The HP Adjustable Dual Display Stand means that you can use two displays to maximize your productivity & optimize efficiency. Either or both displays can be rotated to landscape or portrait orientation, & the stand is depth-, height-, tilt-, & angle-adjustable so you can view both screens at eye-level as well as slightly facing each other, letting you track multiple applications & information sources at the same time. Integrated base rollers let you rotate the stand so you can more easily share your work.
