Budget Computing: Nine H55 And H57 Motherboards Compared
By

Home theater builders will be happy to see that every motherboard in today’s comparison supports combined video and audio signals using either HDMI or DisplayPort, while a dual-display output capability is a boon to office users. Yet none of these platforms are capable of providing dual-link DVI, so users who require 2560x1600 pixels of desktop space on a single display will likely need to add a video card.
