lg 29um69g-b wide resolution problem.

[kostek]

Hello,

I have usb docking station UNITEK y-3704 with Displaylink adapter. I'm connecting it to my laptop (Thinkpad L570 on WIN10) via USB 3.0 and to Docking station I have connected 21:9 screen: LG 29um69g-b. I have installed latest drivers with DisplayLinkMenager (version: 9.3.3147.0)... However no matter what, I can't get resolution 2560x1080.

- I have checked in windows dispaly settings and I don't see any possibility to get this resolution.
- Like I was telling before I have updated drivers to latest version
- I was trying to force manual settings via: CRU_1.4.2
- Checked if any of described elements is not supporting such resolution (anwser: no)

All that for nothing... Also I was trying to use intel graphic menager, but displays connected via docking station are not visible there, I think cause PC think that DisplayLink is separate graphic card.

If it is possible, please give my advice, what can I do to get 2560x1080 resolution.
Many thanks in advance,
