Framed inside thin bezels, the 23.8" VA panel delivers realistic visuals with 99% coverage of the sRGB color gamut. HDR10 support with a 3000:1 static contrast ratio and 250 nits brightness enhances videos, games, and photos with bright highlights and deep shadows. The 100 Hz refresh rate and 5 ms response time reduces motion blur while you're quickly scrolling, streaming, and switching between tasks. Connect a compatible laptop to transfer video and up to 15W over a single cable. An HDMI port is also available. Reader Mode lowers blue light levels for a more comfortable viewing experience when reading documents, browsing the web, or working for extended periods. Brighten up dark scenes and spot enemies faster with Black Stabilizer, which enhances visibility in shadowy areas. The Switch app transforms your screen into a multitasking hub for work, gaming, and streaming. Use the software to split the screen into up to six sections, customize display layouts, or launch video calls with a single hotkey. Navigate smart features with ease and switch seamlessly between your PC and the built-in webOS streaming platform, all with intuitive shortcuts. Free up your desk with the ultra-slim stand, which is designed to minimize clutter and maximize usable space.
