The Elo Touch Solutions 1990L (manufacturer part number E328497) is a 19-inch Open-Frame touch monitor designed for use in industrial, commercial, or point-of-sale environments. The device features an LED-backlit TFT-LCD display with a resolution of 1,280 × 1,024 pixels and an aspect ratio of 5:4. The touch function is based on IntelliTouch surface wave technology, enabling single-touch operation. The monitor is delivered without a power supply (Power Brick) and offers HDMI, VGA, and DisplayPort connections, allowing flexible integration into existing systems.

Applications
This monitor is particularly suitable for applications requiring a robust, integrated control interface, such as cash registers, industrial control systems, information displays, or in the hospitality industry. As an Open-Frame model, it can be directly installed into enclosures or cabinets, making it easy to integrate into existing mounting solutions. The IP67 protection rating is not specified, so the device is not intended for direct outdoor use or in heavily contaminated environments.

Features and Specifications in Detail
The screen offers a brightness of 250 cd/m², which reduces to 225 cd/m² when the touchscreen is active. The contrast ratio is 1,000:1, ensuring clear display of text and graphics. The 5 ms response time minimizes motion blur for moving content. Viewing angles are horizontal ±85° and vertical ±80°, ensuring good visibility from various positions. The integrated touch function allows direct interaction with the display, using IntelliTouch technology based on surface waves that are disturbed by touch to determine position.

Technology Explained Simply
The display uses TFT-LCD technology with LED backlighting, ensuring even brightness distribution and longer lifespan. The resolution of 1,280 × 1,024 pixels corresponds to the XGA standard and is sufficient for displaying text, tables, and simple graphics. HDMI, VGA, and DisplayPort connections allow flexible connectivity to various computers, set-top boxes, or other signal sources. Integrated USB and RS232 ports enable control of the monitor via external devices, for example, for configuration or diagnostics. Power is supplied via an external power supply, which is not included in the package.

Compatibility and Accessories
Additional components are required for operation, particularly an external power supply. Suitable accessories include the ELO EXTERNAL 50W POWER BRICK, which ensures reliable power supply. For mounting, the 1937L/1939L FRONT-MOUNT BEZEL and 1937L/1939L RACK-MOUNT BRACKET are available to integrate the monitor into front-panel or rack installations. Cable adapters such as the ELO KIT CABLE DVI D TO DP or ELO KIT CABLE DP TO DP allow adaptation to different connection types. A REPLACEMENT OSD CONTROLLER is available if the integrated control unit fails.

Mounting and Installation
The monitor is designed as an Open-Frame model, meaning it is delivered without an integrated stand and must be directly installed into an enclosure or console. VESA mounting follows the 75 × 100 mm standard, enabling universal attachment to VESA-compatible brackets. Dimensions without stand are 41.47 cm (width) × 5.00 cm (depth) × 34.27 cm (height), with a total weight of 6.78 kg. Installation requires the use of an external power supply and wiring of connections according to the specific application requirements.

Operational Advantages
The monitor is characterized by high operational reliability and long service life. The LED backlighting consumes less energy than traditional CCFL technology and has a longer lifespan. The integrated touch function enables direct, touch-based interaction, simplifying operation in many applications. Typical power consumption during operation is 22 W, 1.5 W in standby mode, and 0.5 W when powered off, reducing energy usage compared to other monitors. The combination of robust design and versatile connectivity makes the 1990L a reliable solution for professional applications.

Note: Included Items
The device is delivered without an external power supply (Power Brick). Integrated USB and RS232 connections are present, but no external power supply unit is included. Mounting is without a stand, so a suitable bezel or bracket must be purchased separately.
