  • Brilliant quality and thinnest TV I have ever seen
    Reviewed by Sakn - August 5, 2021

    I bought this TV a month ago for my new flat and brightened up my living room and for my well-being as well. The TV is visibly so pretty as it is very thin and the screen looks sophisticated.The screen quality is great for watching movies or general live TV. There are lots of apps I can download which means that I can watch YouTube or Netflix or Disney+ at any time that I want. The delivery was quick and it was easy to set up after reading the guide provided by LG. The smart remote control is very useful and great at recognising my voice as well which makes it easy to navigate the TV. All my friends who have visited have commented on the TV on its quality and sound and its design!

  • Amazing TV!
    Reviewed by Sushiebeauty - March 10, 2022

    This TV is a game changer for anyone who is serious about leveling up their TV game! Firstly, read the quick installation manual before taking the TV out of the box. The 65 inch TV requires two people and it's super thin (unbelievably thin, thickness is comparable to a cheese slice). It does have some weight to it, so best to lay it down flat on the couch with the bottom of the TV sticking out, this will enable you to screw the legs on (have a screw driver on hand). It's so thin, it would absolutely look amazing wall mounted too! Screwing the legs on was really the "hardest" part of installing the TV. After that, sit back and wait for the apps to install and update. Enjoy! The LG A1 Oled series is the "entry" level oled TV, and you get value for money features. The millions of self-lit pixels all do what they are meant to do, which is to produce the deep blacks and sharp, vivid colours! Me and hubby would just sometimes marvel at how magnificent the pictures all look on this TV! The low blue light and flicker-free feature (for eye comfort display) is definitely a bonus because I do worry about the effects of TV on my kid's eyes. The home menu screen has so many different apps, which doesn't bother me and I love the variety. But I do wish they offer a simplified version as well for the not-so-tech-savy people, like my parents. The stand out feature that I love is the LG art gallery, which shows a different artwork every 5 seconds. Why go to the gallery when LG will bring the gallery to you? The AI picture and sound, which automatically adjust to whatever your watching is so clever! I am such a huge fan of LG (amazing quality and brand reputation), and this TV did not disappoint! #complimentary #lgaustraliaxinfluenster

  • Love love love it !!
    Reviewed by Anonymous reviewer - December 8, 2021

    [This review was collected as part of a promotion.] We absolutely love this tv ! It was so easy to set up took seconds , we also had a professional install it as it is thin we was worried we would be too heavy handed for it . Looks great on the wall out of the kids reach ! The picture and sound quality is amazing we didn’t expect it to be this good but it exceeded our expectations. We are not really “techy” but we have told everyone about our new tv . It’s so quick and easy to use and I use the voice button all the time to change between apps . I’m sure there’s still more I haven’t discovered yet ? It’s like a computer , you can view google , Facebook on there too.

  • Amazing quality picture ❤️
    Verified BuyerReviewed by Love - September 12, 2021

    The picture is beyond words, and the Geek Squad were knowledgeable, patient and very professional. They showed me what it could do, and I am not computer savoy. Thank goodness my daughter was here and totally understood what they were talking about. I couldn’t be happier with the product, the installation or Best Buy service. I will always buy there 1st from now on.

  • Super thin and huge screen
    Reviewed by zszilag - January 20, 2022

    [This review was collected as part of a promotion.] After a terrible experience with the supplier and months of waiting to get this TV shipped to me, I have to say I really had low expectations but it turned out to be a great TV. It is very big and impressive, it is super thin, really just like a glass panel, so the design is really impressive. It has great picture and sound quality and it was very easy to set up for the first time. I really enjoy that I can connect any device to it and continue watching something I started on my laptop or on my phone. It is also easy to use browsers, streaming services, and other apps on it, although using the remote as a mouse took me some getting used to. Sometimes some apps take a while to load which I guess could be improved but other than that I had no negative experience with it so far. The only thing I would criticize is its very low energy rating (G) which is surprising for such an innovative and new TV, and I would expect the manufacturer to pay more attention to sustainability.
