The Gigabyte Z77-HD4 supports the latest Intel Ivy Bridge processors as well as previous generation Sandy Bridge CPUs. The Gigabyte Z77-HD4 straddles the line between mainstream and entry-level segments. On one hand, the Gigabyte Z77-HD4 is priced lower than most ATX Z77 motherboards but it has flexible integrated graphics options in the form of HDMI and DisplayPort outputs in addition to the DVI and D-SUB outputs in the rear I/O. Unlike most entry-level mainboards, the Z77-HD4 carries the Ultra Durable 4 stamp from Gigabyte, meaning it is comprised of high quality components including glass-fabric PCB, solid Japanese capacitors, ESD resistant ICs and Lower RDS(on) MOSFETs. The Z77-HD4’s glass fabric PCB design protects against electrical shorts caused by humidity over time, while better components ensure higher temperature and voltage tolerances, therefore resulting in a longer lifespan for the mainboard. The Z77-HD4 also comes with dual UEFI BIOS which allows the system to recover immediately should anything happen to the main BIOS. The Gigabyte Z77-HD4 comes with a 3-year warranty.
