Our Verdict
LG 27GR95QE-B
LG 42 OLED Flex
The LG 27GR95QE-B and the LG 42 OLED Flex are different types of OLED displays. The 27GR95QE-B is a gaming monitor with an even higher 240Hz refresh rate than the 120Hz refresh rate on the OLED Flex, and it has a DisplayPort connection, which the OLED Flex doesn't have. On the other hand, the OLED Flex has a larger 42-inch screen that you can bend if you want a more immersive gaming experience with a curved screen. The OLED Flex is a TV with extra features like a built-in smart system and processing.
