Selection notes

• Manufacturer figures apply to the exact model and cited document only. Confirm the supplied regional hardware, firmware and intended system.
• ISD supplies products only. Stock, price, lead time, package contents and local warranty require separate confirmation; an enquiry is not an order or reservation.
• A listed connector does not establish USB media, touch, Ethernet or network-control functionality.
• 4K signal handling is not native 4K panel resolution or a guarantee for every source and multi-screen layout.
• Panel and package dimensions are different. The specification-table panel size is not an installed wall, bracket or cable-clearance envelope; confirm the complete mounting arrangement.
• All listed brackets are optional, not included by default. Confirm the exact display, mounting load, complete bracket assembly and site requirements.
• Share the full model, quantity, signal source, screen layout and mounting requirement. Similar 55-inch models differ in panel depth, net/gross weight and package dimensions.
• The manufacturer packing list does not confirm the actual ISD-supplied package. Confirm package contents and local warranty with ISD; installation is not included.
