My TV takes a fraction of a second to pull up the list of connected devices (a few HDMI devices), and about 3 seconds to sync once you selct a HDMI device ... it doesn't wait 7 seconds per device while you're polling your HDMI ports. At any rate, my TV can assign either a predetermined, or a custom NAME to each input, so I don't need to poll each input to work out which device I'm watching.
If my TV took 7 seconds to sync, and I had to synch to every device to figure out which device was which every time I switched, I'd scream blue murder
Most TV's have 2, 3 or 4 HDMI inputs, and a few component/composite/other crappy non-digital signal inputs?
A good thing nonetheless.
A great thing would just to piss off HDCP altogether, but that's not going to happen anytime soon, is it?
