unable to connect laptop to HDTV

[ajithxyz]

I have a Compaq 620 laptop and Philips HDTV 42HFL4482F.The OS is Windows 7 Home Basic.The cable Im using is VGA. The laptop screen goes blank and the TV screen reads Video format not supported or no video signal. The Intel graphics media driver  version is 8.15.10.2057 and the accelerator in use is Mobile Intel 4 series Express Chipset family. Also the Intel Graphics and Media control panel says Monitor/TV settings not supported. The key fn +F4 option is of no joy. Can anyone help me please.

Hi,

It seems to me NOT supported from BOTH ends (TV and laptop). Have you try to use HDMI ? Both laptop and TV have HDMI connectors.

Regards.

Greetings, 

After checking the manual of your TV there are a few things I would like to recommend. The first is to ensure that your source is on the VGA setting. You can change this by using the Source button. As well, ensure that you are plugged into the VGA in, and not the RS232 (Service Port).

If these were both OK, I would reboot your PC after connection and see if you can see a boot screen on your TV. If you can, then more than likely your resolution is set too high. It is important to maintain a resolution of 1920 x 1080 or less. (1920 x 1080 is 1080P/1080i High Definition resolution). Anything larger than this, then your TV will not display your picture, or will display it distorted.

We need to gather more information about your computer to assist you properly. If you could select the Start menu, then type dxdiag in the search box and press enter. After that has completely loaded, select the Save All button. Save that file to your desktop. Afterwards, on your desktop should be a dxdiag.txt. Open that file and copy from the top to the bottom of the Video section and paste it into this thread.

Greetings again,

Banhein is correct. You would be much better using the HDMI ports avaliable on both units. The picture will not only be much better and carry both audio and video. In most cases it is much easier as well.

If you wish to continue using the VGA cable. 

You should download the latest drivers from the Intel.com site and install them.

Your device drivers are located at:

After you have completed the install, reboot your PC and see if the issue persists. 

If these steps do not work, please post and I can continue further with the troubleshooting.
