Computer Dell laptop doesn't detect the TV via HDMI connection.

I have a Dell Inspiron N5110 with Windows 7 and a Samsung TV. Whenever I plug my HDMI cable, the only thing I see on my TV screen is No Signal. It is on the correct entry, but my computer still does not recognize the second monitor.
I have connected my laptop to a front projector, and it worked fine.

I had problems connecting my laptop before and then finished by needing a new hard drive... So I now have a new hard drive (cool!) but I can not determine what the problem... In devices, Graphics Manager, it says Intel(r) HD Graphics Family and Standard VGA Graphics Adapter. The other has a small yellow triangle with an exclamation point, but when I ask Windows to see if it's updated, it says that Windows has determined that it is up-to-date.

Help, please!

I had the same problem as you. Initially, I went to dell drivers

video and downloaded the driver Intel HD Graphics 3000, but that wasn't enough. Yet once my HDMI has not been recognized. I had to also download the same file, the nVIDIA GeForce GT 525 M Graphics Driver (it was my graphics card, if you have the ATI card you download driver ATI). When I installed the last, I was ready to go... Download and install these two drivers and you will solve this problem!
