There is an immense variety of digital signage displays in the market, and it can be difficult to decide which one to buy. When deciding on what display to purchase, you need to consider such factors as resolution, connectivity, contrast ratio, and size. However, it’s also important that you check the features and capabilities of each model.
This article outlines some of the most important features for outdoor digital signage singapore, digital retail interfaces, and event management systems.

The resolution of a digital signage display is the width and height in pixels that the graphic will be displayed. This is also referred to as “width/height”. For example, 1280 x 720 would be equal to full HD. The lower pixel count translates into more detailed graphics but also increases the pixelation effect. One example is that an 800 x 600-pixel display will display more text per line than a 1024 x 768 display on a traditional CRT monitor.
Unlike traditional monitors, these displays have resolutions that can only be found in an HDTV. Therefore, big is best when it comes to resolution.
The same unit will have a different number of pixels on different sides of the display. For example, if there is a 1″, 2″, 4″ and 6″ display in the same unit, the width can be between 1″ and 2″. The height will be between 2″ and 4″. There can be a variety of resolutions for digital displays, such as 800 x 600, 1024 x 768, 1280 x 720, 1366 x 768, and 1920 x 1080.
There are different types of resolutions available in outdoor digital signage in singapore. The most common is HDTV (HD Ready), Full HD, and Ultra HD. Some vendors also support a variety of other standards such as 1080p, 4K, or 3K/FHD. These are called desktop ready, but they also come in a variety of formats such as VGA and HDMI.
The most common digital signage display connectivity is just VGA and HDMI. Most vendors include both of these options to allow the display to be used with a PC. However, a variety of other connectivity standard protocols are also supported including DVB-T, DVB-C, ATSC, FCC, and NTSC.
Connecting a display to a PC is fairly simple. Desktop computers have an analog VGA port, while laptops and tablets may have an HDMI or mini-display port. In addition, some vendors support a wide array of USB ports. The display will be able to recognize these and identify the right video input.
Sadly, these displays are limited when it comes to connectivity as they don’t have built-in wireless connectivity. The only options are compatible wireless USB dongles or Bluetooth. Wired networks can be used but there may be a large range of low bandwidth devices that will use the same network.
Outdoor digital signage singapore has a variety of sound quality settings, starting at just mono and high for background music, to Stereo and Dolby Digital for full surround sound. A few displays currently also offer “Surround Sound” or “DTS Sound”. This feature usually either has a multi-speaker setup or a 5.1 or 7.1 surround sound decoder built-in.
When it comes to sound quality, consumers can choose between mono and stereo. Other options might be “Digital Sound” or “Dolby Digital”. When you connect the display to a multimedia source, the same source will be played on both the speakers and on headphones connected to the audio output port. If a dedicated multimedia source is used, as opposed to just a PC/tablet/smartphone, they can have multiple audio outputs.
Some digital signage displays use DTS Interactive, a proprietary format that is just a special version of Dolby Digital. If it presets to 5.1 or 7.1, the signal will either go to the speakers or headphones.
The contrast ratio is used to measure the contrast between backgrounds and foregrounds such as text and graphics. This ratio by itself is not an accurate measurement, but rather has been quantified by various groups over many years. These groups allow the ratio to be measured across all the different industry-standard options. Therefore, when comparing two displays that have the same contrast ratio measurement, they will have a similar effect on having a good display. A high contrast ratio is desirable as it allows greater detail in text and graphics. Displays with a low contrast ratio also suffer from glare or brightness in some regions of the display at certain angles.
This measurement is the most important when considering whether a display is good enough. Contrast is an important part of having a good visual experience. A narrow viewing angle display might be able to measure high contrast, but it won’t look good when you’re not looking at it straight on.
Some digital signage displays allow you to choose between different scanning modes, which are usually in the following order: progressive, interlaced, and “no scan”. Interlaced scans in two different fields, the first being one half of the image and the second being the other half. “No scan” is just a 1:1 representation of what you see on your computer/display at any given time. It doesn’t try to make it look better or sharper. Progressive scans are better than interlaced when it comes to text and graphics as it captures an entire picture at once, instead of capturing two fields between which there will be a slight gap in space.
Some businesses use outdoor digital signage Singapore as part of a loyalty program. For example, customers can be given a loyalty card, key fob, or other electronic devices that they can use to get rewards and benefits. Every time they make a purchase, the digital display will provide a coupon or discount that can be used during their next visit. By using digital signage services to display coupons, the business owner can provide more timely and relevant offers while at the same time increasing customer loyalty.
