My google-fu is weak
My docking station has a display port output. My monitor has DVI and HDMI inputs (but no display port)
My assumption that a display port to hdmi, or display port to DVI cable would make it all work seems to be flawed - tried both, neither works. HDMI out from the laptop works, but seems to defeat the purpose of the docking station!
Is my dock broken, have I got the wrong sort of cable, or have I missed a setting somewhere?
Lenovo Onelink+ dock, Benq GL2460, Thinkpad 13 / Win 10 if any of that is important
checking out via the screen options in win 10?
Docking software up to date?
Most likely the dock.
How do you connect to the doc - by USB ? There may be a driver issue (i.e. not installed) A DVI to HDM should work (that's what my some uses, a mix of HDMI to HDMI, DVI to HDMI etc as he has 3 monitors, so uses most of the outputs on his graphics card.
You have 'toggled' the screen output ?
Check display settings too - use duplicate first to check the lot is working
you lot are quick, thanks
Dock has it's own special connector (a onelink port according to lenovo). Dock driver and windows up to date.
Attempting to duplicate output gives a 'no display detected' message.
I think thattthr cables only work one way, DP monitor, DVI dock. May be wrong, can't remember which way it is.

Going from a DP port on the laptop to a HDMI monitor should work, it's going from HDMI to not-HDMI that can be tricksy.

The OneLink uses a proprietary connector I believe. If you're connecting it via USB, that's why it doesn't work. You need a driver also.

EDIT: sorry, I missed the reply where you've said this is all fine. Hmm. Get on to Lenovo support maybe? It could just be broken?
have you powered the dock?
do any ports in the dock work (usb)?
Eg some lenovo docks have a bigger psu than the normal laptop one to power more stuff
Further thanks to all.
Since writing I have double checked firmware and drivers - Cougar's link was where I think I did this when I first set up the dock, and both said 'you are already up to date'
Power - good point DaveP. 90W supply (came with dock), vs 40W on the laptop - swapped and got an error message about low power. USB and network all behaving as expected, just the display ports (two of them: neither works).
I did have a DP-HDMI, and swapped if for DP-DVI (thinking it was the cable). Same symptoms (display not detected). The dock has only DP outs. Monitor works with HDMI-HDMI. I don't have another DP source to test with unfortunately.
It's not one of those directional cable things is it? I thought that was just for HiFi buffs?
Lenovo forum suggests drivers, but I think I've addressed that. Have logged a ticket.
