The DC1A255-H3 is a hardware fuser from DICHEN built on three HDMI 2.0 ports. It merges the picture of two computers onto one monitor: the signal travels over the cable, at hardware level, with no software layer and nothing to configure.

Resolutions and refresh rates

  • 1920×1080 — up to 240 Hz;
  • 2560×1440 (2K) — up to 144 Hz;
  • 3K — up to 100 Hz.

Colour is 8-bit, colour modes are supported, and the low-level exchange is complete.

What it does

  • Native EDID passthrough. The monitor reports its own capabilities; nothing needs substituting.
  • One-button switching. Two computers on one monitor, a button on the case between them, no cables to swap.
  • Direct hardware signal path. The full low-level set: DDC, HDCP, TMDS, CEC, HPD, SCL, SDA, EDID.
  • No setup. No drivers, no utilities, no configuration files.

Where the manufacturer contradicts itself

Two figures are stated differently on DICHEN’s product page and in their own comparison table. Both versions are printed here rather than whichever is more flattering:

  • 2K. The page says up to 144 Hz, the comparison table says 120 Hz. On 1080p the two agree on 240 Hz.
  • One-press EDID editing. Claimed on the page, marked absent for this model in the table — it is the senior DC1A686-D3ZC that has it.

If the purchase hinges on either point, write to support before ordering and we will confirm it with the supplier for the specific batch.

The gap in price is a gap in bandwidth, not in build quality: on a 1080p 240 Hz or 2K 144 Hz monitor the senior models simply have nothing left to do.

Who it suits

This is the working minimum for 1080p and 2K: multi-display office setups, 144–240 Hz gaming builds, and benches with professional or engineering equipment. For a faster monitor or for 4K, look at the DC505 and the DC1A686-D3ZC.

Versions and colours

The manufacturer makes a Deluxe and a Standard; Standard is unavailable at the moment. Colours are DICHEN Gold, Patriot Red and Sincere White, with Loyal Silver and Rock Black temporarily out. Confirm the version and colour when you order.

Which fuser your monitor actually needs

The choice is decided by the monitor’s input and refresh rate, not by the model number. The DC1A255-H3 covers HDMI 2.0: 1080p to 240 Hz and 2K to 144 Hz, which is where most gaming monitors live. For 4K or higher rates you want the DC505 (4K, with capture built in) or the DC1A686-D3ZC on DisplayPort 1.4 (1080p 639 Hz, 2K 364 Hz).

Check before ordering

  • The monitor’s input. HDMI 2.0 or newer.
  • The panel’s refresh rate. A fuser preserves it rather than raising it.
  • The second computer. It needs an HDMI output — usually a Mini PC.
  • Cables. Three ports, three HDMI cables rated for the rate you want.

What people buy alongside it

A fuser works as part of a chain: a DMA card reads memory, a mouse-control module handles input, and the second computer is usually a Mini PC. Ready-made sets are in kits.
