Here at Murideo we talk a lot about video calibration, but what about audio calibration? The audio inside a home theater is one of the most important parts. So why are so many installers doing home theaters without properly setting up the room to benefit the audio?
We want to change that and are here to help, with the HAA kit from Murideo, and access to HAA training, you can become the a certified home acoustics expert. HAA classes will give you the knowlege you need to successfully set up a room with perfect acoustics. Find our more here. www.avpro.training/haa-audio1.html
The HAA Kit will provide you with all the tools you need to test the room and make sure you are setting up the best experience possible for your client. You can purchase the HAA Kit here. www.avprostore.com/HAA-Complete-Acoustic-Calibration-Kit-PLUS-p/au-haa-kit-plkus.htm

The Imaging Science Foundation has been leading the display calibration charge for over 20 years. In that time ISF has grown and adapted to each advancement in display technology that has come to market.
Today is no different, always pushing display technology forward, Joel Silver founder of ISF had this to say:
“The current HDR era is the very best of times for ISF Calibrators and their clients! The early HDR HDMI connectivity issues are now easily resolved by those with Level III skills, and the impressive HDR image quality now available through streaming, discs and HDR downloads is driving sales of ISF calibrations and large screen UHD TVs.
The upcoming year will bring us wonderful new content in HDR10, HDR10+, Dolby Vision's three offerings, HLG, SL-HDR1,2,3 and a glimpse of 8K and sporting events in 100/120 Hz. Today's innovations have revitalized movie viewing - tomorrow's advances in temporal resolution will revolutionize sports!
We will only offer five North American ISF Level III sessions in 2019 - overseas demand and private sessions will limit the number ISF sessions. We were touched by CEDIA's recognition of ISF's impact on thousands of businesses, and we look forward to seeing you at an ISF Level III event in 2019.”
Joel Silver was awarded the CEDIA Lifetime Achievement Award in September 2018 at the CEDIA Expo in San Diego. You are able to find his award video below.
Being an ISF certified calibrator you become an expert in delivering the best possible picture to the display, With the Level III Class, calibration has expanded from the display to the distribution channel. Attendees will get hands on experience with the latest calibration and video distribution equipment as well as work on a verity of modern projectors and displays. We hope to see you in 2019.
The Level III ISF event is a seminar that Joel himself hosts around the world. Planning for ISF Level III is being done now and we would love your help. Please vote for the city where you would like to see ISF in 2019 below.
In the above video, we take a quick look at calibration throughout the years, where it started to the present day.

We are honored to have Murideo's own Jeff Murray giving a presentation on 4K and HDR at this years Facilities Integrate Auckland 2018. As AVPro Global Holdings companies continue to expand in New Zealand and Australia we are excited as to support that region. Murideo and AVPro Edge fill a gap in the the market when it comes to testing and distributing 4K and HDR - technology that is expanding to all parts of the globe.
Here are the details about Jeff Murray's Presentation:
4K HDMI with HDR
Integrators now must understand how to successfully design and implement an HDMI solution that is capable of distributing 18Gbps of bandwidth.
Jeff’s two hour seminar has been tailored especially for the AV Integrator and will provide thorough insight into how to effectively design and implement a real-world distributed HDMI solution with 4K and HDR (High Dynamic Range).
What is discussed:
Who will be there:
The Murideo Fresco Six A/Six G combo has a robust HDMI cable test built in (to see a "how to" step by step guide click here).
This cable test was specifically designed for copper based HDMI cables. Testing fiber based or fiber/copper (AOC) hybrid HDMI cables is a little more tricky. Luckily we have a process that will help you test these types of HDMI cables.

Not surprisingly, friends, readers, potential clients ask me "What T.V. should I buy?"
The answer they are looking for is something like " a 50" Binford 3000".
My first response is "There is no good, short answer to that question". Then I ask, "What is your favorite screwdriver?" After quizzical looks subside -
What's that got to do with the price of tea in China?
No, really, what's your favorite screwdriver?
Well, it depends .........
Well, first of all, do I need a Phillips or a flat blade or a Torx
and then of course there is a size choice .... and I don't
always have the wallet to buy all Snap-On, so sometimes I opt
for an economy tool from the Bargain Bin Hardware store.
"See", I said ... "no short answer".
When I engage with a Home Theatre client, I would never begin to answer "What T.V." until I have made a site visit. There I learn about the ambient light environment, seating arrangements and get a sense of the budget. Only then can I decide what display to put in the proposal. I used to ask about viewing choices and usage patterns, but I've stopped that for some time now. I have learned that that all changes when you get a decent theatre system.
For every time I'm asked that question, I imagine my friend Joel Silver is asked it 100 times, so I decided to interview him on this topic.
So, Joel, what do you say when someone asks you "What T.V. should I buy"?
(J) -Terry, as you mentioned the room environment is absolutely a key factor in choosing not only a TV brand, but determines the very TV technology that is applicable to the task at hand.
We often deal with sizable rooms that have fantastic views from really large windows. That creates quite a challenge, and often the best solution is a large flat panel for daytime viewing, and a much larger retractable projection for night viewing - that is the ultimate Day/Night "viewing mode".
(T) - Joel, we have taught in class for years that REAL contrast ratio is the biggest care-about amongst non-technical viewers who still know what pleases them when watching on-screen images ..... but contrast ratios can be relative. Are there some absolute metrics that folks should consider?
(J) - For dealing with ambient light professionally there are fantastic Contrast Ratio performance standards from InfoComm. They specify multiple contrast goals for different viewing applications. We use their "Full Motion Video" standard all the time when planning a media room system with ambient light issues, and then we audit our own installations when we are finished to insure and document performance compliance on site.
For light controlled home theaters there is a new Video performance document from CEDIA and CTA that details both minimum acceptable and aspirational contrast ratios.
We don't have opinions on video performance, we simply learn and apply industry Standards……..
Two really fundamental considerations that we find to be completely client dependent are two simple specifications - "how big should the screen be", and "how high should the screen be mounted".
(T) - Yes, I often find myself urging clients to the next size up. Although ability to accommodate can be a real issue, more often than not, it isn't. I have never had a client say "You know, I wish we had gone one size smaller" - on the other hand, the opposite has been expressed from time to time.
Field-of-view is important to cause maximum envelopment in the movie watching experience. What was the commercial theater analogy I've heard you use to answer those two questions for students?
(J) -Those fundamental personal questions are best answered by simply asking our clients about their favorite seats in their favorite commercial movie theater. We have been doing this a long time, and have found that people are absolutely dogmatic about how far back they choose to sit from the screen. Once we know their preferences, we can recreate their personal choices for their own optimum viewing angles for height and width in their own homes.
We have even found instances where spouses have provided us with different seating preferences, and have uncovered long standing and quite stressful movie going situations. We have not found resolutions for these situations, but if you are diplomatic you may end up doing additional residences for both spouses.
(T) - Indeed. Job security!
(J) - Another major topic is light output. For flat panel TVs this is a quickly evolving scenario. HDR and wide color gamut have raised the bar for what we can wish for in our homes. We can now deliver image quality in many rooms that was just not possible a few years ago. So the right answer about what HDR TV to buy is now the newest and top of the line one!
(T) - So true. HDR and all that comes with it takes us into a whole new realm of movie enjoyment. Still, the best HDR is closely linked to light output of the display. What is your take on the fate of front projectors and HDR?
(J) - For projectors HDR remains a challenge, but if we deploy enough light output and native color space we can now deliver the best images ever seen in homes. Do not expect to easily equal a studio HDR monitor with a 1000 nit image with projection, but we can easily exceed all our prior expectations - and a very large projection screen HDR wide color gamut image in a light controlled room is fantastic.
The real answer to "what TV should I buy" is best answered by a good demo. The recent stellar progress in image quality simply cannot be described in print - and mainstream retail demos of uncalibrated TVs in poor lighting show a mere hint of what is now possible.
The best of the new HDR digital video images live in rarified air. The few Dolby Vision theaters worldwide provide a superior new movie going experience that even non technical people appreciate. The few custom installers that have mastered "The Art of the HDR Demo" are now updating all their client's old systems. This is a new era of image quality - and right now is the best time in memory to buy a new TV!
(T) - Thanks Joel for your time. I'm sure our readers will heed your counsel and spend their money more wisely as a result.
Once again Murideo was at ISE 2018 and we had a great time. We hope you enjoy some of the pictures for our products around the show, as well as our lovely staff. Thanks for everyone that stopped by our booths this year.
As an AV professional, buying a new TV for my own home is always a little more stressful than it should be. Since I deal with this stuff on a daily basis, I am hypersensitive when it comes to improvements, new features, and pricing. I am not the type to buy a new TV every model year, in fact just like everyone else I am looking for the best deal.
After passing on the 2016 6 series LG OLED, I decided that the 2017 C series was the one for me. They had finally fixed the dreadful CMS and it finally came out of black much better. These were 2 things that were terribly important to me as I am constantly on the quest for the “perfect” picture. I had a feeling that the chrome bezel would have bugged me, so in December of 2017 I decided on the 55C7.
As CES 2018 was approaching, the question in the back of my mind started to linger...did I screw up by not waiting for the 8 series? Did LG come up with something that is going to blow us all away? Well Now that CES 2018 is over, we know a little bit more about the 8 series OLED and what to expect in the upcoming model year.
LG showed off 2 models that received a lot of attention. One of them was something that some of us have been predicting for years...a TV that rolls up when not in use. This is something that I can see as a practical use. I’ve always been a sucker for automation, and I love the idea that I can hide my TV when it is not being used. I also love is that this isn’t simply a show off feature. Since the TV can roll up and down freely, you could have the screen exposed in such a way that all you see is a stock ticker, weather information, and much more (maybe the Bitcoin price for those who love to torture themselves). For the cinemaphiles out there, goodbye black bars! In a theater application things can get tricky and expensive when trying to hide black bars. In this case however, it is just a matter of unrolling the screen enough so that the display is in a 2.35:1 aspect ratio. For 16x9 content all one needs to do is unroll the screen all the way. I’d love to see an option to mount the unassuming white enclosure upside down on the wall or ceiling so the screen unrolls down similar to a traditional 2 piece system, but that may be wishful thinking!
Crazy display #2 would be the 88” 8k OLED. Unfortunately this is a prototype piece for CES so don’t rush out to Best Buy expecting to see it on display. The folks who saw it had nothing but great things to say about it, and if we have learned anything about prototypes at CES this may be a prediction on what we will actually see rolling off the assembly line within 5 years. Only time will tell!
So what about the rest of the OLED line? What will we see at the big box stores and on the front page of our favorite A/V websites in 2018? Luckily LG has some cool plans!
First let’s get one thing out of the way because I know you are wondering. The 2018 8 series will not feature HDMI 2.1. We are all excited about it, but it will be at least 1 more year for the LG OLED line. Not to worry though...there are still some great improvements within the line.
Luckily LG decided to not confuse everyone with a change in the structure of the model line. The entry level model will continue to be labeled a “B”, followed by “C”, then “E” (picture on glass), and finally the ultra flat wallpaper thin model keeps the “W” badge. All models will support HDR, Dolby Vision, HLG, and a format that we were surprised with in the 7 series called “Technicolor”.
Want to order an Uber from your TV? Now that is possible as all models in the 2018 LG OLED line will have the Google Assistant built in. Check out vacation photos, set timers, and more, all with the power of your voice. Still need more control? Each model will work with the Google Home, Google Home Mini, and the Amazon Echo.
LG has introduced a new processor to handle the heavy lifting. The “A9” processor claims better color, sharpness, contrast, and faster Smart TV operation. Each model will have the A9 processor with the exception of the entry level B8 model. The B8 will continue to use the A7 processor which was found in the 2017 7 series OLED TVs. More on this in a moment.
All models in the 2018 OLED line will feature HFR, or High Frame Rate. At 120fps, this is will help with blurry, quick motion without the use of motion interpolation. It is important to mention that 120fps HFR only applies to internal streaming apps and OTA, not outside sources. As previously mentioned, the entry level B8 model will use the A7 processor. Because of this technical limitation the B8 will not be able to simultaneously display HDR and HFR. This should be enough for hardcore gamers to ignore the B8 and jump straight into the C8.
Each model in the 2018 OLED line will feature Black Frame Insertion (BFI). When movies, TV shows, and video games are made, the images we see are not actually moving. When we see enough still images in a short amount of time our brains interpret these images as if they are moving. If the display doesn’t flash from one still image to the next quickly enough, we see this as motion blur. BFI helps this by inserting a full black frame in between each usable frame in the image. Some viewers are sensitive to this and describe the display as “flickering” while some do not notice it at all. Because there are now twice as many frames as before there is a bit of loss in light output, but BFI will help with motion blur without the use of motion interpolation. LG gives BFI a new name called “Motion Pro” and will be available in SDR and HDR modes.
The 2017 LG OLED TV’s featured “Active HDR”. This was a great feature as it added active metadata to HDR images, making them look more like real life. Turning the feature on was a bit confusing as LG called it “Dynamic Contrast” and it only worked correctly when set to LOW. Luckily in the 2018 models they have implemented the same feature, but now they call it “Dynamic Tone Mapping”, which makes a little more sense. Because the TV inserts its own metadata, these displays will most likely not be compatible with HDR10+.
The 2017 7 series LG OLED calibrated quite well, and the 2018 8 series looks like it will be even better with the introduction of built in Look Up Tables (LUTs). LUTs are important to calibrators as they give us much more than the typical calibration controls. Until now, a LUT could only be implemented by a rather expensive box that sits last in the signal chain before the TV, and had to be controlled by software such as CalMAN. The OLED models that contain the new A9 processor will be capable of 33x33x33 LUTs while the B8 model with the A7 processor will be capable of 17x17x17 LUTs. The display will talk directly to CalMAN, which makes things MUCH easier for calibrators as this will save a significant amount of time when calibrating the 20pt grayscale and Color Management System (CMS).
Each model will come in the following sizes:
-B8 55”, 65”
-C8 55”, 65”, 77”
-E8 55”, 65”
-W8 65”, 77”
Like the 2017 OLED line, no models will support 3D. All models will be in stores by June 2018.
Gamers and videophiles will be able to take advantage of some new features in the 2018 LG OLED line, but unless there is a significant price reduction 2017 model owners can rest knowing that they made a good decision by buying a 7 series. If you own the 2016 6 series OLED, the 2018 8 series will be a significant upgrade. Now it’s time to sit back and see what happens with pricing, which is usually the ultimate factor.
