    Great addition to my home office setup. I love the ultra-wide form factor for productivity and gaming —FPS games feels more immersive, and window management is a breeze.

    Having a Pro-motion display Macbook, the refresh rate boost was a must, and surprisingly 100Hz don’t feel that much different from Pro-motion’s 120.

    The biggest hit comes from the DPI. In specific dark websites or screens, scrolling will make it feel like the text flashes, due to the small amount of pixels and the high refresh rate. Text definitely feels not as sharp as on my Macbook, in fact it looks rather jarring. It does make the price justice.

    Colour accuracy is excellent, I can fully trust my designs don’t look bad when comparing with my Macbook screen, or the iPhone. After calibration I can’t really tell the difference, even!

    The biggest pro in my view is the sheer amount of ports: the USB-C will also charge your compatible computer, basically doubling as a spare charger for me, which is a blessing!

    Speakers of course are really bad: everything sounds higher pitched.

    Overall great investment, the screen looks slick, my productivity is up, and I’m happy with it 🙂

    It’s is such a beauty to turn on, and Samsung have fixed the input select bug from previous models. The thunderbolt support is great, and can confirm a 2022 MBP can do display+charge via the USB-C from the monitor, and the 2nd USB-C does present as a USB device too.

    I’m quite happy with this, there really is nothing like sitting in front of an ultrawide curved monitor. It’s significantly better than using 2 displays.

    Golden Review Award: 2 From Our UsersUsing this as a dual display with an iMac with Thunderbolt, a laptop with hdmi, the connections are fantastic. The side by side screen works well for what can look like two full size monitors. The controls are easy to navigate and no manual needed! I love doing my work with my laptop and having the extended display for office applications. If you work with video or music software, the extra space is brilliant. In my opinion, this rig is well worth the money.

    Golden Review Award: 38 From Our UsersSome things to note:

    + Slim and low profile – “feels” smaller than it is on a desk
    + Comfortable to use for a long working day
    + Great sounding speakers
    + Decent stand height and angle adjustment (although super stiff at first!)
    + Cable management is useful

    – Bad light bleed
    – No Thunderbolt control of screen brightness or speaker volume
    – Build quality could be better for the price
    – When waking out of power-save mode the screen turns on, then off and back on agai
