At 30' you can still stick to passive HDMI cables, but consider looking for 8K cables only because they are built to a higher standard with less loss and someday soon you may already need an 8k cable. :)
HDMI from TV for longish run to stereo system
I use my stereo system primarily to listen to music. But in my music room I have a new smart TV that I occasionally watch. I want to use my speakers rather than those that came with the TV (which goes it’s data by Wi-Fi) I have to run an HDMI cable about 30 feet from the TV to my components to do so. I’m told that I need to get active HDMI 2.1 cables for this. I was shocked by how expensive some of these are. I would appreciate recommendations for cables for this purpose. What specs for the cables would be relevant?
