LG Launches in Brazil the UltraGear OLED GX9, First OLED 5K 165 Hz Monitor in the World. With Curved Screen, 330 Hz in Gamer Mode and Brightness of Up to 1,300 Nits, the Model is Geared Towards Gamers and Demanding Professionals.
LG has just taken a bold step in the global monitor market with the arrival in Brazil of the UltraGear OLED GX9, the world’s first 5K OLED monitor with a 165 Hz refresh rate. The launch marks a new era of image quality, performance, and connectivity for demanding gamers, content creators, and multitasking professionals, placing Brazil on the map of the South Korean brand’s priority markets for premium technologies.
With a suggested price of R$ 14,999 and delivery expected from July 15, LG’s monitor surprises not only with its futuristic look but also with its extreme 800R curvature, 45-inch OLED panel with 5K2K resolution, 0.03 ms GtG response time, brightness of up to 1,300 nits, and compatibility with major image synchronization technologies.
The UltraGear GX9 is not just another gaming monitor. It arrives to reinvent the premium segment, offering two usage modes that also make it a powerful ally for those who need screen space and visual quality in high-complexity tasks, such as video editing, 3D modeling, or even productivity in multiple windows.

After decades of failed attempts, Brazil is once again looking to space with an orbital rocket measuring 12 meters, weighing 12 tons, costing R$ 189 million, and scheduled for launch in 2026, in a new race to finally achieve autonomous access to orbit.

Scientists drilled nearly 8,000 meters into the ocean floor above the fault that caused the 2011 tsunami in Japan and discovered that a layer of clay 130 million years old was responsible for making the wave much worse than any model had predicted.
A Curved OLED Panel That Delivers Everything
The star of the show is the 45-inch OLED panel, with native 5K2K resolution (5120 x 2160) and an ultrawide aspect ratio of 21:9. This combination allows a density of 125 PPI, offering sharp definition even on such a wide screen — something essential for both focused gamers and those who work with detailed visualization.
The screen is curved at 800R, creating a deep immersion sensation that “embraces” the user’s field of vision. This curvature is much tighter than average (normally between 1000R and 1800R), ensuring greater visual comfort and engagement during long usage sessions.
Fidelity or Speed? You Choose with the Dual Mode
The UltraGear OLED GX9 allows switching between two operating modes:
- Fidelity Mode: offers maximum 5K2K resolution with 165 Hz refresh rate
- Speed Mode: reduces the resolution to WFHD (2560×1080) and raises the rate to impressive 330 Hz
This feature called Dual Mode is ideal for competitive gamers, who demand the lowest possible response time in fast-paced games, but also for professionals who value a screen rich in details when creating.
Compatibility with Everything — and More
In terms of graphics performance, the monitor delivers VRR (Variable Refresh Rate) with support for NVIDIA G-Sync, AMD FreeSync Premium Pro, and VESA AdaptiveSync, ensuring smooth gameplay, without tearing or stuttering.
The response time is another highlight: only 0.03 milliseconds GtG, one of the lowest values ever recorded, which virtually eliminates any trace in fast action games or fast-paced movies.
The brightness also stands out: it has 275 nits typical, with peaks of up to 1,300 nits in HDR content, ensuring compatibility with the DisplayHDR True Black 400 certification — a standard aimed at deep blacks and extreme contrast in OLED screens.
Professional Colors, Absolute Contrast
The LG monitor covers 98.5% of the DCI-P3 color gamut, making it suitable for professional use in photography, video, graphic design, and color correction. As is typical of OLED panels, the contrast is virtually infinite, as black is achieved by completely turning off the pixels — which also reduces visual fatigue.
This color accuracy combined with motion fluidity places the UltraGear GX9 above conventional IPS monitors, even those of high cost.
Powerful Sound and Plenty of Connectivity
Another unexpected differentiator in a monitor is the sound system: two 10 W stereo speakers integrated, which easily surpass the market average. There is also support for DTS Headphone:X, providing 3D sound even with regular headphones, via 4-pole 3.5mm jack.
Connectivity also impresses:
- 2 HDMI 2.1 ports, with bandwidth of up to 48 Gbps
- 1 DisplayPort 2.1 UHBR10 (40 Gbps)
- 1 USB-C port with 90W Power Delivery – ideal for charging and transmitting video from laptops
- 2 USB-A 3.2 Gen 1 (5 Gbps)
- Picture-in-Picture (PiP) and Picture-by-Picture (PbP) functions, allowing the screen to be divided between two devices simultaneously
This structure transforms the monitor into a true multimedia hub, eliminating the need for adapters or additional equipment to connect consoles, PCs, laptops, and even smartphones.
Ergonomics and Design Worth the Investment
The anti-glare finish, height-adjustable base, rotation, and tilt, and the sober design with gamer details complete the package. Even being a 45-inch monitor, the UltraGear GX9 is relatively light and well distributed — and its curved design maximizes the usable space without requiring a very deep desk.
LG also ensures that the OLED panel has undergone optimizations to prevent burn-in, using technologies like automatic brightness adjustment, pixel shifting, and image retention mitigation.
Pre-Order with Bonuses and Combos
LG has already begun the official pre-order of the UltraGear OLED GX9 on its website, with a suggested price of R$ 14,999. To incentivize early buyers, the brand has launched promotional combos that include auxiliary monitors or LG XBOOM speakers, maintaining the same price as the GX9 sold separately.
Some of the options are:
- LG MyView Smart 27” (model 27SR73U-W)
- LG Ultra UHD 32” 4K (32UR500-B)
- LG XBOOM XL5s speaker
With this, LG bets on a customer loyalty model aimed at premium users, offering added value and complete experience for those building high-performance setups.
The launch of the UltraGear OLED GX9 reinforces LG’s presence at the top of the gaming and professional market, and shows that Brazil is on the radar for cutting-edge releases from the brand. The trend of ultrawide 5K monitors is starting to gain traction, and the GX9 inaugurates a new segment that combines the best of both worlds: extreme performance and absolute image fidelity.
If you are a gamer, streamer, editor, or just a technology enthusiast seeking the best monitor on the market, the GX9 is, today, one of the most complete and ambitious offerings in the world.
