A very good screen
A very good screen, but this does not necessarily come from the screen because I knew it, but I find the colours of the slab rather bland. After some small adjustments, calibrations... it's better but it's not as good as an IPS screen.
I bought 3 screens to make a triple screen and it's perfect. Some softwares like iMenu are very useful to make adjustments without touching the screen.
However, there is only one button to do everything, the button to turn off the screen is the same as the menu button. To turn off the screen you have to keep it pressed, and for the menu just one click is enough to open it. I say this because I was looking for 15 minutes to open the menu on the screen. It works perfectly for me.
