Build ballroom AV around Lonton panels on mobile floor stands. For a 300-person ballroom, deploy two 98-inch 4K UHD panels flanking the stage and a 75-inch or 86-inch panel in each breakout room. The LG IPS panel at 3840×2160 delivers 350 cd/m² brightness visible from the back without dimming chandeliers. Anti-glare tempered glass (MOHS 7) handles ballroom lighting. 40-point IR touch supports live polling, whiteboarding, and Q&A annotation. Mobile stands mean 15-minute setup — roll in, plug in power, connect wirelessly. No rigging, no alignment, no wrinkled screens. Multi-language UI switches to German, Japanese, or Spanish in two taps. Android 13 runs presentation and conferencing apps; the OPS slot with Windows 11 handles event software. Wireless screen mirroring via Miracast, AirPlay, and Google Cast connects any presenter without dongles. USB-C 65W PD offers wired backup with charging. Built-in speakers fill breakout rooms; line-out feeds the house PA for the ballroom. WiFi 6 handles 200 attendees' devices without dropping.
