I received my L220x about 10 days ago - about 10 days after ordering. I'm still in the first throes of infatuation. (I was using a IBM G94 19in CRT before, about 10 years old). The dealer suggested that the L220x was an end-of-life product, but so what there's always something newer and better just around the corner.
My main concern is that the monitor outclasses the rest of my system so now I have to consider upgrading everything else. I wasn't sure if the Nvidia Geforce MX420 would be able to drive it OK but all is fine. I only have VGA but from what I've read here I might not see much difference with DVI. Also I realise I need to improve my limited knowledge of profiling and calibration. It would be good to hear some feedback from the people with calibration devices on order with their experience of using them with this monitor. In common with others I note that red and green are over saturated (monitor set to sRGB as per Erik's suggestion).
A couple of minor things:
Not sure what the blue clip at the back is for apart from locking the monitor at minimum height setting in shipping?
I didn't spot at first that you have to install the soft OSD to use the rotation feature. I was quite surprised because this just worked right away once soft OSD was running. I thought the old low-spec graphics card would probably not handle it. Not that I expect to use this a lot but it could be nice for viewing portrait shape photos.
This thread has been a mine of info. Thanks Erik and others.
