Review on 🔌 Sewell Echo V2 HDMI to HDMI Video Scaler: Choose from 1080p, 720p, or 4K@30Hz Output Resolutions by Andrew Burnside

I understand it's just a generic device that gets renamed everywhere, but how do people use it for their computers? It works great with my console outputs, but why is it just crap and not knowing what to do when I send a 4k signal to it from my computer? HDCP? I suspect there is a problem here. But when I plug it in and all I get is a "No Signal" icon every few seconds, I just get pissed. No, this is not the end of the entire product. This is mainly for those who have a trusted signal source like a cable box or console, for that it should work perfectly.
