The S400z all-in-one features a gorgeous design that's both slim and trendy. The design is considerably thinner than previous generations and includes a grill-ventilation in the rear, allowing it to run cool and quiet. Plus, it comes with two stand options for either the frame or monitor. Or you can use the VESA mount, which supports hanging your S400z on the wall. The 21.5-inch display delivers a resolution of 1920 x 1080 with 250 nits, so all of your images and videos look vibrant and crisp.
