I installed a new monitor and I connected it to my laptop, but I can't reach to DOCKY on secondary monitor, while on my laptop it is available.
Can docky be shown on every monitor?
I don't think you can have docky on both monitors. However, you can move it to the monitor where you want it. The site https://answers.launchpad.net/do/+question/60850 says:
