Samsung Odyssey Ark 2nd Gen (LS55CG970NNXGO) (55-Inch Curved 4K Mini-LED VA/165Hz/1ms/95% DCI-P3/HDR2000/Rotating Stand) Review
The Odyssey Ark 2nd Gen is Samsung's massive 55-inch curved gaming monitor, featuring a motorized rotating stand that pivots the entire 16:9 display into a 9:16 "Cockpit Mode" and multi-view functionality for splitting the screen across multiple sources.
The Mini-LED VA panel with a 1000R curve delivers approximately 95% DCI-P3 color coverage and Quantum HDR2000 certification, one of the highest HDR peak-brightness tiers available on a gaming monitor. 165Hz at native 4K with a 1ms GtG response time offers strong performance for a screen this large, though a capable graphics card is essential to sustain high frame rates across the massive 55-inch canvas. Against Samsung's own Odyssey Neo G9 57-inch also in this catalog, the Odyssey Ark commits to a traditional 16:9 aspect ratio at a slightly smaller 55 inches rather than the Neo G9's dramatic 32:9 super-ultrawide format, and adds the unique rotating "Cockpit Mode" stand.
