Pros and cons

According to our monitor expert

Enjoy sharp images thanks to the Quad HD resolution.
See more of the playing field or use multiple windows at the same time on the wide ultrawide screen.
With a 180Hz refresh rate, you can play fast-paced games smoothly.
An ultrawide monitor takes up a lot of space, so your desk needs to be large enough.
To get the maximum refresh rate of 180 hertz, you can connect the monitor with DisplayPort.

Iiyama what else ...

Nice wide image
Easy installation
Sufficient adjustment options for tall people
Fragile joystick to navigate through the menu

After a week of use and testing, no dead pixels found yet... otherwise a very nice image... played DCS flight simulator in high resolution, sublime... good to know that the highest resolution is only achieved with DisplayPort
