If you plan on staying sane ditch the Wireless HD and run a cable - HDMI over HDBT on a single CAT6 is the most reliable option.

Choose an HDBT Extender which supports IR and PoH (power over HDBT).

I would agree with Joe. Use CAT6 500Mhz cable, stranded is OK if under 100 feet total. Use factory terminated cable if possible. Don't use RJ45 wall jacks as they will introduce signal reflections at each connection point. Also, no sharp bends in the cable, 90 degree bends should be around 3 inch radius. Single piece of cable is the most reliable by far. Four devices is tough to pull off: source, extender 1, extender 2, and display.
edit: is this outside display temporary or permanent? the latter requires more work due to potential ground bounce.

Thanks for the reply Joe. I agree wired is the way to go for best / most reliable connection. Unfortunately, I don't have a fixed position for the TV and I already have the wireless and it's tested out good so far. So I think I'll try it. I'm also going to try a non-powered HDMI extender to see if that will impact the solution (probably not - but it's returnable). If that doesn't work, I'll put coax through the wall and put a set-top box outside (under covered porch). That will remove the requirement to use an HDMI extender. I'll post an update on my progress.

Thanks for the reply Ward. See previous reply to Joe. I also appreciate the info on cabling. The outside display is temporary. I have multiple places where a TV would be nice sometime, but it won't be used frequently - so simple setup and takedown is ok. I generally have power available in those spots - so no long power cords expected.

Help with connections please

Looking at purchasing a duel zone AV Receiver: Pioneer VSX 1130-K, which will be stored in a media closet > 50ft away from the 2 sources (TV's) I want to hook it up to. I will have 5 HDMI inputs feeding into the Pioneer. My questions are

1. How can I make the connection and keep the 4k content in both zones?

2. Will I be able to access all my HDMI inputs in both zones if I go to an HDBaseT Extender Kit or other? If I am hooking up the two HDMI cables from the Receiver and not the actual Sources themselves (Roku, Apple TV, Blu Ray, Other).


Any recommendations would be greatly appreciated.

Thank you !

I tried reading through this thread, but I not sure I was able to find the answer I was looking for.

I have a single Cat6e cable run of approx 30' . What specifically do I need to add to each end to use this Cat6e cable as an HDMI cable for things like gaming boxes (eg. Xbox One or PS4)?

Thanks

I have a media room with Cat5e pre-wired by the builder. Attic access above the room is very limited so unable to run a new HDMI cable drop. I am trying to setup 3D projector connecting to my Onkyo receiver.

What's the best quality HDMI over single Cat5e balun out in the market that would work perfectly for my needs?

Another product to add to the list

- Source-end: Harman Kardon AVR354 (upconverting content from 720p to 1080p, as well as 1080p native content)
- CatX Adapter: Vanco 280713 (Bought from mcm audio, <90$. Available on Amazon)
- CatX Cables: 88' Dual Cat6 UTP Solid (self terminated, tested with dsp-4300, pass with 12db+ of headroom on cat6 standard)
- Far-end: Sony Bravia KDL-46S5100
- Resolution(s) tested: 1080P 'Full Pixel'
- Status: Seems to work well for the most part. Can start systems in any order, and sync occurs without issues. Switching inputs on the TV causes some sync issue with receiver (green screen instead of display), but may be related to AVR. Switching AVR Inputs fixes problem. Did not test with audio.

Hey all, appealing to your knowledge for help please. I have a Pioneer receiver that is displaying just fine to my Vizio TV via the HDMI Extenders (Monoprice model # 6532) with a 75 ft run of dual Cat 6 cables. The input port on the TV is port #5 which is 4K @ 60hz possible. The sources have been my xbox One and xfinity x1 connecting via HDMI to the receiver. The receiver is a SC-65 which is an elite and can handle 1.4a and does 4K "pass through".

I built a HTPC with a gigabyte mobo w/z170 chipset board. I am running onboard graphics (HD530). The HTPC is fully functional via DVI and a small LCD monitor, and can display directly via HDMI to a 720p LG that is not the main TV. When I connect it to the receiver and run it to the Vizio, I get a "no signal" graphic on the TV. Keep in mind, my A/V closet is 75 ft from the theater and directly connecting the HTCP to the TV is not really an option.

After reading through multiple manuals, I think its a combination of the receiver and the extenders. The receiver cannot down compress a signal from certain sources (video compression) - in this case the HTPC. The extenders are rated for 1.2.

Is it logical to think that the xifinity and xbox both are not outputting at 1.4? Ive tried multiple hdmi's on the receiver and the TV. I'm concerned that I will buy the new HDbaseT extenders and that they will not make a difference. Is a dedicated video card the answer or will I still be stuck with a legacy receiver restricting the data via "pass through". Do I need both the new HDbaseT extenders and a vid card? I've found others online with this same chipset not having an issue with 4K @ 27hz. Is it the TV? I guess Im grasping at straws.

Lastly, did you see the most recent Walking Dead? How bout that!!! 'Appreciate your help and feedback.

Working on the solution - the mobo will connect directly to the TV thru HDMI port 5. When it is connected it does say 2160 as the resolution. I could not get it to work with any other port.

If the z170 chipset is having some sort of handshake issue, then that could be why the extenders failed as well as the non-4K hdmi ports, since they are 1.2 only.

I have two different 4K hdmi extenders on order now. Once is a Gefen 4K HDMI 2.0, HDCP 2.2, 4K @ 60hz which, from everything I can tell, is the latest and greatest chip from the HDBaseT consortium. The other is an E-SDS 4K, HDMI 1.4 with "cinematic 4K" from Amazon. Both use a single Cat5e/6 cable. Hopefully this will resolve any of the issues I'm dealing with from the Z170 chipset. The E-SDS is not HDMI 2.0 or HDCP 2.2, and I do plan on installing a dedicated gaming vid card for HDMI 2.0 in the future.

I have been using the following HDMI extender for a while. At first everything seemed fine, but now it resync's every 40 minutes or so. (it isn't the source as I have tested multiple sources:
https://www.amazon.co.uk/Extender-Ex...twork+extender

So I am looking to get a more reliable setup, ideally one that can handle 4k at 60hz as well, to keep myself protected in the future. (At the moment I only send 1080@60)

I have 2 cat 6 cables running through the wall already (but they aren't both identical in length if that's required)

Any help is appreciated.

Existing kit - anything else changed in the 'environment', fridge, lighting etc which could be inundating your CAT cables?

Future proofing - currently it is problematic as no Extender can currently cover everything UHD BD can throw at a compatible Display, you can get close but have to compromise somewhere or go to Fibre.

Nothing I am aware of unfortunately, I will probably test my 2nd cat 6 cable to see if that has the same issues.

If I picked up an adapter that used 2xcat 6 would that then be more stable? Or is 2xcat 6 just the old standard that has been outdated now?

Ok, for now ill hold off on trying to get 4k 60hz. Ill settle for rock solid 1080p

Anything I should look for in extender kits? any terminology, or brands names I should try to get?

I find it really hard to determine what is worth it and what isnt, there seem to be no good reviews out there for these things. i.e.:
https://www.amazon.co.uk/Ex-Pro%C2%A...13XD7C6SNA683C

looks on paper to be brilliant, but I cant see any mention of refresh rate so I assume it does 1080@60 and 4k@30 but I don't like assuming on something that is going to cost me £90.

Just some feedback in case it helps anyone else.

Swapping to my spare cat 6 cable did nothing. So I ordered the Neet HDBaseT adapter. I am using it over ~10meters 1080@60. No issues at all so far, so it appears it was my old adaptor causing the cut outs.

I've been using a SIIG: http://www.frys.com/product/5827463?...BXcaAu9A8P8HAQ

For five years, and while it still works... it has never been a solid setup. I use it with a home theatre PC running Nvidia GTX graphics with HDMI out going into a Marantz Reciever, then to an Epson projector. While it would never run at 60hz, I dropped it down to 30hz using Cat 6 cable, and it worked... but then my receiver went out recently and I replaced it with an old sony pre HDMI inputs. I went to the store and got a HDMI audio extractor, ran HDMI to my projector, and a separate audio signal over optical out to the receiver. When I did this, the SIIG would not work on 30 hz. I went up to 60, picture very fuzzy with horizontal lines but worked for a short while, then i dropped down the 30hz with perfect picture, but the picture kept dropping/flashing slowly. So, then I go back up th 60hz which no longer works for some reason then back down to 50hz which is holding with a fuzzy picture. None of the numbers on the adjustable signal dial on the SIIG produce a decent picture.

After reading all 16 pages, I was considering buying the mono priced 6532... because im broke and cheap. What do you guys think, or would you recommend a differnet one? I dont have much finances to contribute to this anymore. That 40 dollars looks fantastic, but I hope its not spent in vain.

What I want to acheive is 1080p, 60hz, no dropped picture, no fuzz.... Im running 35 feet cat 6 cable.

Thanks in advance.

Good luck and let us know what happens.
HI, I would be great full if you could point me in the right direction regarding the below issue i have with my HDMI extender.

I have a CAT6 to HDMI extender to be able to view tv in my bedroom, however once i turn my main TV in the lounge on standby and then continue to view TV in the bedroom the TV signal discounts and the screen switches off. this is fixed only if i keep my main TV in the lounge switched on.

Dose anyone have a solution for this?

Thanks in advance
John

What is the source feeding the HDMI extender? Is it a matrix switch or an HDMI out from the existing TV? Is it an AVR?

Does you TV in the bedroom work if you turn it on with the other TV OFF to start?

A full description of you signal chain is needed for anyone to be of much assistance.

One thing not related to the signal chain is some companies (Panasonic in particular) have a feature where you can can control other TVs and devices from one master set.. I forget what it is called but when active it can drive you nuts with other devices going on and off.

Looking for better solution

Tried 2 setups, going to try 3rd.
This is low-end: 720p.

Application is a church sanctuary. 2 projectors 2 screens plus booth monitor. Option to add rear confidence monitor one day.
Run lengths:
150' to projector 1.
75' to projector 2.
Source is someone's laptop.
Currently testing with a 2010 Dell Inspiron 14R (N4010) with VGA & HDMI outputs.
And a 2011 HP EliteBook 8760w with VGA & DisplayPort outputs.
But really want guest to come in with whatever laptop and plug in and have it work.
I was testing using "Extend these display" on Windows 7 so I can have different content on the projector screen than laptop screen.
I can also set the resolution of the external display independently of the laptop screen display doing it this way.
Both projectors are Sony VPL-FX52 with VGA & DVI-D inputs--but no HDMI input.
Both 150' and 75' cables are Cat6 stranded, 24AWG cable (Cable Matters).

TRY 1 - VGA

Laptops VGA output into:
StarTech.com ST1212T 2 Port VGA over Cat5 Video Extender - Transmitter
which has 2x Ethernet outputs, and 1x VGA output for local monitor.
into the Cat6 cables
into 2x identical StarTech.com ST121R VGA Video Extender Remote Receiver over Cat 5
which have 2x VGA outputs each. I only used one of them each.

I was very happy with the signal distribution in this setup. I tested only 720p.
My problem was my projector is XGA and insisted on 4x3 aspect ratio. So when I sent 720p, it
stretched it tall. So I had to set the laptops to 1024x768 resolution for the external monitor and then constrain my image to 16x9.
Eg, 16x9 powerpoint presentation, or 16x9 video files from PC. These displayed properly on the projector.
4x3 video files, however, would display above and below my 16x9 screen.
So I returned those StarTech extender units to Amazon.

TRY 2 - HDMI

I was not happy with this solution.
I bought:
Tripp Lite 4-Port HDMI over Cat5 / Cat6 Extender Splitter, Transmitter for Video and Audio, 1920x1200 1080p at 60Hz(B126-004)
for the transmitter/splitter and
2 of Tripp Lite HDMI Over Cat5 / Cat6 Extender, Extended Range Receiver for Video and Audio 1920x1200 1080p at 60Hz(B126-1A0)
as the receivers.
Then I had to buy 2 HDMI-DVI-D cables
(AmazonBasics HDMI to DVI Adapter Cable - 3 Feet (Latest Standard))
(Amazon id=B014I8UL8U- - just joined, can't post links)
at the receiver end, to connect the HDMI output of the Cat5 receiver to the DVI-D input of the projector.
I also periodically swapped in a VIZIO 24" D24 TV with HDMI input at the remote end for testing.

The Dell laptop could never send a signal through the Tripp Lite splitter/exender that the Sony projectors would recognize.
Blank screen, no matter what resoultion I chose in Windows 7's Display Resolution settings (1080p 60Hz & 59Hz 32bit color, 1080i 25Hz 32bit color, 1080p 60Hz 16bit color, 1080i 29Hz & 25Hz 16 bit color, 720 60Hz & 59Hz & 50Hz 32bit & 16 bit color, 1024x768 60 & 59Hz 32 & 16bit color)

Swapping in the VIZIO TV as the second remote display, worked pretty well.
All the 16x9 resolution settings worked perfectly.
The 4x3 1024x768 was stretched wide on the VIZIO with no way to correct on the VIZIO.
Meanwhile, simultaneously, the projector was always blank just like when it was alone.

However, connecting Dell straight to projector using the same HDMI-DVI-D cable worked much better.
I was not given the 1080x option by Windows 7. Highest resolution offered was 1280x1024 which is a weird 1.25x aspect ratio.
In the 1280x720 range I was only offered 60Hz 32 & 16bit color.
These all worked I got my 16x9 aspect ratio on the projector.
In addition, when viewing a 4x3 video it did not spill over top and bottom, rather left and right got black bands.
For 1024x768 resolution, the projector was in proper 4x3 mode. 4x3 movie used up the whole screen, and 16x9 powerpoint and movie had black bands on top and bottom and so displayed correctly.

With the HP EliteBook DisplayPort output, I got it to display, but the projector was in permanent 4x3 mode.
1920x1080p 50Hz & 59Hz & 60hz 32bit & 16bit color : right side of screen was cropped off as if the image was internally 16x9 but only the left side was displayed to make displayed illumnicated image 4x3. About 10% of the bottom was cropped off too. Don't know what that's about. And when displaying a 4x3 video, the video was 1st centered in a virtual 16x9 with black bands left and right, then the right and bottom of this now-16x9 image was cropped to display 4x3. So 4x3 image, 4x3 display, but still the image was shifted and cropped.
1920x1080p 59Hz (but not 60Hz nor 50Hz) 32bit (not 16bit) : the picture was jumping up and down just a little bit. Maybe 6 times a second.
1920x1080i 30Hz & 29Hz & 25Hz 32bit & 16bit color : projector was in 4x3 mode and super-stretched. Like stretched 3x. About 70% of the image was cropped off the right, leaving only about 30% of the image (left side) displayed.. Mostly the left-right stretched out, but also about 1.2x stretch top to bottom (cutting off bottom 20%).
720 60Hz & 59Hz & 50Hz 32bit & 16bit color : projector in 4x3 mode, even more cropped than 1080 on bottom and right. About 80% of the right side of the image was cropped off, leaving only 20% of the left.
When at 59Hz picture was jumping up and down at about 6Hz to the eye.
1024x768 60Hz 32bit and 16bit color : projector in 4x3 but not cropped. my 16x9 content displayed properly with black above and below. And showed 4x3 content full screen no cropping. However, picture jumped up and down at a steady 2.6Hz rate.

Adding the VIZIO TV as the 2nd remote display.
1920x1080p 60Hz 59Hz 50Hz 32bit & 16bit color : the VIZIO had constant dropouts.
1920x1080i 30Hz 29Hz 25Hz 32bit & 16bit color : VIZIO perfect even while projector simultaneously borked as described above.
1280x720 60Hz 59Hz 50Hz 32bit 16bit color : VIZIO is perfect
1024x768 60Hz : VIZIO worked as expected.

Hoooking the HP EliteBook DisplayPort directly thru DisplayPort-HDMI adapter, then HDMI-DVI-D cable adapter to the Sony projector produced these results:
I was not offered any 1080x by Windows 7.
Highest resolution again was that weird 1280x1024 aspect ratio 1.25. which I didnt try.
1280x720 60Hz 32bit & 16bit color - perfect on the projector.
1024x768 60Hz 32bit & 16bit color - perfect, meaning 16x9 content displayed with black bands top and bottom, and 4x3 content displayed full screen.

So clearly, things are working direct PC-Projector, but with the Tripp Lite extender in the chain, it's not working.
In fairness, the Tripp Lite extender works very well with the VISIO TV.

I called Tripp Lite tech support. When he heard about the HDMI-DVI cables he stopped debugging and, only a little reluctantly, said I should return the devices.
In truth, it seemed he was looking for an excuse to blame the problem on, rather than fixing it.

So, I am looking for a new setup. I'm considering this:

A-Neuvideo 1x4 HDMI Splitter and Extender over Cat5e/6 System B&H # ANANI0104POE MFR # ANI-0104POE
bhphotovideo product id 1301237
Includes 4x remotes. Sadly, I only need 2.
$399
Anyone have any experience with this unit?

Well, I can tell you four things after 20 years of extender circuit design & mfg; 10 using HDMI:
1) God does not like any extender products in his house. Doesn't matter if it was built in 1716 or 2016. There is a much higher failure rate in houses of worship than even heavy industrial.
2) Stranded CAT cable over 100 feet is usually problematic for digital video due to higher capacitance.
3) Earth grounding is EXTREMELY important. Two prong power cords don't offer a reliable ground point and rely on connected equipment to provide this (ie: PC, display, etc). When you're using differential signaling to transmit from A to B all devices must have a solid reference for zero/ground.
4) Outside CAT cable runs will fail, usually sooner than later.
--My only other advice is order from companies that have a good return policy. As you've noticed you may have to test out more than a few different models.
-Regards

so what do I do

2) Stranded CAT cable over 100 feet is usually problematic for digital video due to higher capacitance.
3) Earth grounding is EXTREMELY important. Two prong power cords don't offer a reliable ground point and rely on connected equipment to provide this (ie: PC, display, etc). When you're using differential signaling to transmit from A to B all devices must have a solid reference for zero/ground.
4) Outside CAT cable runs will fail, usually sooner than later.--My only other advice is order from companies that have a good return policy. As you've noticed you may have to test out more than a few different models.

Thanks for the response?

1) So if Cat5/Cat6 Ethernet extenders, won't work, what then? HDMI repeaters?

2) Yeah, I worried about that. I've been testing using the 75 feet cable to eliminate that complication. I used the 150 feet on the VIZIO in my post above, and it worked fine. I will consider returning my 150 foot stranded and getting a solid.

3) These Tripp Lites only have 2-prong, no ground. I'll see that the next one does.

By the way, some of these use Power over Ethernet to power the remote receiver. Would that have a ground problem? Certainly power will have shifted at the end of the Ethernet cable, converted to HDMI/DVI and going into a wall-grounded projector. Sounds troublesome.

4) for me, it's all inside. Whew.

As for me responding to my own post. About my suggestion "A-Neuvideo 1x4 HDMI Splitter and Extender over Cat5e/6 System B&H # ANANI0104POE MFR # ANI-0104POE"

couple things: They only claim 164 feet. My run is like 125 feed and I currently have a 150 foot cable. Not sure I want to be that close to max spec.

Only 8bit color per channel. That's 24bit? My laptops seems to want to do 32bit color. What is that? 10.6667 bits per channel? How will your generic laptop respond to this ANeuvideo asking for 24 bits?

This one does do the PoE and so do I need to be worried about ground? Receivers do not have local power.

Also, I have been thinking that getting a splitter-to-cat5/cat6 in one unit is ideal.

But now I'm thinking maybe getting a good HDMI splitter with HDMI outputs, and a good HDMI-cat5/6-HDMI single channel solution might be better. Even tho it's two components.

Have a look at our HD DSX and Pro DSX 'HD over LAN' solutions - these are ideal for your type of installation and can be easily added to over time as you require additional Source or Display devices.

The HD over LAN solutions are far more robust/stable than cascading splitters and extenders.

Thanks Joe for the reply. I've asked Octava for a quote.

Continuing my thought of separating the splitter and the Cat5/Cat6 extender, I found these on B&H Photo Video. They're popular and have good reviews.

KanexPro 1x4 HDMI Splitter B&H #KASPHD1X44K • MFR #SP-HD1X44K
$67.26

and into 2 of :

KanexPro HDMI Extender over CAT5e/6 (165') B&H #KAHDEXT50M • MFR #HDEXT50M
2 at $79.80 each
Total: $159.60

Or maybe these are better (but much more expensive):

KanexPro HDBaseT HDMI Extender B&H #KAEXTHD100HT • MFR #EXT-HD100MHBT
2 at $256.99 each
Total: $513.98

Kanex seems to have a good rep in these forums from my search.

Might still need a VGA->HDMI or DisplayPort->HDMI adapter before the splitter (for some laptops), and a HDMI->DVI-D after the extender receiver into the projector. That complicates things.

Unfortunately none of the above boxes are grounded. I could wrap a wire around the box and stick it into the ground pin of an outlet, to ground it myself, if I had to. A little hokey, tho.

OMG! dont do that! suitable ground points can come from connected equip too. if the source has a ground plug - that is almost always connected to chassis ground (Dell, I'm lookin at you!). Perhaps the display has a 3 prong plug, that will suffice. If needed, you can use a grounding wire with two ring connectors. One attaches to the extender's case, the other end you can attach to the center retaining screw on the cover of a duplex outlet.
