Connecting a computer, laptop or iPad/iPhone to the evidence presentation system.

The court highly recommends that counsel be familiar their equipment and fully test prior to using anything in the courtroom. Please test the audio and video outputs of your equipment at your office or home by connecting to external headphones, monitor or projector if possible, and schedule a visit in the courtroom to test everything before the proceeding.

  1. Connect the provided VGA cable (or HDMI cable where available – see above) to your equipment’s video port. See notes below.
  2. Connect the audio cable plug into the laptop’s headphone jack, which is usually marked with a headset icon. HDMI connections do not need the audio connected separately, as HDMI includes both audio and video.
  3. Turn laptop on last. For VGA courtrooms, your laptop display resolution must be set to 1024 x 768.
  4. The Courtroom Deputy will select your table to test that your laptop is projecting to the court’s monitors properly.

If your laptop display does not appear on the courtroom screens:

  1. Use the laptop keys to toggle the external display – usually by pressing and holding the “Fn” key down, then momentarily pressing the Display Key. The Display Key is usually the F8 or F5 key, or whichever key is marked with “VGA/LCD” or a monitor logo. As you press the Display Key again, most laptops will cycle between displaying on the laptop screen, then the external screen, then both.

    Please note that the display/monitor key may vary by manufacturer, so check your owner’s manual.
  2. Check that the video cable is securely connected to the device’s video output port.
  3. For VGA courtrooms, the screen resolution must be set to 1024 x 768. No other resolution is compatible.

Notes Regarding Video Connectors

As indicated above, for inputs to the system, courtrooms have male connector cables for VGA “DE-15” , or HDMI”Type A”, or both. The court will not provide any additional adapters, cables, etc.Counsel must provide anything additional needed in order to connect their equipment to the court’s systems.

For laptops with only HDMI video outputs, which must connect to courtrooms with VGA only, counsel must provide an HDMI-to-VGA adapter or cable which is compatible with the HDMI port on the counsel’s equipment.

Notes for Apple Devices (MacBook, iMac, iPad, iPhone, iPod, etc.)

Apple devices require an inexpensive and readily available adapter to connect to court systems. Note that iOS devices (iPads, iPhones, iPods, etc.) may not be compatible with the court’s VGA-only courtrooms.

Older iOS devices with 30-pin connectors (iPhone 4, iPad 2 and below) need an Apple 30-pin Digital AV Adapter, such as the ones available from Apple, Amazon and elsewhere.

Newer iOS devices with “Lightning” connectors (iPhone 5 and above, iPad Air and above and iPad Mini) need a Lightning Digital AV Adapter, such as the ones available from Apple, Amazon and elsewhere.

Current MacBooks with USB-C need a USB-C Digital AV Multiport Adapter such as this one from Apple.

Current iMac, MacBook Air and MacBookPro with Thunderbolt 2/Mini DisplayPort need a Mini Display Port to HDMI Adapter, such as this one available from Apple.
