Hi there Matt, and thanks for the compliments mate.
The Vaio I use mainly for surfin', photoshop work, and when I get time I have a bash on an Edirol PCR-300 and Fruity Loops Studio XL.
I did try it connected via HDMI at 720p and 1080i, but for some reason the text wasn't as crisp as when using VGA, so I now just use that. I think the reason being, that the Sony panel's native res. is 1366x768 which is what the Vaio outputs over VGA. When using HDMI, it's ouputting at a res of 1280x720, so the screen has to upscale slightly to fit it's native res resulting in a poorer image. I have to say though, over VGA I'm well impressed !!
I've never done any PC gaming in my life, so don't know how games would run on it, and I'm still yet to watch a BD on it - laziness I know ! When I get some time, I will
see what it looks like outputting 1080p on the 60" Kuro in the front room. (though I'm still over-cautious with screen retention issues lol)
