Frequently Asked Questions - ProBeam BU50NST LG

How do I connect the projector to WiFi?

The LG ProBeam BU50NST does not have built-in WiFi. You can use a wired Ethernet connection via the LAN port or attach an external WiFi dongle (USB) if supported by the projector's webOS system.

How do I clean the projector filter?

Turn off the projector and unplug it. Open the filter cover (usually on the side or bottom). Remove the air filter and gently vacuum or wash it with mild soap and water. Let it dry completely before reinstalling. Clean every 3–6 months depending on usage.

Does this projector support 3D playback?

No, the LG ProBeam BU50NST does not support 3D content. It is a standard 4K UHD projector for 2D projection only.

How do I adjust the focus and zoom?

Use the manual lens ring on the front of the projector to adjust focus. For zoom, rotate the second ring. The projector also features automatic keystone correction for vertical and horizontal alignment.

What is the recommended projection distance for a 100-inch screen?

For a 100-inch diagonal 16:9 screen, place the projector approximately 2.5 to 3.0 meters away from the screen. Check the user manual for exact distances depending on zoom.

How do I connect external speakers?

Use the 3.5 mm audio output to connect to powered speakers or an audio system. For digital audio, use the HDMI ARC port (HDMI 3) to send audio back to a soundbar or AVR.

How do I perform a factory reset?

Go to Settings > General > Reset to Initial Settings. Enter the PIN (default 0000) and confirm. This erases all user data and restores to original settings.

What should I do if there is no image?

Check if the lens cap is removed. Ensure the power cable is connected and the projector is turned on. Verify the source input matches your device. If using a laptop, try pressing the function key to enable external display (e.g., Fn+F4).

How long does the laser light source last?

The laser module is rated for 20,000 hours of typical use. At 4 hours per day, that equals about 13.7 years. When it dims, the module must be replaced by a qualified technician.

Can I mount the projector on the ceiling?

Yes, the projector is compatible with ceiling mounts. Use a certified mount that supports at least 15 kg. Ensure proper ventilation and access to ports. Invert the image via Settings > Projector Orientation > Ceiling Mount.

Connecting with a HDBaseT Cable (LAN Cable)

HDBaseT is a connectivity standard that combines digital video and audio as well as various control signals.

HDBaseT signals can be transmitted up to 100 m over a CAT.6 FTP cable.

An HDBaseT TX device allows you to connect multiple sources to the projector via the HDbaseT connection.

- The above connection scenario offers guidance, but the details of an HDBaseT TX device may vary depending on its manufacturer.

NOTE

When Using the HDBaseT

• For more information about how to connect an external device to an HDBaseT TX device (the transmitter), refer to the operator's manual provided with the HDBaseT TX device (the transmitter).
  • To comply with the specifications of the product, use a CAT.6 FTP cable.
• If you do not use a CAT.6 FTP cable, the screen may not display or a connection error may occur.
  • CAT.6 FTP can be used up to 100 m.
  • CAT.5E lower rating is not supported HDBaseT. CAT.5E supports 70 m.
• If HDBaseT cable is used, the cable should not be bent or rolled, it should be straight.
• HDBaseT cables should not touch the power 110 V/220 V cables. It should not be in the water.
• Depending on the HDBaseT transmitting device, the screen of external devices may not be displayed.

The HDBaseT Cable Install

• LAN cables are fairly resilient. Yet, any rough handling, such as tight tie wraps, clamping or stapling can damage the cable, compromising performance or even preventing signal transmission. Tie cables loosely with appropriate cable wraps.
- Another important issue for cable integrity is the bend radius. Bend radius is the inside curve of the cable during and after installation. It is best to keep the minimum bend radius at least at four times the diameter of the cable.
- Cables should be kept at a distance of at least 30 cm from power cables. In an environment prone to high EMI, it is best to use shielded cables.
- If possible, avoid patch cords or cables altogether, as every connection introduces losses in the transmission. If absolutely necessary, make sure to use less than two per cable run and keep each less than five meters from the end.

HDBaseT Recommended cable & transmitting device

Share Computer Content

What Is Content Share?

Content Share allows you to enjoy videos, music and photos saved on your PC.

Play the content with sharing software on the PC

If you have Windows 7 or later installed on your PC, you can play music, video, photos, etc. on your projector without needing to install a separate program.

1 Connect you projector and PC to the same network. PCs installed with Windows 7 or later also need to be connected to a network.
2 Right-click the desired music/video/photo file you wish to play, then select your model using the "Play To" feature built into Windows 7 or later to play the file.
To play on other devices like your mobile phone, refer to the relevant user guide.
- Even when multiple projectors or devices are connected, the selected file is played through only one device. The playback rate may vary depending on the network connection.

Use the SmartShare PC Software to play the content saved on the PC

You can use SmartShare PC Software to connect the music/videos/photos saved on the PC to your home network and play them on your projector.

1 Configure the projector and PC installed with SmartShare on the same network.
- The SmartShare service is only available when the projector and server PC are connected to a single router.
2 Download and install SmartShare PC Software from the LG website (www.lg.com). Before installation, exit all programs running on the PC, such as a firewall or an anti-virus software.
3 Run SmartShare PC Software and configure the share settings.
4 Shared videos and photos are played from the [Photo & Video] app on the projector. Shared music files are played from the [Music] app on the projector.
- The server should be running in order to watch the shared file on your projector.
- For information on how to use the SmartShare PC Software, refer to the software's help section.
