I'm confused on what i need to get the pj running snow free. Do i need a 22 gauge hdmi? whats an active cable? conv. to cat 6, or to fibre? What is my cheapest best bet. why did my original 36 dollar cable work fine? until it went. Thanks for all your help and advice!!!!. cheers.
Check the archives, you'll find a bunch of recommendations.
Basically any HDMI cable has a chance of working for 1080p. It's just the cables labeled "high speed" are certified to do that bandwidth and beyond. So, you got lucky with your original cable *and* (most importantly) 1080p doesn't use the full high speed bandwidth. Enable "deep color" on both your source device and your projector and you'll likely get an even worse experience.
Now the problem with the cable length has to do with how "in-tune" the HDMI chipset is with the cable length. I'm sorry but I can't think of a better term right now than "in tune" - having to do with equalization, amplitude, noise rejection and many of those factors that change based on cable length and sending/receiving chipsets. So one chipset might work with a particular cable and another won't. This is why 25' is the maximum certified length for high speed cables since those are guaranteed to work with all chipsets. Try a true high speed cable and your problems will go away.
For 50 feet, you can roll the dice and see if another higher gauge standard speed cable will allow the bandwidth you are actually using to work. Or, check the internet for a cat 6 converter or an active HDMI cable - actually just check this forum's archives (use the "search this forum" option) for many choices.
