UPerfect GR19BU Monitor Review: A Versatile Option for Gamers and Creatives
Key takeaways
- UPerfect GR19BU is a portable monitor with 4K resolution and 144Hz refresh rate
- Monitor delivers sharp visuals and good color performance
- Built-in kickstand allows adjustment at various angles
- USB-C connections handle both power and data
The UPerfect GR19BU is a portable monitor that caters to both gamers and creatives, offering a 19-inch, 4K-resolution panel with a 144Hz refresh rate. Its QLED panel achieves 100% coverage of sRGB and DCI-P3 color spaces, delivering sharp visuals and surprisingly good color performance.
The GR19BU's out-of-box color accuracy averages Delta E 1976 of 1.8 with a maximum of 3.11. It can reach up to 449 nits in brightness, maintaining its color accuracy and offering a respectable contrast ratio of 1,240:1. However, it requires auxiliary power for maximum brightness.
The monitor's built-in kickstand allows adjustment at various angles, and it can attach to a VESA mount. Its thin design and slim bezels make it portable enough to fit into larger backpacks. The GR19BU uses USB-C connections that handle both power and data, reducing cable clutter.
However, the monitor has a cool white point of 8,700K, and its color temperature settings are inaccurate. Its speakers are also weak, struggling to match the monitor's sizable imagery. With a retail price of $540, it is competitive but not cheap.
Compared to desktop-class options, the GR19BU may not be ideal if portability is not a concern. Alternatives include UPerfect's BE173BU and Arzopa Z1RC, which are cheaper and more compact, or Innoview PM408, which is dimmer but much cheaper and still offers vibrant colors and accurate color reproduction.
