I have a Dell Studio 1737 laptop with an HDMI port. I'm trying to connect it to a 42" Vizio HDTV (brand new). It's worked once, but that's it. Not again. I connect the HDMI cable to the TV and it just says "No Signal!"
After selecting video input connection type (hdmi) on hd tv, try right clicking on desktop and go to graphics options. Select desktop plus hd tv or just hd tv. This works with Dell Studio 1555 and Sony Bravia hd tv using the hdmi inputs.

FYI I subscribe to Netflix streaming video and use my laptop and internet connection to watch movies on my big Sony HDTV as well as the internet using a wireless mouse and keyboard. The laptop (Dell) has HDMI ouyput and Windows 7 with the magnifier function which allows me to see the HDTV from at least 17 ft. I connect with a short HDMI cable and leave the laptop near the HDTV. I guess I could run a long HDMI cable and put the labtop near me. I presume others use other methods and devices such as described at the Netflix site. See above with helpful.
This didn't fix my problem and it gave me an additional problem. I did this:
right click desktop > Graphics Options > Output To > HDTV.
Result was: My laptop screen went completely black, but TV still says, "No signal".
Now the only way to see anything on my laptop is if I disconnect the HDMI cable.
To make matters worse, NOW when I right click my desktop again and select Graphics Options, there is no more "Output To" option on the menu, so I don't see a way to un-do what I just did.
I had this same problem. Took me a while but I figured it out. Right click on desktop and select "Personalize". Next click on "Display". You should see "connect to a projector" on the left. Select it then select duplicate. Its that simple.
