Xiaomi Mi Curved Gaming Monitor 34 review

pcgamer.com:

Curves, eh? Curves, curves, curves. Not only is an opening like that going to bring in traffic from the seedier corners of Google search results, but it sums up the way your brain works when you're faced with a curved monitor. Unless you've been using one for some time, it's hard to sit in front of a curved monitor, even one as gentle as this one, the Xiaomi G34WQi, and see anything but the curve. CRT monitors used to bulge toward us, but now this one is there in your peripheral vision, the wider-than-wide aspect ratio offering you a slice into games that's more immersive than ever.

The Xiaomi G34WQi isn't the largest ultrawidescreen out there, and it doesn't have the most aggressive curve, though it is an impressively affordable one. The smartphone maker first touted its monitors back in 2019, and it's taken a while to start selling them outside of China.  It offers a gentle 1500R—that's R for radius, and the 1500 bit describes a circle which measures 1500mm to the middle; the monitor thus describes an arc along the circumference of that circle. Remember the bits of geometry at school you slept through, thinking you'd never need? Well this is it, here in the real world. And there's no point always having a calculator in your pocket if you can't remember the formulae.

Naturally, no one at PC Gamer can remember the formulae either, but it doesn't matter. What you need to know is the higher the number, the more gentle the curve, because you're arcing along the outside of a larger circle. So 2000R would be less curved, closer to flat, while 1000R would wrap further around the sides due to the imaginary circle being smaller. 

The aspect ratio of this 34-inch Xiaomi screen is 21:9, making it perfect for watching movies such as Avatar 2 which were shot with such a slim, wide view in mind. Monitors like the Samsung Odyssey OLED G9 offer a 32:9 aspect ratio, exactly like having two 16:9 screens side by side but without the gap down the middle or the hours of fiddling about
