HDMI max length for Projector 1080p / 4K

[lucid]

Personally? Yes. A little.

I've seen good businesses go to the wall, and people's lives take a hell of a hit, because consumers value price above all. It breeds a crappy industry. HDMI cabling is a good example. The blind obsession with price leads consumers to buy bad products, and that demand means more crappy manufacturers tuning out junk. They in turn squeeze out the companies that make good reliable product. It's a downward spiral that does the consumer a disservice in the long run.

I think the problem is more so the confusion created by the lack of clear standards.

If I search on Amazon for a 15m hdmi 4K cable and a whole list of appear in the search, I believe that they should work regardless of the price. It’s not for the consumer to figure out if the advertising is false or not.

At the end of the day if a digital cable works it works. I don’t care if it’s braided or has gold coloured connectors etc (that many of these “expensive” cables feature). So obviously I’ll look for the cheapest variant I can find. The trouble is that nobody (cheap or expensive) make it easy to tell if the cable is compatible because the standards are so convoluted.

It sounds like you're just going to have to pay out for a Monoprice, they're not that dear in the whole context of the setup. If you spent £2000 on speakers you'd spend more than £12 on speaker cable wouldn't you, so a 2 grand projector with a £100 cable isn't a huge disparity.

from thread discussion the monoprice active/spectra7 don't seem to deliver either ... so its not clear there is any 15m solution

Apparently 'Monoprice 21567 SlimRun AV HDRCable for HDMI Enabled Devices 4K@60Hz, YUV4:4:4' is the one to go for, from this thread: https://www.avsforum.com/forum/168-...operly-reliably-support-18gbps-hdmi-2-0b.html

The issue isn't the standards. They're perfectly clear. Anyone can look them up. What the problem is is whether each cable MEETS the standard.

it is an optical solution though, which from earlier long distance hdmi threads we kind of knew would work - also with caveats, like, potentially needing a voltage inserter.(didn't inspect ruipro spec) ... a comment in the avsforums thread would suggest cables maxout at 6m.

At least the Amazon specs, would have suggested their/monoprice HOSS cable would have worked, so difficult to trust them with $150+importduty, maybe their web-site is more honest. ... following lucids comment
