    This concerns an HP late-model notebook, Win7 Home Prem x64, used as a desktop with HDMI-connected 1080p 21", plus usb mouse/kbd. The goal is to make this as simple as possible: desktop-like. Just turn it on and work.
    It seems that either/both coming out of sleep state or simple shutdown and startup the Monitor stays offline because, I suppose, its getting no signal from the notebook. I tried to duplicate this on a dell notebook in my 'lab' but I only have a vga connect to work with - it just works. in fact I have trouble with the usb port but not with the monitor persisting.

    is there a chance there is some interplay between vendor/maker-specific implentations, plus perhaps the embedded Intel HD video controller?

    this could be an external device problem, somehow messing up allocation of resources @ boot. my brother has a new i7 super machine, hooked up with a monitor(dvi) and an hdmi bigsceen hooked up as well.
    no problems. then he hooked up a firewire card-hooked up to an external mixer, something like that. he had identical/very similar issues. when we troubleshot, i first said eliminate any possibilities no matter how remote.

    long story short.

    when the external device is powered up his main monitor did not work when coming out of hibernate mode. with it off(not the card just the devise) all is well.

    from what i could assertain, didn't sound like your problem. i know this sort of deal does not usually occur with printers and scanners. but it is somewhere to start(or end if nothing else is hooked up in such a fasion).

    good luck dude
