Sharp 4T-B 70" Class 16:9 60Hz 4K UHD LED Commercial TV

The Sharp 4T-B70CJ1U is a 70 inch class Ultra HD commercial display that gives businesses, schools, and public venues a simple way to show crisp 4K content. It delivers a native resolution of 3840 by 2160 pixels at 60 Hz, so slide decks, menus, and promotional videos appear clear and detailed. Brightness tops out at 300 nits and the contrast ratio is 4000 to 1, which means images stay readable and colors stay vivid in standard indoor lighting.

Day-to-day operation is straightforward. Two HDMI inputs accept sources such as media players or laptops, while the USB port lets you plug in a flash drive for looped playback through the built-in media player. An ATSC/NTSC tuner with closed captioning is on board for over-the-air broadcasts. When you need centralized control, RS-232C and LAN terminals allow remote power, input, and volume commands from a control system.

The panel is rated for use up to 16 hours a day, seven days a week, making it a dependable choice for lobbies, retail aisles, conference rooms, and classrooms. Public mode, IR remote lockout, and the ability to disable the on-screen display help prevent unauthorized changes in unattended environments. Integrated 10 W stereo speakers add basic audio support, so most installations will not need external sound.
