Although I do not have an LG TV at this time I hope to buy one soon. Can the SJ8 4.1 Chanel High Resolution Audio Sound Bar woprk with other brands of TV's?

Asked by: gregnj
Depending on what audio connections and features a TV has, the LG 4.1 ch High Resolution Audio Sound Bar, Model # SJ8 will work with any brand of TV provided it has the right connetions and features. If the TV is Bluetooth enabled, you can pair the SJ8 to it and stream audio wirelessly from the TV. Most TVs, it not all nowadays, come with an Optical Digital Audio Output that is used to connect to external receivers, Sound Bars or Home Theater Systems. The SJ8 has an Optical Digital Audio Input that allows for such a connection. It also has an HDMI ARC (HDMI Out) port on it that you can connect to HDMI IN of a TV that supports the HDMI-CEC and ARC function and the HDMI-CEC and ARC must be set to On. The ARC function enables an HDMI capable TV to send the audio stream to HDMI OUT of the unit...^IFV

What're the maximum height, width, and depth after OLED55C7P, SJ8, and T8 TV stand all assembled together?

Asked by: LGBuyer0
The LG T8 OLED TV Mount Stand attaches to the back of the LG C7 OLED 4K HDR Smart TV - 55" Class (54.6" Diag), Model # OLED55C7P in such a way ht of the TV that the main unit of the LG 4.1 ch High Resolution Audio Sound Bar, Model # SJ8 fits snugly under the TV's screen. The height will be the combined height of the Sound bar (1.5") and that of the TV (28.0") for a total height of 29.5". The Sound Bar has a width of 47.64" and the TV has a width of 48.4" so the total width is that of the TV. As for the depth, the Sound Bar has a depth of 4.13" and does add a little depth behind the TV of about 2 inches and with the TV's depth of 1.8" would be a total depth of about 7.93"-8". Regrettably, we do not have the specifications for the depth of the T8 OLED TV Mount Stand to give you an exact measurement for the depth. Please contact our Support Center, (800) 243-0000 to inquire if they may have the specifications for the T8 OLED TV Mount Stand...^IFV
