I'm interested in finding a crosstalk free 27 inch TV/Monitor. I heard good things about the LM series from LG, but I wanted a TV in smaller size and without the built in processor/internet TV related components.
Acer has a 27 inch passive monitor (HR274H) and so does Viewsonic but I'm not sure it is available yet.
23 inch passives are made by LG, AOC, Acer, Viewsonic, Asus & HP. Not sure how many are being sold vs in planning.
My passives all show crosstalk on light objects in a dark background. Though seldom noticed in normal viewing it becomes noticeable at times.
Have not tried it with good video material - I am yet to build the htpc for it - so cannot really comment on that. I did not notice any cross talk with the low-res, skip-frame yuotube 3d videos I tried with an old htpc.
