The Gigabyte M28U monitor is 28 inches in size, while the monitor mount is designed for a maximum of 25 inch monitors. The monitor is therefore not compatible as it exceeds the maximum monitor size of 25". In addition, the mount is designed for VESA 75x75 mm or 100x100 mm; the M28U generally supports VESA 100x100 mm, which fits, but the size restriction remains the deciding factor. The maximum payload of 16 kg is no problem for the M28U at around 6-7 kg.
