有一台hdmi2.0的2K高刷显示器，连次世代主机是不是最高只能2K@60？

 36-bit capability is
mandatory for deep-color-compatible consumer electronic devices, with
48-bit capability being optional.[6](§6.2.4)


Jump
up^ Maximum
resolution is based on CVT-RB, which is a VESA standard for non-CRT-based displays.[118] Using CVT-RB 1920×1200p/60 Hz
would have a video bandwidth of 4.63 Gbit/s, 2560×1600p/60 Hz
would have a video bandwidth of 8.07 Gbit/s, 4096×2160p/30 Hz
would have a video bandwidth of 8.40 Gbit/s, and 4096×2160p/ Hz
would have a video bandwidth of 17.04 Gbit/s. All values include
TMDS 8b/10b encoding overhead.[119]
