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.

If you are getting life from your HDMI cable, meaning your tv acknowledges activity from your laptop by long-pausing before saying no signal, going dim, or simply giving you a black screen (all dependent on the tv) then it's likely a Windows update pushed your graphic drivers out of date.
To try updating your drivers:
If Windows finds an updated driver, your TV should immediately detect your computer after Windows instals it, however you'll still want to follow the recommended computer restart as you should any time you update your hardware drivers or software.
There isn't much other than messing with custom screen resolutions or breaking the HDMI cords or ports themselves that should keep your Dell model from connecting via plug-n-play. If you've followed the manual, updated your driver, tested another HDMI cord or change your resolutions back to default suggested displays, and you're still not getting proper signal, I would consider upgrading your graphic card as it may be faulty. Hope this helps.

If your TV is truly connected to your 1749 (if used for the first time, you should see your desktop mirrored on the TV. Sometimes, you may have right-click on your desktop and choose "Screen Resolution" and then "Detect"
If that finds the TV, you can mess with the options from this control panel, Including choosing "Extend these displays" from the Multiple displays: drop down menu. This will also allow you to set your 1749 and your Sharp TV to separate screen resolutions that are most optimal for you preference. This also allows you to drag your DVD window over left, right or up to your TV display.
