During my brief 1905 ownership, I felt it was a bit washed out colorwise. Those whole screen had a yellowish/pale tint to it. Probably this can be solved with some tinkering in the driver software, but my subsequent 2005, and my other monitor, the dell e173p both looked pretty good out of the box, so it was a bit annoying.
And if you check 1905 threads, many many people (including me) complain about ghosting, unsuprising since it has a 20-25 ms PVA panel. So it's only good for 2d work.
