Whatever you can afford is always going to be the best answer, but since you don't list your budget at all (which is probably the most important part of it.), I'll just ask, what's important to you in a monitor?

Color accuracy? Refresh Rates? 2K/4K? Brightness? Size (giggity)? Type of panel?

I'm personally using two monitors. LG 34WN80C-B (34-inch Ultrawide), and LG 32QN600-B (32-inch). The ultrawide is my main monitor, quite color accurate and love the screen real estate, especially with Daz. The second monitor is a mix of folders, reference images, and often other lesser used panes that I just leave up there to have more space on the screen.

See link below. I love this monitor. The usb type c powers and links my thinkpad in one connection. I also linked the arm below. It’s very versatile and easily moved up, down, forward, and backward.
