Optoma Technology N3981K 98" UHD 4K Commercial Monitor

The Optoma N3981K is a commercial display built for teams that need a screen large enough to be seen from the back of a lecture hall yet sharp enough for detailed data and video. At 98 inches, it delivers native 4K UHD resolution, so text stays crisp and graphics look lifelike even when visitors stand close.

A brightness level of 500 nits and a matte finish help presentations stay clear under bright lights. Whether the monitor is mounted in portrait mode for digital signage or in landscape mode for meetings, the picture quality remains consistent across the entire panel.

Because the display runs on Android 11, you can install familiar apps, play local media files from the 32 GB of internal storage, or launch a browser without adding an external player. Built-in Wi-Fi and Bluetooth simplify wireless content sharing, and the Display Share app lets participants mirror a laptop, phone, or tablet with just a few taps.

Three HDMI inputs handle laptops, media boxes, and video-conferencing systems at the same time, while an HDMI output lets you daisy-chain a second screen. USB-C and legacy USB-A ports support flash drives, webcams, and touch accessories. Dual 10 W speakers cover most meeting rooms without extra audio gear.

The panel is rated for nonstop 24/7 operation, making it a reliable choice for control centers and retail floors that never power down. Facility managers can oversee multiple units through the Optoma Management Suite, pushing firmware updates or adjusting settings remotely from a single dashboard.

Mounting follows the common VESA 800 × 600 pattern, so installers can use standard heavy-duty brackets. An HDMI cable, remote control with batteries, and power cord come in the box, allowing you to power up and present right away.
