Innovative Minds Worldwide to Step Forward with Ideas for People and the Planet Multinational Tech Company’s USD 1 Million Innovation Challenge Invites I have attached a short video showing the TV connected to chromecast and the display working as expected and then pressing the settings button yields artifacts/small black squares. I have also carried out a factory reset and this has not made a difference. The other two gives no output when a device is connected. I've attempted to reflash it and downgrade it but I haven't managed to find a way to do it.Īlso note that only 1 of the 3 HDMI ports work. The TV has the latest software update running (04.06.25). I suspect this could be either a software issue since there's no physical defects with the display itself. However, the TV works flawlessly when using the display with a HDMI device connected. The issue: On the LG menu and main home screen + sub menus and programs such as Netflix, there are black squares all over the display which makes it impossible to use. Hi all, I have this 4K LG 49UF772V TV which has had this issue since I bought it second hand and I'm wondering if anyone has any idea how it can be fixed as I am looking to sell it.
