Easy POS Docs - Customer-Facing Display
For tills with a second monitor plugged into the same register PC, Easy POS can drive a live, customer-facing screen that mirrors the current sale — items, running total, payment status, and a thank-you screen once the sale completes.
Enable it per POS Profile, then use the Customer Display button in the Cart header to open it (a named window, so re-clicking focuses the existing display instead of opening duplicates).
This targets a same-PC, dual-monitor setup — a separate tablet/device on its own network is not supported today.
