Pro Good for gaming
While hooked-up with a current-generation gaming console, the Sony X690E offers a smooth and fluid gaming experience thanks to its excellent motion handling capabilities and low input lag.
The motion looks smooth and isn't blurry because of the TV's fast response time. It takes roughly 14 milliseconds for the TV's pixels to change their color which eliminates a lot of the unwanted motion blur effect.
The X690E offers exceptional responsiveness thanks to its low input lag. While in the 'Gaming' mode the TV's input lag drops to roughly 20 milliseconds, which means that you will not feel the delay between pressing a controller's button and seeing the actual thing happening on the screen.
Cons
Con Risk of burn-ins
Just like every other OLED TV present on the market, the F8A can suffer from severe, permanent burn-ins if a static image is left on the screen for an extended period.
Con Can't fight glare
The Sony X690E is not the best TV to place in a bright room with lots of windows because it's not bright enough to fight glare. Its peak brightness is only 250 nits, which is noticeably less compared to what the other TVs in its price range offer.
