CJ890 Super Ultra-Wide Curved Monitor

Yeah, I think the one that they're talking about is the same one I'm talking about. I didn't remember who made it, but looking at it now I'm pretty sure that's it, the Samsung CJ890. I remember it because I remember considering that as a potential when I was looking at upgrading my monitor years ago. The ultrawide market at the time was basically 29" and 34" ultrawide, and then that one super ultrawide. Samsung released a 49" one later and as far as I know since then the super ultrawide market has been entirely 49" and 57".

I have the 43" version of this same monitor. Properly configured it's excellent. I use it on a macOS setup with the "BetterDisplay" app licensed for "Pro".

Might depend on the model of monitor. I've a Samsung (C43J89X) that allows me to "split" the display to have it act like two monitors with no seam between. Check to see if that's supported in the monitor you are looking at. Then you have the ability to use it in different modes. Then you could stack two of these for the four monitor setup u/NoLUTsGuy mentioned. YMMV, depending on the system you have and the number of monitors supported of course.
