Decide depending on the application!
Now we have all the details and it is obvious that the two OLEDs are not that different.
So we can simply say: if you want the gallery design or simply the best OLED for gaming, take the LG G1, the Sony A90J can’t keep up with it and LG is so far really exemplary in terms of gaming updates!
But if you want a TV for your home cinema with the best possible picture and sound quality for gripping blockbusters, then the A90J is the clear choice.
Maybe a quick word about the Playstation 5: It’s not guaranteed, but because it’s from the same manufacturer, you can bet that the A90J will support all the specifications that the Playstation delivers. That means, if the PS5 gets a variable refresh rateHertz is the derived SI-unit of frequency with 1Hz=1/s – When talking about TVs this means how many different pictures a TV can display in one second., then probably also the A90J. Then the A90J would be also gaming-technically, at least as far as this console is concerned, at least on the same level.
But I can’t guarantee that either, unfortunately.
