Re: Poor picture quality (esp dark areas) on Roku Express HD
I have a similar problem. When viewing an HD video directly from a source's website using the TV's built in browser compared to it's Roku channel the web based video has better definition and color. The internet video is 1080p, just like the Roku stream should be. This is on a web enabled 4K TV, and both the TV and Roku (of course) are connecting over wifi, just a few feet below my router. The difference isn't like that between SD and HD, or a standard DVD and HD, it's more subtle but definitely there and it detracts from the viewing experience.
