For my living room (recent purchase) I went with a Samsung QN90C - the 75" model. Got really solid reviews overall from rtings.com and I've been very pleased overall with it. Currently its 1799 at Best Buy.
I imagine there are better TVs out there, but hard to beat the quality overall in this model for the price. Especially being a 75". Handles my bright room well, and I like QSymphony aspect when paired with a Samsung Soundbar.
Another model I was looking at was the Hisense U7K, but just couldn't pull the trigger on it. If you are wanting an OLED that handles a bright room, another option would be the LG C3 77" model. I almost went with that one, but didn't want a 3rd OLED in the house.
I also looked at the Samsung Frame TV, but I decided against it just after reading many reviews and seeing content on it. To me it looks great, and I liked the idea of it, but reviews were saying that brightness was somewhat a concern and it also had blooming/bleeding issues over time.
Hope this helps a bit.
