Hi Kai,

I guess you are using DP130 on a sink application or eDP application(otherwise, why no use link training?)
Yes for 4k2k@60Hz you need to select 5.4Gbps as data rate , 2.7Gbps is not enough for this resolution an refresh rate.

Dear Carcia

I am using DP130EVM to test ,I think EVM default setting is for Link Training
Due to I have no idea why DP130 can't work with 4k/2k ,so I will check DPCD register value firstly

Thanks
