I was looking for at least 1440p at something above 60Hz for that buttery smoothness in games. I was looking at the Acer G-SYNC XB280HK since it was on sale for boxing day down to 549 but on the boxing day advertisement it states its a 4k at 144Hz, even the product page says it but looking into the monitor more i found out it's only 60Hz.
So i'm looking for another monitor that i could get for cheap. Any help would be greatly appreciated :)
Happy Holidays!
ATM there's no 4K monitors with a refresh rate above 60 AFAIK. G-SYNC does make a huge difference to 60Hz without G-SYNC though as far as visual quality and percieved smoothness though compared to a normal 4K monitor.
But 3440x1440 or 2560x1440 at 100-144z will look smoother still.
