Bout time!!!!
I'm pretty tired of watching good old SD (Standard Definition) material on the channels. We always try to watch HD (High Definition) channels if possible, but as a consequence we pass up a lot of otherwise great material that is just too fuzzy in SD to concentrate on content.
We have a 4K big screen TV and HD material looks so great on it upconverted to 4K that we don't "need" 4K material to really enjoy the images it puts out. Screen size and viewing distance has a lot to do with it. With a small enough screen or sitting back far enough from a large screen ... I guess that SD video content could be tolerable.
