PC input to Sony Bravia - from Sony Vaio Laptop - unsupported sig

May I know whether you are using onboard graphics card or an installed graphics card like nVIDIA or ATI? If you are using the latter then yuo can directly connect using the DVI port. The ouput signal from your DVI port will be HD by default and no adjustments are required. Just plug and play!

"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

Hi Julie,
There are a couple ways to go here. I'll give you the procedures step by step. If you want clarification on anything, just ask. If I make an assumption that is wrong, stop me and let me know. The more you know, the easier this will be for both of us.

First I'd like to double check on MisterSony's diagnosis. Refresh rates that are too high end up as a black screen on many LCD models.

This is my first assumption, the display settings are currently for both monitors. Your original screen is still functioning.

If so,

• Right click on your desktop
• Click Properties
• Click the Settings Tab
• Click the Advanced button
• Click the Adapter Tab
• On the lower part of that tab, there should be Refresh Rate. If it is not at 60 Hz, try to change it to 60 Hz.
• Click OK
• Click Apply
• A pop up may appear asking if you want to keep the changes. Accept the changes.
