The price for that monitor in my country is only 4000 $ ... Prepare to deal with at lest 15ms input latency.
A review for the PA32UCX
"The PA32UCX isn’t a gaming monitor, but 60Hz, FreeSync and the ability to run G-Sync unofficially, means some creatives who are also casual gamers will want to boot up their titles on this pricey 4K display. In the response and lag department, the Asus was a bit sluggish. While it measured similarly to other 60Hz monitors, its control lag was inconsistent. Players spoiled by some of the best gaming monitors
with 144Hz refresh rates will certainly be disappointed when the action gets intense. But if you want to spend some time exploring the game environment, prepare to be mesmerized."
Prepare to be mesmerized .... :P
