Elitebook 840 G5, Can this support two external 4k monitors?

[rsstnnr]

1. Can the G5 Elitebook drive the internal 4k screen AND two external 4k monitors @60Hz? 

2. Assuming the G5 is capable of three 4k screens @60Hz (including the internal) which dock can support two 4k 60Hz monitors? Presently I have the slimline dock which I have read is limited to dual 4k monitors at 30Hz.

Question about this table. So if this laptop has HDMI port and USB-C in witch you can plug dock station so it should support up to 3 monitors (one it's own and two external) in every case? Right?

I started to dig into this becouse when I received this laptop I could plug monitor via HDMI but when I tried to plug second external monitor via USB-C I failed. I did it with USB - C extension with HDMI, USB 3.0 and USB-C as output.

So the real question is - does USB-C in this model support video transfer? If yes then it should support 3 monitors (2+1), if not then USB-C docking station shouldn't work?

Does the laptop support dual 4k @ 60hz output from laptop's HDMI and USB-C ports?

I can only get up to 4k@60hz + 2.5K@60hz

also I have the ultraslim docking station and trying to get dual 2.5k @ 60hz to work without any luck.

best I can do is 2.5K @ 60hz and 1080@60Hz or 2 x 2.5K @30hz (both connected to DP)

I updated all the driver for the mu 840G5
