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. About the author → How we check display specs →

Manufacturer description

It’s in good condition working order not much wear to it but the top buttons the membrane in the switches have degraded which is a common issue with these televisions so to someone that knows what they’re doing you would just need to de solder all switches except one and just use that one as your designated switch for your channels

SpecPicks scored Sony Trinitron KV-9400 Vintage 9" TV using a rating × review-volume × price-fit model applied to published specs and reviews across the displays & upscalers category. Sony's displays & upscalers lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.
