Laptop won't recognize hdtv

Specs: Windows 7, Turion X2 TL-60/4gig ram
I hope I am posting this in the correct forum. My dad's laptop won't recognize his hdtv when he connects it to it. It is an HP DV9810us with an amd turion x2 TL-60, Nvidia Geforce 7150m graphics, 160gig hard drive and it has a vga port for external video. The haded is a Panasonic plasma tv, but it has no vga connection in the back of it. So I connected the laptop to the tv with 15 ft. vga cable on the laptop end and a vga-to-hdmi adapter on the tv end. The laptop will not recognize the tv when I turn off both the tv and laptop when they are connected. Then I tried the same with the laptop (off and on) and then the tv (same steps). I tried to connect the tv with the Nvidia video utility in Win 7 (no success). I have tried a new video driver on the laptop and tried the same steps with the same results. If you need the model number for the tv, let me know. He is running Windows 7 home premium (64-bit). The cable and adapter are both brand new. I tried both hdmi slots on the tv (same results). Help. All replies and opinions are greatly respected and appreciated.

Did you go into the TV's menu to select the appropriate external source for the incoming signal?

Thanks for the reply. Yes, I changed the setting on the TV to hdmi 1 and hdmi 2 with the same results. I had emailed Panasonic about the problem and they told me that in the manual, it states that it is not assumed that this TV will work with a computer. That said everything. The fact that it had no 'pc' port on the back of the TV should have indicated something about the TV's ability to work with a pc. So I am closing the book on this case. Thanks for the input. I know that I can always count on computing.net!

The tech is clueless, it has nothing to do with a firewall unless he meant the HDMI security handshake that is used to deter pirating.

VGA to HDMI converters are not always reliable but try lowering the resolution of your video to 800X600 or 1024X768. I've got an Integra pre-amp that has a VGA input and HDMI output and it will only work at certain resolutions on my LG TV. If I change it to a resolution it isn't happy with, the TV displays a no signal message.

Have you changed the setting on the laptop to show on external monitor?

My acer has FN & F5 to set to external screen.

A thank you would be nice, if I have helped.
