LG UltraGear at the 2023 International CES showed off the world's first gaming monitor with a blistering fast 240 Hz OLED panel. An in-house development by LG Display, the LG UltraGear OLED 45GR95QE is a 45-inch ultrawide gaming monitor with a 21:9 aspect-ratio, 3440 x 1440 pixels native resolution, an 800R curvature, and a surreal 240 Hz refresh rate with 0.03 ms response time. It supports both G-SYNC and FreeSync Premium to help it twiddle its thumbs while it awaits new frames from your GPU. The display takes input from HDMI 2.1, and features a high-performance DAC + headphones amplifier along with support for DTS Headphone X. For these and more, the monitor bagged a 2023 CES Innovation Award.
 
A great monitor that is probably going to have a steep price.
