After 10.10 upgrade, Bootcamp windows will no longer show on second screen (TV)

I have upgraded to 10.10.2 on my 2012, 13" Macbook Pro.

Before this, I could my use a HDMI cable via thunderbolt to have a multi-display with my LCD3207 TV. Now, this can only be achieved on the Mac side. Windows 7 Professional recognizes the attached TV, and windows can be dragged between the displays. However the TV simply reads "Not Support".

Any help would be appreciated, thanks.

MacBook Pro, OS X Yosemite (10.10.2), Windows 7 Professional

Are you using a TB/DisplayPort-to-HDMI cable to connect to the TV, or is there an DP-to-HDMI adapter also in the chain? Does Windows recognize the name of the monitor?

DisplayPort-to-HDMI cable, this one specifically http://www.amazon.co.uk/dp/B00EI41K26/ref=sr_ph?ie=UTF8&qid=1435686859&sr=1&keyw ords=kamor.

Windows recognizes the TV, down to the make. It's as if everything is functional, the other display still exists. Windows can still be dragged and placed onto the monitor from the Macbook. The only issue is a blue screen on the monitor and text claiming "Not Support"
