Our Verdict

Corsair XENEON FLEX 45WQHD240

LG 45GX950A-B

The LG 45GX950A-B and the Corsair XENEON FLEX 45WQHD240 are both 45-inch ultrawide OLED gaming monitors. The main difference is that the LG has a higher 5k2k resolution, so images are sharper and more detailed. Although the LG has a lower 165Hz native refresh rate than the 240Hz on the Corsair, it has a Dual-Mode that switches it to a 330Hz refresh rate with a 2560x1080 resolution. The LG also has other advantages, like the fact that it gets brighter, has lower input lag, and supports DisplayPort 2.1 bandwidth.
