Only way to know is give it a try, the CPU is definitely not the bottle
neck. The NVidia GEForce GT 710 released 2014 has a PCIe 2.0 x 8 bus
and is limited to a resolution of 1280x720 according to
(https://www.techpowerup.com/gpu-specs/geforce-gt-710.c1990)

Could there be a bus incompatibility? ASUS X570-Pro has a PCIe 4.0x 16
bus?

From experience with an older Zotec connected to a 4k TV, anything over
1080p causes the video to act liked Mr Zenwiz describes.
