Brilliance in a Compact Beast
The Samsung Odyssey G81SF 27" (2025) is a stunning addition to Samsung's high-end gaming monitor lineup. With its vibrant OLED panel, lightning-fast 240Hz refresh rate, and ultra-low response times, it delivers an exceptional visual and gameplay experience packed into a sleek 27-inch form factor. One of the standout features is its 4K resolution (3840x2160), which, combined with OLED's infinite contrast and true blacks, makes every detail pop - whether you're exploring immersive single-player worlds or playing competitive FPS titles. Motion clarity is excellent, and input lag is virtually nonexistent, making it a top-tier choice for esports and fast-paced gaming. The build quality is solid and premium, with the futuristic Odyssey styling and RGB CoreSync lighting that matches the ambiance of your games. It supports G-SYNC and FreeSync Premium Pro, ensuring smooth gameplay with no screen tearing. However, like other OLEDs, it requires some caution against burn-in, especially if you're using it for productivity or leave static elements on-screen for extended periods. It also lacks DisplayPort 2.1, which may matter for future-proofing, but HDMI 2.1 still offers great support for current-gen GPUs and consoles

This thing is actually bananas
The guy leaving a review for this at 2 stars is an absolute clown for not doing three seconds of research byb not looking at the specs directly below the listing. If you're spending the money you are on a monitor like this, you almost undoubtedly already have headphones ready to go, or will not soon after. The picture quality is phenomenal as advertised, framerate is stable, and the settings are descriptive and easy to navigate. The fact that is comes with such a crisp, clear, lagless PiP mode as well is insane! I was able to semi-afk BTD6 while playing mario kart on the mini screen in the top corner of the monitor :D The fact that it all works without needing additional software is a huge convenience too (looking at you, Razer >~>) I'm absolutely in love with it, I just need to build a PC that's capable of using this thing to its maximum potential!
