Absolutely not! I can't stand TVs and projectors that try to be too smart with inputs. If you're the TV, you don't know that I'm about to plug my computer in and I've selected the input before connecting it. Otherwise I'll plug my computer in first and it's also trying to be too smart and can't see any TV connected so it doesn't set up the multimonitors properly. So no, they really shouldn't try to ignore unconnected HDMI inputs. I used to have an old style TV that ignored the RGB input it there was no audio signal with it. So to use it as a computer monitor, I had to plug in an extra audio cable for no good reason.
