Product Snapshot

Overview

First released back in early 2022, the Sony A90K OLED TV is a high-end 4K HDR model that, as the name suggests, sports an OLED panel for perfectly deep blacks and infinity contrast.

It also boasts a total of four HDMI ports, two of which support the full HDMI 2.1 48 Gbps bandwidth to support the PS5 and the Xbox Series, similar to the best TVs in its range.

And it also features one USB 3.0 port, an optical audio jack, and an ethernet port. If you need all four ports to be HDMI 2.1, check our LG G2 OLED TV review.

The Sony A90K OLED TV supports both HDR 10 and Dolby Vision formats. And it features a native 120 Hz screen with VRR that can function down to 20 Hz. But if you need a brighter OLED TV, check our Sony A95K OLED TV review.

Consensus

our Verdict

The Sony A90K OLED TV is a great option for those looking for a high-end TV to use as a bedroom TV or a desktop monitor, as it features a fairly high peak brightness which was tested at 682 nits.

It also has four HDMI ports, two of which support HDMI 2.1. And thanks to its OLED panel with an infinite tested contrast ratio, it can display perfectly deep blacks.

It also sports a semi-gloss matte panel for glare. It has a fast measured response time of 0.3 ms. If you are looking for an outdoor TV, check our SunBriteTV Veranda TV 3 4K Android review.

The Sony A90K OLED TV also boasts a superb upscaling chip for low-res content. But it doesn’t support AMD FreeSync or GSync.

Reason to Buy

  • Excellent picture quality
    • Ideal for TV shows, immersive movies, and casual gaming, this versatile TV boasts vibrant colors with its remarkable color gamut that covers 98.97% on DCI P3 xy. Watching dark scenes is outstanding, too, thanks to its perfect black uniformity (std. deviation of 0.286%).

  • High contrast ratio
    • The TV delivers excellent accuracy for nighttime viewing due to its near-infinite tested contrast ratio, which is among the highest we’ve seen.

  • Low-tested response time and input lag
    • Content appears ultra-smooth thanks to the fast measured 0.3 ms response time, and although the tested 17.5 ms (4K at 60 Hz) input lag is among the bottom third of our tested TVs, it’ll be sufficient for casual gamers.

  • Fast refresh rate and VRR support
    • At 120 Hz, you’ll enjoy lag-free visuals for smooth gaming, and there is no screen tearing with VRR support.

  • Wide viewing angles
    • Visuals remain consistent even when you move far from the center, with colors washing out at 58°, which is ideal for wide seating arrangements.

Reason to Avoid

  • Limited HDR peak brightness
    • Although the peak brightness reaches 626 nits, which is average compared to the other tested TVs, it frequently fluctuates from scene to scene and isn’t suitable for well-lit spaces.

First released back in early 2022, the Sony A90K OLED TV is a high-end 4K HDR model that, as the name suggests, sports an OLED panel for perfectly deep blacks and infinity contrast.

It also boasts a total of four HDMI ports, two of which support the full HDMI 2.1 48 Gbps bandwidth to support the PS5 and the Xbox Series, similar to the best TVs in its range.

And it also features one USB 3.0 port, an optical audio jack, and an ethernet port. If you need all four ports to be HDMI 2.1, check our LG G2 OLED TV review.

The Sony A90K OLED TV supports both HDR 10 and Dolby Vision formats. And it features a native 120 Hz screen with VRR that can function down to 20 Hz. But if you need a brighter OLED TV, check our Sony A95K OLED TV review.

While the Sony A90K OLED TV only comes with 48 and 42-inch OLED panel sizes, the Sony A80K OLED TV features significantly larger 55, 65, and 77-inch screen sizes. On the other hand, the Sony A80K OLED TV suffers from a visible black crush in compressed streamed video content, but the Sony A90K OLED TV does not, thanks to its smaller screen size. And its smaller screen size also allows the Sony A90K OLED TV to better fit in most setups and be used as a desktop monitor than the larger Sony A80K OLED TV. Make sure to take a look at our Sony A80K OLED TV review if you want to learn more about the compared model.

Even though both the Sony A90K OLED TV and the LG C2 OLED TV feature HDMI 2.1 support, the Sony A90K OLED TV only supports the full HDMI 2.1 48 Gbps bandwidth through two of its four HDMI ports, whereas the LG C2 OLED TV supports the full HDMI 2.1 48 Gbps bandwidth through all four of its HDMI ports. And the LG C2 OLED TV has native AMD FreeSync support with GSync compatibility, which the Sony A90K OLED TV completely lacks. The LG C2 can also display 1440p at 120 Hz, which the A90K lacks.

The Sony A9S TV is the direct predecessor to the Sony A90K OLED TV, and they both feature a similarly specced OLED panel and perform very similarly overall. However, as an advantage of being newer in the market, the Sony A90K OLED TV comes with HDMI 2.1 ports to better support the current-gen gaming consoles, while the Sony A9S TV is still limited to the older HDMI 2.0 standard. As a result, the Sony A90K OLED TV also supports a variable refresh rate down to 20 Hz, but the older Sony A9S TV unit does not.

The Sony A90K OLED TV features a higher peak brightness of 682 nits in comparison to the LG C1 OLED TV’s 432 nits of peak brightness. And it works with LG’s WebOS user interface, while the Sony A90K OLED TV runs on the Google TV UI. The LG C1 OLED TV also features the brand’s much-coveted magic remote with Wiimote-like motion controls, while the Sony A90K OLED TV’s metallic remote lacks motion controls. However, the LG C1 OLED TV’s HDMI 2.1 bandwidth is limited to 40 Gbps, unlike A90K.
