Score Breakdown
A Visual Feast and Gaming Powerhouse
The LG 45GX950A-B Ultragear monitor consistently earns high praise for its exceptional picture quality. Owners frequently describe the OLED panel as delivering stunning colors, deep blacks, and amazing contrast, making everything from gaming to productivity tasks look fantastic. Many users coming from older monitors report a “night and day” difference, finding the visual experience transformative. The matte screen finish is generally appreciated for minimizing reflections, which is particularly beneficial given the monitor's aggressive curve. The monitor’s 45-inch 5K2K display and 800R curvature are lauded for creating a highly immersive experience. Several owners initially found the curve dramatic but quickly adapted, describing it as natural and effective in pulling them into games. This expansive screen real estate is also a significant advantage for productivity, allowing users to comfortably manage multiple applications simultaneously. For gaming, the monitor's performance is consistently described as excellent. Its high refresh rate of 165Hz (with an overclocked 330Hz dual mode) and ultra-low 0.03ms response time contribute to incredibly smooth motion and instant feedback, making it a standout choice for various game genres. Compatibility with NVIDIA G-Sync and AMD FreeSync Premium Pro further enhances the fluid, tear-free gaming experience.
Connectivity, Hardware, and Practicality
In terms of build and ergonomics, the monitor receives solid marks. Owners appreciate the premium feel and sturdy stand, though some note the stand's tilting mechanism could be more robust. The monitor offers a good range of connectivity options, including two HDMI ports, one DisplayPort, and a USB-C port that provides 90W power delivery, which is a convenient feature for laptop users. Automatic input switching is a welcome addition that many users find enhances convenience. However, the monitor's demanding nature is a recurring theme: multiple owners emphasize the necessity of a very powerful, high-end GPU to drive games at its native 5120 x 2160 resolution and high refresh rates without significant performance compromises. While the built-in speakers are not universally praised, several users found them surprisingly adequate for everyday use, with some even replacing their external speakers.
Areas for Improvement and Reliability Concerns
The monitor’s software and user interface are a significant point of criticism, receiving weak scores from owners. Many describe the controls as clumsy and user-hostile, with the menu system often deemed an “embarrassment” for a product from a major manufacturer. Common complaints include unresponsive joysticks, aggressive auto-power off prompts that interrupt active use, and frustrating input switching behavior that often defaults back to a previous source. The “image cleaning” prompts are also seen as intrusive. Reliability and durability also present some concerns. Several buyers reported receiving units with initial pixel issues or vertical lines that required running the “pixel cleaning” function to resolve. Concerns about OLED burn-in are prevalent, with owners expressing dissatisfaction over vague warranty information from LG regarding this issue. Some users also reported issues with the monitor randomly shutting off after a short period of use or struggling to come out of sleep mode. Additionally, the dual mode resolution scaling is noted by some as being poorly implemented, and the included DisplayPort cable is often cited as not being DP 2.1, potentially requiring an upgrade for optimal performance with high-end graphics cards. The KVM feature is also described as limited, relying on network connectivity rather than being a true hardware KVM.
Conclusion
Despite its software shortcomings and the demanding hardware requirements, the LG 45GX950A-B Ultragear stands out as an outstanding display for those prioritizing an immersive, high-performance visual experience. Its stunning OLED panel and expansive, curved screen create an unparalleled environment for gaming and productivity. While the user interface and some reliability aspects could be improved, the core display technology and gaming capabilities are exceptional. Buyers prepared to invest in a powerful PC and willing to navigate the monitor's quirks will find it offers a truly premium and transformative visual experience.

What owners actually said
“I wanted a wide screen 5k2k. The picture on this is very good. The curve takes some getting used to but at 45” the curve helps. Works fine with my MacBook Pro through a DisplayPort adapter. I tried the HDMI port but couldn’t get full resolution.”
“This monitor worked flawlessly out of the box. Received this week, time will tell, but, for now...thanks Amazon for the deal. Would recommend.”
“Great screen only issue is waiting for it to turn on once computer goes into sleep mode. Takes 20-30 for it to come back on once you start it.”
