If you have a 4K-capable display or TV sitting in your house or office somewhere and wanted to play some content on it, you might want to check out Sony's Video Unlimited 4K service.
Sony's Video Unlimited 4K service offers up 4K content to rent or buy on Sony's 4K Ultra HD Media Player, with over 70 movies and TV shows. It includes one of my favorite TV shows of all time in 4K: Breaking Bad. 24-hour rentals will set you back $3.99, while 4K movie rentals will cost $7.99. If you want to purchase a 4K movie outright, it's going to cost you $29.99.
Sony is hoping to have over 100 titles by the end of the year, and we should see it grow extensively going into 2014.
