Description

Three video outputs without a graphics card

The rear panel has HDMI 2.1 and two DisplayPort 2.1 outputs with HDCP 2.3 support and a maximum resolution of 4096 × 2160, so monitors connect straight to the processor graphics. The BIOS offers a multi-theme interface, AIO fan control and Q-Flash Auto Scan, while AI Perfdrive provides ready-made tuning profiles. The VRM is a hybrid 4+1+2 phase design.

Who this motherboard is for

Builders of an office or home PC who rely on Intel Core Ultra integrated graphics and want to connect more than one monitor. Four memory slots, two M.2 slots and two PCIe x1 slots leave room to expand later; there is no Wi-Fi on the board.
