The DS-D5A75RB/A3 expands the Eco G3 series to 75 inches for larger presentation spaces. Its IPS panel delivers 1200:1 static contrast with superior viewing angles, making content visible from wider seating arrangements. At 3840×2160 resolution and 400cd/m² brightness, it maintains crisp visuals across auditoriums and large conference rooms. The 50-point infrared touch and Android 14 system remain identical to the 65-inch model, ensuring feature parity.

- Gigabit Network Connectivity: Dual RJ45 LAN ports for teaming or failover — ensures stable content distribution in networked classroom scenarios
- Zero-Lamination Glass: Direct touch-to-LCD bonding reduces glare and improves optical clarity across the 75-inch surface
