LG Electronics LG Display Control Spec

Summary

Generic LG TV External Control Device Setup command catalog. Applicability to the cataloged LG Display family is inferred from manufacturer and display class; exact model and firmware support are not stated. Serial 9600/8/N/1 and US-only Telnet/TCP 9761 are described. Features, port variants, 3D, RGB-PC inputs and key availability remain model-dependent. All27 conditional function families are represented; ISM applies only to Plasma models.

Notes

Scope and setup

• Source: generic LG External Control Device Setup, printed pages1–16; exact target models and firmware are not named. Same-manufacturer display applicability is inferred. Every feature, input, port type and key is conditional on the actual model. 3D, RGB-PC and Plasma-only functions are not promised for an LCD/LED target.
• Network IP Control is USA only in this source. On Live TV, hold Settings at least 5 seconds, wait for the banner, enter default828 and OK, then enable Network IP Control in IP Control Setup and accept the reboot. The local three-digit menu password is changeable;828 is not a Telnet session credential. Serial and IP session authentication remain UNRESOLVED.
• Connect via Telnet/TCP 9761 after setup, on wired or wireless network. Source instructs pressing Enter; exact IP command/reply terminator bytes are UNRESOLVED. Do not infer them from serial CR/x framing. Successful IP commands return OK, rejected ones NG. quit closes the session. Blank Enter returning NG can also establish connection.
• Only POWER off is documented over IP. IP power-on uses WOL after enabling Settings > Mobile TV On; this guide does not define WOL packet bytes. There is no documented parameterless POWER query.
• Serial uses9600/8/N/1 ASCII with a crossed cable; flow control is not stated. DE9/phone-jack/USB availability varies by model. USB converter:PL2303, VID0x0557/PID0x2008. USB-to-serial control requires TV on; RS232 cable allows ka while on or off.

Serial framing, data and responses

• Action parameters are transport-specific alternatives: use serial fields only with command, and IP fields only with ip_command. Arrays of IP commands are documented alternative request forms, not a sequence to execute.
• Request [Command1][Command2]<SP>[SetID]<SP>[Data]<CR>;SP=0x20,CR=0x0D. Commands above show \r as an escape for that CR byte, not two literal backslash/r bytes.
• Menu Set ID1..99 is encoded as hex01..63 on the wire;00 broadcasts. Every serial data byte is two ASCII hexadecimal digits. Numeric metadata uses decimal:00..64hex means0..100, and sharpness00..32hex means0..50. IP uses decimal strings for those same numbers. For example volume50 is kf 01 32<CR> vs VOLUME_CONTROL 50.
• Read status with FF for documented readable functions. Feedback query_command arrays are opcode/data tokens; expand them with SetID and framing, e.g.[k,f,FF] means kf {set_id} FF<CR>. No serial ACK or FF read syntax applies to IP.
• Serial OK:[Command2]<SP>[SetID]<SP>OK[Data]x;NG:[Command2]<SP>[SetID]<SP>NG[Data]x. Literal reply terminator x=0x78. Successful writes echo data; reads return status. NG data00=Illegal Code. Tint ACK is j; Treble ACK is r, verified in PDF p8's two columns.
• Multi-byte ma/xt/xv OK replies contain their transmitted data fields; their NG replies contain Data00 only, then x. Serial ma is region-dependent as below.
• During media playback/recording, all functions except Power(ka) and Key(mc) are rejected NG. Lock km blocks IR/local-key power-on in standby; removing/reapplying main power releases lock after20–30seconds. Backlight IP requires Energy Saving off; EQ IP requires Equalizer on.

Regional serial tuning and IP variants

For Europe, Mid-East, Colombia, Asia except South Korea/Japan, serial ma data is channel_hi channel_lo source. Analog channel0..199 (0000..00C7):source00=antenna,80=cable. Digital channel0..9999 (0000..270F):10=DTV antenna,20=antenna radio,40=satellite TV,50=satellite radio,90=cable TV,A0=cable radio.

For South Korea, North/Latin America except Colombia, serial ma data is physical major_hi major_lo minor_hi minor_lo source. Analog antenna physical02..45hex (2..69),source00;analog cable01 or0E..7Dhex (1 or14..125),source01;major/minor are don't-care. Digital major0001..270F (1..9999);minor occupies two bytes but no tighter numeric bound is stated. Digital source02=antenna using physical,06=cable using physical,22=antenna without physical,26=cable without physical,46=cable physical/major only (one-part),66=cable major only (one-part). Populate meaningful fields for the selected variant; don't-care examples use00. The introductory statement calls digital physical unnecessary, but02/06/46 variants explicitly use it; retain the variant distinction.

Japan uses the same six-byte payload. Physical is don't-care;major0001..270F;minor/branch is two bytes and don't-care for satellite. Source02=ISDB-T antenna,07=BS,08=CS1,09=CS2. Do not relabel Japan02 as ATSC. The transmission diagram displays SetID0; all examples use00 broadcast.

Literal source examples, each followed by serial CR:

• Europe analog10:ma 00 00 0a 00.
• Europe digital1:ma 00 00 01 10.
• Satellite1000:ma 00 03 E8 40.
• NTSC cable35:ma 00 23 00 00 00 00 01.
• ATSC30-3:ma 00 00 00 1E 00 03 22.
• Japan17-1:ma 00 00 00 11 00 01 02.
• JapanBS30:ma 00 00 00 1E 00 00 07.

US IP forms are exactly CHANNEL_SETTING_ATSC_ATV {channel} antenna|cable, CHANNEL_SETTING_ATSC_DTV {channel} cablemaj, and CHANNEL_SETTING_ATSC_DTV {major} {minor} antennanotphy|cablenotphy. The pipe notation here means alternatives, not literal wire characters. No other regional IP forms are established.

Equalizer and 3D source limitations

Serial EQ jv packs band-1 into bits7..5 and step into bits4..0. UNRESOLVED source inconsistency: PDF p9 labels the last step 20(decimal), but prints low bits10101 (binary21). Do not treat that last bit-row as an unambiguous serial code. The IP AUDIO_EQUALIZER band 1..5 and step 0..20 ranges are explicit. This is separate from serial-only treble kr and bass ks.

Serial 3D xt sends all four bytes. Mode00=on,01=off,02=3Dto2D,03=2Dto3D;format00..05 and direction00/01 are enumerated above;depth00..14hex is decimal0..20. UNRESOLVED internal conflict: p11 prose says depth has no meaning for mode00, but its relevance table marks it O; prose says direction has no meaning for mode03, while the table marks it O. Another sentence conditions depth for 00/03 on manual3D genre. Mode01/02 marks all remaining bytes don't-care. Keep all four bytes and do not claim a resolved relevance/default rule. IP syntax is explicit and requires all shown arguments for on and2dto3d.

Extended 3D serial xv:

• Option00 picture correction:00=right-to-left,01=left-to-right.
• Options01 depth/02 viewpoint:00..14hex (0..20);viewpoint maps to-10..+10, model-dependent. Source requires manual genre for these serial options.
• Options06 color correction/07 sound zoom:00=off,01=on.
• Option08 normal view:00=revert to3D from3Dto2D;01=convert3D to2D except2Dto3D video;invalid conversion state returns NG.
• Option09 genre:00=Standard,01=Sport,02=Cinema,03=Extreme,04=Manual,05=Auto.

Extended 3D IP:

• picturecorrection0/1=right-to-left/left-to-right;requires PICTURE_3D on ....
• colorcorrection,sound,normal0/1=off/on per IP table;each requires PICTURE_3D on .... Do not borrow serial option08's phrasing as a different IP boolean mapping.
• depth0..20 requires PICTURE_3D 2dto3d ... then PICTURE_3D_EXTENSION genre 4.
• viewpoint0..20 requires PICTURE_3D 2dto3d ...;the IP table does not also require genre4 here, unlike the serial prose.
• genre0..5 uses Standard,Sport,Cinema,Extreme,Manual,Auto and requires PICTURE_3D 2dto3d ....
