    Hello,

    I’d like ask the owners of Asus B850 & X870E motherboards if they can get 4K with 120hz 10bit color via onboard HDMI port.

    Official specs say up to 4K 60hz but there are some users that can get 4K 120hz with x670e boards: https://forum.level1techs.com/t/ryz...ors-hdr-full-range-rgb-via-motherboard/212084

    I own a Ryzen 8700G with powerful onboard graphics and a 4K 120hz TV (4xHDMI 2.1 only).
    I’d like to buy an Asus board and get that refresh rate via HDMI 2.1, without a dGPU.

    So anyone that has achieved that resolution and which mobo ?

    Thanks
