I bought a new 360 Elite about 2 weeks ago and was excited to hook it up using the HDMI connection. I currently have the 360 connected to my Samsung 61" TV with a Monster HDMI cable. When I try to power my Elite on with the Xbox controller sometimes nothing happens. The controller lights will blink, but the console never comes on. If that happens I have to power the 360 on by hitting the actual power button on the console and then when I do it takes about 20 seconds for the HDMI to kick in and send a signal to my TV.
The only problem is that when the 360 doesn't come on or it takes awhile to send a signal to my TV the Samsung won't recognize the HDMI input, it will skip over that input option because it doesn't detect a signal. So basically my TV inputs will go from HDMI 1 to Cable Channel 5 to Component 1 then Component 2. Well because of this the 360 never kicks in... it's like the 360 has to be on the HDMI input before it will turn on and display video.
So I have to change my TV back and forth from HDMI 1 to Cable and back several times before the HDMI 2 connection will pick up and the 360 will actually turn on and submit a signal. This needs to be address by Microsoft. I would think they could release a patch or firmware update for the HDMI connection. Does anyone else have this problem?
