Amazon has slashed $300 off LG’s 45GX950A-B UltraGear OLED, a 45-inch 5K2K ultrawide gaming monitor that combines immersive cinema with esport-caliber speed. That price drops to $1,699.99 from $1,999.99, a significant reduction on a high-end display that have been getting the PC-adherent world talking.
If you’ve been waiting for a big-screen OLED that can deliver high-refresh performance, this deal is the sweet spot. With LG’s “Dual Mode” hotkey, you can switch from razor-sharp 5K2K and 165Hz to a blistering 330Hz Wide Full HD preset tailored specifically for competitive play—all while housed within two purpose-built monitors in one chassis.
Big Screen OLED Built for Speed
The 45-inch panel has a steep 800R curve which wraps your field of view around the display, a shape sim racers and open-world fans appreciate for that extra feeling of immersion.
At its native 5K2K resolution (5120 x 2160), that translates into a ton of horizontal space to work with, and fine detail that ensures dense HUDs and fonts, indicators and readout are easier to read. Pixel density is around 124 PPI — higher than a 27-inch 1440p monitor — so text and textures appear clean at their native size.
It’s OLED’s ability to individually light each pixel that is the best bit. As always with OLED expect inky blacks, near instantaneous pixel response (LG tends to quote 0.03ms GtG for these panels) and superb contrast that makes shadowed scenes punch like a boxer. It also has a peak brightness of up to 1300 nits for highlights and VESA’s DisplayHDR True Black 400 certification, which prioritizes deep black levels over sheer full-screen luminance. For gaming in the dark room, that combo is tough to beat.
Color volume on LG’s more recent UltraGear OLEDs has consistently gone close to the full DCI-P3 spectrum, which is one hell of a perk for creators who would prefer their gaming display double as a rich canvas for editing timelines and grading footage. You’re also getting the gamer-first curvature and high refresh tuning that rarely TVs match on the desktop, without the need to run a 42-inch OLED TV as a monitor.
Dual Mode: clarity or 330Hz fighting spirit
Press a hotkey, and the display switches profiles: run graphically intensive games at 5K2K/165Hz for maximum detail, then play another game in native Wide Full HD at an ultra-low-latency 330Hz when every frame counts.
. For players of Valorant, Counter-Strike 2, Apex Legends or iRacing, that high-refresh preset helps minimize perceived blur and input lag — benefits esports pros have been chasing at 240–360Hz for years.
The smooth toggle doesn’t matter, because there are very few GPUs that can push modern AAA (or even esports games) at 5120 x 2160 beyond 120–165 FPS without cranking settings back. Dual Mode allows you to save performance in single-player epics or on a drawn-out project, and then clinch the win in competitive lobbies without having to navigate through drivers panels and game menus mid-session.
Who benefits — and what to watch for before you buy
This is the screen for PC gamers on the higher-end of graphics cards—like, say, playing with a GeForce RTX 4080/4090 or Radeon RX 7900 XTX tier card—who can take advantage of 5K2K at high settings or those who want to be able to switch over to a super-high refresh rate like 330Hz for their twitch shooters.
Steam’s Hardware Survey indicates that most people are still gaming at 1080p, but if you’re building or upgrading to a high-end rig then this panel will scale with you.
Connectivity is geared toward modern PCs, with plenty of video inputs (that usually include DisplayPort with DSC and HDMI for high-bandwidth signals), plus support for variable refresh rate that works with both AMD and Nvidia GPUs. Quality-of-life additions are also present in on-screen control software, Black Stabilizer and crosshair overlays, for tuning profiles per game.
Of course, like any OLED, think about your usage patterns. LG adds some precautions to help prevent image retention like pixel shifting, screen move, logo lumination, and a panel refresh techniques. Just have a screensaver for static desktop work, avoid max-brightness white windows all day and you’ll reduce risk massively. In brighter, sunlit rooms, just be aware that OLED’s full-screen brightness is lower than most high-nit mini-LED monitors but highlight punch and contrast are better in nearly all gaming situations.
Why the $300 price cut is exceptional
And to put that in perspective, ultra-wide OLED monitors at this size and spec already tend to hover around the two-grand mark. Chopping the sticker to $1,699.99 makes it a much better value against upper-end 42–45 inch OLED TVs, while still maintaining most of the gamer-first curve, enhanced native refresh and PC-gamer-centric feature set. Market trackers like Display Supply Chain Consultants have reported rapid increases in OLED monitor shipments as prices are trending downward; offers like this push forward the tipping point from “halo” to “attainable.”
Deal availability can vary, but if you have been waiting to upgrade from a dual-monitor configuration to a single-screen setup—the usable width of this ultra-wide is about that of two 27-inch QHD monitors—this is an appealing time to buy. This is what you pay for that versatility: movie-theater scale for open worlds, productivity-friendly pixel density, a flip-of-a-switch esports mode.
Bottom line: At $300 off, LG’s 45GX950A-B makes a compelling case for one-and-done battlestation upgrades. If you can handle the strain on your GPU, not many displays come close to this combination of immersion, motion clarity and panel quality.
