I also have an old 32 inch CRT for my pre-Gamecube/Xbox consoles, and SNES in particular still looks absolutely gorgeous on it with a smooth, vibrant picture and basically zero input latency.

27 years after its release, Donkey Kong Country in particular is still a beauty.

Did all my gaming on a 1080p 32" Samsung from about 2008-2018. Held up like a champ and is still in use today with my little brother.

Been doing all my gaming since on a 55" 4k TCL 6 series. It's been nice but is starting to lag a bit.

I'm about to become a homeowner and will finally have enough space for a home office. Will put my PC stuff there and my consoles in the living room.

So my next purchase will probably be a 27-32" HDMI 2.1 monitor around Cyber Monday this year, followed by a 65+" HDMI 2.1 tv either this year if I find one in my price range or next year if I don't. I want all the bells and whistles but don't know if I wanna spend $2k+ yet. After that the TCL will go in the bedroom.

I play on a 65 inch 4K Sony Bravia TV.

I have a LG OLED C9 since almost two years, so 4K 120 Hz HDR VRR (G-Sync compatible) ALLM (auto low latency).

My PC can use this display mode and it is awesome!

In PS5 mode it currently lacks the VRR and ALLM, I hope Sony fixes that in the next months.

My Xbox One X supports VRR and ALLM, but due to HDMI 2.0 it's limited to 4K 60 Hz HDR VRR ALLM.

The video signal of my PS4 Pro runs though the PSVR-box, so it is even more limited (no HDR).

The Switch is of course limited to an 1080p 60 Hz display output.

Half of my PC gaming time I play on the LG C9 from the sofa, the other half I'm sitting in my gaming chair and play on my HP Omen 27, so 1440p 165 Hz G-Sync.

In my bedroom I use a Gigabyte G27QC 165 Hz 1440p Free-Sync monitor for most games, but sometimes I play on my TCL 49S517 4K 60Hz television. My main PC is connected to the monitor and bedroom TV. My PS5 and Switch are connected to the bedroom TV. 

In my living room I use a 75 inch TCL 6-Series 4k 120Hz Mini-Led Qled VRR Television. My Xbox Series X is connected to this television. 

These days though most of the games I play are on my Oculus Quest 2 or Switch

I had only a hd tv for almost 14 years and I promised myself when I moved I would get myself an new expensive one.

I ended up with an 8k LG TV but I have no idea what the specs are, I only know it can do 120 FPs/4k option aswell. (Cause some tv's can play a game at 120fps or 4K but not both).

Quick tally so far:

4K (18) vs 1440p (10) vs 1080p (16)

4K is outpacing 1080p (on a gaming enthusiast site) 4K adoption is 'going well'
VRR though, just 7% so far. I imagine it being a lot less when looking at the average gamer.
Might be interesting to see how it progresses over the generation.

I'm mainly gaming on my TV, a Samsung UE49NU8000 (2018 model series)
it's a really great TV in many aspects, but I'm a little sad I didn't go with the 55" version, as that one has 120Hz (up till 1440p) and Freesynch support

Just bought two weeks ago 48 inch LG Oled C1. Now I just need to find a PS5 to see what this TV can do.
