I have iMac 5k 27'', 65'' UHD tv from samsung, and 4th Apple tv.

I tried to do mirroring my iMac to tv through apple tv but no screen comes out. The sound works well but no picture, just black screen.

Two ways to see your Mac on your big screen:
OS X Yosemite: Use your TV as a display < seems to require "wired" connection, just like any external display
Use AirPlay to display video from your Mac on an HDTV - Apple Support < this has a "Help section"

Once you initiate the Airplay, open display preferences and you will get 2 separate settings panels. Make sure the panel marked for the ATV is set to optimize for ATV and not iMac.
