75" Collaboration Display for Teams

The LG CreateBoard 75TR3DQ-B is a 75-inch touchscreen desktop computer designed for interactive group work in classrooms and meeting rooms. An ARM Cortex A73 and A53 processor with 8 GB of memory runs the onboard whiteboard and sharing software directly on the panel.

Built-in Whiteboard and Cloud Tools

The display includes teaching templates such as a ruler, table and sticky notes that encourage active participation during lessons. Users can save, import and export files directly to Google Drive or OneDrive, and distribute meeting materials by email or QR code without an external PC.

Fixed Panel Specifications

The Direct LED panel has a 3840 x 2160 resolution, 400 nit brightness and a 5000:1 contrast ratio that define the viewing experience in bright rooms. Touch interaction is limited to the integrated screen surface, and the system-on-chip architecture means internal compute performance cannot be upgraded later.

Questions about this item

Will the ARM Cortex A73 and A53 processor need a firmware update to stay compatible with Google Drive or OneDrive sync?

The board runs on an ARM Cortex A73 and A53 chipset with 8 GB of memory; LG delivers OS and app updates over the network, so Drive and OneDrive integration stays current without hardware changes.

What limits continuous all-day annotation at 3840 x 2160 resolution?

The 8 GB unified memory shared between the Cortex A73 and A53 cores is the first bottleneck during sustained white-boarding, large PDF imports or multi-window lessons at 2160p.

How loud and hot does the 75" Direct LED panel get after eight hours at 400 nit brightness?

The fanless Direct LED design produces no audible noise; surface temperature rises slightly above ambient but stays within normal operating range for a 5000:1 contrast panel at 400 nits.
