Deal | 39-inch 240Hz LG OLED gaming monitor with smart TV apps is $800+ off in Amazon sale

When short on space, an OLED gaming monitor that doubles as a smart TV becomes a tempting proposition. The curved 39-inch LG Ultragear still occupies a large footprint, but rewards owners with its versatility. Like other WOLED panels, the 39GX90SA also offers deep blacks and stutter-free gaming.

The LG monitor is at a new low Amazon sale price of $775.51, an over $800 discount from its April 2025 launch MSRP.

A unique but understated design

Besides its imposing size, the aggressive 800R curve of the OLED monitor draws immediate attention. Buyers should ensure they have adequately deep desks to accommodate the display. Most users otherwise find its design unassuming, with a style that blends in with office decor.

In an ideal setup, gaming becomes much more immersive. More titles now support a 21:9 aspect ratio, but the 39GX90SA especially entices fans of racing and flight sims. The maximum 240Hz refresh rate and low latency make fast-paced driving or flying seem even more realistic. Even without a PC or console, players can experiment with Xbox Cloud Gaming or GeForce Now.

The LG monitor’s 3440 x 1440 WQHD resolution will be an upgrade for many buyers. Still, at 39 inches, a lower pixel density than 4K alternatives produces some drawbacks. PC World is one of several reviews that note how text may not look as sharp as expected.

Competing OLED monitors have a brightness edge

WOLED technology isn’t quite as vivid or bright as rival QD-OLED panels from Samsung. Nevertheless, testers discover that the 39GX90SA retains its advantages over IPS options. Contrast levels are higher than mini LED models, while DisplayHDR True Black 400 expands wide color palettes.

Ultimately, it’s an OLED gaming monitor that excels more with entertainment than productivity. At the display’s new rock-bottom Amazon sale price, smart TV capabilities are what add to its value. WebOS support means that popular apps like Netflix and Disney+ are accessible with a remote control. However, input changes and navigation can be sluggish.

If this $775.51 LG OLED monitor deal sells out on Amazon, Best Buy has it in stock for $800, which is still a steep discount.
