I never really liked multiple monitors, but they are necessary for video editing - in addition to the usual monitor, I have a Sony production monitor with accurate color for previewing the video.
Aside from that, I'm really happy with the screen I got last summer, a BenQ PD3200Q 32" 1440x2560 screen ($400 at B&H Photo, IIRC). I just want one big "canvas" for my maps, with room to have other windows as needed. I was tempted to go full 4k, but I prefer to run screens at their native resolution, and for text to be a reasonable size at 4k, I would need at least a 45" screen. Worried that I'd end up with a sore neck looking around a screen that big at close range.
One day, I might actually give it a try though.
Those ultrawide screens are cool, but a curved screen sounds a little too weird for my needs. I'm sure they are great for games, but that doesn't interest me. Also Bob, the computer specs you posted here awhile ago showed you have the Intel UHD630 graphics chip - same as my Mac. These chips don't get any love from computer geeks, LOL. They can have trouble with very high resolution screens. I'm a moderator at MacRumors.com and this is a constant source of complaints.
I know that Windows implementations may be different, but before you fall in love with an ultra-wide monitor, do some research of what other users of PC's with the UHD630 chip have to say. The common complaints on the Mac side involve not supporting the resolution or refresh rate they want, overall user-interface "lag", etc. The method of connecting to your PC can also affect this, such as displayport, hdmi or usb-c.
One issue is that, if the graphics chip works too hard, it gets hot. Since it's an integrated chip, that means your processors will slow down to avoid overheating. I think this is the cause of the "lag" that people complain of.
