Use VM full screen on second monitor, leaving OS X on main?

Hello all, first post. I love Parallels 11, my iMac is strong enough I can run games at full graphic settings with no issues at all, which is amazing on a VM. I've not gone and gotten and HDMI cable so the second monitor is my TV, I would like to put the VM windows 10 on that full screen but leave my OS X running on the iMac screen as that is what I use and only use windows for gaming. I've been unsuccessful at figuring out and researching here and online for a way, either it full screens on my iMac, or it full screens on both, I have no way to force windows to only be on the second screen, even if i choose this option in windows it remains on both and logging in and out won't change it. it gives an unable to make changes error. Please if there is anyway to do this my setup would be complete!!
