Our Verdict
Acer Predator X27 bmiphzx
Acer Predator X27U bmiipruzx
Although they share similar names, the Acer Predator X27 bmiphzx and the Acer Predator X27U bmiipruzx are different types of monitors. The X27 is a 4k, 144Hz monitor with native G-SYNC support, while the X27U is a 1440p, 240Hz monitor, so they're aimed at different types of gamers: the X27 is better for playing detailed games with NVIDIA graphics card, and the X27U is better for high refresh rate gaming. On top of that, they deliver different picture quality as the X27 is LED-backlit, allowing it to get brighter, while the X27U has an OLED panel, so it displays deeper blacks.
