Apple iMac with Retina 5K Display Calibration Review – How Good is It?

Posted on:

The goal — see how well the new Apple iMac with Retina 5k Display conforms to system standards.  Apple has always had quality displays, but is it good enough for VFX artists, Photographers, and Editors to do their color critical work?  The quick and dirty — the display comes adjusted to an arbitrary target somewhere between the HDTV Standard of Rec.709 and the Computer Standard of sRGB.  Technically, a computer display should be optimized for sRGB, which is very similar to our HDTV Standard of Rec.709 with the differences being:

– Computers use full range video, in 8-Bit Space:  0-255

– HD Standards use Legal Range Video, in 8-Bit Space:  16-235

– The Gamma response curves, or how fast it goes from black to white, is an approximately 2.2 in sRGB and 2.4 in Rec.709.

The Apple iMac with Retina 5K Display is shipped very close to the sRGB/709 Color Space, but the gamma was closer to a Power Function of 2.3 instead of the sRGB 2.2 or the Rec.709 2.4.  This will result in computer content looking more contrasty and saturated than it should; however, as I state in the video review, the initial appearance of the display is extremely attractive.

To calibrate, we tried several different programs to create a custom ICC/Display Profile for the iMac.  There were a number of bugs in getting the display to dial in at the bottom end of the gamma curve, but it did come within the tolerance of the specification, just not as perfect as we’re accustomed to.  We’re working with various software vendors to attain a fix in a future update.

We also attempted to measure the full color capability, comparing it to the Adobe RGB standard, but the display is not capable of hitting that target; in fact, it didn’t even come close!

Most users will want to target sRGB, which the monitor will hit with proper calibration and we expect it to only get better as the various calibration tools improve to accommodate the latest OS X Yosemite updates and graphics cards utilized in the system

How often should I calibrate my display?

Posted on:

How often should I calibrate my display?  We’re asked this question nearly every day.  It’s also a question that’s not difficult to answer.  How often a display should be calibrated comes down to two things:  how often the display is being used; and, how much tolerance of error you’re willing to accept.  In this episode Dave will cover this topic from a multitude of angles including how various display technologies drift over time.

Whether you own a Plasma, LCD/LED, OLED display, or even a projector, you’ll have a better sense of how often you should calibrate your video system after listening to Dave’s answers.  He’ll provide some excellent guidelines so you’ll know what’s best for editors, colorists, or home enthusiasts.

Early Look at the Sony 4k OLED 30″ Reference Monitor

Posted on:

Avical had an opportunity for a deep dive technical conversation during a private demonstration of the upcoming Sony 30″ 4K OLED Broadcast Monitor currently slated to ship in February 2015.  Rather cool bits here so tune in to be ahead of the curve on this truly impressive display. Duration 11.5 minutes.

There is much more on the podcast but if you’re in a hurry:

  • The panel is the 4th Generation OLED Panel:  4096×2160 Native Resolution.  30” Panel.
  • They are targeting both on set and in post-production for their markets.
  • It is designed as a high performance monitor.
  • They targeted accuracy and stability instead of features, though it will have some features.
  • They are suggesting that calibration will be stable for up to one year.
  • Gammas:  2.2, 2.4, 2.6, Applying Rec.1886 as a Power Gamma 2.4.
  • Panel can handle HDR (high dynamic range) and is capable of 1000 Nits.
  •  Electronics have 12-Bit processing, but the panel is 10-Bit.

Update for this post: See the following article for more details and a special note that there is a 56″ version of this new OLED display. The article is dated April 2013 so we assume we’ll see both sizes coming soon given the 30″ was being demoed recently as discussed in the podcast.

CES 2014 Report!

Posted on:

The Consumer Electronics Show, or CES as it is often referred to, is one of the largest showcases for new technology of the year.  I’ve personally been fortunate to say that this is my 13th CES Show; however, I can also say that it is the most disappointing.  While there are many aspects to the show from cell phones to washer/dryers, we often focus on the home theater and video products hoping for there to be something compelling to look forward to in the spring— this year, it simply isn’t the case.

HDTV has been available for over a decade and Ultra HD has been the talk of the town for the past two years taking the spotlight as 3D quickly fades away.  Pulling up to the front of the convention center makes it hard to not notice the banners touting Ultra HD from manufacturers like Samsung and LG, but even with a lot spent on advertising, we find ourselves still wanting.

LG introduced probably the most complete line-up of displays including Ultra HD, Curved and Flat OLED, and Smart TVs utilizing the webOS platform.  The LCD/LED based displays are available in sizes from 49 to 105-inches and will be shipping this spring/summer with all displays including HDMI 2.0 and USB 3.

LG’s OLED lineup will come with curved screens  at 55, 65, and 77-inches with a 55-inch flat ‘Gallery’ model that is meant to imitate living art when not in use.  The OLED line-up will be WRGB based with a white, red, green, and blue sub-pixel system making up the image.

Sony didn’t show any OLED displays this year.  They seem to be distancing themselves from the technology on the consumer side, but still pushing forward on the broadcast side— the PVM, FVM, and BVM OLED is very popular in the Hollywood Post-Production industry.  Sony did demonstrate their LCD/LED display line with ‘X-tended Dynamic Range PRO technology’, a form of image enhancement that is said to increase the dynamic range of the display by up to three times normal.  Sizes in the new product line are 40, 48, 49, 50, 55, 60, 65, 70, 79, and 80-inches, Ultra HD displays are available starting at 49”.

Panasonic has discontinued their plasma development; as such, the focus on the floor was LCD/LED displays showcasing their “Life+ Screen” Smart TV technology.  The new technology allows the user to interact with the TV via facial recognition, voice recognition, a mobile application for your smartphone or tablet, or simply the remote control.  The platform leverages Panasonic’s cloud and sends data to learn what you like in order to make suggestions for content across its’ built in applications.

Samsung released quite a bit of news this year, but nothing that stood out.  The Samsung Smart Control and updated Smart TV remote are minor improvements to last year’s offering including gesture recognition.  The new Ultra HD TV line has improved integration with content providers to deliver Ultra HD content to the consumer through streaming services.  Of note, Samsung plans to offer Amazon, M-GO, Netflix, as well as content from Comcast and DirecTV in Ultra HD.

The Samsung TV line itself really took a step backwards this year as Samsung worked to blend their curved technology with their Ultra HD LCD/LED displays.  Color is said to be enhanced with Samsung’s new ‘PureColor™’ technology that allows for more color adjustment over last year.  The Ultra HD line comes in three series the S9, U9000, and U8550 and will range in size from 50 to 110-inches in both curved and flat versions.  All Ultra HD models will have HEVC, HDMI 2.0, MHL 3.0, and HDCP 2.2.  Additionally, Samsung is continuing their Evolution Kit with the UHD version for easy upgrading in the future.

Sizes for Samsung’s curved line-up are:  55, 65, 78, 105-inches.  The flat display line-up comes in 50, 55, 60, 65, 75, 85, and 110-inches.  An announcement regarding the state of Samsung’s plasma display line will come, “later in 2014.”

We didn’t expect much from Sharp at CES as we’ve always found their displays to be incapable of accurately reproducing color as per system standards; however, we figured we would give them a quick look.  In addition to having some Ultra HD displays, Sharp was demonstrating their Quattron + Revelation Technology which we are told, but don’t believe, divides the sub-pixels in half allowing for more sub-pixels.  What Sharp couldn’t explain is how that actually converts to real image detail since the pixel is what determines image detail and the sub-pixel is responsible for the color of that particular pixel.  As with everyone else at the show, Sharp will now ship with HDMI 2.0.

Toshiba revealed very little in the way of a full display product line, but instead showed off a number of concept pieces including a 5K Ultra HD display and a 65” curved LCD/LED display.  The display that will be shipping in 2014 is the Ultra HD Radiance LCD/LED display.

VIZIO was the most exciting display demonstration I had the privilege to attend at the show as it was an invite only at the Wynn Hotel, but it was nevertheless impressive.  While Vizio has always offered a great value proposition with their display line they’ve started to extend that in an attempt of dominating at all levels.  For 2014, they have their entry level E-Series display with options to buy with and without connectivity, local dimming, and full array backlighting in models over 24-inches.

The M-Series is LCD/LED with a Pure Pixel Tuning technology said to optimize brightness and contrast in additional to the local dimming circuitry for dynamic adjustment.  As a video purist, this is probably not something that we’ll be interested in, but it is nice to know that VIZIO is developing and customizing their video processing algorithms to stay competitive with the rest of the industry.  This series goes all the way up to 80”.

The P-Series from VIZIO is their Ultra HD display line.  It is LCD/LED based and comes in various sizes from 50 to 70-inches with full array backlighting.  VIZIO has worked to develop their own video processor that they call the ‘VM50 Picture Processing Engine’ and have integrated the HEVC codec for streaming Ultra HD, HDMI 2.0, HDCP 2.2 support, and even 802.11ac wireless networking.

While we were impressed that VIZIO was bringing a very promising videophile display with their customizations developed for the P-Series, we were even more impressed when they showed us the upcoming Reference Series.  The Reference Series is a partnership with Dolby that will enable VIZIO to deliver 10-bit content directly to the consumer for a significant improvement in picture quality.  Today’s consumer sources are 8-bit, even Blu-ray.  In our current 8-bit system the majority of video information is between levels 16-235 allowing for 219 shades of gray, but in a 10-bit system the majority of video information is between 64-940 increasing the shades of gray to 876!  Not only is 10-bit exciting, but VIZIO claims that their Reference Series is capable of meeting the Rec.2020 Ultra HD standard for color gamut.  We haven’t heard from any other manufacturer making this claim, if true, it would mean that VIZIO could have the first Ultra HD display capable of producing the full set of colors in the Rec.2020 standard.  Needless to say, we’re excited to get a chance to look at the new Reference Series for the display’s capability and the quality of content.

There were a few new comers including TCL and technology introduced illustrating Quantum Dots which is not quite ready for primetime, but certainly something to watch out for.  Overall, television technology for 2014 was evolutionary, not revolutionary.  Improvements have been made in many areas, but we’ve also taken a few steps back— curved displays have been receiving significant criticism as there was a huge push to making displays flatter and thinner and the curve display completely reverses those efforts.  If you’re looking to buy a display now, there are certainly some great options, but certainly nothing compelling enough to upgrade from a set one or two years old.

JVC DLA-RS6710U Quick Review!

Posted on:

Today we had the pleasure of working on the new JVC DLA-RS6710U projector and found it to be a significant upgrade from previous models.  Here’s a quick overview of our general findings.

The JVC DLA-RS6710U is JVC’s premiere D-ILA home theater projector for 2014 and reaffirms JVC’s commitment to perfecting the line.  Previous JVC projectors did not perform nearly as well as the new RS6710.  As an example, gamma tables did not measure as claimed in older model projectors and have been corrected in the 6710. Fortunately, the JVC projectors are some of the most configurable projectors on the market and allow for customized gamma tables to be created, and advanced grayscale adjustments to be performed.  Today, the JVC RS6710U improves upon the older design by adding the ability to upload your own tables to achieve the desired result.  In addition to gamma improvements, the grayscale tracking has also been significantly improved— the two-point grayscale adjustments render a near flat grayscale response throughout the entire range; of course, if you wanted to adjust the grayscale in more depth, you can.

The JVC’s internal color tables do not provide ideal results for achieving Rec.709.  The internal table is close, and the color management system, or CMS, will allow improvement over the internal table; however, the JVC’s internal color tables push 100% saturated colors outside the target range and the CMS system does not allow for all saturation levels to be properly represented.  Ultimately, there is either an error where 100% saturation is outside the target, or saturations less than 100% are under saturated in order to achieve accuracy at 100% saturation.  When calibrated to minimize the overall error, the results are within the tolerance of the standard.

Panasonic TC-P65ZT60 Review – Calibrated by Avical

Posted on:

Hi All,

We recently had the pleasure of working with the HomeTheaterReview.com team; assisting in their evaluation of the Panasonic TC-P65ZT60.  Avical optimized the “ISF Day” and “ISF Night” modes allowing for reviewer Jerry Del Colliano to experience this reference grade plasma display at its’ best.

The “ISF Day” mode was calibrated to Rec.709 with a gamma of 2.2 to accommodate the room environment when ambient light is present; whereas, the “ISF Night” mode was calibrated to match the Rec.709 and Rec.1886 specifications allowing for accurate colorimetry and gamma response.  We utilized the AV Foundry VideoForge with custom built test patterns, a Photo Research spectroradiometer, and CalMAN 5 video calibration software.
