How to play a movie through my Surface Pro 3's HDMI out port

How do I tell Windows Media Player to play on the screen connected to my HDMI port?

My TV (a 5 year old Samsung 46") won't let me select the HDMI port (#3) until it detects there's a signal on it and for some reason, my Surface won't recognize the external monitor.

It's almost like a chicken and egg situation.

The TV has 3 HDMI ports. One is connected to a PlayStation 3 which works as expected.

Any help would be appreciated.

Sounds as if you need a 3 port hdmi switch so that you select a different port the one your desktop should appear on, then when you play a video on any media player in full screen it will appear on that HDMI port. You switch to the playstation.
Each HDMI connection has a different port, like the AVS1 AVS2
Otherwise take the PlayStation out and replace with cable from laptop then in control panel display settings enable the 2ndary screen TV.
There is also sequence to this
Shut down the computer.
Turn off the monitor or TV.
Connect an HDMI cable to the computer and to the display TV
Turn on the display, and select the HDMI input as the input source to view.
Turn on the computer.
Open your playback devices from the sound icon>On the Playback tab, click one of the following, if present:
NVIDIA High Definition Audio
ATI High Definition Audio
Realtek HDMI Output
try holding down the function (Fn) key and tapping the blue monitor key (it's different on all laptops, but usually one of the "F" keys) to send a digital signal to the TV?

I decided to not fiddle with it since it works on a number of other more modern TV's and I didn't want to "break it".
