环境

电脑

  • MacBook Pro (Retina, 15-inch, Mid 2015)
  • 2.5 GHz Intel Core i7
  • 16 GB 1600 MHz DDR3
  • AMD Radeon R9 M370X 2 GB
  • Intel Iris Pro 1536 MB

MacBookPro2015的雷电口可以支持4k@60Hz, 这里要注意的是 HDMI口不支持4k@60hz,需要使用雷电/miniDP转DP的线。
miniDP与雷电口兼容。

显示器

  • Dell P2415Q

Dell P2415Q显示器最高支持3840x2160@60Hz(4k@60hz)。

这里需要注意的是需要关闭MST: Dell显示器 - 设置 - 菜单 - 显示 - MST - 关 。

MST选项的含义:

确认的DisplayPort(DP)配置的显示屏。
如果您的系统支持DP版本1.2,显示器可以显示的分辨率3840x2160@60Hz。 显示multi-stream传输(MST)应设置为"Off",这是默认状态。
MST关闭:(dp1.2模式的单个显示器设置)默认模式:4k*2K60Hz禁用MST功能。
MST主要:MST(dp1.2模式的菊花链式安装)功能已启用的主显示器菊花链式安装中。 预期的解决方案是4k*2K30Hz的MST(DP)已启用。
MST二级:(dp1.1的菊花链式和单个显示屏设置)MST功能被禁用的第二个显示器菊花链式安装中预期的解决方案是4k*2K30Hz的MST(DP)已禁用。
如果计算机支持DP版本1.1,显示器将无法实现3840x2160@60Hz。 它将支持较低60Hz的分辨率(如2560 x 1440或设为1920x1080。
通过显示器的屏上显示菜单(OSD)(屏上显示(OSD),请更改选项从MST"关闭"MST"二级"(要更改显示器的设置从DP1.2至1.1)。 Through the Monitor’s On-Screen Display menu (OSD), change the option from MST “OFF” to MST “Secondary” (You are changing the monitor’s setting from DP 1.2 to 1.1).
可能需要重新启动计算机显示器设置激活。
