Signal distribution

The Gefen EXT-DVI-142DLN splits one dual-link DVI source to two dual-link DVI outputs for simultaneous display on two screens. It accepts single-link resolutions up to 1920 x 1200 and dual-link up to 3840 x 2400. Auto EQ compensates for signal imperfections. HDCP pass-through is provided on output one.

Sustained operation

The unit draws power from an included 5V DC supply to maintain stable dual-link bandwidth across both outputs during continuous use. Cascading multiple 142 units extends the distribution chain without degrading the amplified signal. Front-panel DVI Link indicators confirm active connections on each port.

DVI interface limits

Dual-link DVI bandwidth caps the maximum resolution at 3840 x 2400, so higher pixel counts cannot be transmitted. Single-link sources are limited to 1920 x 1200 regardless of display capability. The DDWG standard ensures compatibility with compliant monitors, but newer digital interfaces are not supported.

Questions about this item

Does the Gefen EXT-DVI-142DLN generate noticeable heat or fan noise when powered on all day?

The unit has no fan and draws power from an external 5 V DC supply, so it runs silently with minimal warmth during continuous use.

Which cables and power items must I already have to connect a PC and two monitors to this splitter?

You need one dual-link DVI cable from the source to the input, two dual-link DVI cables to the displays, and a nearby mains socket for the included 5 V DC adapter.

Will the EXT-DVI-142DLN pass a 1920 x 1200 single-link signal from an older graphics card to both screens without downscaling?

Yes, the splitter supports single-link resolutions up to 1920 x 1200 and duplicates that signal to both dual-link outputs at native resolution.
