Nie, dziękuję Przekieruj mnie tamDoes product code 37LD450 have bluetooth
• No. The LG TV with product code 37LD450 (37-inch, 2010-era LD450 series) was not equipped with a Bluetooth radio and therefore offers no native Bluetooth functionality.
• Only hard-wired A/V interfaces (HDMI, component/composite, D-Sub PC, optical S/PDIF, 3.5 mm headphone, RS-232C, USB for media/service) are provided.
Product positioning and release window
• The LD450 line was LG’s entry–mid class Full-HD LCD range for model year 2010.
• That generation pre-dated widespread adoption of wireless audio interfaces in mainstream televisions.
• Official LG spec sheets (e.g., document “LG_HE_LCD_SS_37LD450-4.pdf”) list no Bluetooth nor Wi-Fi chipset; service manuals confirm the main board (EBT610561xx) lacks any RF module.
Connectivity breakdown
Outputs/inputs on the rear & side panels:
• 3× HDMI 1.3
• 1× Component (YPbPr) / Composite shared
• 1× D-Sub (RGB) + 3.5 mm PC audio in
• 1× Digital optical audio out (TOSLINK, fixed level)
• 1× 3.5 mm headphone out (variable level, mutes internal speakers)
• 1× RS-232C (service/control)
• 1× USB 2.0 (JPEG/MP3 video still/firmware)
‑- No wireless radios, no antenna diversity, no Bluetooth stack in firmware.
Firmware/UI check
• The on-screen menus contain no “Sound → Bluetooth” or “Connection → Device List” items found in later WebOS sets.
• Service mode (INSTOP + OK) also shows no BT option flags.
Implication
• Bluetooth headphones, soundbars, gamepads, or mobile casting cannot be paired directly.
• Any wireless function must be added externally (see Practical guidelines).
• By 2016–17 LG began adding Bluetooth (V4.0/4.2) to mid-tier IPS LCD and all OLED lines for headphone audio and Magic-Remote pairing; today (2023-24) virtually all LG WebOS models ship with BT5.x, LE-Audio imminently.
• For legacy sets like the 37LD450, aftermarket low-latency transmitters (aptX LL, LC3, LE-Audio) remain the de-facto upgrade path.
• HDMI-ARC Bluetooth bridges and eARC dongles are gaining traction but require ARC support, which the LD450 lacks; optical or 3.5 mm remains the route here.
Latency: Standard SBC codec ≈ 180 ms; aptX LL ≈ 40 ms → lip-sync acceptable for video.
Audio quality: Optical connection delivers bit-perfect PCM, avoids headphone-jack noise floor and volume auto-mute.
Power: The LD450’s USB port sources 5 V / 500 mA max; adequate for most transmitters (<120 mA).
• Observe regional RF regulations (FCC Part 15 / ETSI EN 300 328) when using external 2.4 GHz devices.
• If connecting to assistive-listening headphones in public venues, ensure compliance with accessibility policies.
• Copyright: transmitting TV audio via Bluetooth in commercial premises may constitute public performance—obtain proper licenses.
Hardware selection
• Choose a dual-input (optical & 3.5 mm) Bluetooth 5.0/5.2 transmitter supporting aptX Low-Latency or LC3/LE-Audio.
• Look for “dual-link” if two headsets will be used.
Optical method (recommended)
a. Cable: TOSLINK → transmitter.
b. TV menu: Audio → Speaker Select → “External Speaker (Optical)” → Digital Audio Out Format → “PCM”.
c. Pair headphones → verify lip-sync.
Headphone-jack method (simpler, lower cost)
a. 3.5 mm TRS → transmitter.
b. Note: Inserting the plug mutes TV speakers; use headphones’ volume control.
Troubleshooting
• No audio: Check PCM output, optical cable seating (plastic dust caps removed).
• Lip-sync: Ensure both ends support aptX-LL/LC3; else switch to analog jack (variable delay).
• Dropouts: Power transmitter from wall adapter, not TV USB, to avoid current-limit resets.
• While every 37LD450 ever shipped lacks Bluetooth, LG occasionally re-uses chassis numbers for hotel/health-care variants (e.g., 37LD452C). Always cross-check the exact label on the rear cover.
• Firmware updates cannot enable Bluetooth; the radio hardware is absent.
• Evaluate LE-Audio transmitters (Auracast) for multi-listener scenarios.
• Monitor HDMI eARC Bluetooth bridges as potential one-cable upgrades for other legacy TVs.
• Review ITU-T G.1030 & ETSI TS 103 769 guidelines on latency perception for future codec choices.
The LG 37LD450 television does not incorporate Bluetooth hardware or firmware support. To enjoy wireless audio you will need an external Bluetooth transmitter connected via the set’s optical S/PDIF or 3.5 mm headphone jack. Select a modern, low-latency transmitter, configure the TV’s audio output to PCM, and pair your headphones or speakers accordingly.
