Monitor arms

[413x]

Considering a monitor arm as in future I may want an uw and 4k monitor for separate things (currently just a uw, but not great for photography, great for work)

I'm guessing it's nigh on impossible to get a dual monitor arm for both?
I mean the monitor I have now is 10kg (with stand).

Would it be best to get two?

If it helps, my desk is a sturdy ikea kitchen worktop, but I don't want to damage it

A big online retailer has it's own brand 'basics' monitor arms - which are actually rebranded Ergotrons - I have the rebranded Ergotron LX mounting an Alienware 3418DW

I expect the issue with the dual arm version of the LX might be separating them enough to fit an ultrawide and a 4k monitor in landscape side by side.
If they do fit, then the range of adjustment is likely to be limited, so you might be better off buying 2 of the single arm versions as it only works out to ~£12 more.

I also use an Ikea kitchen worktop as my desk and it seems just fine.

Fantastic.
Think I'll go for a separate arm for each one. Just not worth the risk otherwise
