Dual monitor display - driver installed but...

2019-07-01, 10:47 AM



I have Lenovo L470 using Thinkpad Pro Dock. Two same monitors Acer S230 are plugged in, one on DVI a second one on VGA.
The same driver for both monitors was succesfully installed - if I open device manager - there are 2x Acer S230 assigned - look ok.

But the problem is that if I open Display Settings, on this level only the first one shows as S230 and the second one shows PnP.
However, if I open Properties -> Monitor -> the correct driver S230 appears... and not PnP as it shows on the basic screen... so the driver is assigned here and cannot change it really.

All I want anyway, is to be able to set up the same resolution on both monitors. But the second one showing as PnP (but S230 installed in detail) only allows up to 1280x1024. I also checked Pro Dock firmware and Intel Graphics - the latest versions of both of them are installed.

Thank you,

Hi TomasKrigler! Welcome to our forums community. If you're referring to the ThinkPad Pro Docking Station, part number: 40AH0135US. The Thinkpad L470 is not listed as a compatible device to the docking station. You can check it here: https://www.lenovo.com/us/en/accessories-and-monitors/top-tech/Pro-Dock-135-W-US/p/40AH0135US.
