I am having problems with my TV as a monitor. When restarting my computer from both completely off and sleep sometimes the computer comes on but the TV just sits and says no signal available. I've found that if I hold the power button and turn it off that way then turn it back on the TV suddenly starts working. Any ideas on why this might be happening and how to fix it?

GPU is a Nvidia GTX 960 going through an HDMI.
 
When two HDMI devices are connected they "handshake" with each other to establish a connection. If your PC is not booted up at the time the TV is looking for this handshake it stops looking. Turning the TV off then on makes it look for the handshake again. Changing the input and back again should also work. This is normal and I don't think there is a way to fix it other than turning things on in the correct order.

I tried this and it still doesn't connect. I also tried pulling the HDMI from each end and plugging it back in to reestablish connection and still nothing.
