DisplayPort 1.4 vs HDMI 2.1

A closer look at both DisplayPort 1.4 spec, and the newly ratified HDMI 2.1 spec to see the difference between them Both HDMI and DisplayPort can send high-definition digital video and audio from a source device to a display. Each format has had various updates and versions over time, but with the introduction of HDMI 2.1, it’s a good time to provide an update on the current standards involved in both.   We will be taking a closer look at both DisplayPort 1.4 spec, and the newly ratified HDMI 2.1 spec to see the difference between them. The HDMI (High Definition Multimedia Interface) specification was conceived over 10 years ago by a consortium of More…

What is Pixel Pitch and Why Does It Matter?

What is pixel pitch? Pixel pitch describes the density of the pixels (LED clusters) on an LED display and correlates with resolution. Sometimes referred to as pitch or dot pitch, the pixel pitch is the distance in millimeters from the center of a pixel to the center of the adjacent pixel. Since pixel pitch indicates the amount of space between two pixels, a smaller pixel pitch means there is less empty space between pixels. This equates to higher pixel density and improved screen resolution. Key Takeaways: Pixel pitch refers to the density of pixels A smaller pixel pitch indicates higher pixel density and higher resolution Pixel pitch is More…

What do integrators need to know about 4k content playback?

The amount of 4K video content available to be viewed remains relatively low. Netflix and Amazon Prime are currently the two best streaming sources, though the recent release of UHD Blu-ray opens the door for many more titles to become available in 4K. TV broadcasts in 4K are scheduled to start later this year. In the non-consumer world, PC applications dominate as content providers for 4K displays, as video graphics cards have supported 4k output for quite some time. 4K content requires substantially higher data rates than 1080p content. As a result, the existing H.264 / AVC compression algorithm traditionally used on various 1080p content simply More…

What do integrators need to know about wide color gamut displays and content?

Distinguishing WCG from non-WCG The color gamut of a display is usually quantified in terms of the NTSC standard created in 1953. Most LCD displays on the market today are designed to meet the HDTV color gamut standard, known as Rec. 709 (or alternatively BT.709). Compared to the NTSC standard, the Rec. 709 color gamut covers roughly 72% of the NTSC color gamut. In display circles, we refer to the color gamut of a display using this percentage NTSC measurement, such as “72% NTSC,” which is the most common specification for LCD displays on the market. While there’s no formal definition for wide color gamut (WCG), anything above 72% NTSC is generally More…

What do integrators need to know about color subsampling?

In order to reduce the bandwidth necessary to transmit 4K content, the new HDMI 2.0 specification includes support for 4:2:0 subsampling. This reduces the color information in the signal by 75%, leading to a 50% reduction in bandwidth. Much of the video content currently available is already 4:2:0 subsampled, so there won’t be any additional degradation of the image as a result of the subsampling. However, in other content, such as PC graphics inputs, 4:2:0 subsampling can introduce significant image artifacts. This is especially noticeable in text. When selecting a product with 4K @ 60Hz support, integrators should be checking what color subsampling More…

8K Connectivity

Demand for high resolution across all displays is on the rise, explaining why industry attention today has moved beyond HD to 4K and Ultra HD displays with sights set on the 8K ecosystem ahead. So why not just add 4 times the pixels of Ultra HD call it a day? Unfortunately, the high data rate required for connectivity makes 8K resolution more complicated than simply adding pixels. Consider an 8K image may: display up to 120 frames per second (fps) require a minimum of 10 bit color require the color sub-sampling 4:4:4, 4:2:2, or 4:2:0 One common example of this is an RGB signal with 8K pixels, 10 bits of color, 4:2:0 color sub-sampling, and More…

What do integrators need to know about HDCP 2.2?

Adding to the alphabet soup that is display specifications, HDCP stands for “High-bandwidth Digital Content Protection.” It was first developed by the Intel Corporation and is now ubiquitous across consumer video sources and displays as a way to protect copyrighted materials from privacy. According to the license holders at Digital Connection, HDCP “eliminates the possibility of intercepting digital data midstream between the source and the display” (like directing it to a recording device). It was first introduced for DVI in 2000 and has since gone through several iterations over the years. Each to support a broader range of devices and to overcome More…

Finding the Line Together

I watched a comedian recently who made a horribly inappropriate joke (I won’t even attempt to give this context as it was pretty bad) and when he got groans and reactions from the audience, he replied “That was a new joke. I see we are finding the line together. And there it is.” That got a good laugh and got him off the hook. I think in nimble marketing organizations, we do the same thing. Sometime we try new things. New campaigns. New platforms. New experiments and A/B tests. We try out new channels. We try out different messages. And we win some and garner industry accolades and business success. And we lose some, earning only groans or sarcastic More…

How Long is 50,000 Hours?

The typical lifetime of Leyard and Planar’s LCD display solutions is 50,000 hours. That means that if you turn on a Clarity® Matrix® LCD Video Wall right now, the LCD displays will run for 50,000 hours before they achieve half-brightness (and will continue to run beyond that, of course). Let’s put it all into perspective: 50,000 hours is over 5 years 50,000 hours is over 297 weeks 50,000 hours is over 2,083 days What could you do in 50,000 hours? You could travel to the moon and back 347 times. You could drive from Los Angeles, California to New York, New York 2,439 times. You could have Lord of the Rings Trilogy marathon over 73 More…
