Our Verdict
ASUS ROG Swift OLED PG32UCDP
LG 27GX790A-B
The ASUS ROG Swift OLED PG32UCDP and the LG 27GX790A-B are OLED gaming monitors with maximum refresh rates of 480Hz. The ASUS is the more versatile option, as it can also display a 4k @ 240Hz signal on its larger 32-inch display. However, the LG is a better option for dedicated esports gamers, as you can reach its 480Hz maximum refresh rate at a higher 1440p resolution.
