I am running Ubuntu (elementary OS) connected to a normal monitor which works fine. I am now trying to connect it to a TV through HDMI port, but the TV is unable get any signal. Please help me out.
Output of: sudo lshw -C display
*-display description: VGA compatible controller product: RS780L [Radeon 3000] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 5 bus info: pci@0000:01:05.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm msi vga_controller bus_master cap_list rom configuration: driver=radeon latency=0 resources: irq:18 memory:d0000000-dfffffff ioport:d000(size=256) memory:feaf0000-feafffff memory:fe900000-fe9fffff
Output of xrandr:

xrandr does not show HDMI at all. Is this a problem?
