The highest of rack mount monitors is measured in rack units, or RU. One RU = 1.75”.
As with other industrial monitors, rack mount LCD monitors offer a wide range of features. Key considerations include:
• Number of LCD Screens: How many images do you wish to display simultaneously? Popular sizes feature dual 7” screens or triple 5” screens. You can also have single LCD screens up to 20” in size, or up to ten 2” screens.
• Screen Resolution: Higher resolution screens = better image quality. But also be sure to match them to your video input signals. Why use HD panels to display a 640 x 480 image?
• Wide Viewing Angle: Narrow viewing angle screens means the images wash out or colors invert when viewing the screen from an angle. Look for 130º or more.
• Brightness: The LCD must be bright enough for your environment. 300 nits or more is optimal.
• Touch Screen: This option often greatly assists user interaction.
• Adjustability: Look for the ability to control each LCD individually. An OSD (On Screen Display) is very helpful.
• Tilt: Rack mount monitor enclosures typically have “handles” at both ends to enable the user to tilt them up or down for optimal viewing angle. 180º tilt is best.
• Video Inputs: Be sure each LCD screen has a variety of video inputs.
• Tally Lights indicate which of the screens is the “live” feed.
• LED Backlights produce brighter and more uniform images than fluorescent backlights.
Industrial monitors in rack mount monitor enclosures provide convenient mounting in a space-saving design. Enabling operators to view multiple screens simultaneously can greatly improve their efficiency.
