Lack of Monitors Over 1920 x 1080?

I search online (primarily Amazon) and find that most monitors around the 24" - 27" range are 1920 x 1080.

My current monitor is about 6/7 years old, only supports up to 1680 x 1050, 20". If I bought any old 1920 monitor, the likes of LG, Acer or Samsung (or whatever), would I really see a huge difference? I sort of feel I wouldn't notice much difference if I bought a 23"

Currently trying to decide if I should just buy a new monitor, or save a little while longer and splash out on a whole new system. Or get the monitor now that I could use on the new system anyway.

Thought about dual monitors but the majority of the time, the second monitor wouldn't be used so am not particularly looking at that anymore.

I did like the look of ultra wide-screen but I don't know if it's really worth it. Same with curves. I sit around 65cm from the screen. I sort of think an ultra-wide screen would have me moving my head to see everything.

The LG 23MP68VQ monitor I was looking at has come down by £10/£15 just today. But it is only 23".

I don't do much gaming (Planet Coaster is the most recent), but when playing, I can hear the fans racing hard, which is what made me think of a new system all together. But then I don't know how much gaming I'll really do in the future a I'm about to start a family so won't have much time. My PC usage has dropped by about 20% - 30% in the last 2/3 years. I'm a bit of a snob for wanting the best (I can afford) though.

So is it really worth jumping to 1440, or should I buy a 1920 monitor now, then it'll be good until most monitors are 4K, so buy one of those if I need it in years to come?

Any advice?

Yeah, a lot of the monitors in the 24"-27" range have gone for size over resolution to keep prices low. For my sons build, I did a 1920x1200 Dell Ultrasharp IPS for his primary monintor and we added a second 23" IPS panel at 1920x1080 monitor which we got for a low price.

At work, I used a 27" Dell Ultrasharp IPS which offered 2560x1440. That was really a solid sweet point for me. I prefer the extra resolution and will gladly spend extra on my monitor since that is the thing I look at every single day. I always cringe when I see an awesome system and they buy the cheapest budget monitor they can find. Also, for me, I know that I cannot really see the difference between 60Hz and 144Hz, and being in my 40's means that I also don't have the reflexes that I once had, so I don't have to pay more for monitors that offer more than 60Hz...that's all just lost on me.

Not sure what you're seeing, but I just went to NewEgg, did a search for 24" to 27" monitors, in 1440 and 4k and came up with 5 pages of results, ranging in price from $160 to $2k.

From the sounds of it, before investing in a monitor that's going to tax your system even harder, an upgrade to your current system is probably in order. 4k is hard to drive in gaming still, at least at decent enough settings it's actually WORTH running 4k.....there's no single card solutions right now that can pull it off well enough for me to do it.
