I've 32" @ 3840x2160, and it's a bless, I do coding and product design, my best tech acquisition in the last few years: https://www.benq.eu/en-eu/monitor/designer/pd3200u.html

That looks awesome. Pretty expensive from what I see after a quick search though. Does it have USB-C charging?

My previous monitor iterations have been LGs and I really like the USB-C charging capability, KVM and the OSD/buttons.

Got one of these in my cart right now: https://smile.amazon.com/dp/B07NS7JKJH

I'm gonna sleep on it and double check the return policy on this 43".

Looks nice also, but I already have a 4k 32" Eizo Flexscan that I'm happy with - I'm after the 4:3 aspect ratio, everything just seems to go wider and wider these days.
