    Product chosen on the advice of the LDLC team, which perfectly meets my expectations.

    The USB-C connection is perfect for connecting it to a MacBook: a single connection for all peripherals. No cables dangling around.

    Great office/graphics monitor

    My criteria when buying it were:
    -4k
    -27"
    -at least 95% DCI-P3
    -VESA-compatible
    -USB-C PD 65W minimum

    I’m very pleased with it; everything is great. You get used to the resolution very quickly, and it’s hard to go back.

    The only downside, if I had to find one: you can’t set the video input to automatic, so I have to manually switch the source between a work PC and a personal one when working from home. I’m also worried that the multifunction button used to navigate the menus might eventually give out (that happened to me with a samsung monitor).
