Sep 6, 2016 12:36 AMby lllaass,Did it work before?
What specific hub?
Do other ports (if there are any) work on the hub?
Does the hub and monitor/TV show in System Profiler/System Information?

It is this hub http://www.aliexpress.com/item/Adroit-2016-New-USB-Type-C-to-HDMI-With-Charging- Adapter-USB-C-to-HDMI-Hub/32701498811.ht…
Other ports on the hub are working fine, no problem.
I can see the monitor in System Information, but I don't see the hub here. Is this the problem?

- Did you do this?
(For MacBook, click the gear-shaped “setting” > click “Display” > in the “Arrangement” mode, choose “Mirror Display” > choose the display resolution > enjoy!

- Try resetting the SMC and NVRAM/PRAM

- If you do not have a backup use disk utility to restore the internal disk to an external disk so you can try to recover data.
Then format the startup disk and do a fresh install of OSX
