Hi Community, I have dual Hp z30i Monitors connected to ThinkPad Lenovo T490 docking station both display-display port, but it just provides recommended resolution in one screen and the other does not appear more resolution options the max just 1280x768 and this displays lack of quality, already upgraded display adaptors still not solved, please i seek advise from you.

Regards,

I don't know your dock, what is your T490, does it have NVIDIA MX250 2GB card or only Integrated Intel UHD Graphics ?

Now you wish to connect to two 2560 x 1600 resolution monitors. You can work this out number of pixels your machine can support two 2560 x 1600 monitors are too much dots therefore your machine can only show full on one screen and less on other screen. You need better graphics card on your computer.

Hope this makes sense.

Regards.
