Purchased UT50 Have a Question

Some people will tell you that only Panasonic active shutter glasses will work on this TV. I am a new owner of this TV as well and I tried the Samsung active shutter RF version and they work just fine with the UT 50. the build quality of the Samsung 3-D glasses is not quite up to par with Panasonic's version but from my own testing they operate the same. The price difference is significant Samsungs are $20 compared to Panasonic's over $60. to answer your question it does appear that any active shutter 3-D glasses that use RF technology will work.
Any 3-D Blu-ray player should be just fine the problem you could have is if your AVR is not 3-D capable that is to say if you want to run everything through a receiver like I do.
the model of glasses I'm using presently are the ssg-4100gb http://www.amazon.com/Samsung-SSG-4100GB-Active-Glasses-Models/dp/B007K9P7H0

hope this helps you:D

I recently purchased a 50ut50 and after some reading on the topic a couple pairs of the 4100gb also. For the life of me i cannot get either pair of these glasses to pair with the display and i am really irked since I've read of others having success with little hassle. So if you can share and/or link me to what magical procedure i have to follow or the root cause it will me much appreciated.
