Client was told a new cable or extenders are needed. Idea is non 4k sources on non 4k cable, switched through pre. 4k source on new HDMI cable, pull audio out of source for pre.
Straight T&M to retro cable and R&R projector. Dude asked if the initial labor quote to R&R projector covered this and the cost of a new HDMI cable or extenders. LOL....NO.
I am a trained professional..... Do not attempt this stunt at home.
