Back in May, this monitor was going for $1,399.99, and even at that price, it was positioned as a premium ultrawide. Amazon’s latest cut drops the LG 39GX90SA down to $899 from $1599.99, a massive 44% discount. That’s the lowest it has gone since launch, making it a surprisingly attainable option for gamers that doubles as a full-blown entertainment hub.

What we like about the LG 39GX90SA-W

240Hz refresh rate and 0.03ms response time

OLED technology already has the advantage of near-instantaneous response, and paired with 240Hz, it makes competitive titles feel fluid and responsive with minimal ghosting.

800R curved OLED panel

The 800R curve makes the 39-inch screen feel like it wraps around your field of view. It’s immersive for single-player adventures like RDR2 and practical for multitasking across the ultrawide format.

Smart TV features with webOS24

You get built-in access to Netflix, Disney+, Prime Video, and even cloud gaming services (like GeForce NOW), meaning you don’t need a PC or console attached to use it. It can act as a standalone entertainment screen which is ideal for users that want a more versatile panel.

FreeSync Premium and G-Sync compatibility

Adaptive sync keeps gameplay smooth across both NVIDIA and AMD GPUs, eliminating tearing and stuttering whether you’re on PC or console.

OLED picture quality with HDR True Black 400

With 98.5% DCI-P3 coverage, a 1.5M:1 contrast ratio, and up to 1300-nit peak brightness, it nails deep blacks and vibrant highlights. Games and movies alike benefit from its cinematic color profile.

AI-driven gaming tools

Features like Dynamic Tone Mapping, Black Stabilizer, FPS Counter, and on-screen crosshair add layers of utility for gamers who want precision and customization.

Who is this deal for?

If you’re someone who splits time between competitive shooters and cinematic single-player titles, this gaming display offers the mix of speed and image quality that makes sense. It’s also appealing to people who want an all-in-one display that can stream Netflix and use cloud gaming services like GeForce Now without turning on their gaming PC. That said, we still recommend a powerful gaming rig if you want to push WQHD at 240Hz consistently.

Usually priced at around $1,399.99, this display already had people paying attention, but the current $899 price tag makes it a far more competitive choice compared to other OLED ultrawides. Value-wise, it’s still expensive, but considering the bundled smart features, AI tools, and warranty-backed OLED care, it’s hard to find an alternative that ticks this many boxes.

How the LG 39GX90SA-W performs

In practice, this display is one of LG’s stronger Ultragear entries. The OLED panel brings incredible clarity and contrast, and motion handling at 240 Hz lives up to expectations. The input lag is low, and with adaptive sync, it provides a stable experience across genres for eSports experiences like Valorant to more cinematic titles – which benefit from its beautiful contrast and stunning resolution.

The tradeoff is that sharpness can’t quite match smaller 4K panels, so if text clarity is your main concern, you might notice the difference. But for gaming and entertainment, it delivers and has our recommendation.
