A:Answer The only movie I've watched on it so far is Planet Earth II in 4K UHD Blue Ray. 4K UHD with HDR should make the Blacks darker and the colors brighter. If it's too dark, go to the settings and turn off the HDR feature in the DVD player. I had it off for one DVD and it still looked good, but when I turned it to Auto, it became a bit darker. Also, check the TV picture setting, if it's a Samsung, switch from Standard, Movie, and Dynamic to see if it makes difference. Also, are you using an HD HDMI cable? One that transmits at least 18GB per second of bandwidth? That will also help. I'm not an expert, but I was able to find the best settings for mine. Hope this helps out.
