LG PK640S Series PK640S 86"
The integrated webOS platform with RS-232 control and a direct-lit panel simplifies content management for commercial deployments. Its slim design and embedded group management software make it a practical, networked signage solution rather than a consumer television. This display is best for corporate or hospitality environments needing a reliable 86-inch 4K digital signage canvas, not for home theater or gaming.
