Studio 1749 HDMI Connection to TV -- No Video on TV

I have connected my Studio 1749 to my Sharp HDTV with an HDMI cable.  But when I put a movie DVD in the 1749, I get no video on my TV.  I have the Input on the TV set to that HDMI port so that is not the problem.  Any help?  Please?  Thank you.

Hi Bayoujoel,

When you plug the HDMI cable into your HDTV, does the desktop appear correctly?

Yes, the desktop appears correctly.  I should be able to see the desktop on the tv screen but I do not.  Nor can I see a DVD when I put it in.  I tried the F1 key but that does nothing.  I think that is about using a projector and not a TV.

The desktop does not appear correctly ON the TV and it should. You should mention your operating system. Make sure both the laptop and the tv are off when you connect the hdmi cable. Then turn on the tv and select the right input and then turn on the computer. With HDMI the computer screen is usually immediately seen on the tv if you have windows 7. If it doesn't appear recheck your Display settings on the computer. The F1 key is used to switch to external monitor, but you might need to use the Function key with F1 to get it to work. However, that is for a vga connection and it's not usually necessary with an hdmi connection.

You are correct.  The desktop does NOT appear on the TV.  Nothing does.  It is black.  I have tried what you suggested.  I have Windows 7 on my laprop.

The procedure is in your manual <ADMIN NOTE: Broken link has been removed from this post by Dell>. Try following that first.

Thanks.   But I had tried all of that and it did not work.  I evern called Dell support.  But the guy knew less than I did and could not come up with any option that I had not tried other than updating the video driver, which did nothing.  All he could do was suggest I call another Dell support number that offers good support for a fee.  Thanks a lot for that.

I am not familiar with the graphics settings for that system but there should be a way to determine if an external display is connected when you plug in the HDMI cable. Then once it's connected, you need to enable the external display.

You would think so.  I know that the computer recognizes the HDMI connection to the TV and the TV recognizes the HDMI connection.  But nothing is showing on the TV...just a black screen.  Very strange.

Ok, that's only the first part. Now you need to enable the external display. On my old Latitude, you can toggle displays with the Fn-F8 key combination. Did you try that?
