Have used the PS 3D display for a month, swapped back with my trusty Dell U2410 and I am happy again.
Major problems
1. Glossy and reflective surface
2. Serious ghosting with games (I only have Musou games anf GT5, though, movies are not as much)
3. Black is whiter than grey
4. Dithering is very visible
Non-major problems
1. The speakers should be removed since they sound so bad but they make the TV bigger
2. Non-standard mount (not VESA)
3. Obviously limited colour space comparing to a similar priced monitor
That's a smorgusboard of bad, but the bolded is a real pet-peeve. Samsung does the same thing with their monitors (well, they don't even have non-standard). VESA mounts! Is it really that much to ask for?
