[SOLVED] How can I redirect my computer's display screen to TV through HDMI in Porteus?

I want to use TV screen as the display(the output device) of my PC. I had a HDMI output from my PC and HDMI input in TV screen and cable. Although I connected them by cable, I do not know how to start communication between them. How can I do it?

Hi hope,
1.) connect with HDMI cable

2.) two commands on terminal
pactl set-card-profile 0 output:hdmi-stereo
xrandr --auto

With pactl, the sound is redirected to the TV
With xrandr the screen resolution

worked for me

Thanks Kulle! Also I found an easier way that uses menu GUI that comes with standard Porteus installation:
1. Connect HDMI tcable to both TV and oPC
2. Open Preferences from Porteus menu
3. Open "Monitor and Display settings"
4. If your PC and HDMI device correctly see each other (i.e. graphics card driver, xrandr etc.) you will see two devices as in seperate monitors and you can choose HDMI output by simply ticking a checkbox left of it
5. Then you may need adjust screen resolution and refresh rate to correct values(you can check them with xrandr command in terminal window).

Kulle, could you please explain your code more before I try? What does your code do? What is "0", "output:hdmi-stereo" ? I do not want to lose my working audio system :unknown:
