From my point of view, this is the perfect office monitor, as long as the graphics card can handle the resolution. Working distance approx. 50-60 cm, ideal due to the gentle curvature and not as big as a gaming monitor. With all connections the ideal device for me (was one of the co-criteria).

For me it is about 60-70 cm

I previously had a Dell 32" 16:9 4k. (office/programming). The width was a bit too few pixels for me. The extra pixels are now perfect for 2 windows side by side. I always had to juggle a bit on the 4k 16:9. windows automatically set the font scaling to 150%, which is how I use it. Seat distance 60 - 80 cm (or further if I lean back). For me, the 40" 5k 21:9 is now perfect in size/resolution. My work notebook (hp) can handle the resolution, but only in 30 Hz. But that doesn't bother me when I'm working in the office. I had already ordered it and then looked to see if the notebook could handle the resolution. Although it said everywhere that it can only do 4k 60hz, I was then glad that the 5k at least worked in 30hz (directly in the intel graphics driver).
