Digital Signage Upscale Guide: 4K Threshold vs 8ms Latency Decision

4K upscaling is viable only if source is 720p+ and p99 latency stays under 8ms at the endpoint's actual refresh rate, consuming 48% of a 60Hz frame. Independent technical note mirroring the canonical version: https://aivideoupscale.com/blog/digital-signage-upscale-guide-4k-threshold-vs-8ms-latency-decision.php

Abstract

4K upscaling is viable only if source is 720p+ and p99 latency stays under 8ms at the endpoint's actual refresh rate, consuming 48% of a 60Hz frame. Independent technical note mirroring the canonical version: https://aivideoupscale.com/blog/digital-signage-upscale-guide-4k-threshold-vs-8ms-latency-decision.php
