If I connect this to the USB-c input of LG Ultrafine 5K Display can I use my MacBook Air (13-inch, Early 2014)
I know the MacBook Air (13-inch, Early 2014) which is only TB - and would not expect full 4k - but need a new monitor and want to future proof as laptop will be replaced by new Air or Pro later this year
Alternative is something like LG 27UD88-W, but like the idea of improved potential resolution and webcam

The MacBook Air (13-inch, Early 2014) has the first generation of Thunderbolt and allows only 10 Gbps.
I believe 5K 5120 x 2880 @ 60 Hz requires more than 20 Gbps (almost 23). This will only work with Thunderbolt 3.
4K 3840 x 2160 @ 60 Hz requires more than 10 Gbps (almost 13). This will work with Thunderbolt 2 or later according to the document HT207448 "Use the LG UltraFine 5K Display with your Mac".
That document mentions a supported 3200 x 1800 @ 60Hz mode which I believe is less than 10 Gbps but it says that mode allows the display to work with the Mac mini (Late 2014) which has Thunderbolt 2 ports.
The document does not mention any Thunderbolt 1 Macs which should allow 2560 x 1440 @ 60 Hz, so I don't know what will happen in that case with the LG 5K display. I have read one review where 4K @ 30 Hz did not work on a Mac that had Thunderbolt 1.
