Amazon Basics Monitor Hub Arm Mount Aluminize Silver £46.28 with voucher @ Amazon

Same here, the Basics one even came with Ergotron instructions if I remember correctly.

Look into VESA height adjustment adapters. They're not expensive.

Something like these maybe?

Also VESA extender plates are worth having a look too.

This person here has had good luck using the extension plates with I think the same problem you're having.

You can buy 2 separately and the code still works, just tried it.

In my situation I have a floating desk with no legs that I've secured to the wall with "L-Brackets", so because of this I can't move the desk back and forth like a normal desk. I only got a small gap from the back of the desk to the wall for cables to run through, and therefore the "Amazon basic monitor arm" was annoying to use because the back plate screws were in an annoying place, where as the "Invision arm" uses a screwless method making it more easier/versatile to use, so I can put the clamp in any tight place I like, without having to take the desk of the wall. Also I must say both clamp down well once they're clamped to the table they don't move, I just like the "Invision arm" due to it being more versatile but I think the "Amazon arm" handles more weight 11kg compared to 9kg from Invision, my screen is roughly around 4kg I believe so this wasn't an issue for me, so I also suggest seeing how much your monitor weighs.

This is an image of how the Invision clamp works. Hope that helps

Personally I'd get 2 of these, they're more versatile with monitor sizes and positions. I use 2 of them, one with a 34in ultrawide and the other with a 27in 1440p monitor

Yes, I use one with my Dell S3422DWG 34in Ultrawide

As mentioned by others this Amazon mount is equivalent to/the same as the Ergotron LX Desk Monitor Arm here: ergotron.com/en-…241

There's also a link to a compatibility checker on that page.

the inch size is irrelevant and missleading. Weight is what matters.

Have you watched the Ergotron LX video here in case you've missed an adjustment?

The price has dropped to £49.15. It is actually £29.49 after the voucher is applied. I have just bought one.
