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.

I'm looking at a BenQ 32" monitor (the EW3280U) and it falls just below the minimum suggested weight of this arm - roughly 16 lbs vs the 20 lbs min...) Is this monitor just too light for the arm to support it properly? I've seen other comments about the LX being too wobbly, and I'd really a mount that's rock solid.
Asked by: Daniel
I would recommend to stay within the manufacturers recommended weight range.

I can't speak to the XDR Pro, but I've been using an IKEA Bekant standing desk with this arm and a Dell U3818DW without issue for ~2 years years now.
