Second screen troubleshooting
Screen not detected, event or photo wall on the wrong screen, cropped image, touch on the wrong screen, dropouts: solutions for the guest screen and the photo wall.
A second screen is used for the guest screen, the live photo wall or the video feed. This article covers the most common problems and their solutions. For the normal setup, see Use multiple screens and Set up the photo wall's second screen.
Quick diagnosis
| Symptom | Likely cause |
|---|---|
| The screen shows “No signal” | Wrong source, cable, adapter. |
| BoothX sees only one screen | Screens in duplicate mode in the system, or screen not detected. |
| The event opens on the wrong screen | Screen order changed, role assigned incorrectly. |
| The edges of the image are cut off | TV overscan. |
| Touch acts on the other screen | System touch calibration. |
| The screen drops out at times | Cable too long, adapter, sleep mode. |
| The image is blurry or stretched | Non-native resolution. |
The screen gets no image
- Check the source selected on the screen (HDMI 1, HDMI 2, DisplayPort…).
- Try another cable, then another port on the computer.
- Avoid chained adapters (USB-C to HDMI to…): use a good-quality active adapter, or a direct cable.
- On a laptop, turn on video output with the system key combination (on Windows,
Windows+Pthen Extend).
BoothX sees only one screen
If the screens are in Duplicate mode in the system, BoothX sees only one. Switch to Extend mode:
- Windows:
Windows+P› Extend, or Settings › System › Display. - macOS: System Settings › Displays, turn off mirroring.
- Linux: your desktop environment's display settings.
Then, in BoothX, Settings › Screens › Identify. When only one screen is detected, BoothX says so clearly.
The wrong screen
The screen order can change when you unplug or replug a cable, or after a graphics driver update.
- Settings › Screens › Identify: each screen shows its number.
- Reassign the roles: Guests, Administration, Video feed, and the photo wall screen.
- Relaunch the event (and the wall).
Always plug the screens into the same ports from one event to the next: the order stays stable.
Screen unplugged during the event
If the guest screen is unplugged, the event switches to Paused; once the screen is plugged back in, the status badge offers Resume on screen 2 or Resume on this screen. For the photo wall, relaunch the display on the reconnected screen.
Image cut off at the edges (TV)
TVs often enlarge the image and cut off the edges (“overscan”). In the TV's picture settings, look for an option such as Actual Size, Just Scan, 1:1 or Screen Fit. Otherwise, adjust scaling in the graphics driver's control panel.
Blurry or stretched image
- Choose the screen's native resolution in the system settings.
- Keep scaling (system zoom) reasonable on the large screen.
- A 4K screen on a modest computer can slow things down: switch it to Full HD.
Touch acts on the wrong screen
- Plug in the touchscreen's USB touch cable, in addition to the video cable.
- Windows: Windows Settings › Display › Calibrate the screen for pen or touch input, then Setup, and touch the touchscreen when Windows asks.
- See Screen, touch and display problems.
Dropouts and flickering
- Long HDMI cables: beyond a few meters, prefer an active cable or HDMI over a network cable (extender).
- Sleep mode: turn off screen and computer sleep during the event. See Power, sleep and auto-recovery.
- TV power saving: some TVs turn off after a period without remote-control input. Turn this option off.
- Power supply: a screen plugged into an overloaded power strip may restart.
Orientation
After an orientation change, BoothX asks Keep this orientation?; with no answer, the previous orientation comes back after a few seconds. If the screen is unreadable, just wait for this automatic revert.
Slow or choppy photo wall
- Reduce the wall's animations and choose a simpler layout.
- Switch the large screen to Full HD.
- Lower Display performance in Settings › Performance.
See Photo wall display and animations.
