title: Unsupported signal error connecting Raspberry PI to a HDMI port at Sony Bravia
body: <p>I bought a Raspberry PI and connected to one of my Sony Bravia's HDMI port. I got <code>unsupported signal, check your device output</code> error. I have another TV, another model of Sony Bravia, that TV can display Raspberry PI's output. My first TV support video signals of 1080i, 720p, 1080p and display resolution is 1366 x 768. I looked for the similar problems and some people complain HDMI cable problem. But not sure, it is cable problem. I think it is setting problem. Is there any setting in Raspberry PI for HDMI output.</p>
