On my gateway it goes through a cycle of functions so if it doesn't show you the whole desktop when plugging it in just keep on pressing that key combination and it should cycle you to the full desktop.

    Did you post the exact model number and make? I'll go ahead and look it up and see if I can download the user manual

    I am guessing you have a Ati Radeon video card in that laptop. If so then you should be able to go into your display options in the control panel and select change resolution and select 'extend the displays' or you should be able to select display 1 or display 2 if the laptop picked up the tv via the hdmi cable. Bear in mind I am saying this because I have a radeon video card in my desktop computer and I can select either of the options and they always work for me... maybe the HP Pavillion works different. I am only offering my opinion with my experience with radeon video cards ok.

    The screen is going black but is still there. Also the charms that are brought up turn EVERYTHING black. My main display is still on the laptop, but it's like the back light went off. Any ideas here? The problem is, for some reason, the light in my screen is going out. However I can very faintly see the screen. Thank you!

    I am not familiar with that laptop but was just thinking about it and was wondering is there a setting in your bios settings to change the output display? Worth looking into the settings and see if there is one then maybe it can be changed from its default. Possible on that laptop its either laptop screen or hdmi output and not both.
    Sorry you are not having any luck there

    It might be your screen resolution is too big. I usually connect my PC to my HDTV and it worked perfectly! Use WinKey + P then you can just scroll Up/Down randomly then click Enter to see does it responds.

    After screwing around with a system for 2 hours that worked yesterday but didn't work this morning, your suggestion worked!
    On mine it was the fn F2 that switched between options that didn't exist elsewhere.
    I actually went through the whole registration process just to tell you that and maybe help others.
