What You Need

• TV box (powered and working)
• Mini projector
• HDMI cable
  • If your projector has mini-HDMI or micro-HDMI, use the right adapter or cable
• Power adapters for both devices
• Optional: external speaker or soundbar (3.5 mm or Bluetooth)

Step 1: Check the Ports

1. Look at the TV box. Find the port labeled HDMI OUT.
2. Look at the projector. Find HDMI IN (HDMI1/HDMI2).
3. If the projector only has VGA/AV, you will need an HDMI-to-VGA/AV converter (powered).

Step 2: Place and Power

1. Put the projector on a flat surface, facing the screen or wall.
2. Leave space for air vents.
3. Plug in the projector and the TV box to power.

Step 3: Make the HDMI Connection

1. Plug one end of the HDMI cable into the TV box (HDMI OUT).
2. Plug the other end into the projector (HDMI IN).
3. If your projector has mini/micro-HDMI, attach the adapter, then connect.

Tip: Do not use a projector USB port for video. Most USB ports on projectors give power or read files only.

Step 4: Select the Correct Input

1. Turn on the projector.
2. Press Source/Input on the projector remote.
3. Choose HDMI (HDMI1 or HDMI2).
4. Turn on the TV box. You should see the TV box home screen.

Step 5: Set the Right Picture Size

1. Use the focus ring on the projector until the image looks sharp.
2. Use keystone controls to fix a tilted picture.
3. Move the projector forward or backward to adjust image size.

Step 6: Match the Resolution (Important for Clear Picture)

1. On the TV box: Settings → Display/Screen → Resolution.
2. Choose a resolution your projector supports (often 1080p 60 Hz or 720p 60 Hz).
3. If the screen blinks or says “Out of Range,” choose a lower resolution.

Step 7: Get Sound Working

You have three choices:

1. Use projector speakers: sound comes through HDMI automatically.
2. Use an external speaker from the projector: plug a 3.5 mm cable into the projector’s Audio Out, or pair a Bluetooth speaker to the projector (if supported).
3. Use an external speaker from the TV box: plug a 3.5 mm cable into the TV box (if it has one) or pair a Bluetooth speaker to the TV box.

Tip: In TV box Audio settings, select Stereo if you hear no sound.

Step 8: Test with an App

1. Open YouTube (or any app) on the TV box.
2. Play a video and check picture, sound, and smooth playback.
3. Adjust volume on the projector, speaker, and TV box if needed.

Optional: Wireless Ways (If You Don’t Want a Cable)

• Wireless HDMI kit: Plug the transmitter into the TV box HDMI, and the receiver into the projector HDMI. Power both with USB. This sends video wirelessly.
• Streaming stick directly to projector: You can plug a Fire TV / Roku / Chromecast into the projector’s HDMI and skip the TV box. This is another option if your goal is streaming.

Quick Troubleshooting

• “No Signal” on projector: Wrong input selected, loose HDMI cable, or bad adapter. Re-seat the cable and choose the correct HDMI input.
• Image but no sound: Check Audio settings on the TV box (set to Stereo), try projector volume, or use a 3.5 mm speaker.
• Flicker or black screen: Use a shorter/better HDMI cable, set 1080p or 720p at 60 Hz.
• USB won’t show video: USB on projectors is usually for power or media files, not HDMI video.
• Lag or stutter: Switch apps to lower quality (e.g., 720p), improve Wi-Fi, or use Ethernet on the TV box.
