How can I check to see if my computer supports 4k?

How can I check to see if my computer supports 4k? My monitor stopped working, so going to buy a 4k monitor.

I have a 3080 graphics card which I think is fine, but my computer is an Intel Core (TM) I9 10900KF CPU @3.70 GHZ with 20 cores when I look through the device manager, 32 gigs ram, etc., but not sure where to look to see if it supports it. It's custom built around 4+ years ago.

I'm using a backup monitor from my work which doesn't have sound and is a smaller screen, so just going to order one with sounds, 4k, etc.

Also can I lower the settings to go below 4k when I want to to make it cooler in the room/less load on the computer?

You can run 4k on a potatoe these days. My laptop runs 4k beautifully you'll be fine. If you need to in some games scale down the resolution to a 16x9 compatible (1080 or 1440)

Thanks. Assuming I can do that on all 4k monitors hopefully. Games like Cities Skylines 2 are impossible on higher settings though as it gets so hot in the room, so I have my computer set to low power and FPS limited on that game.

That's still a very capable RTX card.
You should take advantage of DLSS whenever a game supports it.
It's still the best image reconstruction in the biz.
Better than a temporal upscaler like FSR, which - while good, definitely improving - can cause artifacts and noise on finer details like foliage and hair, where DLSS offers a cleaner result using the dedicated ML hardware in the RTX series.

You can use balanced DLSS settings to go from a baseline 1080p or 1440p (and other arbitrary resolutions) up to 4K. It won't be a legit 4K (typically 2160p for games), but it will look very good on a 4K display. Certainly more pixel data than just setting the game to 1080p or 1440p and outputting to a 4K panel.

Pantheon may get proper DLSS support soon. They misfired with a crude implementation recently, but better DLSS support is likely on the way.
For FSR (which is GPU brand agnostic), it still uses the older FSR2 I believe.
FSR3 and 3.1 have much better motion clarity, as well as Frame Generation.

Thanks. I just ordered a Pixio PX27u wave 27. Now I need to figure out what kind of HMDI cable to get that'd work okay with my computer.

Just remember not to use this game as any sort of indicator as to how well your card runs 4k. This is a unity game and the performance profile is completely different from your standard modern 4K game.

In other words, this one may feel like it runs poorly while much more graphically intensive modern games run quite smoothly.

An RTX 3080 should do 4k with no issues.

Must you have speakers integrated into the monitor? I would never consider anything but separate speakers plugged into a dedicated sound card / mobo sound card! Oh, well. Good luck!
