I listed more cons than cons, but I would definitely buy it again! The benefits are clear. Great piece of HW.
Thanks to the DDPM software you hardly have to touch the menu.
DPI for Mac is not working properly. In order to be according to Apple, everything must be big enough (2560x1080) or completely dark (5K).
KVM is great (I switch in DDPM), but it's pretty slow. My idea of clicking the mouse/keyboard from one panel to another has taken over. It is easier to have either 2 mice or peripherals that can switch inputs. Otherwise, one would have learned.

I hesitated for a long time and I do not regret it, I recommend it. Of course it's not as sharp as 5K in 27" but at a distance of 50cm from the monitor I can see everything perfectly. Huge surface area, even 3 windows can be used side by side. I switched from 2x 2K 25" monitors. BITCH!: -)

I guess I got lucky. I tested the monitor right away. No visible banding, no flickering no dead pixels at any lower brightness setting from 0-15% or anything higher. I'm mega happy with it! Expensive, but I need it 80% for work and 20% for games here and there. AND BEWARE! The monitor is capable of 10bit colour depth via DP, not 8bit as stated on the manufacturer's website. I'll attach a quick photo. Setup is not ready yet, so I don't have cables hidden - hopefully the reader will forgive me: )
Perfect picture
Perfect resolution

10bit colors! not 8bit
when the display in Widows is set to 100% - 5120x2160 px, the text is really small. This resolution would be more suited to a 43" diagonal or more. When the scale is set to 125% everything is ok.
more expensive, but if you want more than 60Hz, there is nothing else yet

A week ago I bought the nonitor for 40k, now you have a price of 65k and a reduced price of 71k. How is it possible, when you write the lowest price in the last 30 days?
the best decision I could have made

Because of the flickering I had to return the monitor, it distracted me at work and browsing the web in the evening. I might buy again if I get a better piece. The monitor has no competition yet at 2160p@120Hz UHD.
super monitor
he fulfilled everything I wanted from him
brightness above 20% is absolutely no problem
unfortunately at 0-15% brightness setting the monitor flickers (left side on white), which is quite useless in this price range
