Currently usin BenQ GW65HT QHD 27" 60HZ IPS

and I want to upgrade it, Im thinkin that the predator xb271hu is perfect for me but the 4k is somethin that i wanna try .

So ,

Thtas a huge difference in size. While im preaching people should be getting bigger. I think 40" is too big for normal monitor distance.
Im on 32" and its a very minor glance to focus on the corners, with 40" i was moving my head around.

Id be looking at 32-34. 27" is too small.
