Recommendation wanted – Ultra wide monitor

Hello all

I wonder if anyone here has recommendations for ultra wide monitor that I can buy in Japan.

I currently use a setup of 3x 4K monitors with my Mac but interested to add an ultra wide monitor to this setup.

Do you have something that looks great and how is your experience of using ultra wide monitor on a Mac in general?

I use my Mac for surfing and watching YouTube/video’s occasionally. Some programming from time to time.

Thanks
