Our Verdict

LG 45GR95QE-B

LG 42 OLED Flex

The LG 45GR95QE-B and the LG 42 OLED Flex are different types of OLED displays. The 45GR95QE-B is a gaming monitor with an even higher 240Hz refresh rate than the 120Hz refresh rate on the OLED Flex, and its ultrawide screen provides a more immersive gaming experience. The 45GR95QE-B has a fixed 800R curve, but the OLED Flex has a bendable screen that you can customize from a flat screen to a 900R curve. The OLED Flex is a TV with some extra features like a built-in smart system and processing, while the 45GR95QE-B has a DisplayPort connection.
