Scaling problem

[faykus]

I have a 2k monitor. I want to stream in 1080. But when trying to start streaming in such a resolution, the quality of the picture deteriorates greatly. I tried all the ways to scale, everything is soap. Any way out? Or only stream in 2k in 30 fps

PC:

I7 870​

nvidia geforce 1660 super​

16 gb mem​

Monitor: AOC Q2781 2560x1440
