While modern graphics processing units, including integrated graphics processors, support 4K resolutions, not all graphics cards and mainboards can actually output such high resolutions since they need a special output configurations. Gigabyte Technology this week demonstrated how its mainboards with two independent Thunderbolt connectors can support output with 4K resolution.


Modern 4K monitors and HDTVs use multiple signal inputs to transfer vast amounts of visual data from graphics processors, which is why two outputs are needed to support resolutions like 4096*2160 or 3840*2160. As the first motherboards to be certified by Intel featuring dual Thunderbolt ports, Gigabyte’s TH models offer up to 10Gb/s data transfer speed and one DisplayPort 1.1 (with support for 2K resolutions from each port) stream per port, which results in 4K resolution support by two ports.

Testing was successfully carried out at Gigabyte’s regional facility in Tokyo, Japan with the Eizo FDH3601 high resolution (4096*2160) color monitor that is designed for air traffic control and geophysical services. The setup was based on Gigabyte GA-Z77MX-D3H TH mainboard with latest official BIOS (F5 BIOS), Intel Core i7 3770K with HD4000 graphics, Windows 8 operating system with default drivers as well as two mini DisplayPort to DisplayPort adapters.


“Desktop PC motherboards are all about cutting edge features, performance, and upgradeability, and this is why Gigabyte was the first motherboard company to adopt dual Thunderbolt ports instead of the single port option. When combined with other innovative products, such as Eizo’s 4K resolution FDH3601 monitor, Gigabyte Thunderbolt motherboard users can enjoy next generation display options with their existing platform, without having to wait for future 4K resolution standards,” said Tim Handley, deputy director of motherboard marketing at Gigabyte.
