P2720DC, USB Type-C, Daisy Chain resolution

Hello everyone,

I have tried to find an answer in the forum and was also reading the FAQ; USB Type-C monitors FAQ

I'm interested in the new P2720DC and P2720D. If I understand the difference between the two types correctly, the
DC version is a USB Type-C capable monitor.

I would set it up like the following, with daisy chaining:

Laptop (HP EliteBook X360 1030 G2) -- USB C --> P2720DC -- DP --> P2720D

For the last (second screen) the D model should be fine, since I don't consider expanding any further. At the  first screen (DC model) mouse and keyboard shall be hooked too. And the laptop shall be charged with the monitors power delivery (PD) functionality. Which means, only one USB Type-C cable is plugged on the laptop.

The question which I could not answer for myself is, if my proposed monitor setup would allow, driving both monitor with 2560x1440 resolution? Since this depends on the High Bit Rate (HBR2 vs. HBR3) standard if only USB Type-C is used and not Thunderbolt 3. I fear it will not be possible with my laptop. These are some data regarding the laptop:

  • HP EliteBook X360 1030 G2
  • Intel Core i7-7600U CPU @ 2.80GHz
  • Intel HD Graphics 620

I guess my proposed setup will not work and I would have to use a Thunderbolt 3 dock and drive the two screens via DP cables. This means, I need one additional hardware unit (docking station). 

Thanks for our help,
