Touch Screen Calibration and Display Settings

Updated 2 weeks ago · 8 min read

Touch screens are a critical component of every Foto Master photo booth. They provide the guest-facing interface where users start sessions, preview photos, and interact with your booth experience. A properly calibrated touch screen ensures accurate tap responses, and correct display settings keep the on-screen image looking sharp and properly oriented. This guide covers calibration, configuration, and troubleshooting for all Foto Master booth types.

Touch Screen Types by Booth

Identify the booth model, purchase date and installed touch controller before choosing a calibration utility. Hardware changed over time; the booth name alone is not enough to choose a driver.

Controller and Purchase-Date Reference

The following model-specific information was confirmed by Foto Master Support on 7 September 2026:

Booth model	Touch hardware / controller	Applies from
Mirror X Booth (MXB)	Touch foil with ET Controller	May 2021
Mirror Air Booth (MAB)	Touch foil with ET Controller	April 2021
Tower Mirror Booth (TMB)	Touch foil with ET Controller	25 April 2021
Beauty Mirror Booth (BMB)	Touch foil; confirm the installed controller before choosing a utility	2019
Mirror Me Booth (MMB)	MMB-IR touch overlay	June 2018
Retro Mirror Booth (RMB)	Touch foil with XT Controller	April 2019

The month/year entries do not specify an exact changeover day. This table does not identify the controller in earlier units. For a purchase near the changeover, an unknown date, or a second-hand or modified booth, check the installed controller name rather than inferring it from the model or resale date. If you cannot identify it, send Support the booth model, original purchase date if known, and a photo of the controller label or calibration application's name.

The Mirror Me MMB-IR overlay uses an infrared frame mounted around the mirror glass, connected to the PC by USB. Mirror X, Mirror Air, Tower, Beauty and Retro use touch foil mounted behind the mirror glass in the configurations listed above. Similar touch-foil configuration does not mean ET, XT, SiS and MMB-IR software or calibration settings are interchangeable.

Tip: If touch response feels inaccurate or unresponsive, verify that the touch device is properly connected via USB and recognized by Windows before launching the booth software.

Touch Foil Calibration Procedure

Touch foils used in MXB, MAB, TMB, BMB, and RMB booths may occasionally require calibration to maintain accurate touch registration. If guests press one area of the mirror but the booth responds as though a different area was touched, the touch foil likely needs recalibration.

When to Calibrate

After major physical adjustments to the mirror, display, or touch components.
After a Windows update that may have changed display or touch driver settings
When touch responses are consistently offset from where guests press
After transporting the booth to a new event (vibration during transport can occasionally shift calibration)

Calibration Steps

Close FMX and any other full-screen applications.
Match the installed controller to the model/date reference above before opening the booth's calibration utility, usually stored in the "touch" folder on the PC. Do not install a different controller's driver to make an unrelated guide match.
ET Controller: Mirror X from May 2021, Mirror Air from April 2021 and Tower from 25 April 2021 use ET in the configurations above. Use the ET utility and its matching instructions. The XT guide below does not establish ET button names, threshold values or target counts. If the correct utility or instructions are missing, ask Support for the guide matching the installed controller.
XT Controller: For a Retro or Beauty Mirror Booth confirmed to have XT, use the XT touch-foil calibration guide. Beauty Mirror's touch-foil identification alone does not confirm XT.
MMB-IR or SiS: Use the instructions for that installed touch system, not the ET/XT procedure. Contact Support if its identity or the applicable guide is unclear.
Complete all targets shown by the matching calibration utility and save when prompted. Target count and controls can vary; do not assume every utility presents four points.
Test the corners and center of the screen, then reopen FMX and test the guest-facing buttons.

Tips for Accurate Calibration

Use your fingertip, not a stylus or pen, during calibration -- this matches how guests will interact with the booth
Tap the exact center of each crosshair target. Rushing through calibration leads to inaccurate results.
If the first calibration attempt still feels off, reset the calibration and try again
Make sure nothing is pressing against the touch foil or mirror surface during calibration (remove any magnetic accessories or items leaning against the glass)

Display Settings

Resolution

Set the display resolution to the native resolution of your touch screen for the sharpest image quality.

Right-click the Windows desktop and select Display settings
Scroll to Display resolution and select the resolution marked as (Recommended) -- this is the monitor's native resolution
Click Keep changes

Common native resolutions for booth displays:

1920x1080 (Full HD) -- Most common for booth touch monitors and Mirror Me displays
1080x1920 (Full HD, portrait) -- Same resolution in portrait orientation (TMB, portrait-oriented booths)
3840x2160 (4K) -- Higher-end booth displays

Orientation

Many Foto Master booths run their displays in portrait orientation rather than the standard landscape. You must set the Windows display orientation to match your physical monitor mount.

Open Display settings
Under Display orientation, select the correct option:
- Landscape -- Standard horizontal orientation
- Portrait -- Rotated 90 degrees counterclockwise
- Landscape (flipped) -- Upside-down horizontal
- Portrait (flipped) -- Rotated 90 degrees clockwise
Click Keep changes
Verify that the FMX interface appears correctly (not rotated or upside-down)

Tip: If you change the display orientation and the touch input no longer aligns with what is on screen, you will need to recalibrate the touch screen after changing the orientation. Windows calibration data is tied to the current orientation setting.

Scaling

Windows display scaling affects how large UI elements appear. For booth use:

100% scaling -- Recommended for most booth setups. FMX is designed to run at 100% scaling.
If text and icons appear too small on a high-resolution display, try 125% or 150%, but test FMX thoroughly to make sure all interface elements still fit correctly.

External Display Configuration

Some booth setups use a secondary external display -- for example, an attraction screen facing outward to draw guests in, or a slideshow display showing recent photos.

Setting Up a Second Display

Connect the second display to your booth PC via HDMI or DisplayPort
Open Display settings
Windows will show both displays. Click Detect if the second display does not appear.
Choose how the displays work together:
- Extend these displays -- Recommended. FMX runs on the primary touch display, and your attraction content runs on the secondary screen.
- Duplicate these displays -- Shows the same content on both screens. Less common but useful for simple setups where you want guests on both sides to see the same view.
Set the primary display (the touch screen) by selecting it and checking Make this my main display

Using FMX with External Displays

FMX can output to a secondary display for attraction screens, live slideshow views, or queue displays. Configure the secondary display output in FMX under Settings > Display and assign what content should appear on each screen.

Troubleshooting: TV Display "No Signal"

If your booth display shows "No Signal" instead of the Windows desktop or FMX interface:

Check Physical Connections

Verify the HDMI or DisplayPort cable is firmly seated in both the display and the booth PC
Try a different cable -- HDMI cables can fail, especially after repeated booth assembly and teardown
Try a different port on the booth PC if one is available
Make sure the display is set to the correct input source (use the display's remote or on-screen menu to select HDMI 1, HDMI 2, DisplayPort, etc.)

Check Display and Graphics Settings

Press Windows key + P and select PC screen only first, then try Duplicate or Extend to force Windows to detect the display
Right-click the desktop, open Display settings, and click Detect to force Windows to scan for connected displays
Check that the display resolution is set to a resolution the display supports. If the resolution is set too high, the display may not be able to show the image.
Update your graphics driver (Intel, NVIDIA, or AMD, depending on your booth PC) -- outdated drivers can cause detection issues

HDMI-Specific Issues

Long HDMI cables (over 15 feet) can cause signal loss. Use a shorter cable or an active HDMI cable/extender for longer runs.
HDMI adapters and splitters can introduce compatibility issues. Use a direct connection whenever possible.
Some displays require an HDMI handshake -- power on the display first, then the booth PC, so the PC detects the display during startup.

If Nothing Works

Connect the display to a different computer (laptop, another PC) to confirm the display itself is working
Try a completely different display on the booth PC to rule out a graphics card issue
If the display works with other devices but not the booth PC, the graphics card or its driver may need attention

Tip: At events, always carry a spare HDMI cable and a small backup monitor. A display failure does not have to end your event if you have a replacement ready.
