DVI/HDMI vs VGA in digital signage

As DVI and HDMI connections become more and more widely used in digital signage, we are often asked: which is better, DVI (or HDMI) or VGA? There is no clear answer to this question.

First, let’s get some basic knowledge of the elements. DVI and HDMI are exactly the same as one another regarding image quality and resolution. The main differences between HDMI and DVI are that HDMI carries audio and video signal; further more HDMI uses different types of connectors. Technology wise both HDMI and DVI uses the same encoding technology, and for that reason DVI source can be connected to an HDMI connector on display, or vice versa, with a DVI/HDMI cable, with no use of signal converter

What are the difference between DVI, HDMI and VGA?

DVI/HDMI and VGA Video are all video signals which support a variety of resolutions, each one of them deliver the signal from source to display in different ways. The main difference is that DVI/HDMI delivers the signal in a digital format. VGA is an analog format, which deliver the signal, not as a digital stream, but as a set of varying voltages representing the red, green and blue components of the signal.


DVI/HDMI and VGA deliver signals as red, green, and blue color components, together with sync information. The DVI/HDMI standard delivers these along three data channels in a format called T.M.D.S., which stands for “Transmission Minimized Differential Signaling”. This basically involves a blue, red and green sync that are added, and separate the channels

VGA is delivered, almost similarly, with the color information split up three ways. However, VGA uses a color difference type signal, which consists of Luminance, the green red or blue channel, representing the total brightness of the image. The sync pulses for both horizontal and vertical are delivered on the Y channel.

Both HDMI/DVI and VGA signal types are fundamentally quite similar; they break up the image in similar ways, and deliver the same type of information to the display. How they differ, as we’ll see, will depend to a great extent upon the particular characteristics of the source and display devices, and can depend upon cabling as well.

What is better Digital or Analog?

Digital signal transfer, it is assumed, is error-free, while analog VGA signals are always subject to some amount of degradation and information loss. There is an element of truth to this argument, but it tends to back fire in real-world testing.
First, there is no reason to get signal degradation of an analog VGA signal in digital signage installation where the distance between the player and the screen is short. Digital signage installation in a large retail or education facility for example can present a challenge for analog cabling. But, it is a flawed assumption to suppose that digital signal handling is always error-free. DVI and HDMI signals aren’t subject to signal error correction like downloading a file; once information is lost, it’s lost for good. That is not a consideration with well-made cable over short distances, but can easily become a factor at long distance.

So what should I use for best Image Quality?

DVI or HDMI signal formats is pure digital. There are some arguments that by taking a digital signage player and connecting it straight into digital connector as a DVI or HDMI signal, and then delivering that digital signal straight to the digital signage display, there is a sort of a perfect no loss of information signal. If the display itself is a digital display like LCD, the signal never has to go through digital to analog conversion and therefore is less altered on the way.

The Role of Cable in picture quality

Picture quality, in general, should not be a significant factor in the DVI/HDMI in short distance bellow 50 ft, as long as the cables are of high quality. There are, however, issues when you centralize your player and you send the signal to a display 200ft a way. In this kind of environment analog or digital signal will have problem without using DVI/HDMI/VGA over cat 5 extender. Without using these extenders signal quality issues can come into play.
DVI and HDMI connections, uses SDI technology (serial digital video) which was designed originally to run on coax where impedance can be controlled and compensate. DVI/HDMI signals are run balanced, using twisted-pair cable technology which control impedance to about +/- 10%, and for this reason, are subject to the digital cliff phenomenon. Up to some distance, a DVI or HDMI cable will perform just fine and will not compromise the ability of the display device to reconstruct the original bit stream without information lost.
As we run longer distances, the ability to reconstruct the bit stream decreases. As a result unrecoverable bit errors start to occur. As distance increases more information is lost to a point that the display becomes unable to reconstitute enough information to render an image. A DVI/HDMI cable that works perfectly at 40 feet may not work at 80 feet. It is very hard to determine the exact distance a DVI or HDMI cable will fail, most quality HDMI /DVI cable will work fine up to 50ft.

The Answer: It Depends

So, which is better, DVI/ HDMI or VGA? The answers unsatisfying, but the truth is that it depends. It depends upon your source player, type of cable, type of display and the distance, and there’s no good way, in principle, to say in advance whether the digital or the analog connection will draw a better picture. You may find that some digital signage player looks better through its DVI or HDMI output, while a different player using VGA output better image through its RGB cable, on the same display. Some installers reports ghosting/blurriness with text using analog and when switching to digital interface made things much crisper. On the other hand, other installers who used DVI/HDMI long cable found that the text was blurry, colors were off and the image didn’t scale to fit correctly and got no issues at all with VGA. In this case, if you are using cable longer than 50ft you should use VGA over Cat5/6 extenders that will control picture quality over distance over 50ft like Minicom.

 

1080p Vs 1080i in digital signage

What is 1080p

1080p resolution which is 1920x1080 pixels is the latest HD state for the art resolution. Digital signage display supporting 1080p displays are capable of displaying every pixel of the highest resolution HD broadcasts. In reality, they offer more than twice the resolution of today’s 1280x720 or 720p. Companies refer to this kind of resolution as true or Ultra HD

1080p Vs 1080i

1080i, is the first generation of HDTV technology, this technology can actually display 1920x1080 resolution but the 1080i generate the images in an interlaced format, (now we know what is the “i” for “interlace”). In a the old technology Tube base or projection TV technology, mostly called CRT, using 1080i technology where the frame get drawn on the screen sequentially: the odd-numbered lines of resolution appear on your screen first, followed by the even-numbered lines all within 1/30 of a second. In 1080p (P refer for progressive such as 720p, and 1080p) all of the lines of resolution are drawn sequentially in a single pass, which makes a faster, cleaner image, especially with sports and other fast motion content, as opposed to CRT tubes display technology.


This rough animation compares progressive scan with interlace scan, also demonstrating the interline twitter effect associated with interlace. On the left are two progressive scan images. Center are two interlaced images. Right are two images with line doublers. Top are original resolution, bottom are with anti-aliasing

How much extra does a 1080p Display cost

Today the 1080p technology is getting cheaper fast. If you take a look at the product lines of Samsung and LG you can see that, on average, you can expect to pay about $500 extra for the progressive technology.

Why you should buy or not buy a 1080p display for Digital Signage

Obviously, the quality of the content you’re viewing is very important, but so are screen size and how far your audience from the display. Indeed, our digital signage guru, reports that the extra sharpness provided by the 1080p technology is noticeable only when watching 1080i content on a very large display. Comparing a 50-inch 1080p to a 50-inch 720i digital signage display, for example, you’ll be hard-pressed to notice more detail with 720i sources, especially from farther than 10 feet away. Even if you can see the difference, it will be much less obvious. In reality the performance of 1080p is not the extra sharpness you’ll be seeing, but rather, the smaller, more densely packed pixels.
If you are using 1080p for your digital signage player , you should be aware that you may not necessarily get to use all that extra resolution even if you have the right high-end graphics card. For instance, the Sharp set we tested allows you to max out at only 1,280x1024 resolutions.
If you’re thinking of deploying big digital signage signs like 60 inch or larger , the extra resolution may make it worth the difference as long as you have a high quality 1080p content to feed into the player
