A May 11, 2026 deal post by htp182 said LG’s 39-inch UltraGear 39GX90SA-W OLED gaming monitor was on sale through Amazon for $749.99. The reported offer was below the monitor’s $1,599.99 suggested retail price.
The monitor combines a 21:9 ultrawide OLED panel, a 3,440 x 1,440 resolution and a pronounced 800R curve. LG specifies a refresh rate of up to 240Hz.
Display specifications and tradeoffs
The 39-inch screen spreads the same number of pixels over a larger area than a 34-inch ultrawide at 3,440 x 1,440. That produces lower pixel density, with less fine detail in small text and interface elements. A 32-inch 4K display has higher pixel density, while a 45-inch ultrawide at the LG’s resolution has lower density.
LG lists a 0.03-millisecond gray-to-gray response time and support for AMD FreeSync Premium and NVIDIA G-SYNC Compatible adaptive synchronization. The company says achieving support for the maximum 240Hz refresh rate requires a graphics card supporting DisplayPort 1.4 or HDMI 2.1.
LG advertises peak brightness of up to 1,300 nits at a 1.5% average picture level. This is a conditional peak specification, rather than a rating for sustained brightness across the entire screen.
The monitor’s physical size presents a separate limitation. Its curved panel and large stand occupy substantial desk space, making screen placement and viewing distance relevant alongside resolution.
Connections and smart features
Video connections include two HDMI 2.1 ports, DisplayPort 1.4 and USB-C with DisplayPort input and up to 65 watts of power delivery. The monitor also includes two USB-A 2.0 ports, Ethernet and a 3.5-millimeter audio output.
Built-in webOS provides access to streaming applications and cloud gaming services. LG notes that an internet connection is required and that subscriptions or separate payments may be necessary for individual services.
OLED care and warranty
LG’s owner’s manual warns that displaying a still image for a prolonged period can damage the screen and leave a retained image. LG also says the model includes OLED Care functions such as pixel cleaning.
LG lists a two-year limited warranty for parts and labor for the U.S. model. The company directs owners to the warranty information supplied in the product packaging for detailed coverage terms.
