You want HDR, but it's not displaying on your TV or Projector? Well this guide will walk you though troubleshooting this issue.
One of the most common issues that integrators have today is not being able to trigger HDR on a display. This can be frustrating, especially when it seems like all of the stars are aligned and everything in the system is HDR capable. Here are some tips on system setup and troubleshooting that will help you in case you run into this issue.
In the following scenario we are looking at this system:
UHD BR player---> AVPro Edge Matrix switch--->AVR--->Display
Some tips before you start troubleshooting:
1) Be sure that ALL devices in the system are 18Gbps capable and have the most up to date FW.
2) Be sure that all devices are configured correctly for 18Gbps. This includes ensuring that you are using the correct input and output on each device and checking the setup menus for things like "HDMI Deep Color", "UHD Color", or "HDMI Enhanced". Each manufacturer does things a little differently so be sure to check the owner’s manual for specifics.
3) TEST ALL HDMI CABLES BEFORE INSTALLATION. Just because the packaging says 18Gbps doesn't mean that the cable is functional. Most HDMI cables are mass produced, and it is not uncommon for "budget" HDMI cables do be DOA or have some type of issue. Also, a cable that passes 18Gbps at 2 meters may not pass 18Gbps at 5 meters even though the cables are from the same series or manufacturer. TEST TEST TEST!

4) If you are playing a disc, be sure that you put in the UHD disc and not the HD disc. Most UHD movies include both versions so it can be confusing.
5) If using Netflix, be sure that the associated account has been upgraded to Premium. This must be done from a web browser.
6) EDID management plays a big role in troubleshooting these types of issues. Be aware that every device with an input has an EDID. It is essential that you understand how EDID works and how to manage it within each device in the system. For more information on EDID click here
How to troubleshoot for "No HDR":
*NOTE - Conduct these troubleshooting tests with either the Murideo Fresco or the Fox & Hound kit. This guide is written for the Fresco kit, but the process is almost exactly the same with the Fox & Hound kit. Always have a known good 18Gbps HDMI cable in your kit. You will use this for testing different components in the system.
Testing the source
Testing the matrix switch:
If the source is outputting an HDR signal, the HDMI cable connecting the BR player to the matrix switch tests out, and the Matrix Switch’s EDID is correct, then the problem should be solved. If not, confirm that the HDMI cable that connects the matrix switch to the AVR is passing 18Gbps. If it is not, replace the cable. If the cable tests out and shows zero errors, it’s time to move on to the next component downstream. In this case that would be the AVR
Testing the AVR:
Since the AVR has an input and an output you will have to test both.
Testing the TV
At this point you have tested every other component and every HDMI cable in the system. If you are still not able to get HDR to the TV, follow these steps to test it:
In some cases, you may be dealing with an HDBaseT Matrix Switch. Here are some tips from HDBaseT that will endure a successful installation:
1) LAN is thy cable
HDBaseT runs on a regular LAN cable (Cat5e or above) so any best practices regarding Ethernet installations also apply here. Cable performance is defined by the quality of the cable, the distance of the connection, the handling of the cable, and the video resolution expected. A rule of thumb is that the higher resolution, the better the cable should be. The same goes for distance. The cabling infrastructure in any project is likely to be around for a long time – it should last longer than any other component in the network, and choice of cable should take into consideration new applications, additional users and potential expansions of the whole system.
WE CANNOT GUARANTEE PERFORMANCE UNLESS USING Cat6a OR HIGHER
2) Thou shalt not untwist your wires unnecessarily
There is a reason that the wires are twisted: it cancels out electromagnetic interference (EMI) from external sources and crosstalk from neighboring conductors. When terminating the cable, make sure not to untwist more than half-an-inch (and preferably a quarter-of-an-inch) from the point of termination, and remove as little of the sheath as possible.
3) Thou shalt handle your cable with care
LAN cables are fairly resilient. Yet, any rough handling, such as tight tie wraps, clamping or stapling can damage the cable, compromising performance or even preventing signal transmission. Tie cables loosely with appropriate cable wraps, and make sure to use appropriate cable support systems when too many cables are involved, such as trays, carriers or J-hooks. If pulling cables is necessary, make sure not to pull too hard because that also may cause pairs to untwist and degrade performance. Cable physical protection safeguards the integrity of data transmission.
4) Thou shalt not overbend your cables
Another important issue for cable integrity is the bend radius. Bend radius is the inside curve of the cable during and after installation. It is best to keep the minimum bend radius at least at four times the diameter of the cable – that means that the cable should not be bent below that radius, so as not to damage it and compromise signal transmission. Overbending may loosen or otherwise modify the wire twisting and increase susceptibility to external noise and near-end crosstalk within the cable.
5) Thou shalt keep your cables away from power sources
Cables should be kept at a distance of at least 12 inches from power cables. In an environment prone to high EMI, it is best to use shielded cables. Most Cat5e cables are unshielded, which makes them more flexible, durable and inexpensive. But they are also more susceptible to EMI.
If using unshielded cables, keep them away from any source of EMI such as other cables, transformers and light fixtures. In high RF environments, it is best to use shielded cables.
The same applies to shielded connectors. In a shielded connector, the signal pins are surrounded by a metal shield, and further reduce electromagnetic interference. Shielded connectors provide a better fit and therefore better performance.
6) Thou shalt mind your distances carefully
HDBaseT delivers the 5Play feature set over 100m/328 ft. One of the factors that affects distance is the quality of the cable used, the working environment, and the video resolution expected. Higher quality cable will keep the signal better than low quality cable over distances. A noise free environment will deliver better performance over the distance than a noisy or EMI-prone environment. Some HDBaseT equipment allows for Long Reach connectivity – 150m/492ft – for lower resolutions of 720p.
7) Thou shalt not use patch cords unnecessarily
If possible, avoid patch cords or cables altogether, as every connection introduces losses in the transmission. If absolutely necessary, make sure to use less than two per cable run and keep each less than five meters from the end.
8) Thou shalt terminate carefully
One of the advantages of HDBaseT’s using of LAN cables is that they are easily field terminated. That means there is no need to pre-measure cables and bring all the setup ready ahead of time, saving time & money. Make sure to use proper equipment for termination, such as cable strippers, electrician scissors, and crimpers. Also, make sure that both ends of the cable are wired according to the same scheme, either T568A or T568B. Never use both in the same installation. It is also recommended to check with HDBaseT manufacturers which scheme their products are optimized and equalized for, to take full advantage of the expected performance.
9) Thou shalt be thorough and test, test, test
Testing is crucial to guarantee both cable quality and signal integrity. Pre-testing can save hours and resources from troubleshooting any issue ahead of time. During and after installation, a professional test equipment will check connections and transmission of the installed infrastructure, beyond broken or mismatched wires, but also any hidden issues that may cause interference or loss of signal. Make sure to test every cable as it is installed and terminated, to identify individual problems as the installation goes.
10) Thou shalt be organized
Document and label all cabling components to facilitate any upgrades or expansions later, including diagrams. Remove any abandoned cables to prevent accidents or fire hazards. Avoid routing cables through pipes and holes, which may limit additional future cable runs.
There are many ways to troubleshoot a system, and with the proper tools and methodology you can track down problems in a minimal amount of time. Come up with a plan, take things one step at a time, keep track of what you have and haven’t tested, and if problems continue to persist you can always call our tech support department at 605.274.6055
For years televisions have been plug-and-play. From the introduction of color television, to component, to the early years of HDMI, everything just worked. Today, we live in a world of catching up. Our legacy set top boxes struggle to produce 4K while advanced 4K displays sometimes resist the change to new formats. But hope is not lost, understanding common issues in today’s mixed resolution world can decrease the amount of time spent troubleshooting.
4K and HDR have taken the world by storm. Next-Gen gaming consoles and premium streaming devices have made this possible within the home but not all displays are as accepting as others. You may find a host of problems while simply trying to connect your device.
Distributed systems are a perfect way to deliver all sources to any part of the home; but what about HDR sources on legacy displays that do not support it? While scaling to the resolution of the display may show picture, you might find an issue with the image displayed.
Dolby Vision is the cream of the crop in terms of HDR. The ability to adjust brightness levels frame by frame attracts many consumers to buy displays capable of doing it. Unfortunately, not everyone can agree on how to process Dolby Vision leaving us with different profiles used in the market. If the source plugs directly into the display, this is not an issue. However, in a distributed system with multiple displays capable of Dolby Vision, they might not be processing it the same.
As displays continue to move from 4K to 8K and beyond it is almost guaranteed that new issues will arise. Being able to diagnose these problems now will help your ability to address them in the future.

Here at AVPro and Murideo we talk a lot about ISF calibration and how important it is when building a high performance A/V system. Display calibration is necessary to achieve two goals:
As important as ISF calibration is to a home theater system, it is as equally important in a commercial environment. Let’s take your favorite sports bar for example. Next time you go, look around at all of the displays see if they all match. Check out the grass on the baseball field. Does it look real or radioactive? Take a look at the white jerseys. Can you see detail in the jersey or is the white totally blown out? Calibration will fix all of these problems by making all of the displays look the same.
Next time you encounter a video wall, maybe at an airport, take a look at each panel. Especially when an advertisement pops up. Are all of the panels equal in brightness, or are some brighter or darker than others? Do they match in color, or are some white while others are a blue-ish white? Now imagine that you are a marketing executive for a brand that pays for advertising space in that airport. What would you think if you saw your brand or logo on the screens and the color of your logo was incorrect? All of these problems will be fixed with calibration since all of the displays are calibrated to the same standard.
In many cases a commercial display will be initially set up in its brightest picture mode. Not only does this ruin the image quality, but it can literally be painful to look at. That last thing someone wants after a nice dinner in a restaurant is a migraine. In one extreme case, in an airport I had to close my eyes while coming down the escalator because the LED wall is entirely too bright. Not only is this unnecessary wear and tear on the display, but it can be dangerous!
As important as ISF calibration is in a home theater system, it is equally and arguably more important in a commercial environment. In these cases, the goal is not only image fidelity and accuracy, but also to save the life of the displays and to keep people looking at these displays comfortable and safe.

For years AV Technology has been plug and play, things just worked....
In today's world of HDMI distribution, things are different. Variables between displays and sources have continued to increase in complexity. Each product has their own detailed specifications that are slightly different than other, similar products. These specifications rely on something called EDID (Extended Display Identification Data). Contained within the EDID information is metadata sending preferred resolution, audio, timing, and a host of other information pertaining to the capabilities of the display.
When a source is connected to the display the EDID information is sent back to the source, which will then generate the correct signal. Most displays have a setting that must be enabled to do HDR formats, these settings can change the EDID information.
The largest problem in distributed systems is the mismatch of EDIDs from different models and manufacturers. AV manufacturers handle these issues in two different ways, unmanaged and managed. In the example below we compare two matrix switchers, a 4x2 with unmanaged EDIDs and a 4x2 with managed EDIDs.
Once you have an understanding of managing EDID, that knowledge can be used to tackle all kinds of problems both in the field and in design. From shortening sync times, fixing color space, or just getting the best quality audio and video, EDID management can change the whole system.
AVPro Edge has made a huge leap forward in EDID Management. Using the AC-DA12-AUHD-GEN2, AVPro has created an EDID Compiler mode which uses the video capabilities of a display or projector and combines it with the audio capabilities of an AVR or soundbar. The DA12 also includes a 1080p downscale port allowing support for a legacy AVR. This can bring Dolby Atmos to your home theater while avoiding AVR limitations and shortening sync times. AVPro Edge continues to push the edge of innovation.
When I started calibrating, TVs and projectors were nowhere near as advanced as they are today. A TV back would only have a few controls and they were usually buried in the minefield of the service menu. Sometimes the controls worked, and sometimes they didn’t. I just had to do my best with what I had to work with. I still run into these situations sometimes, but luckily it’s not often. The difference today is that our equipment and software are light years better and the calibrator community is as big and as strong as ever.
I want to invite you to join our newest hour long webinar on display calibration in 2019. I'm going to do a quick refresher for those calibrators that may be a little rusty, then I will talk about all the advancements in imaging science, we will also talk about all the mis-information that is out there as well as what the future holds.
One of the most popular videos on our YouTube page is my calibration webinar from last year. But this one will be the most exciting one I’ve done so far. I’ll have 3 special guests on to talk about some of their experiences and what they are looking forward to in 2020 and beyond.
Calibration Expert Guests
Want to learn even more?
If you haven’t taken the class before, there is not a better time than now. During the ISF class we spend 3 full days covering everything related to electronic imaging and the standards that hold everything together. This includes hands on activities such as fiber termination, front panel TV controls, and manual and automated calibration of the grayscale and color gamut on the displays that we have in class. EDID management and HDCP compliance cause headaches everyday. We will show you how to use the necessary tools to keep track of and manage these things. Not only will you come out of class with a solid foundation of video signals and a new skill, but also CEDIA and AVIXA credits. If you take and pass the ISF exam you will be listed on the ISF site as a certified dealer so potential customers can easily find you.
We see a wide range of students come through the ISF class. Seats have been filled by not only A/V integrators, but also cinematographers, post production editors and colorists, broadcast engineers, medical professionals, even home theater enthusiasts looking to learn. Continuing education in our industry is a MUST, and we invite you to class even if you have taken the course before.
With the introduction of 4K and HDR (High Dynamic Range), the AV industry has been flooded with various signal types that may not be supported by your distributed system.
Does your device say 4K60Hz, yet still no signal?
Is you device “full 4K”?
The truth is, some devices cannot handle higher bandwidth 4K (4K60Hz 4:4:4 8Bit/18G or 4K60Hz 4:2:2 12Bit/18G). Using a 4:2:0 Chroma manufacturers can produce “4K60Hz” devices that are only handling 50% of the color information, as well as not displaying full HDR (4K60Hz 4:2:0 8 or 10Bit/(9G). Leaving customers with a choice to use only a few select 4K formats. For years manufacturers have been hiding behind this vague specification affecting switches, extenders, and even HDMI cables. Looking for specs that include 18Gbps or 4K60 4:4:4 with HDR, help notate a wide open, high bandwidth 4K signal. AVPro Edge provides many 18Gbps solutions, including all of our 444 extenders and AUHD products, that ensure the best video quality for your customers. Murideo, trusted in HDMI testing and troubleshooting, also provides tools to help confirm correct signaling with the Fox & Hound Testing and Troubleshooting Kit and the SIX-A Analyzer & SIX-G Generator Test Suite.
The Imaging Science Foundation continued its international training, this time making a stop in Australia. ISF teamed up with AVPro and AVD to put on a display calibration course down under. Jason Dustal ISF Level III Instructor, taught this class and he had this to say:
"ISF along with our partners at AV Distributors recently hosted the first Australian ISF class in a couple of years! The class was attended by a wide variety of people including experienced calibrators, medical professionals, post production professionals, and some who are brand new to calibration! We spent time talking about 18Gbps distribution and how to troubleshoot HDMI issues. Lots of hands on activities with both flat panels and projectors gave the attendees a glimpse of what to expect in the real world when servicing clients! We'd love to see you at the next class, cheers mate!"
ISF hosts classes all year long around the world, if you are interested in becoming an ISF certified calibrator register for class today.

In order for a distributed video system to work nicely with different kinds of displays EDID managing is crucial. What is an EDID?
An EDID is the data that is sent from a display to a source, this data tells that source what kind of signal to output. Some displays may ask for 1080p resolution with 2ch audio, and some may ask for 4K resolution with HDR colors and Dolby Atmos, in order for these two displays to play nicely inside one installation we need to manage the EDID to work with both. Every integrator has been here; you connect everything in a new installation, play your source and....... one or more displays do not have picture. If you are working with 4K, you may have an EDID problem. The Fox & Hound has many capabilities, in this article we are going to explore how you can use your Fox & Hound to manage the EDID's in your system. There are two main ways you use the Fox & Hound for EDID management:
Testing an Multizone Video Distribution System
Scenario: 8 video zone installation, using different brand displays, the source is a Apple 4K streamer. When the integrator turns on the system, 4 displays have a picture, 4 displays say no picture. You have tested all the cables and connection points and extenders and they all work - You have an EDID problem.
The Answer: Find the television inside the system that is the oldest or has the lowest capabilities. Your goal is to find an EDID that will work with all the displays in your system. Connect the Analyzer to this display and copy the EDID. You will be able to see all the information from that EDID including:
The final step would be to place this EDID from your Analyzer into your video matrix switcher. Connect the analyzer to the input of your matrix switcher and using the matrix web GUI you can use this EDID on each input. We recommend AVPro Edge's line of matrix switchers for easy EDID management.
Saving your favorite EDID's
Scenario: You find a EDID from a specific display that works great for all the products you like to install, even when you use different brands of displays, this EDID works every time. You go to a new install and they don't have the type of TV that outputs the EDID you like to use. How can you get your favorite EDID into this installation?
The Answer: By using the Fox & Hound HDMI Testing and Troubleshooting kit you can save your favorite EDID for later use. This might not seem that exciting but if you are working with 4K and HDR, having the perfect EDID is essential. To give you a head start the Fox & Hound comes loaded with the most useful EDID's already loaded.
This is only one of hundreds of ways you can use the Fox & Hound to save time when working with HDMI. If you do not currently have a Fox & Hound from Murideo right now is the time to buy, we just introduced a payment plan where you can get a Fox & Hound for $199.00 a month for 12 months.
