[已解决]无法使用3840x2160分辨率的60赫兹

布丁酱 · 2021-03-28 17:33:46

如题所示，新购入一个27寸的显示器，发现3840x2160分辨率只有30赫兹及一下可以选择，没有60赫兹选项，但是如果是1920x1080则可以选择60赫兹。我怀疑此情况与显卡支持有关，请大佬讲解

根据intel的显卡规格说明，该显卡的HDMI接口不支持 4k@60，请用DP接口。

请确认你的显示输出接口/线材是否支持4K/60hz。具体来说需要HDMI 2.0或者DP1.2

matrikslee · 2021-03-28 19:17:14

HDMI1.4 只能支持到4k30或者4k60 Y420 8bit，需要4k60 RGB或者Y444 8bit请用DP或者HDMI2.0

HDMI2.0需要两边接口和线材均满足要求带宽才可以
