Rated 5 out of 5 by from A whole new level Awesome thin panel it looks amazing.Its thinner than a pen too

Rated 5 out of 5 by from Wow! Wow!. That was the word I will choose for the display and audio on this tv. First of all I read multiple mixed reviews from the previous owners and have 50% fear until I experienced this product. Lg shipped it fast in about 2 days :) . I unboxed it and installation instructions looked straight forward, but there was a bit of hassle in installation at my home with nails in wall :( . when i switched on it lg software updated and took some easy initial steps but thats not it I choose to write this review because of the video and audio quality of the picture. Lg did a very good job in preserving each pixel in that picture and dolby experience is breathtaking with surround switched on. I havent seen any pixel blurring like many reviews posted even in high 4k settings. There are some areas of improvement needed with providing inbuilt google chromecast for this model. I think lg soved that in w9. I have never used miracast before so it was kind of an exploration for me and all the miracast apps are purchase/subscription only. Webos under lg is improving a lot. As a programmer myself I Can see how good the new webos update is. I heard the dolby experience is managed by software rather that the audio speaker below(how did they do that?!!!) . Lastly, when ever I switched on tv there was a cool cinema theatre sound and the way speakers coming from sound bar is just awesome.

about to purchase this tv and with it the LHB675 sound system, is this system better and louder than the stock tv sound bar, also can the LG CJ98 be hooked up to this tv somehow and if so which of these 3 speaker setups is the best,loudest, power etc

Asked by: derickshay
Thank you for your interest in the LG SIGNATURE OLED TV W - 4K HDR Smart TV - 77" Class (76.7" Diag), Model # OLED77G7P and for considering it. The "stock TV Sound Bar" on the TV is a 4.2 Channel System that has an Output Power of 60W. As you can see from its title description, the LG 3D-Capable 1000W 4.2ch Blu-ray Disc™ Home Theater System, Model # LHB675 is also a 4.2 Channel unit, but the difference being that this is a Home Theater System and it has an Output Power of 1000W, so it will be louder since it has much more power. The LG 3500W Hi-Fi Entertainment System with Bluetooth® Connectivity, Model # CJ98 can be paired to the TV via Bluetooth for a wireless connection and with an Output Power of 1180W x 2 for its front speakers and 570W x 2 for the Subwoofers in each speaker (total output of 3500W), it will be the loudest of the three. As for which one is the best, that will depend on the room that you have it installed in, or how close you will be sitting to the TV. The height of your ceilings, whether you have drapes or not and whther your floors are bare or carpeted will all have an impact on the Sound...^IFV
