I just returned a vizio p quantum, and got the Hisense. I had them both hooked up for comparison, and liked the Hisense better. It seems more vibrant and clear. I would say they both looked great in game mode. With 4k, and HDR, they were fairly equal. I have Directv, and my final determining factor was the Hisense looks so much better with Directv. The Vizio had a lot of judder, where the Hisense is a lot smoother. Hisense also has a much better picture with my 1080i signal. I guess that says the Hisense upscaling is pretty good. I do see my corners are a little darker, but I don't notice it in normal viewing. I see no other bad screen effects. Watching some preseason football this weekend, and the picture was awesome. Nice and smooth.
So far I really like the T.V. Gaming in HDR on my Xbox one x is great. My colors are bright and vibrant, and everything runs smooth. I don't have any issues with a cloudy picture. I tried the Vizio on 120hz, at 1080P, and really didn't notice any difference between that and HDR at 60 hz, other than the HDR looks a hell of a lot better. So I don't see the Hisense not being able to do the 120hz 1080P thing, as being that big of a deal, at least to me. I was tempted to get the Sony 900F or the Samsung Q70, but really wanted to spend as little as possible, and still get a great picture. The H9F has really impressed me, so I'm a happy camper for now. (it's only been a few days)
I look forward to reading more on this forum for some tips, and picture settings. Good luck to all who try this set out. I think it's a winner.
