Great value for the price!

After one month of use we are very pleased with this OLED TV. We had to tweak the settings for display and sound and enjoy quality of presentation. The only minus: the remote is too crowded and not really easy to use in the dark. Maybe our hands are too big!

Brilliant TV

Took a huge leap by going for a 77inch one, rather than a 75 inch. It's huge!! Sound - this is much better than I was expecting and you don't need a soundbar unless you want full surround sound with rear speakers. TV screen quality. It has a thing called Filmmaker mode for watching movies which is fantastic. It's exactly like being in the cinema. Screen glare and reflection - on a sunny day you do get a bit of reflection, but it's not a big deal, just shut your curtains. Ease of use. The remote is huge and has an annoying cursor which flies around the screen. Apart from that it is easy to setup The operating system. For a TV as expensive as this, one would have expected everything to be super quick, but it can be quite slow at times. This is true of all lg TVs using the webos system, but it's not a deal breaker. Summary. This is an excellent TV, which I bought at a substantial discount. Highly recommend. So much so that when I wanted a TV for my bedroom I went for another LG TV. I also found the LG website very useful too.
