LG’s 45-Inch OLED Ultrawide Delivers Big-Screen Gaming Without the 4K Performance Hit
Ultra-wide gaming monitors continue to grow in size, but higher resolutions often demand increasingly powerful hardware. LG’s latest Prime Day deal offers a different approach: a massive 45-inch OLED display that retains a relatively manageable 3440×1440 resolution. The LG UltraGear OLED 45GX900A-B is currently available for $884.99 during Prime Day, nearly half off its original retail price.
A Bigger Screen Without a Bigger GPU Requirement
Unlike large dual-4K or 5K ultrawide displays, the 45GX900A-B sticks with a 3440×1440 ultrawide resolution—the same pixel count found on many 34-inch gaming monitors.
That means gamers get:
- A huge 45-inch display
- An immersive 800R curved OLED panel
- Less demanding graphics requirements than 4K ultrawides
The larger physical size creates a far more immersive experience without dramatically increasing the workload on your graphics card.
Fast OLED Gaming Performance
The monitor combines its OLED panel with gaming-focused specifications, including:
- 3440×1440 ultrawide resolution
- 240Hz refresh rate
- Fast OLED response times
- 800R aggressive curve
These features make it well suited for fast-paced multiplayer titles while also delivering the deep blacks and vibrant colors OLED technology is known for.
Useful Beyond Gaming
Although designed primarily for gaming, the UltraGear also offers respectable productivity features.
Connectivity includes:
- HDMI
- DisplayPort
- USB-C
- USB-A hub ports
The USB-C connection supports up to 65W Power Delivery, allowing many productivity laptops to connect with a single cable for video, charging and peripherals. While that isn’t enough power for most gaming laptops under heavy load, it’s sufficient for many ultrabooks and office systems.
Prime Day Pricing
The Prime Day promotion drops the monitor to $884.99 for Amazon Prime members.
Buyers without Prime aren’t left out, however. Both LG’s online store and Best Buy are offering nearly identical pricing at $899.99, making the discount widely available.
Who Should Buy It?
The 45GX900A-B is best suited for gamers who want a dramatic OLED ultrawide experience without investing in the GPU horsepower required for higher-resolution displays.
Users with top-tier graphics cards who want maximum pixel density may instead prefer LG’s higher-end 45-inch 5K2K OLED model, which is also currently discounted. For everyone else, this 45-inch 1440p OLED strikes an appealing balance between immersion, performance and value.
