Yes, the costs rise quite sharply as you move away from the "old" 24" 1080p monitors. Now we have 1440P, 4K and even 8K with refresh rates up to 360Hz, and G-Sync or FreeSync adaptive sync options. There is true HDR and then also curved panels with different aspect ratios.
The article below is by no means exhaustive, but it gives some good pointers. Don't forget though about whether you want speakers on a monitor, a headphones/mic plug, the type of connectors, and of course ensuring it matches your computer's GPU card. And of course the issue of a multiple monitor setup vs an ultrawide screen. I still prefer my three monitors as I can play full-screen on one whilst having game maps and other info open on the other screens.
