LG’s latest Ultragear OLED gaming monitor is built for people who want one screen to do almost everything. The 39-inch LG 39GX90SA blends a high-refresh ultrawide gaming display with built-in smart TV features, creating a flexible setup for smaller rooms, apartments, or any desk where you’d rather not juggle a separate television.
Right now, it’s hitting a new low sale price on Amazon at $775.51, which is a dramatic drop from its April 2025 launch MSRP. If that price disappears, it’s also available at Best Buy for around $800, still far below its original asking price.
A big ultrawide that doesn’t look flashy, but demands desk space
At first glance, the monitor’s design is fairly understated for a gaming product, making it easy to fit into an office or mixed-use room. The real attention-grabber is the aggressive 800R curvature. That deep curve is designed to pull the edges of the 21:9 screen closer to your field of view for a more immersive experience, but it also means you’ll want a deeper desk than usual to place it comfortably.
Built for ultrawide gaming, especially racing and flight sims
This 39-inch OLED monitor is at its best in games that support the 21:9 ultrawide aspect ratio. It’s an especially good match for racing games and flight simulators where peripheral vision and cockpit-style immersion matter. With a refresh rate up to 240Hz and low input lag, fast motion looks smooth and responsive, which is exactly what competitive and high-speed players want from a modern OLED gaming display.
And because it’s also a smart platform, you’re not limited to a PC or console. The monitor supports cloud gaming options like Xbox Cloud Gaming and GeForce Now, making it possible to play even when you don’t have a dedicated gaming rig hooked up.
WQHD resolution looks good, but pixel density is a trade-off at 39 inches
The 39GX90SA runs at 3440 x 1440 (WQHD ultrawide), which will be a meaningful upgrade for many buyers coming from standard 1080p or older ultrawide displays. That said, at 39 inches, the pixel density isn’t as tight as a 4K screen, and some reviews point out that smaller text may not look as crisp as you’d expect, especially if you’re doing lots of reading, spreadsheets, or long work sessions.
Brightness isn’t class-leading, but OLED contrast still shines
Like other WOLED panels, this LG ultrawide delivers the kind of deep blacks and contrast OLED is known for, giving games and movies a richer look than typical IPS displays. However, WOLED generally can’t match the peak brightness and punchier highlights seen on some QD-OLED alternatives. Brightness here is described as average, though the monitor still outperforms many non-OLED options in perceived contrast and black levels. It also supports DisplayHDR True Black 400, which helps with darker scenes and wide color reproduction.
More of an entertainment powerhouse than a productivity monitor
Where the 39GX90SA separates itself from many competing OLED gaming monitors is its smart TV functionality. With webOS on board, you can use popular streaming apps like Netflix and Disney+ directly on the monitor, controlled with a remote. That’s a major value add for anyone who wants a single screen for gaming at a desk and streaming from bed or a couch.
The trade-off is that smart TV style interfaces aren’t always as snappy as a simple monitor menu. Some users report that navigation and switching inputs can feel a bit sluggish, which is worth keeping in mind if you constantly bounce between devices.
For anyone hunting for a large curved OLED ultrawide with 240Hz gaming performance and built-in streaming apps, the current $775.51 sale price makes this LG 39-inch Ultragear one of the more compelling “monitor plus smart TV” hybrid deals available. Prices and availability can change quickly, so the discount may not last.
