Design
The Samsung Odyssey OLED G81SF maintains the premium aesthetic of the Odyssey line while delivering a sleek, modern look. The monitor features a metal construction from base to neck, providing both stability and a high-end appearance.
What immediately stands out is the fragile panel and minimal bezels, which maximize screen real estate while maintaining a sophisticated profile. The monitor assembles easily with just a few screws connecting the base, neck, and display.
Adjustability ranks high with smooth height, tilt, and swivel movements that help users find their optimal viewing position. The stand feels sturdy with no noticeable wobble during use.

The back of the monitor houses Samsung’s signature RGB lighting ring powered by CoreSync and CoreLighting+. This customizable lighting adds a touch of flair without being overwhelming, fitting well with most gaming setups.
Port selection includes two HDMI ports, one DisplayPort, two USB-A ports, one USB-B upstream port, and a 3.5mm headphone jack. This configuration works well for multi-console gaming setups and allows for picture-in-picture functionality. However, the lack of USB-C connectivity feels like a significant oversight in 2025, especially at this price point.
A responsive joystick control sits among the ports, providing intuitive navigation through the on-screen display. The menu system feels snappy and well-organized, making adjustments quick and painless.
Features
The Samsung Odyssey OLED G81SF offers a focused feature set that prioritizes display quality and performance over additional bells and whistles.
The standout feature is Samsung’s Safeguard+ Dynamic Cooling System, which addresses one of the main concerns with OLED panels: maintenance and longevity. This system employs a pulsating heat pipe that actively releases coolant, providing significantly better thermal management than traditional graphite solutions.
Working alongside the hardware cooling is an intelligent Thermal Modulation System that uses algorithms to fine-tune brightness and heat levels in real-time. The monitor also includes Logo & Taskbar Detection, which subtly adjusts luminance in static screen areas to prevent image retention.
During two weeks of testing, I never encountered a single prompt to perform maintenance or power down the display—a refreshing change from other OLED monitors that often interrupt gameplay for pixel refreshes.
Gaming-specific features include customizable crosshair overlays for shooter games and picture-in-picture capabilities for viewing multiple inputs simultaneously. Color calibration options allow users to fine-tune the display to their preferences.
What’s missing, however, is the robust feature set found in similarly priced monitors. There’s no KVM functionality for controlling multiple devices with one keyboard and mouse—a feature that would benefit streamers and content creators. Additionally, the monitor lacks integrated speakers and Samsung’s Smart TV functionality found in other Odyssey models.
Performance
The Samsung Odyssey OLED G81SF delivers exceptional performance that justifies its premium positioning. With a pixel density of 166 PPI, it offers the sharpest image quality available in a gaming monitor today.
Color reproduction stands out immediately, with support for up to one billion colors and 99% DCI-P3 coverage. This translates to vibrant, accurate colors that make games like Assassin’s Creed: Shadows look breathtaking. The display also includes various color presets and fine-tuning options to suit different use cases.
The contrast ratio of 1,000,000:1 delivers deep blacks and bright highlights, while HDR10+ support enhances the visual experience with more defined lights and shadows. VESA DisplayHDR True Black 400 certification ensures that dark scenes maintain detail and depth.
The anti-reflection film effectively reduces glare even in bright environments, making the monitor usable in various lighting conditions without compromising image quality.
Where this monitor truly shines is in gaming performance. The 240Hz refresh rate combined with an ultra-low 0.03ms response time creates buttery-smooth gameplay that competitive gamers will appreciate. In fast-paced titles like Marvel Rivals and Call of Duty, every movement feels instantaneous and precise.
AMD FreeSync Premium Pro support eliminates screen tearing and stuttering, ensuring a fluid gaming experience across varying frame rates. The variable refresh rate technology works flawlessly, maintaining image integrity even during the most intense gaming sessions.
For content creators, the combination of color accuracy and 4K resolution makes this an excellent choice for video editing and graphic design work. The display renders fine details with remarkable clarity, and the color consistency across the panel ensures precise editing.
