I wouldn't want to guess at anything further than about 30-35'. The longer the cable, the more likely you are to have issues with the signal. I use DVI and HDMI to about 25' with no discernible problems. Buy a cable (make sure you can return it) and try it out if distance is a question.
Whats the safest max distance for HDMI cables? I have noticed on some sites 50-100 foot HDMI cables.. will these suffer and signal drop outs or any sort of issues due to their length.
I use a 50ft run of a single HDMI cable with no signal loss..
The HDMI specification does not define a maximum cable length. As with all cables, signal attenuation becomes too high at a certain length. Instead, HDMI specifies a minimum performance standard. Any cable meeting that specification is compliant. Different construction quality and materials will enable cables of different lengths. In addition, higher performance requirements must be met to support video formats with higher resolutions and/or frame rates than the standard HDTV formats.
The signal attenuation and intersymbol interference caused by the cables can be compensated by using Adaptive Equalization.
HDMI 1.3 defined two categories of cables: Category 1 (standard or HDTV) and Category 2 (high-speed or greater than HDTV) to reduce the confusion about which cables support which video formats. Using 28 AWG, a cable of about 5 meters (~16 feet) can be manufactured easily and inexpensively to Category 1 specifications. Higher-quality construction (24 AWG, tighter construction tolerances, etc.) can reach lengths of 12 to 15 meters. In addition, active cables (fiber optic or dual Cat-5 cables instead of standard copper) can be used to extend HDMI to 100 meters or more. Some companies also offer amplifiers, equalizers and repeaters that can string several standard (non-active) HDMI cables together.
I've got dual 50' HDMI monoprice cables from my plasma to my wiring closet.
I notice some sparklies at 1080i but since my plasma is only 720p I just run it in that resolution. I'm not sure if its the cables, eletrical interference or my HR20 that is causing the problems. The HR20 directv receiver is much better on HDMI than the old Directivo HR10-250 -- I used to get a ton of dropouts with that thing.
Now that is one of the dumbest things I have ever seen posted about HDMI...
OP, nobody can predict with certainty whether you will be successful at a particular distance. And other folks' success doesn't necessarily mean that you will be successful at the same distance. Performance depends on the characteristics of the equipment at both ends, the HDMI cable itself, anything else in the signal path, and the resolution, frame rate, and color depth you are running.
not trying to start a bunch of crap about cables. BUT i have noticed differances in cables. "cheap" ones from monoprice etc. are not good for long runs. if you notice the cables from better cables etc. use an inline "amp" and they work fine, at long distances. im personally using a 45ft. or close to that from better cables with no problems..... jmho
Depends on who makes it. Solder, shielding, conductor size all matter. The manner in which the wires are terminated to the end connector is also critical. When ordering long lengths, make sure there is a liberal guarantee involved.
Two 15' high speed HDMI cables in series does not equal a 30' high speed HDMI cables. Longest certified high speed passive HDMI cable is about 25'. That said a 30' cable of the same construction should work just fine for most folks because most of use aren't pushing the limits of HDMI bandwidth. If you do need a 30' high speed cable, you can get an active cable.

Yeah.. I run a 50' hdmi in my house. It works great for me. I bought it at monoprice.com.. Awesome cable place. The hdmi cable I got is super thick and high quality. About a half inch in thickness..
Absolutely, but remember just if you are running 1080p/24 then you are using about half the bandwidth that HDMI could run with. So, that same cable when pushed beyond 1080p/60 (such as UHD/4K) may not work anymore. With any HDMI cable, the higher the bandwidth, the shorter you can go with no bit errors.
That's why your 50' cable works. It's a really good Standard Speed cable that works beyond 720p/1080i but how far beyond we don't know. A High Speed cable is guaranteed to work for anything planned for HDMI (at least until HDMI 2 comes out some year) but of course is not available at 50' as a passive cable.
Yes I want it to be ready for hdmi2.0, I cannot wait too long. Apartment is under construction and the piping is still accessible at this point but wont be for long. It will make easier fishing as I can separate the piping and see where the cable is stuck if I have problems.
It seems that existing cables will be compatible with 2.0, so the issue is to maintain a good speed over such a long distance (75ft).
