I have a Samsung series 6 UHD in my office. It's not great by any means, but for a football game or something of the like its adequate, and gets a decent picture. Anything filmed in the dark, for instance the season finale of game of thrones, absolutely terrible. Anything with black filmed at night, you might as well have your eyes closed. I've tried everything with settings to resolve it, not happening. Is there any adjustment I'm missing, or is this consistent with this model. If it can be resolved, any recommendations for replacement? I'd prefer to stick with Samsung, as being paralyzed, my environmental control that enables me to control things in my house via voice is set up for Samsung. Thanks in advance for any help.
