Acer has unveiled the Predator CG48, an OLED gaming monitor. As its name suggests, the Predator CG48 has a 48-inch panel, making it much larger than most gaming monitors. The Predator CG48 has a 138 Hz refresh rate too, but its high price tag and protracted release date may have some people looking elsewhere.
