Deal hunters looking for a big, fast OLED gaming display may want to move quickly. The LG UltraGear 39GX90SA-W, a 39-inch curved ultrawide OLED gaming monitor, is currently showing a steep 51% price drop on Amazon, bringing it down to about $784 for a limited time. The promotion applies to both Prime and non-Prime shoppers, but pricing and availability can change at any moment.
A standout feature here is the mix of size, speed, and immersion. The 39-inch ultrawide panel runs at 3440 x 1440 (WQHD) and pushes a 240 Hz refresh rate, making it a strong fit for fast-paced PC gaming where smooth motion matters. It also uses an aggressive 800R curvature designed to wrap the screen around your field of view for a more enveloping experience. For some setups and preferences, that curve may feel intense, but for immersive titles it can be a major plus.
Because it’s an OLED, the monitor leans into the strengths people buy OLED for: deep blacks, strong contrast, and very quick response behavior that helps reduce blur during action-heavy gameplay. Color performance is solid as well, with reported coverage around 96% of the DCI-P3 color gamut. Brightness, however, is a familiar trade-off for this type of panel technology versus some alternatives. The display is said to reach roughly 247 nits in a full-screen window and up to about 784 nits in a smaller 10% window, which is usable for many rooms but may not satisfy anyone who prioritizes maximum brightness above all else.
There are a few drawbacks worth knowing before buying. Pixel density comes in at roughly 94 PPI, and that shows up most in everyday desktop use. Text clarity is described as a weak point, which can matter a lot if you plan to use this monitor for long hours of writing, spreadsheets, coding, or reading. In other words, it’s positioned more convincingly as a gaming and entertainment display than a productivity-first screen for sharp fonts.
Connectivity is one of the monitor’s stronger practical perks. It includes dual HDMI 2.1 ports and DisplayPort 1.4 for modern gaming PCs and consoles. It also offers USB-C with DisplayPort support and up to 65W power delivery, plus two USB Type-A ports, an Ethernet port, and a headphone jack, giving it flexibility for mixed setups.
Another feature that helps it stand out in search for people who want a “monitor + TV” hybrid: it includes LG’s webOS smart platform. That means you can use built-in smart TV functionality without relying on a PC, which can be especially convenient for bedrooms, dorms, or multi-purpose gaming spaces.
At its current pricing, the LG UltraGear 39GX90SA-W looks like a compelling value for buyers who want a large ultrawide OLED gaming monitor with a very high refresh rate and smart TV features. Just keep the text clarity and aggressive curve in mind, since those will be deal-makers or deal-breakers depending on how you plan to use it.
