75 inch 4K touch display for a medium conference room. The extra size over the 65 makes a difference in rooms where people are sitting further from the screen. Touch response is accurate and the Android 14 platform handles all our collaboration software.

We installed the 3753RK in our main boardroom. The 75 inch 4K panel is impressive for presentations and the touch functionality is used constantly in collaborative sessions. The build quality is good and setup was quick.

Xena G. · ✓ Verified buyer · November 2025

Good mid-size interactive display for a conference room. The 4K resolution is sharp at this panel size and the touch response is smooth enough for annotation and whiteboarding. Three months of daily use and the panel quality has not changed.
