Thanks! Do happen to know the difference in the LG UD69P and the LG UD58B?

Bigger number = newer model?

I'm playing on Xbox one X and both LG monitors only has FreeSync on DisplayPort.

PS - I'm still confused on what FreeSync is (wiki wasn't much help) but I understand the XB1X will at sometime have a firmware update to support FreeSync.
