Review on 🔌 J-Tech Digital HDMI 2.0 Repeater Connector Extender Signal Booster with 1080P, 4Kx2K@60HZ Support, HDCP2.2/1.4, EDID Passthrough, CEC, HDR, and 18Gbps Bandwidth by David Mcdonald

This is for a downgrade, not an upgrade. I use this with the Revain FireTV 4K, Sony STR-DH550 and ViewSonic PX747-4K. The Sony receiver lacked HDCP capabilities to work with my shiny new 4K projector. I've been successfully tricked into believing it uses HDCP 2.2 and the projector doesn't care. Netflix test videos show 4K at 60 fps, Prime Video shows Ultra HD and HDR, that's all I care about. In the five weeks that I've been using it almost daily I've only had to restart it once, and I think it was more the result of other devices confusing the projector causing it to drop to 1080 than an issue with the Box. If this changes I will update the review.
