Review on 💪 Enhance Your Monitor Setup with Gladiator Joe Monitor Arm/Mount - VESA Adapter Extension by Jayme Newitt

In fact, you can only raise or lower the monitor. I was planning to use it horizontally but there are problems. If you mount it on a hand that also rotates (landscape to portrait) it doesn't work uselessly, there is a way to lock your hand to prevent rotation. The mount itself is very heavy. It's not aluminum, it's heavy steel. The added weight of a horizontally shifted monitor is too much and it rotates to landscape. Make sure your monitor arm doesn't rotate, otherwise it will only work to raise or lower. Don't move horizontally
