Well after two L887 units later:
- first one had a color non-uniformity issue in one corner. It went back immediately.
- pretty ok tracking, but the colour space is somewhat limited
- not the best contrast, although quite good
- even with the bigger LUT, the grey scales show slight banding
- not good for video / moving images / games
All in all not bad, but I'm tempted to say that the DELL FPW2405 I evaluated at the same time is a better deal overall, even for image editing.
