    Hey there, and WELCOME :)

    This has worked before for me and other folks when connecting a second display or TV. Sometimes Windows 7 likes to change projector settings on you. Try tapping Windows key + P until your TV display comes on. That should do the trick.

    Keep us posted, let us know if that works.

    Best, Heather

    I understand. :)
    Did you pressing Windows key + P after you got the "Format is invalid" screen?

    Edit: Wait, which screen turns blue? The TV, or the monitor?

    All right. Something's not right.

    Do you have another monitor or TV you can connect the cable to? It's been my experience that bad cables are more common than you would think, unfortunately.

    Also, do you have a different HDMI cable, or can you try a different one?

    Windows 7 should automatically see the TV and adjust resolution for optimized output.

    (just got your images, thanks!)

    Also, do you have another device that uses miniHDMI? Probably not, but you could also try testing the cable by connecting it to two other devices, or between another device and the TV.
