Hi all.

I bought this new television today, and I love it so far, but the thing at the moment that is bothering me is the HDMI inputs don't switch automatically when turning each piece of equipment on. The Sky box is on HDMI1, a pc on HDMI 3 and an xbox360 on HDMI 4. 

I've just got rid of an old bravia kdl-40u2000 and I had a 3 way switch plugged into the back of this due to this television only having 1 HDMI port. Now the new tv has 4, I thought this would be easy but no, I have to manually switch the AV input. Am I missing something very simple, or does this option just not exist. 

Thanks in advance for your help
