I am trying to hook up my hp laptop to my sony bravia tv and when i make the connection the laptop monitor goes black and the tv says unsupported signal. I then have to reboot the laptop to get the screen to turn back on any ideas?

To you use it as a monitor , hook it up to HDMI or USB port , go into settings and activate from there.

Try booting the laptop with the tv connected. or try changing the resolution of the tv via the ati software.

try setting the frequency down to 60hz and the resolution before you connect. then if it works you can set it up again with a setting the TV likes

You need to:

- Connect everything with the laptop turned off
- Boot the laptop
- Use the Fn key plus F8 or F9 (I'm trying from a small picture of the keyboard!) to cycle through the external display options.

you did not mention the model of your tv. usually lcd tv's only support some resolutions.

right click on your desktop choose properties then settings you can change you screen resolution there windows will change back in 15 seconds to the old resolution. try the different resolutions availbe to you.

Try going into system preferences, then into displays, and see if you can select another monitor to show up by selecting detect displays.

It sounds like your LCD Screen is no longer working. I would try contacting Sony and ask for a refund. I had the same T.V and the LCD Screen had gone out. A techniction came out and Condemned the screen and i had to pay $500 for a new T.V.

'Unsupported Signal' Error indicates that TV is accepting the signals for Video but not able to display because resolution doesn't matches. Else the message would be 'No Signal'.
Follow the steps-
NOTE- Make sure cable is 15 pin(at both ends) VGA cable, working fine between PC & Monitor.
1.The standard resolution of laptop(any) which would support is 1024*768.
2. Toggle the display output from Laptop Fn Keys depending on Laptop Brand.
3. Connect the cable after settings made.
Also PC Settings will not be highlighted until connection is made.

u have to set screen resolution of monitor to 1024 *768

"Unsupported signal" suggests one of two things. Either the refresh rate on your computer is set too high (it MUST be at 60 Hz.) or you have the display resolution set too high
