that works on 1080p for h264/vc1, also work for 4K?
Not an expert, but 4k has 4 times as many pixels as 1080p. That means
the graphics hardware has to do 4 times the work to decode those
pixels. Sometimes, it will be able to, but I think that sometimes it
won't. So, I think your conclusion is not always true.
