That may be one problem. Since your Panny should have VGA input and your Sony has VGA output, try that instead. At that point it will likely be a function of the video card/driver settings that permit or restrict output resolutions, and the input restrictions on the Panny via VGA.
Can you take a picture of what video output setting you have available on the Sony when you try a VGA cable? The screen grab was helpful, btw.
I have a Sony Vaio VGN-SR29XN running Vista which I an connecting to my Panasonic Viera TV using a VGA to HDMI converter like this one:
I have reached the point where I can extend my desktop to the TV screen. This is the second screen, i.e. the task bar / start button remains on my laptop screen.
The problem is that we get a black vertical bar towards the right hand side of the screen and further to the right it is repeating the left hand side of the display. Also I am not seeing the whole size of the screen, eg. a window that fills my laptop screen, when dragged to the second screen, missses out the top, bottom and sides of the window.
I've taken a photo of my TV to try to help explain the problem (can you tell I'm getting desperate for a solution now?!):
1024x768 is the only resolution I have found from the list that gives me an output on the TV (even now I am using extend desktop). I have tried all the various aspect ratios on the TV but the only ones that get rid of the black bar are "zoomed in" too far so I can't see a lot of what's on the screen.
Any suggestions please?
Thanks in advance,
