Product overview
Dual-source overlay and switching
Dichen DC1A686 combines two computers' video on one monitor and can switch to the main or secondary source alone.
Display modes vary by revision
Supports 1080p, 2K, 4K and ultrawide modes. Some revisions are advertised at approximately 600 Hz at 1080p, 360 Hz at 2K and 160 Hz at 4K. These are revision-dependent claims, not a guarantee for every unit or display configuration.
Full DisplayPort connection
Three DisplayPort 1.4 ports connect the main computer, secondary computer and monitor. Supports monitor-information passthrough and EDID-related settings; consult the revision's manual.
Optional capture function
Capture-equipped revisions use the CAPTURE USB-C port to capture the original or combined video. Connect to USB 3.0 or faster. Confirm this function is included in the revision you purchase.
Display, controls and updates
On-screen information includes input mode, overlay status and temperature. Physical buttons adjust keying strength and display mode. The DATA USB-C port is for debugging and firmware updates; it is not required for everyday overlay.
Before ordering
High-refresh modes may require colour-format or custom-timing adjustments. Confirm the exact revision, ports, display modes and accessories before purchase.
