The HP DisplayPort Port Flex IO v2 (13L54AA) is a small internal port module that adds an extra DisplayPort video output to HP business desktops that have a Flex IO bay on the rear panel. HP's Flex IO system lets an IT department choose which extra port a PC gets, so a machine can be fitted with a second or third display output later instead of being replaced. The module is a compact circuit board with a black DisplayPort bracket that slots into the Flex IO opening and connects to the motherboard. It measures 41.8 x 39 x 16.5 mm and weighs about 11.5 g. HP lists it as compatible with the EliteDesk 800 G6 (tower, SFF and Desktop Mini), EliteDesk 805 G6 SFF and DM, ProDesk 600 G6 (MT, SFF, DM), ProDesk 400/480 G7 MT, ProDesk 400 G6 DM, ProDesk 400 G7 SFF and ProDesk 405 G6 (MT, SFF, DM). Check that your exact model has a Flex IO v2 slot before ordering. One module is supplied; no cable is included.
