You've got a Mini DisplayPort laptop and the projector in Room 3 is still VGA. Or the monitor next door only has DVI. You don't need three separate adapters. This one Lindy converter handles all three — HDMI, DVI, and VGA — from a single Mini DP source. Plug it in, pick the output you need, and you're presenting. No driver installs, no signal boosters, no 'have you tried restarting.' It's a small, tidy solution for the mixed-display rooms that still exist in most Australian offices, schools, and meeting spaces
