Section 1: Introduction
Product Description
This 27-inch ET2799L touchscreen display combines Elo’s latest developments in touch technology and display design with the reliability for use in full environments. It
is designed to meet EN62368-1 Part 22 when properly mounted.
This 27-inch ET2799 touchscreen display incorporates a Full HD 1920x1080 resolution, 24-bit color, 1500nit brightness, active matrix thin-film-transistor LCD panel
to provide high quality display performance. The LED backlight significantly reduces power consumption and eliminates mercury (compared to CCFL-backlit panels).
The ambient light sensor on the front of the screen offers added functionality to adapt the brightness setting to the environmental lighting conditions, helping to
ensure the best user experience in any exterior setting.
With a vandal-resistant (IK10) anti-glare screen, the display is designed for optimal operation in harsh field conditions. The USB 10-point touch operates even if
water or other elements are on the screen, and this product also supports various other touch capabilities: RS232 Touch with 2 touches (via a separate optional
cable kit: E810917), and 2 touches with up to 6mm of cover glass on top of the touchscreen.
The addition of built-in thermal and humidity sensors and 6 internal fans help to prevent the display from overheating. The touchscreen display is also equipped with
a Real Time Clock which gives you the ability to plan a power schedule.
Other features that enhance this LCD monitor’s display performance are Plug & Play compatibility with Windows, Android, or Linux operating systems, tethered
remote on-screen display (OSD) controls for easy access when integrated, simplified flush mounting design for easy IP66 and NEMA4X sealing, flexible flush, VESA,
and touch thru mounting options, and a GPIO connector for additional component control requirements inside the enclosure. The display also supports 12V –24V
DC power input making it very easy to integrate with your current power solution.

Section 4: Operation
Power
The touchscreen display ships in the ON state.
Toturn the touchscreen display on or off, attach the OSD remote via the RJ45 connector and press the touchscreen display power button on the OSD remote once.
The power status LED on the OSD remote functions according to the following table.
Touchscreen Display/Computer Module Status LED Status
OFF OFF
SLEEP PULSING
ON ON
The system consumes low power when in SLEEP and OFF modes. For detailed power consumption specifications, refer to technical specifications on the Elo
website http://www.elotouch.com
Touching the screen will bring the attached host PC out of SLEEP mode (similar to moving the mouse or pressing a keyboard key).
To improve reliability and reduce power consumption, disconnect the AC power cable from the monitor when long periods of disuse are planned.
Touch
Your touchscreen display is factory-calibrated and should not need manual calibration (unless the input video is not fully scaled to the native resolution, or the touch
experience needs to be calibrated to a specific user).

User Manual: ET2799L Touchscreen
UM600526 Rev B, page 10 of 31
Projected Capacitive Touch Technology
When connected to Windows 7, and 10 or later computers, the touchscreen display can report 10 simultaneous touches. When connected to Windows XP computers,
the touchscreen display reports single touch.
No additional drivers are required for this technology to work with Windows 7, and 10 or later, it uses Windows HID drivers.
Please refer to Chapter 2, Section “Installing the Touch Technology Software Drivers” to find instructions to download touch drivers for RS232 touch with 2 touches.
Gesture Support
The Projected Capacitive Touch enables several gestures that support single and multiple touches. Refer to theMicrosoft Website https://docs.microsoft.com/en-
us/windows/win32/wintouch/windows-touch-gestures-overview on the various gestures that are supported in Windows 7, and 10.
Video
A display’s native resolution is its width and height measured in number of pixels. Generally, for best performance, animage displayed on this monitor will look best
when your computer’s output resolution matches this monitor’s native resolution.
For computer output resolutions at non-native resolutions, the monitor will scale the video to its panel’s native resolution. This involves stretching or compressing the
input image as needed in the X- and Y-dimensions to fit the display’s native resolution.An unavoidable byproduct of the scaling algorithms is a loss of fidelity when the
computer’s output video image is scaled by the monitor to fit the display. This loss of fidelity is most apparent when viewing feature-rich images at close distances (for
example images containing small-font text).
Your touchscreen display will likely not require video adjustments. However, for analog VGA video, variations in video graphic card outputs may require user
adjustments through the OSD to optimize the quality of the monitor’s displayed image. These adjustments are “remembered” by the touchscreen display. Also, to
reduce the need for adjustments for different video mode timings, the monitor correctly scales and displays some of the video industry’s most common video timing
modes. Refer to the technical specifications for this monitor at http://www.elotouch.com for a list of these Preset Video Modes.

Temperature Control
The monitor contains a thermal sensor that provides the user with real-time temperature readings. This reading can be found by opening the OSD menu:
Information ►System Temperature. If the monitor is operated above the operating temperature limit, the monitor will go into “Thermal Protection Mode” which
will turn on the internal fans to dissipate heat until the internal temperature is back within operating range. If the temperature continues to rise and reaches 90°C,
brightness will be limited. If the internal temperature decreases below the Thermal Protection Mode temperature for at least five minutes, normal operation is
resumed.
If the temperature exceeds 70 °C, the user will be prompted to shut off the monitor within sixty seconds. The following icon will appear in the Main
Menu. This will indicate that the Thermal Protection Mode is active.
If the system is not manually turned off within sixty seconds or the display internal temperature is not reduced below 70 °C, the display will
automatically turn off to prevent permanent damage.
