A:AnswerStay away from this model. It’s poor picture quality with their HDR like rather than real HDR technology. I messed with picture setting and still not happy compared to my older 40” Samsung with 60hz refresh rate. This one say 120hz refresh rate but questions you are asking, which I understand to be important, but for this TV, it’s just poor upscaling technology. I paid close to $450 on sale but will end up throwing in spare bedroom due to bad picture quality overall. Pay attention to chips that are built in for HDR to support current and newer technology when it comes down to 4K TVs. This one is junk!
