For anything Atari 2600 to PS2 era, I play on a 20 inch CRT. For anything PS3 era to current, I play on an "affordable" 70 inch, 4K TV.

I play mostly on my PC, so my monitor is my main (as below - Samsung Odyssey G7 32")

1440P VA Panel / HDR 600 / 240hz with Freesync/G-Sync/VRR. Consoles look good on it too with built in 4K scaling. Preferably I'd want an OLED/mini LED but they're either too big for my desk (like a 48" TV lol), or insanely expensive like the Odyssey G9 Neo.

Picked this 4k monitor up back during 2015 and I'm still using it 6 years later.

The PS5 exceeded my expectations by far. The dual sense is a great piece of tech, feels great with Astro and Ratchet & Clank. I'm looking forward to playing GT7 with it. I did play GT Sport with it, but of course just the same rumble as on ps4 for now. It does feel more 'gritty' and defined (the rumble) compared to the DS4.

Ratchet and Clank looks insane, sometimes I lose track of what to look at, so much detail on screen. The HDR color is great and it loads extremely fast. I click play and have the habit of making a cup of tea while it loads, except it starts instantly now lol.

GT Sport also loads faster yet kinda pointless when you still have to wai for everyone else to load. But nice to load to start screen a bit faster. Update is still slow, must be the game. I updated both the ps4 pro and ps5 versions together (was a patch yesterday) and instead of 35 minutes to copy the game (108 GB) it took 28 minutes. (ps4 pro was at 80% when ps5 was done). Still far too long! I hope GT7 has a more sensible patch process. (ps5 game updates have been really fast so far)

My oldest has started GoT on ps5, looks good, but next to Ratchet and Clank it looks last gen of course. I haven't played it yet, want to know how dual sense works there. My kid says it's great, especially with the bow. You can really feel the tension on the string.

My wife and kids have been playing Sackboy together (I already bought 2 extra controllers). It looks good but I've gotten a bit bored of the LBP look. Doesn't look all that appetizing to me anymore. My kids added one of their friends in via share play, their friend playing on ps4. It just worked, very nice.

You can be logged into your profile both on ps4 and ps5, yet if you start the same game the other one gets suspended. (Tried starting GT Sport on my account both on ps4 and ps5, was wondering what would happen). Anyway with ps4, ps4 pro and ps5, 3 can now play on my ps+ account.

Some things aren't as good though. I prefer the ps4 UI, actually I prefer the ps3 UI over the rest. Some things now take more steps and I was using my ps4 to chat (logged into the same account) instead of the small window you get on ps5... Also I could not find how to block people on ps5. On ps4 I go to the players met list to block troublemakers in GT Sport, yet on ps5 I can't find players met, only under party, but I don't want to invite them to a party....

And one night I wanted to play R&C and it got stuck on checking save data in the cloud. No way to skip, psn had an outage in my area and thus the game wouldn't start... After I turned my router off, I could start the game and play on. I later found where to log out on ps5, another layer down in network settings. It was just a one time thing, but very annoying the game doesn't have a time out or skip option, just hanging on checking save data in the cloud.

4K blu-ray looks great, loads faster than blu-ray on ps4, has a quick resume. I turned the system off midway through, resumed from where I was the next day no problem. Maybe it's the movie, on ps4 or rather with blu-ray it depends on the series or movie whether you get to resume or load back to the menu.

Headphones work great, just plug it into the controller. The 3D audio sounds convincing in the set up, but honestly while playing I don't get as much immersion out of it as with my 5.1 surround setup. Headphones still mostly sound like it plays in your head instead of sitting in the middle of the action. The dual sense adds a lot more imo, and with headphones on you don't hear the speaker in the controller.

Anyway great system, time to play more R&C!

4K Samsung TV. Don't have a 4K console yet. TV is a year old. For my more modern systems.

2 Flat Screen CRT's for my retro consoles.

Whatever LCD came with my arcade machine,.

Haha yeah I could have put that in quotes in the poll as well. It's a shame there aren't really any standards when it comes to HDR. My laptop claims to have a HDR capable display for movie content, at 300 nit max brightness, while I can see the screen glowing where it's supposed to be black. I guess no different from HD tv. My (still awesome looking) 34" HD CRT only has 600 lines of vertical resolution. Of course there was never a 600p mode, 480p, 720p and 1080i.

I'm using an Omen 27i monitor. 2560x1440 165hz IPS. It's a massive upgrade from the monitor I used before, which was a 720p 60hz. I now use it as my secondary monitor.

im not surprised with the 1080p majority votes haha!
the tv or monitor with 1080 is fine for now,
in the foreseeable future it will be inevitable for an upgrade!

I'm actually a bit surprised 1440p is outpacing 4K so far. That after this whole native 4K push with ps4 pro and XBox One X. I agree 1440p is the sweet spot, I can't tell the difference between 1440p and native 4K from my couch on a 65" screen. Just a waste of GPU resources to push 2.25 times as many pixels for no real visible difference. (unless you sit right on top of it) 4K is good for VR.

(Not that 4K isn't nice to have, 1080p content looks great on it as well without up scaling softness you would get to 1440p)

I run a 4k, 120hz+VRR, HDR, 75" TV.
And a 1440P, 144hz+VRR, 32" computer monitor on the PC. (Not doing triple displays these days.)

No device other than the Switch has a display that is less than 1440P in my household.
