CES this year was to visit with our friends at Gigabyte to see what they had to show off. Right off the bat we found an impressive 4K display configuration with four 1080p monitors.
Running off of Gigabyte's GA-Z77X-UP5TH dual-Thunderbolt motherboard, each of the ports was split using a Lenovo adapter, each connecting to a pair of the monitors on the quad-display stand. The result is a stunning 3840x2160 display configuration running completely off of the Intel HD 4000 graphics and the Core i7 processor.
