This Is How Samsung's Glasses-Free 3D Monitors Actually Work
At GDC 2026 we saw a live demo of Samsung's glasses-free 3D gaming monitors in action and spoke with the Senior Director of Monitor Product Marketing to learn how they work.
One of the flat-out coolest demos from the first part of the week at GDC 2026 this year was undoubtedly the glasses-free 3D monitors that Samsung was showing off at a behind-closed-doors press briefing. Unlike older forms of 3D visuals that require specialized glasses, these monitors display fully 3D visuals for anyone sitting in front of them with no extra peripherals.
This is all thanks to the nifty little camera that's installed at the top of the monitor to track your eye movement.
"We're basically building upon the basic principle of binocular disparity. It basically says that when we're depicting images in the real world, our left and right eyes have two separate images. And then, we combine those two degrees for that perception.
To build upon that, we're taking that same principle and applying it to products and 3D monitors. You take a game, and it creates two separate stereoscopic images for the left and the right side, and then the camera on top of the monitor tracks your eyes in real-time, and then through our Samsung SDK, which is basically like the engine behind our Odyssey 3D, it maps that into 3D."

At the demo stations, Samsung had two separate experiences set up to try. One was a passive viewing experience, depicting a 3D trailer for Cronos: The New Dawn, while the second station was a fully-playable demo of Hell is Us, fully utilizing the monitor's 3D visuals.
Small details like falling leaves, dust particles in the air, or the drone following your character suddenly felt highly immersive. Since it's impossible to depict the sensation of the 3D effect in video or photo form, the impact is difficult to articulate until it's experienced.
"For 3D, it's taking the same image you'd see in 2D, but splitting it into two separate stereoscopic images...through a process called view-mapping, it basically compresses those images into one image that provides that 3D-like experience."

The main difference, it seems, between how these new Samsung 3D monitors work and how older 3D technologies like the 3DS worked is that Nintendo's handhelds used physical parallax barriers. Those were very limited from a hardware and technological perspective, but also just functionally in terms of "sweet spot" viewing angles.
Since the Samsung monitors use view mapping, this means they're not assigning individual pixels to each eye, but are instead rendering the entire scene in real-time stereoscopically for each eye and then compressing them into a single frame.
