The Dell SX2210T Monitor has touch screen capabilities. Drivers must be installed and the USB cable from the monitor connected to the computer for the touch screen feature to work. The touch screen can work either with your fingers or a stylus. The touch screen has many customizable options similar to other touch input devices. The option screens can be accessed from the Control Panel by clicking Pen and Touch.

	Note:
	Not all versions of Windows Vista and Windows 7 will have all of the Pen and Touch options metioned. This is a limitation of the verison of the operating system. See the table below near the bottom of this document outlining the avaialble touch features.

Pen Options Tab

The Pen Options tab has options to adjust tapping speeds and Spatial Tolerance under the Settings button (Figure 1).

Flicks Tab

Flicks allow a user to perform common actions by simply using a short stroke of the stylus or finger. The Flicks tab allows a user to define the flick action and the sensitivity in which a flick action is registered (Figure 2).

Touch Tab

The Touch tab has options that enable your finger to be used as an input device and enable gestures. In the Touch actions section are options to adjust double-tap speed and the press and hold time for right-click. Under the Touch pointer section is the option Show the pointer when I'm interacting with items on the screen which will cause a transparent image of a mouse to appear when tapping (Figure 4).

Panning Tab

Panning can be enabled on this tab. The inertia setting allows for the screen to continue to scroll like spinning a wheel once your finger has been lifted. The inertia resistance setting can be increased which will cause the scrolling to stop sooner or decreased which keeps it moving longer (Figure 5).

Multi-Touch Gestures
Pan Move two fingers in the desired direction to pan-scroll the selected object.   Note:     Some programs will pan with only 1 finger such as Windows Photo Viewer.
Zoom Allows you to increase or decrease the magnification of the screen content/object. Moving two fingers apart on the touchpad zooms in on the active window. Moving two fingers closer together on the touchpad zooms out on the active window.

• Touching the screen has no effect. It does not register any input.
  1. Ensure the USB upstream cable is firmly seated to the connector on the bottom of the monitor and the port on the computer. Try a different USB port on the computer. Test with a different upstream USB cable if available.
  2. Ensure the USB ports are working on the computer by testing with a mouse or keyboard. Install the chipset or USB drivers on the computer if needed.
  3. Install the Touch Monitor drivers. Ensure they are installed by checking device manager under Human Interface Devices for NextWindow 1950 Touch Screen.
  4. Run the diagnostics by opening the Control Panel and clicking Touch Screen Tools. Click the Run Diagnostic Test button and one of the following messages will be displayed:
     • Pass
     • Touch Screen is not connected. Reconnect screen and try again. If problem persists, call customer support.
     • Please clean the screen and if problem persists, call customer support. (If there is a blockage in the optical path, the diagnostic routine will display a red “X” on the Display Configuration window).
       
       
• The touch inputs are not accurate. The pointing or tap inputs are not where the finger/stylus is.
  1. Ensure the monitor resolution is set correctly. The SX2210T should be set to 1920x1080.
  2. Clean the screen with a dry lint free cloth or use an approved monitor cleaner. Excessive smudging could cause the touch screen to not properly register inputs.
  3. Run the calibration by opening the Control Panel and clicking Touch Screen Tools. Click the Calibrate button. The text on the Calibrate button will change to say Calibration in Progress and the mouse pointer will go to the upper left corner. Press and hold your finger still on the pointer until the pointer moves to the upper right corner. Repeat this process for all four corners. The button text will change back to say Calibrate and the mouse will then return to the center of the screen. The calibration will then be complete.
     
     
• The monitor will not wake up when touched.
  1. Hold a touch on the screen for a few seconds before the computer will wake from sleep mode.
  2. Check that monitor driver is installed. Run the NextWindow’s 19xx driver from the CD that comes with the monitor.
     
     
• Cannot use gestures such as scroll or rotate.
  1. Find out which operating system the user has on their PC.
  2. Make sure the user is not trying to do something beyond the capabilities of their system. See the table of capabilities above.
  3. Make sure that the application software supports gestures.
