Your 4K UHD Blu-ray player has an expiration date

Your DVD player has an expiration date. Your Blu-ray player has an expiration date. Yes, your 4K UHD Blu-ray player also has an expiration date. In the case of DVD and Blu-ray, those players had their expiration dates for me because I wanted to get more picture and audio quality out of my discs, and that meant I had to move on to a newer player. That doesn't mean those players stopped working, but it meant I unplugged them for good when I picked up a 4K Blu-ray player.
