Mike Perry — Hardware researcher since 2014. For projectors, gaming displays and video upscalers, synthesises manufacturer specs against measured reviews (ProjectorCentral, RTINGS), treating non-ANSI "lumen" figures as marketing claims rather than first-hand lab testing. Core beat: GPU performance across gaming, rendering, and local-LLM inference. How we check display specs →
