Q: Extra desktop appears on login
I have an iMac, with a TV connected as an extra screen. This is set up in Sys Prefs > Displays as a second screen, with no mirroring.
I have 6 desktops in Mission Control.
Whenever I log in, a new desktop is created. If I don't delete it, it will still be there next time I log in, plus yet another new one. Sometimes I have ended up with half a dozen extra desktops ('cos I forgot to delete them earlier).
??? what is this about?
It's nuisance value only, but I do wish I didn't have to keep deleting unwanted desktops.
OS Yosemite (10.10.5)

After some discussion with an Apple rep, I have finally decided that it is probably a handshake issue, since the TV and the imac are connected via an HDMI cable.
The new desktop that is created is a copy of the desktop on the TV, and the issue only happens when the computer is starting up..
I occasionally have a handshake issue between the DVD player and the TV, and I suspect that this is what is also happening here.
