+description: "New side-by-side comparison pages for popular digital signage products."
+---
+
+You can now compare popular digital signage products head to head. Each comparison puts two products in the same category next to each other, with their pricing, supported platforms, headquarters, and capabilities laid out in one table.
+
+To open one, look for the "Compare with" section on a product's page and pick another product.
