That's also my setup, the external 4k monitor is roughly the same scale as my FHD laptop. I did this on purpose, to avoid having to mess around with scaling and just run everything at 100%. But more and more laptops start having higher resolutions nowadays, and using my external screen at a scale of more than 100% would be a waste. But a 3-4k 14" laptop at 100% would be unusable.
