DMS-59 to HDMI Adapter Cable — Split a 59-Pin Graphics Port to Two HDMI Displays

This DMS-59 (LFH-59) to HDMI adapter converts the compact 59-pin output found on selected professional and small-form-factor graphics cards into two HDMI ports, letting you connect modern monitors or TVs without bulky add-in hardware. It’s a clean, plug-and-play way to refresh legacy desktops at the office, power dual-screen dashboards, or extend an older workstation for presentations and training rooms—while keeping cable runs organized and low-profile.

DMS-59 (also known as LFH-59) carries two independent digital video channels from a single connector. With this adapter, you can map those channels to dual HDMI outputs and drive two displays from one slot. Because it’s a passive break-out, the final resolution and refresh depend on the graphics card and display capabilities; many setups comfortably support up to 1080p per monitor for office apps, signage, video playback and browser-based dashboards. The molded junction and flexible jacket keep routing tidy inside dense desks and meeting spaces.

Installation is easy: power down the PC, seat the DMS-59 male plug into the GPU, secure the thumbscrews if provided, and connect your HDMI cables to the adapter’s outputs. After boot, use your operating system or GPU control panel to arrange screens (mirror, extend, or single-display modes). For the most reliable handshake, attach the primary monitor to Output-A first, then add the second display—this helps legacy cards set EDID consistently.

The adapter shines in mixed-equipment environments—finance floors with legacy SFF PCs, retail back-office stations, school labs, or factory HMIs where you want HDMI screens without replacing older GPUs. If your card instead exposes analog pairs (some variants exist), you can still use HDMI displays with active converters, but for best results choose DMS-59 digital pairs → HDMI as provided here. Either way, label your HDMI leads and avoid overly tight bends to maintain a stable signal over time.
