Low Force Helix (LFH) is a 60-pin electrical connector (4 rows of 15 pins) with signals for 2 digital and analog connectors.
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 unuseable without an adapter.
Using the LFH interface requires a graphics card with multi-monitor capabilities and an LFH port. Currently, NVIDIA and BFG Technologies manufacture such cards.
Another application of LFH capabilities is manufactured by Matrox. The Matrox card outputs via two LFH cables to a single monitor, delivering 9.2 million pixels of resolution (3840 x 2400). This system provides large amounts of detailed information for professional applications such as aerospace and automotive visualization, computer aided design, desktop publishing, digital photography, life sciences, mapping, oil and gas exploration, plant design and management, satellite imaging, space exploration, and transportation and logistics.
The LFH connector is present as a serial interface on Cisco 1000 series routers.
