Yup, had one since last friday...
Picture quality is the best i've seen on an small LCD yet, you have several preset screen displays which are handy, plenty of inputs, though irritatingly no Component and you can't use very big SCARTs as they touch... as i found out
I run my DVD through S Video as a result of the above and although the picture quality isn't quite as sharp as through my top notch SCART it is still excellent.... Sky+ comes through SCART to get auto aspect switching, there is still some fuzziness on text and a slight smearing on high speed movement, but its no worse than any other LCD, in fact its a lot better than most!
Sound is ok, fine for normal TV, but i do have access to a complete Dolby Digital system so it wasn't a major concern... it is certainly ample, has a Hyper Sound system, which is plain odd - it is supposed to simulate Live, but i'm not convinced, it did work well on Top Spin tennis on my Xbox though
As for running in VGA, i connected my desktop which is a P2 350Mhz with a Voodoo 2 graphics card, so certainly not modern... i didn't even need to install the monitor, it just displayed fine - the screen is stretched to fit full screen, and it works great.
Highly recommend the unit, especially as its available for £560!
