    This review is about the size: 50 "

    LG image quality, no issues or complaints so far. The size was borderline for a bedroom (max 4m distance) but it doesn't tire you in the end. Also, the sound is impressively good.

    This review is about the size: 65 "

    Unfortunately, my experience with this particular LG is not good. The menu lags quite a bit, which becomes annoying in daily use; I clearly expected better performance. Additionally, it shows some white "burns" around the edges of the screen, which ruin the image.

    It doesn't have a nice or convenient control and there is some issue when opening the YouTube app. It doesn't always work perfectly. I expected better performance from such a television.

    This review is about a variation of the product

    Very good but it has a cumbersome remote control, when you turn it on it goes straight to a general menu and you have to find a button to press to go to tv live, which button should have been given a color and placed in a position where you can easily find it. These, of course, are details; otherwise, whoever wants to get involved has a lot to explore, it has a nice picture, nice sound, what more do you want?

    This review is about a variation of the product

    both myself and my other housemates are very satisfied
    unfortunately I didn't have much experience, mostly with computers
    but linux is OK!
    maybe other models have more features
    but the lack of English knowledge among my housemates, along with a bit of myopia/presbyopia when using the remote control, makes things difficult for very modern features, beyond the price criterion...
    thank you very much (from the whole family & for the prompt delivery)

    This review is about the size: 65 "

    I am loving the blacks, side views, everything.
    Sound is pretty decent, the only negative is LG OS, which sucks so bad, if you are an iptv user, the app refreshes itself after 20 minutes, restarting the whole.

    Doesn’t do that on Netflix or Prime though.

    This review is about a variation of the product

    It is a cheap TV that does everything to a satisfactory degree for its price, of course. Good picture quality with average to poor blacks, menu relatively cumbersome but fast, good build quality and the sound is better than expected. Compared to the OLED in the living room, the comparison is laughable, but so is its price at €250, which is what I paid. Value for money TV and I don't regret it.
