMI. Whether you can actually notice the difference is debatable though.
Q4: If I buy it from a Taobao store in China, what’s the price? Can they help ship it to users worldwide?
A4: Yes, the Taobao store is also the official DICHEN store. The price there is 3600 RMB, which is approximately $510 USD, but it does not include shipping. You’ll need to find a third-party forwarding service yourself to have the product delivered to your country. Additionally, you will have to pay extra service fees and international shipping costs separately.
