I think firmware update is quite necessary for 3d effects. Hardware are important too but software can make your video more clear and better.niceguy1234 wrote:I don't think it is matter for 55" 60" because I first purchased the UN-55D6500. 3D movies is very good before and after the firmware update I I forgot the firmware version). That panel was pretty good too without flashlight and clouding. I returned it because it was not big enough for 3D movie, and picked up the UN-60D6500. The 3D movie is also good before and after the firmware update. I think the firmware update does nothing to do with 3D effect. I am thinking the hardware inside the TV might be different between the European model and the North American model. So far I did not see any complaint from North American users. I will try to provide more information for my TV after work.
I only thing I don't like the 60" is the response time is not as quick as the 55" one. If I pay extra attention to the image, I can see trail especially for the HD cartoon programs.
