Welcome to the HDMI Extension Discussion Thread!
This thread exists to serve several devious purposes:
- document which combinations of equipment work great/okay/poorly
- civilly discuss the nature and technology of HDMI extenders
Public Service Reminders
Keep in mind also that these are all generalities and the internet phrase "YMMV" (your mileage may vary) applies greatly to this entire thread!In my personal experience with all that this thread has had to offer, the most important lessons learned are as follows:
- Most all extenders will work at 1080i60 and many also at 1080p24 without issue. If anyone is planning on running only 1080p24, 1080i, 720i/p, or less, then they shouldn't stress and instead just go try any of the LESS expensive extenders first.
- 1080p60 is a much different beast with double (or more) the data rate for full 1080p60 than other formats (1080i, 1080p24, 720p, etc). Doubling the data rate for full 1080p60 is a pretty daunting task and is where most extenders differentiate themselves or flat out fall apart.
- All the wireless extenders that I have researched (as of mid 2011) add compression. Whether or not the compression will bother the viewer, of course, can only be decided by the viewer. My recommendation is to always buy-and-try (whether wired or wireless), but make sure you have a good return policy, covering even if you simply and SUBJECTIVELY do not like it. Many retailers will only exchange and only in the case of a faulty unit. Others charge obscene "restocking" fees. Still others make you pay for shipping both ways and only refund the pre-shipping purchase price. Don't expect a full refund plus shipping charges both ways- few offer such generous policies. But be aware of what you WILL be charged should you not like your choice or it not work out as you hoped.
Which is better- HDMI or Component Video?
Let's be clear here with a few things:
- As far as physics go, triple run RG6 for Component Video (5x run if you also want L/R stereo sound with each wire on its own RCA connector) *beats the pants off HDMI*
- RG6 / RG6QS can carry a much higher bandwidth signal, much farther, with much less loss (or skew). It's not RG6 that's the problem, it's the industry and the content producers. In short, it's content protection that is the problem.
- Content producers lobbied hard (and quite successfully) for TV equipment makers to restrict component video inputs and outputs to 1080i60, and in many cases, even less than 1080i. So even if you WANT to run component video- often you can't. At least, not a full 1080p signal.
- HDMI does work well- when it works. But it was never designed to span long distances, or chain through a dozen different devices. It supports 1080p60 and higher, with embedded audio, CEC, audio-return, Ethernet, and said content protection, all in ONE multi-conductor cable. For what it is, it's a remarkable creation! But for what it is, it's also wrought with problems from implementation differences (interoperability problems between devices from different manufacturers) to signal glitches over longer runs, to strange, unexpected random problems when a cable starts going bad. It's technology at it's peak- remarkable when working properly; a nightmare when it's not.
So that leaves the unassuming user at a crossroads. 1080i over component video is rock solid all the time and even at absurdly long lengths-- but it's only 1080i. HDMI cables are markedly more feature-rich and much more convenient, with limitations in connector rigidity (bend/tug/weight stress on HDMI connectors generally decreases reliability life) and overall length.
HDMI extenders are trying to bridge the gap. From all we've seen in this unscientific thread, solution "A" will work absolute wonders for some users and be abysmal for other users. solution "B" will be the opposite. It does not look yet like any one single solution is a true "problem solver for everyone."
New HDbaseT solutions are beginning to hit the market. It will be interesting to see how they fare.
Please read this paragraph before posting
No matter what you do -- please contribute to this thread! What worked well, what worked poorly, and everything else in between. If you don't know whether or not your cable is Cat5, 5e, 6, 6, shielded, termination style, etc-- don't worry. Give us the information you have and we'll go from there.The bottom of this first post documents the combinations reporting to this thread as of the last-edited-date. Whether you are just beginning to search for an HDMI extender, or if you're ready to throw your Wii remote at your Plasma because nothing is working, check out the list below to see if there is a combination already tried that may be similar to your setup.

Original Thread Post

I'm ASSUMING that this is related to power glitches, but I wanted to see if anyone had any experience with this and could give me some other things to look into...
When the air conditioner kicks on OR off, video on my panasonic tc-p50g10 blanks out for a moment, then recovers. When A/C kicks on, the blank lasts a little longer and has to renegotiate HDMI.. When the A/C shuts off, the video blinks but doesn't have the delays associated with renegotiation.
I am assuming that this is causing powerline glitches, and that it's not some sort of EMI issue. I was EXTREMELY careful when building this new family room though-- it has its own dedicated 30A circuit with nothing else on it besides my A/V equipment (no lights, dimmers, fans, etc)... I also took care to run the power and A/V cables away from each other, and also isolated from OTHER circuits around the house. This circuit goes up and across the ceiling rather than "around the room" through the studs like all the other outlets.
I don't seem to recall it happening before I got my DVDO Edge video processor, but then again I wasn't running HDMI exclusively before the Edge. HDMI was only for bluray before the Edge was put in place.. I have since added a high def Tivo that has HDMI out, so that is another option to try (in case the Edge might be more/overly sensitive to power glitches than everything else in the system). To be clear though, it was already happening before the new Tivo came along, so I know it's not the Tivo.
I am borrowing two UPS's from the office tonight and am going to plug in all A/V equipment to them (TV in one, A/V rack in the other) and see if it still happens. But aside from that-- are there any other things I should look for? Are there any small yet useful tools that can be had inexpensively to measure such "glitches" on the A/V power circuit?
thanks!!

First Thread Update

(extracted from thread reply #84)
Well I'm pleased to say that I have been testing out a single-CatX extender (as opposed on the dual-CatX extender that a I have been using) for the past week or so and my problems seem to have vanished. Still using the same Cat5e self-terminated cable (just one instead of two). I don't want to be too premature, but so far I have yet to see any glitching occur--- even when I flip the ceiling fan switch like a mad-man (fast, repeatedly, one-shot, super-slow to hear the arc'ing inside the switch, etc).
I don't know how these single-CatX adapters work (yet, tee hee hee), but if this unit is any indication of the single- vs dual-catX technology, then I'd recommend folks start looking into the single-CatX solutions. Until I saw beemer533's post above about a single-CatX extender for $95, I wasn't sure of any single-CatX extenders out there that hit the same price-point as the (lower-cost) dual-CatX extenders. I would very much be interested in trying out the $95 PI single-CatX extender but at this point I have a solution and I'd just as soon leave it well-enough-alone!

I am now using one of these:
XTENDEX® ST-C5HDMI-150
It is truly "plug and play." --- But to be fair, the Arkview extender was truly "plug and play" as well, but just had this debilitating vulnerability to AC motor on/off cycling --- This unit however (so far!) does not seem to have the same vulnerability, and I also like that I can plug in the AC wall adapter for the pair at the source end rather than forced to plug in power at the destination end (the Arkview extender). All that's now plugged into the power strip at the far end now is the TV, and I'd rather keep it that way...
Good luck to EVERYONE else experiencing this problem. With as many views as this thread has received to-date, it is clear there is a problem out there that is not yet well enough understood to fix it once-and-for-all.
cheers,
