I have an external LG 27GN800 monitor capable of 4K (works fine on Mac) that when connected to my Framework DIY is only able to get a max resolution of 2560 x 1440. I’ve tried both DisplayPort to DisplayPort, and also via DisplayPort to USB-C. I’ve read in other forum posts that DP connections should be good up to 5K, so the graphics card should not be the issue. Is there an updated driver I need? Issue with Linux Mint? Thanks!

Well, I’m a moron. But, in my defense, I’m bad with numbers, and everything on the display is literally twice as large than when I connect the Macbook. Perhaps I have some sort of 2x zoom on or something.

It’s a Quad HD, so can be misinterpreted, I would dream of saying misrepresented 
1440p / QHD / QuadHD / WQHD is :-
2560×1440 pixels
It is a limitation of the USB to DisplayPort adaptor, get one of these perhaps.
