Signal reach and resolution

The Gefen EXTDVI141DLBP is a DVI-I extender that pushes dual-link digital video up to 200 feet from the source. It accepts two DVI-I 29-pin female connectors and draws 5 W from an external 5 V DC supply. The unit is built for installations where a single long cable run would otherwise degrade the picture.

Bandwidth and distance limits

Dual-link bandwidth reaches 2 x 165 MHz, supporting 3840 x 2400 at 30 Hz and 1080p at 120 Hz. The stock DVI specification caps reliable length at 15 feet; beyond that the TMDS signal loses integrity and sparkles appear. This booster equalises the video and DDC lines so the full resolution survives the full 200-foot run.

Upgrade from passive cable runs

It replaces any passive dual-link cable longer than 15 feet that shows artefacts or signal drop-out. The jump is worth it when the display must sit far from the computer and image quality cannot be compromised. It does not add new resolutions, convert signal types or support single-link-only sources.

Questions about this item

How do I decide between the single-link and dual-link versions of this extender?

This unit is a dual-link model that supports resolutions up to 3840 x 2400 at 60 Hz and 1080p at 120 Hz, so it covers both single-link and dual-link needs in one device.

Will I actually see 3840 x 2400 at 60 Hz on my monitor at the full 200-foot distance?

Yes, the booster equalises the TMDS signal and maintains dual-link bandwidth of 2 x 165 MHz across the full 200-foot run, delivering the stated resolution without sparkles.

What does the DVI-I 29-pin connector limit in practice?

The 29-pin DVI-I sockets carry digital-only dual-link signals, capping the link at 2 x 165 MHz pixel clock which defines the maximum 3840 x 2400 at 60 Hz throughput.
