The ARCTIC W1A monitor wall mount is suitable for monitors up to 43 inches and supports a maximum load of 20 kg. The Samsung G3 Odyssey 27 inch monitor should be compatible as it is within these size and weight limits. However, it is important to check the VESA mounting requirements of the monitor to ensure that it is compatible with the mount. The W1A supports 100 x 100 mm and 75 x 75 mm VESA mounts.
