You're on a video call and fumbling for headphones because your monitor has no audio. Your colour work needs more than sRGB. And that fixed-height stand means you're craning your neck by 3pm.
The U27B3AF handles all three in one box. 27-inch IPS panel, 4K UHD at 3840×2160, HDR 10 support, and two 2 W built-in speakers so you can drop the earbuds for a quick Teams huddle. The height-adjustable stand gives you 110 mm of travel plus tilt, so your eyes sit at the top third of the screen where they belong.
Colour coverage is strong: NTSC 109%, sRGB 128%, DCI-P3 99%. Flicker-Free and Low Blue Mode are built in for long editing sessions. You get HDMI 2.0 × 2 and DisplayPort 1.4, with both an HDMI and DP cable in the box.
No USB hub. No fancy gaming extras. It's a clean, accurate 4K display with audio and a proper ergonomic stand.
Ships from our warehouse. Plug in, adjust height, done.
