@luft262 What did you decide? Did you get anything?
Sorry, I should have posted something, but I was waiting until I got everything set up the way I wanted. I went with the 85" Samsung QN90A QLED. I couldn't bring myself to spend 5K on the 83" LG or Sony OLED. That left the LG 77" OLED or 85" QLED. After a lot of research and contemplation I decided that there is no replacement for size. My wall could fit up to a 100" TV, but the cheapest 100" TV I could find was a TCL (mid-range) panel for 10K. The QN90A is also available in 98", but it's 15K. Going above 85" is like going of a cliff in price! The 85" QN90A is $3,300 and the 98" is 15K...crazy huh! I thought about an upfiring projector, but my room has a lot of windows and we use the TV during the day or with the lights on probably 40 to 50% of the time. IMHO a projector is a better option in a dedicated theater room that can always get dark.
So even after everything I was down to a 77" OLED vs an 85" QLED and I decided that although the OLED is a slightly better panel, IMHO the advantages could not make up for the size difference. Our living room opens into the kitchen and I/we spend a decent amount of time watching TV from the kitchen as well and the larger screen is more visible from 30 to 35 feet away. (our living room seated position is 9 to 10 feet from the TV)
I've never owned an OLED TV and I don't have any friends who have one, so I can't give you a good direct comparison. When I bought our previous TV 5 + years ago I had to choose between a 55" OLED for 2K or a 60" QLED for $1,200 (that was the largest size that would fit in our TV entertainment center at the time, before we got rid of it). I went for the QLED for increased size and savings and I did the same thing this time. I've only seen OLED TVs in stores and read about them online. In my 20 years of TV buying history (I'm 36) I've owned a 28" CRT, 32" HD CRT, 47" Vizio HD LED, 55" Insignia Roku HD, 60" Samsung 4K HDR (edge lit), and I installed a 75" Vizio 4K HDR (full array) LED at my inlaws. Of all of those TVs the 85" QN90A is clearly the best, but that's to be expected as its bigger, newer, and has a full mini-LED backlighting array.
I think Samsung is in a strong position to compete against OLED with their QLED panels, because the consumer will always have to choose between a larger QLED display or saving money. The FOMO YouTube channel another user posted above really helped in my decision as well as the video below. In the video below they compare the Samsung QLED to the Sony OLED and the two are pretty similar.
I guess IMHO if you have a very large budget you're going to get either the Sony or LG 83" OLED TV, assuming your room can accomodate that large of a TV. If you have enough money and space to have a dedicated theater room then you'll probably get a projector instead of getting a 100" TV.
If I had to give a simple guide to TV buying IMHO it would be this.
Can your room fit an 85" screen or larger? If yes, and your room is not a dedicated theater room that can always get dark, get the best 85" TV you can afford. If it can always get dark and you can go larger than 85" consider a projector
If your room can't fit an 85" TV then get the largest and best TV you can afford.
My TV preference without considering price would be 1. Sony OLED, 2. LG OLED, 3. Samsung QLED
Within the limitations of budget, panel size etc. I chose the Samsung QN90A 85" and it looks great!
P.S. I drilled holes and fitted grommets to hide the wires, but I didn't have the wire snake tool yet at the time and couldn't get the wires past the insulation. I now have the snake tool and when I get a free day I'm going to hide the wires behind the wall. I'll send an updated picture at that time.
Thank you for your help/information and I hope this post might help someone else in their TV buying decision making process.
