yes i have 3 monitors and 1 is a ROG swift, then i bought the samsung UHD 39" for only about 400$. and oh my gawd is it beutiful. I would suggest a IPS 4k for your purpose and a 4k TN for gaming.
Are 4K monitors good for graphic design and movie editing?
I hear that a large 4k screen is great for video editing; you benefit from being able to work with 4 1080p images at the same time, rather than a single one. You need a beefy GPU for it though, but you would need one anyway when you're video editing.
