    Excellent display

    I have been using this screen for several months now, mainly for office work (Excel, Power BI, Database...). A 34 inch ultrawide QHD screen is much more comfortable to use (number of Excel columns, number of visible tables...) than two 17 inch screens. The articulated stand is a nice addition.
    As usual, the delivery was on time, no defective pixels.
    I use it in a dual Windows/Mac environment with no worries
    To sum up, I'm happy with my choice
