LFH

LFH may refer to:

Low-force helix

A low-force helix (LFH) is a 60-pin electrical connector (four rows of 15 pins) with signals for two digital and analog connectors. Each of the pins, visible in the photograph, is twisted approximately 45 degrees between the tip and the white plastic frame which holds all the pins. Hence "helix" in the name.

The LFH connector is typically used with workstations, because it can connect a single computer graphics source to up to four different monitors. The standard interface is a 60-pin LFH connector with two breakout VGA or DVI cables. This system provides users with flexibility for a variety of display configurations, though forsakes standard DVI or VGA connectors. This renders the LFH connector unusable without an adapter.

It's also used in HDCI (High Definition Camera Interface) used in Polycom HDX video conferencing systems.

Using the LFH interface requires a graphics card with multi-monitor capabilities and an LFH port. Currently, NVIDIA, Matrox and BFG Technologies manufacture such cards.
