Our Verdict
Samsung Odyssey OLED G9/G95SC S49CG95
LG 45GX950A-B
The Samsung Odyssey OLED G9/G95SC S49CG95 and the LG 45GX950A-B are both ultrawide OLED gaming monitors. The main differences between them come down to their sizes and resolutions, as the Samsung is a 49-inch super ultrawide monitor with a 5120x1440 resolution and 240Hz refresh rate. However, the LG is a 45-inch ultrawide monitor, so it's more narrow than the Samsung, and it has a higher 5120x2160 resolution for more detailed images. Although its native 165Hz refresh rate is lower than that of the Samsung, it has a Dual-Mode feature that switches to a 330Hz refresh rate with a lower resolution. This means that choosing one over another comes down to the size and refresh rate that you want. However, the Samsung also has a QD-OLED panel with more vivid colors than the LG.
