LCD Screen Size, Viewing Angle, Response Rate, Contrast Ratio, Brightness, Orientation, Wall Mounting

In this lesson, we explore the attributes of the LCD monitor and explain their interrelationships and how they work.

We begin with screen size which can be measured in inches or centimeters.  We’ll explain the concept of “viewing angles” which are measured in degrees, and how this differs in relation to the “viewable area” of the CRT monitor.

Response rate is the amount of time it takes the monitor to respond to a request for display service and why a large screen monitor with a low response rate would be preferred.

Contrast Ratio is the difference between the brightest white and the darkest black that a monitor is able to display.  So you’ll learn how to determine if a display returns a dynamic distinction between colors and in particular between light and dark images, between shadows, if there is glare.  The higher the contrast ratio the better, which is also impacted by Brightness, and we’ll explain why.  You’ll learn what a Candela is, and how you can determine when a new display is required.

We will examine Orientation and demonstrate how monitors can change from a portrait or taller orientation vs. a wider or “landscape” orientation and the importance of mounting.

Mounting capabilities for flat screens vary from model to model; some have a dual orientation which means they can be mounted as both portrait and landscaped, while others do not.  That is a determination of the OEM, so here proper research is required. We’ll demonstrate how to setup your LCD for wall mounting, and how to examine the cabling and layout configurations for the use of the additional ports each LCD contains.

Lastly, we hold a discussion on privacy and anti-glare filters by explaining what they are, how they look, how they work and discuss the scenarios where they would be needed.
