75-Inch 4K Interactive Display

The GTEK 75B1TWAR8128i7 is a 75-inch 4K interactive digital signage panel built for classrooms, offices and meeting rooms that need touch collaboration on a large screen. It runs a dual-OS configuration with Android 13 on an 8 GB RAM plus 128 GB storage module and Windows on an Intel Core i7-13620H with 16 GB RAM and 256 GB storage. Infrared touch supports up to 40 simultaneous points with palm rejection for natural writing.

Dual OPS Slots and Connectivity

Two OPS slots let you switch between Android and Windows without rebooting or swapping hardware, freeing the single HDMI, DisplayPort and D-Sub inputs for external laptops or cameras. Four USB 3.0 ports and two USB 2.0 ports handle peripherals such as document cameras or storage drives, while built-in 16 W stereo speakers cover audio for medium-sized rooms. The panel accepts 100–240 VAC power and draws a maximum of 460 W.

Upgrade From Single-OS Whiteboards

This unit replaces standalone interactive whiteboards that lock you into one operating system or require a separate PC for Windows apps. The jump is worth it when you need native Android 13 with Google EDLA certification plus full Windows 11 on the same 3840 × 2160 60 Hz panel, 178° viewing angles and 8 ms response time. It is not suited for buyers who need more than one HDMI or DisplayPort input, or who require a screen larger than 75 inches.

Questions about this item

Does the 460 W maximum power draw cause the screen to dim or throttle during long sessions?

The panel is rated for a maximum power draw of 460 W with a standby draw of 0.5 W, so sustained operation stays within the specified envelope.

How much heat or fan noise does the built-in Windows i7-13620H module produce when the board runs all day?

The Windows slot uses an Intel i7-13620H processor with 16 GB RAM and 256 GB storage; the unit draws up to 460 W at peak and 0.5 W in standby.

Which external devices must I already own to use the 40-point infrared touch and dual-OS switching?

The display provides 40-point infrared touch out of the box; dual OPS slots let you switch between the pre-installed Android 13 module and the Windows i7 module without extra hardware.
