Le choix du bon moniteur pour vos clients commerciaux peut être difficile en raison des nombreuses options et du fait que la technologie qui les sous-tend évolue rapidement. Ce guide vous guidera à travers les différents types de moniteurs et leurs caractéristiques, vous permettant de choisir celui qui convient le mieux à vos clients.
Screen mode helps determine the appropriate resolution to display content. Choosing the right screen mode ensures that the content matches the display's capabilities, resulting in crisp and properly proportioned visuals. This knowledge forms the basis for delivering high-quality presentations and multimedia experiences in professional AV installations.

Remember that screen size today is determined by a diagonal measurement of the monitor. A simple calculation will be enough to find the right screen size for your customer. First, measure the distance between where the monitor will be placed and where you plan to look at the monitor. Divide the total distance in inches by two and the resulting number will be the minimum diagonal measurement of the monitor you should choose for your client.

Mounting brackets attach to the back of a monitor and provide a mounting point for a monitor arm or other type of mount. They are typically used with monitors that do not have built-in VESA mounting holes.
VESA mounts are a standardized mounting system for LCD and LED monitors and are available in a variety of sizes and patterns, so it's important to choose a mount that is compatible with your monitor.
The monitors can also be mounted on desks, walls, or ceilings. Desk mounts attach to the edge of a desk or table and allow you to adjust the height, tilt, and rotation of your monitor. Wall mounts allow you to mount your monitor to the wall to save space or create a more streamlined look. Ceiling mounts allow you to hang your monitor above it, which is a good option for standing desks or to create a more immersive viewing experience.
When choosing a monitor stand, it is important to consider the size and weight of your monitor, the type of desk or wall you will be mounting the monitor on, the desired range of motion for your monitor, and your budget.

Refresh rate refers to the number of frames that are displayed on the TV screen per second. Refresh rates are expressed in hertz, so a refresh rate of 75 Hz means that the image is refreshed 75 times per second. The higher the refresh rate, the smoother and less blurry the image.

The aspect ratio of a monitor is very relevant because it directly affects the shape of the screen and the way the content is presented. The aspect ratio is the ratio of the width to the height of the screen. The choice of aspect ratio depends on the intended use of the monitor. Examples of use:
4:3 - Digital Signage, Medical Imaging, Old Televisions and Computer Monitors
16:9 – Most modern TVs and computer monitors, movies, TV shows, and video games
16:10 - Professional monitors, laptops

Monitor backlight technology plays a crucial role in improving display quality. There are mainly two types: direct LED and edge LED.
Direct LED, also known as LED (light-emitting diode), involves placing a set of LEDs directly behind the display. This configuration allows for precise local dimming, resulting in superior contrast and black levels.
In contrast, the edge LED positions the LEDs along the edges of the display. While it is more energy-efficient and allows for slimmer designs, it may have limitations in terms of uniformity and contrast compared to direct LED.
WLED (white LED) is a common backlight source, using blue LEDs with a phosphor coating to produce white light. It offers efficiency and longevity, contributing to the vibrant visuals we expect from modern monitors.

Les technologies d'écran LCD (affichage à cristaux liquides) et LED (diode électroluminescente) sont couramment utilisées dans les moniteurs. Les LCD utilisent des cristaux liquides pour manipuler la lumière, tandis que les LED utilisent des diodes semi-conductrices pour le rétroéclairage. Les moniteurs LED sont généralement plus économes en énergie et offrent un meilleur contraste et une meilleure luminosité. Les LCD sont toujours courants mais souvent dans des modèles plus anciens, tandis que les LED dominent le marché en raison de leurs performances supérieures.
Les moniteurs LCD sont couramment utilisés dans les environnements éducatifs, les soins de santé, les systèmes de point de vente (POS), la signalisation numérique, les transports en commun, la sécurité et la surveillance, ainsi que dans le contrôle du trafic aérien. Les moniteurs LED sont utilisés dans une grande variété d'applications, grâce à leur efficacité énergétique et à leurs performances supérieures. Ils sont généralement trouvés dans les panneaux d'affichage numériques et la signalisation, les stades de sport extérieurs, les affichages d'informations dans les aéroports et les vitrines de vente au détail.
