This drives more natural shades and accurate colors, which is useful for pretty much anything, regardless of whether you’re gaming or watching the news, movies, videos, sports, or more. ### 4K upscaling Not all content is made in 4K, and not everyone has a 4K streaming package. So, this feature uses upscaling to bring lower-resolution content up to or near 4K. This makes older content, HD movies, and other media look much better and crisp on a 65″ 4K panel. ### 4K at 120Hz The support for 4K 120Hz is amazing, especially when you consider that it comes with PS5-specific features as well. This is the maximum output of the PS5, meaning you can pair it with the HDMI 2.1 port and push the graphics limits. PSSR can also be used to maintain a stable FPS. Other than that, Auto HDR Tone Mapping and Auto Genre Picture Mode work to automatically optimize the picture depending on what you’re playing or watching. ### Acoustic Surface Audio+ This is one of the coolest features of the A90K. The traditional way of producing sound was to rely on downward- or rear-firing speakers, but this TV does it very differently. Actuators vibrate the OLED panel to produce sound, making it originate directly from the front, providing next-level immersion. ### Voice Zoom 2 This feature is made for action movies as it increases and clarifies the dialogue without raising the main volume. This comes in handy when there is a firefight or explosions in the scene, and the characters are talking. It should also make watching TV at night easier if you don’t want to disturb others. ## More 4K TV deals **Prices and savings subject to change.
