MacBook Air 2015 - Dual Monitors

Hi,

I am hoping someone can help me please.

I have a 2015 MBA with one ThunderBolt 2 port. I currently can not stretch to upgrading my laptop now, plus it doesn't seem worthwhile given how well it still runs. I currently run my laptop on one monitor and would love it if I could have it linked to two.

I've looked online at the Belkin Express Dock, some people are complaining about it not fully working. I've also looked at the StarTech external USB graphics cards, other people are having issues with the software since Big Sur came out.

Does anybody have any other options? or is anyone using the above and would recommend it?

Thank you in advance.
