DP159 能够支持的data rate 在数据手册中有解释，8bit 色深能达到4K60：The SNx5DP159 device supports data rate up to 6-Gbps per data lane to support Ultra HD (4K × 2K / 60-Hz) 8-bits per color high-resolution video and HDTV with 16-bit color depth at 1080p (1920 × 1080 / 60-Hz)。
可以看出， intel 是32bit，那么根据total data rate 去进行计算看是否超过DP159能够支持的最大data rate。
Total data rate = [# active horizontal pixels + horizontal blanking] x [# active vertical lines + vertical blanking] x [frame rate] x [# bits/pixel]
Dell的是8bit 色深，所以是符合datasheet 4K60， 8bit的分辨率要求。
这个bit depth 是无法进行更改的。
