"Integrated graphics are underpowered for 3D gaming (see: IGP-vs-IGP Benchmarks later in ths review) but well suited to regular office-type desktop work with one or more monitors (see: IGP-PCMark Vantage Benchmarks). The integrated graphics outputs on the Gigabyte GA-Z77X-UD3H support HDMI at 1920x1200 pixels, DisplayPort at resolutions up to 2560x1600, DVI-D at 1920x1200 and Analog VGA. This board can handle dual digital displays with Sandy Bridge CPUs or triple displays for Ivy Bridge CPUs."
Hope this helps.
