The main difference between the Samsung H6350 and H6400is that the model H6350 doesn't include 3D technology. In addition, this model does not include other extras like Smart Touch control.
Our advice is that you should choose the H6350 model if you are not interested in 3D technology, because you can save a lot of money buying the lower model, and maintain the image quality.
