    How are you trying to connect it?  It's late in the day and my psychic vibes have run down.

     

    Do you have a spare cable to try instead?  Sometimes video cables just up and die.

    I have a similar problem. Yesterday, at 10.6.8, I could connect my Macbook Pro using an HDMI cable to my TV and could see everything on the MacBook screen. After installing Lion, the connection only shows a picture of a galaxy and only show the preference panes but no folders nor browser windows. Before Lion I could browse and watch streaming videos, now, with the same setup, only the galaxy.

    Can you drag windows over to the secondary display, and have them viewable there?

    I have found a new option that toggles the TV screen or, I gather, any mirrored screen:

     

    Systems Preferences->Arrangement->Mirror Displays   <- check to turn it on

     

    1) Systems Preferences->Displays->Show Displays in menu bar      <- check to turn it on

    2) Click on display icon in menu bar: "Turn On/Off Mirroring"    <- toggle

     

    With it toggled off, the only thing the TV shows is the System Preferences window (if open). When toggled on, it shows my MacBook screen and I can use the TV as a monitor.

     

    Oddities:

     

    1) It only shows a grey background on both my monitor and the TV when toggled on. When toggled off, my MacBook monitor shows its normal background, but the TV still shows the grey background

     

    2) It seems to only show the Systems Preferences window displayed on my monitor and no other windows when toggled off and the Show Displays does not have the Arrangement as an option

     

    3) After the option is toggled on, checking the "Show displays in menu bar" can be checked on or off and the mirrored screen remains unchanged and continues to work as before in each state.

     

    4) For some reasons I was originally getting a picture of a galaxy on the background of the TV and nothing else. After I shutdown and started again, the backgound is grey.

    With mirroring off, you can have a different background for each monitor

    Go to System Preferences > Desktop & Screen Saver > Desktop

    You'll see a lot of choices!

     

    The "Arrangement" is only shown on the primary display.  You don't need it multiple times.

    "With mirroring off, you can have a different background for each monitor

    I've seen all the choices and have been using them for years. I have my own folder for random backgrounds and I use the Cosmos screen save.

     

    This issue seems to be that with mirroring off, I do not have more than one monitor ("not each monitor") and I get my usual random backgounds and screen savers. With mirroring on, I only get a grey background on both my MacBook and TV. I do not see anywhere in Desktop & Screen Saver that affects this. It seems only to be a function of toggling mirroring.

    This is something I did not experiment with. 

     

    As soon as I found that Aperture in fullscreen mode under Lion overlaid both my external monitors with a grey pattern, I reverted to Snow Leopard.  There was no longer any point in Lion for me. 

     

    I should have expected that the implications of Lion's new multi-screen "support" were more severe.

    Now I am getting my background on both my MacBook and my TV and it is working normally, randomly changing backgrounds as before. How I did it, I do not know.

     

    To observe what is going on I set Preferences->Desk Top to random pictures every 5 seconds using my own background  jpg folder.

     

    I left mirroring toggled ON but I turned off the TV and disconnected the HDMI. The computer went to sleep as I had other things to do. I woke the the TV. Then  I reconnected the HDMI, then turned on the TV. I had mirroring still toggled ON and the TV came up as a mirror WITH my random background. Et voila.

     

    My best guess is

     

    1) toggle mirroring ON (this may not be necessary)

    2) connect the TV

    2) turn on the TV

     

    Mirroring ON - randomly changing backgrounds on both synchronised

    Mirroring OFF - randomly changing backgrounds on both, but NOT in sync.

     

    Also, with mirroring OFF, I can drag windows from Display to Display by dragging to the right from the MacBook to the Secondary monitor. I can then move the cursor between monitors by moving it over the right-left boundary. I can move the window back by dragging it left. Toggling mirroring ON, then OFF loses what I had on the Secondary Display.

     

    Also Preference->Display, inititially shows my TV as "Secondary Display". When I leave that panel I cannot see any other Prefenences. When I go to back to Preference->Display my TV even shows the name of the TV brand!

     

    The only mystery left is that with mirroring toggled ON, they are in sync and I get the SAME backgrounds on both. With mirroring toggled OFF, I am getting random backgrounds changing at the same time but they are DIFFERENT images on the MacBook and the TV!  I suppose this is "working as designed" as it makes each monitor look different.

     

    Curiouser and Curiouser as I don't think the MacBooks had these abilities before. Mirroring was presumed to be on and you could not toggle it. The Lion design is a lot better.
