Ultrawide Monitor VS 4K monitor

Anyone have experience using CATIA on Ultrawide monitor verses a 4K monitor?

What format is better?

Is CATIA optimized to run at 1920X1080? That is what my laptop is using with no issues.

When using higher resolution, some settings are needed to make the mouse larger.

Additionally the font and Icons can are very small.

Thanks in advance for sharing your experiences.

I ended up with this monitor.  I am not recommending LG over other brands.  My research was around resolution and screen size, not brands.  It is working out well.  I typically work as shown the below image.  Most important to me, the text is easy to read.  On the right, my Display settings.
