If you’ve been waiting for a truly massive OLED gaming monitor that can pull double duty for work and content creation, LG’s 45-inch UltraGear 45GX950A-B (GX9 series) just became a lot more tempting. The ultrawide 5K2K display is currently discounted by about 35% on Amazon, slicing roughly $700 off the usual price and bringing it down to around $1,299 for a limited time.
What makes this LG UltraGear stand out is the combination of size, resolution, and OLED image quality. You’re getting a 45-inch ultrawide screen with a 5120 x 2160 (5K2K) WUHD resolution. That’s a big upgrade in sharpness compared to standard WQHD ultrawide monitors, landing at about 125 PPI. While it won’t satisfy people who demand ultra-high pixel density for razor-sharp desktop text at close range, it’s a strong fit for immersive gaming, media consumption, and creative workflows where the extra canvas and OLED contrast matter most.
Immersion is clearly the goal here, and LG leans into it with an aggressive 800R curvature. For many gamers, that curve helps wrap the image around your field of view and makes open-world titles, racing games, and flight sims feel more enveloping. Still, if you prefer flatter screens for spreadsheets or precise design work, the curve may feel like “too much,” so it’s worth considering your setup distance and typical usage.
Performance is another highlight. At the monitor’s full 5K2K resolution, the refresh rate tops out at 165 Hz. If you’re chasing maximum speed for competitive play, the monitor can also run at a lower WFHD mode to reach up to 330 Hz, giving fast-paced shooters the buttery motion clarity many esports-focused players crave.
OLED fans will appreciate the usual advantages: inky blacks, near-infinite contrast, very fast response times, and no blooming around bright objects. Color reproduction is also a major selling point here, with reports praising strong color accuracy even without calibration, which is a nice bonus for anyone who edits photos or video in addition to gaming.
Brightness is one of the few areas where some buyers may hesitate, and it’s a familiar OLED trade-off. Full-screen brightness is modest, with the panel peaking around 270 nits in a 100% window. HDR can hit much higher peaks—up to about 1,000 nits—but only in very small highlights (around a 2% window), meaning HDR “pop” is most noticeable in small bright elements rather than across the entire screen.
Another practical win: unlike some QD-OLED displays that can raise concerns about text fringing, text clarity reportedly isn’t a major issue on this WOLED panel. That makes this monitor more comfortable as an all-day display for mixed gaming and productivity, as long as you’re okay with the pixel density and curve.
For connectivity, LG includes a solid selection geared toward modern GPUs and multi-device setups:
Dual HDMI 2.1
DisplayPort 2.1 (UHBR10)
Two USB 3.2 Gen 1 Type-A ports
USB 3.2 Gen 1 Type-C with DisplayPort support and up to 90W power delivery
3.5mm audio jack
At its current discounted price, the LG UltraGear 45GX950A-B delivers a compelling combination of ultrawide 5K2K resolution, OLED contrast, high refresh rates, and strong connectivity. It’s especially appealing for gamers who want a big, cinematic display that can also handle serious multitasking. The main compromises are the aggressive 800R curve, the relatively modest brightness typical of OLED in full-screen scenes, and a pixel density that’s good—but not class-leading—for a display this large.
