The refresh rate is set at 60hz which works fine in 1024x768. I don't think running anything higher than that on an LCD wouldn't work so I'm pretty sure that's not the issue but thanks for the help
Change the refresh rate anyway - I had a recent issue where I had to change the refresh rate on Sony laptops to 59 hz and then back to 60 before they would work with the Bravias. Odd, but give it a go.
