It's a limit of HDMI 2.0
https://en.wikipedia.org/wiki/HDMI#Main_specifications
Max. TMDS character rate : 600MHz.
As I've said, 3840x2160@60 runs at 594MHz, but 5120x2160@60 will be somewhere north of 670MHz even ignoring blanking.
You might just about get 50Hz to work (5120x2160*50 = 552MHz), but again depends on blanking periods.
HDMI2.1 allows you to exceed that, but is a totally different interface at the physical layer.
