an515-45 upgrade to 4k screen problems

Hi all, upgraded the 1920/144hz panel in my an515-45 to a 4k/ 12OHZ  (NE156QUM-NZ3) And am having a few issues.

It really struggles to run at 120hz - it flickers & ghosts, especially with movement on the screen, eg max/min windows. I can get it to stabilise if I change it to 60hz and it will work well, but upon startup it will flicker again even if set to 60. I can stabilise it by changing to 120 then changing back to 60.  I have updated all my drivers & software.

Could it be the bandwith of the cable ? the FDH/144hz uses eDP 1.4/HBR2(5.4g/lane) but the UHD 120hz uses eDP 1.4/HBR3 (8.1g/lane)
Is there a different cable reqd for a UHD panel, and if so, will this one (50.QBAN2.005 - for predator g9-791/2/3 )  be compatible with mine?
Any advice would be greatly appreciated :)
