I bought this as a replacement when my monitor got damaged that was the same model. This model although I thought it was the same was slightly different but even better as I can move the screen up and down and there's no light on the back but the build is much sturdier and really easy to put together from the box. Very satisfied with the purchase and delivery which was straightforward and the monitor performs really well. Great value for money for a monitor this size and spec.
