Got an i3-2310 Acer laptop - windows 10 Home 10.0.18363 - intel graphics 3000 - video bios 2119.0 - directx 11.0. - dell st220 monitor
Installed all latest drivers - and my problem is that I do not get an option to duplicate/mirror monitor - when using the dock - but do when i direct connect via hdmi laptop to monitor.
All other options extend/set 1/set 2 as primary all work fine through the dock - just no option to duplicate - under system settings.
Use Windows-P - all options appear - including duplicate at all times.
If hdmi cable is in docking station - select duplicate causes it just to extend - if hdmi cable in laptop - then it duplicates.
At a lose now - any idea what could be going wrong?
