Desktop won't connect to TV via HDMI

[jamelhoud]

Hi there all, my desktop connects to my monitor just fine via HDMI, I go to connect my TV and nothing happens. I got the desktop for Christmas and my old laptop connected fine with the TV. I only have one HDMI port on my desktop. My graphics card is an AMD R9 270. I am using Windows 8 My the keyboard that came with the HP computer lacks (for some reason) an fn key, I read that pressing the fn and f4 key while the TV is plugged in switches the output device. Obviously I can't try this so I am really beat, and confused as to why this doesn't work. When i turn on my desktop, initially I see the HP logo and spinning loading wheel as the desktop turns on. I see this on the TV. after it has loaded nothing happens on the TV. (So when it gets to the login screen the output stops). I am really stuck so please please help.

what size is the tv?

1080p monitor & 720p TV ??
Only thing I can think of that would cause this.

you may have to use a different cable to connect to your tv, i cant figure out what the issue is tho

Most likely you just need to change the input port from the TV's menu. You might also need to switch the TV to PC mode.

In the TV menu there is no menu to do such a thing (PC mode)

Suggest restarting in safe mode then plugging HDMI quickly from monitor to TV if possible while its booting.
Having no function keys is not helping here.

It seems like a refresh rate incompatibility or something to me.

What is your current refresh rate set to in display settings??

Tried dropping resolution to 1280x720 (720p) on your monitor then powering off & restarting on TV??
Bit lost - it has to be some sort of hdcp handshaking issue .
Doesn't explain you getting the starting windows display ok though.
