Replacement display, calibration question (plus geeky stuff)

My current display is around 8 years old and probably close to end of life. While I can do a basic calibration without a tool, who knows where its colour balance sits after all this time.

Started looking at displays: rabbit hole ...

After much reading it appears that, unless I want to spend a lot of $ I'm going to end up with a display that covers 100% of sRGB, but not a lot more.

As far as I can tell, my options are:

1. buy an inexpensive display that has a reputation for "pretty good" out of box calibration and call it a day.
2. Buy the above + calibration tool and be happy with consistently pretty good over time.
3. Buy something like the Asus proart and know that I have good colour out of the box and worry about calibration later.
4. Buy something a lot more expensive that covers some portion of dci-p3 because ... ?
5. Spend a bit more than a Proart on a Samsung QLED HD TV and get 100% (or maybe a bit less) of rec-2020 but who knows about calibration

: WARNING, geek heavy!

The rabbit hole:  With any new tech comes a flurry of hype bs and false promises and so it is with HDR.

Rec2020, HDR, DCI-P3 and more oh my...

HDR is not the same as a wide gaumet spec like DCI-P3, but, as I understand it,  can encompass the wide colour space of dci-p3 plus other stuff like minimum brightness and black level.

HDR ready = pure bs.  "We like the word and our marketing department insisted, but it's not hdr.  We're just faking it."

HDR400 certified.  Still not really hdr, but at least its 100% sRGB and rec207 plus higher brightness and good black levels.

Beyond those certification levels you actually get something in the way of extended colour space.

Intriguingly, Samsung claims 100% dci-p3 (but does not tell us with which models or under what conditions).  Marketing ...

Fortunately these guys did some measurements and Samsung's claims, while exaggerated, are credible.

Other geeky stuff: components matter  Most displays use the lowest cost components that meet the engineering spec.  They probably vary over time.

The good news in this is that lcd/led monitors last a long time, even the cheap ones.  I have some 10 year old 19" $100 Acer monitors at work that are still running.  Around 15 of 45 ish originally bought for our office.

But ... the cheaper monitors probably drift out of colour spec more quickly than some of the more expensive [s] graphics [/s] creator displays.

: END GEEKY STUFF

Back to my use case. I'm not printing anything and at work where my pics are on a background slideshow I am displaying at 1080 on non-calibrated monitors.

Given the above, I don't need rec2020 (which nobody can provide from what I can tell) or even dci-p3.  The latter is probably a would-be-nice thing.

While a 35" Samsung that is close to 100% dci-p3 is intriguing and maybe a good budget option for those who do some printing, option #2 for close to the price of the Proart seems like a very good long term option.

Question.  Can even inexpensive displays be calibrated properly these days?  Back when I looked into calibration for projectors that was not the case.  As I remember it, there is a need to do gamma correction for a proper calibration and that was not accessible in cheap displays or TVs.

If I can do a proper calibration, option #2 seems the best choice.

If you made it this far, thanks for reading.
