If your main priority is gaming or watching sports, the Sony X90K is the superior choice, as it excels in these areas with smooth motion and low input lag. Alternatively, if you're interested in the best picture quality for movies and you will be watching in various lighting conditions, the TCL QM8 with its higher overall picture quality and great performance in both dark and bright rooms would be a better fit. Both are similarly priced and support common HDR formats, but the Sony model doesn't offer HDR10+ while the TCL does. Neither of these TVs will deliver sound on par with a dedicated speaker system.

The Sony X90K (LCD) is good for sports, while the TCL QM8 (LCD) is only fair.
The Sony X90K is better for watching sports due to its superior motion processing abilities, which ensure smooth fast-paced action, and its decent performance in well-lit environments because it handles reflections well. However, despite having a fair viewing angle which might limit the view for those sitting off to the side, its response time is still quite competent, while the TCL QM8 offers a fair experience for sports viewing as it doesn't handle motion and reflections as effectively, which could result in blur during fast scenes and difficulty seeing the screen clearly in bright conditions.

The TCL QM8 (LCD) and Sony X90K (LCD) are both very good for cartoons & animation, though the TCL QM8 (LCD) is somewhat better.
The Sony X90K has good performance in displaying vibrant colors straight out of the box and a satisfactory color gamut, making it suitable for cartoons where consistent and accurate colors are crucial. The TCL QM8 also displays colors well immediately without adjustment and has a very good color gamut, ensuring cartoons and animation appear vivid and true to the creators' intent.

The Sony X90K (LCD) is very good for news, talk, & other TV, while the TCL QM8 (LCD) is only fair.
The Sony X90K has better upscaling, making standard definition content look sharper, which is important for news and talk shows, and it manages good brightness levels for SDR content, ensuring clear visibility in various lighting conditions. Whereas, the TCL QM8, while it has superior contrast which helps with color depth, falls short in upscaling and colors out of the box, meaning it won't handle lower-resolution content or initial color settings as well as the Sony.

The TCL QM8 (LCD) is best in class for bright room, while the Sony X90K (LCD) is very good.
The TCL QM8 outperforms the Sony X90K in bright rooms due to its superior SDR and HDR brightness and better handling of reflections, providing a clearer picture in well-lit environments. While the Sony X90K performs very well with an adequate SDR brightness and good reflections handling, the TCL QM8's higher contrast, greater color volume, and color gamut ensure more vibrant and punchy images even in bright conditions.

Al Griffin | December 2022
"As Sony’s next-to-flagship LCD TV, the X90K series delivers impressive performance for the price. The XR90K had fairly accurate out-of-box color. The TV’s multi-position stand lets you either set the screen flush with any stand its mounted on or elevate it to clear space for a soundbar. With the latter option, you get around 3 inches of clearance enough to accommodate most soundbars. The X90K’s excellent suite of gaming features ranks it up there with the best 120 Hz 4K TVs."

About Sony
Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
About TCL
TCL, the highly recognizable TV brand from China, has firmly established itself as the second-largest manufacturer in terms of sales volume. Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package. While they have traditionally excelled in the low-end and midrange TV segments, TCL has recently made remarkable strides in the realm of high-end televisions, introducing impressive models that rival top competitors. Most TCL TVs use Roku software which is very user friendly and easy to use, but they have a few other models that use Google TV which has the largest app selection, but is not as user friendly as Roku.
