Ergotron HX Desk Reviews

Great product; instructions not the most beginner-friendly

I mounted a 48" OLED on my standing desk with this product. It exceeds my expectations; there is basically no wobble when using the standing desk, and my OLED TV feels very stable. I highly recommend the product and B&H Photo. I found the printed instructions to be less detailed than I had hoped, though this was my first time using an Ergotron. I got a better sense by watching installation videos online and using AI to make sure I was following the steps correctly.

Use Amazon Instead

Do not order this item. It was purchased on 4/3, today is 4/21 and there has still been no shipping confirmation. Order it from Amazon instead. It came in 2 days. I wanted to support a business other than Amazon but I am deeply regretting it. Talk about a self inflicted headache. I sent a message to C/S to cancel this order who advised they couldn’t guarantee it will be canceled. Despite no movement in 18 days. What a joke. I will never purchase from B&H again. Stay away!!

Is it possible to transform this desk mount into wall mount if needed?
Asked by: Harry
No, the surface mount is a Clamp for 0.4 to 2.59" Desk/Counter Tops. It needs a surface to clamp on to. For mounting to a flat surface, you would need the Ergotron HX Wall Mount Monitor Arm.
