Both models share the same 60Hz (variable with Adaptive-Sync) refresh rate and 3840 x 2160 4K UHD native resolution. Matte anti-glare screen surfaces are also used, which should be fairly light (i.e. not overly grainy). The 28 (U28) model uses the same panel as Samsungs previous 28 UHD offering, the InnoLux M280DGJ-L30 which is a TN (Twisted Nematic) panel. This offers 170°/160° horizontal/vertical viewing angles and has a 370 cd/m² typical maximum brightness. The 23.6 (U24) model uses a Samsung PLS (Plane to Line Switching) panel with 178°/178° viewing angles and a typical maximum luminance of 300 cd/m².
