Is anyone watching video of any kind on a 4k monitor or television? What are your impressions? I'm curious, the 4k Ultra HD TV prices are coming down but I am unaware of any 4k content being produced. I am wondering if these TV's and other devices can up-convert from 1080p to 4k or close to it. You would think they would have to get early adoption of 4k off the ground. I also recall hearing a while back that Sony is working on a 4k DVD disc system but haven't heard any more about it.
