Browse source

[Description]
- Enabling SubVP on high refresh rate displays had a side effect
  of also enabling on high bandwidth displays such as 8K60
- However, these are not validated and should be blocked for
  the time being
- Block SubVP on displays that have pix rate > 1800Mhz (includes
  8K60 displays)
