Both the TCL QM8 and Samsung QN90C deliver sleek, modern designs, but they take different approaches. The QM8 has a minimalist aesthetic with a slim metal bezel and an angled center-mounted stand, ensuring it fits seamlessly into any living room setup. Its 98-inch model—the first from TCL with mini-LED technology—features feet mounted at either side to support its massive size. While the included remote control feels intuitive, its thin, long design with direct Netflix, Prime Video, and Apple TV Plus buttons offers a comfortable user experience, enhanced by a built-in microphone for voice commands.

On the other hand, Samsung’s QN90C comes with a NeoSlim design that exudes sophistication with an aluminum finish and a more compact hexagonal stand. Its remote is smaller and features non-backlit buttons but compensates by being highly functional, especially with built-in voice command activation. The overall design is meant to make the QN90C a stylish addition to modern homes, offering a refined touch of minimalism with practicality in mind.

#2 Image Quality

When it comes to picture performance, both models shine, but in different ways. The TCL QM8 boasts QLED technology enhanced by mini-LED backlighting, featuring an astonishing 2,321 nits of peak brightness (with reports suggesting up to 5,000 nits). Its 1080 local dimming zones on the 65-inch model create deep blacks with minimal blooming, ensuring that even high-contrast scenes remain clear and vibrant. Its support for Dolby Vision IQ, HDR10+, HDR10, and HLG makes it a versatile set for HDR content, offering a dynamic and immersive viewing experience.

Meanwhile, Samsung’s QN90C holds its own with impressive brightness levels, peaking at 1,787 nits in Movie mode and maintaining excellent contrast with its mini-LED backlighting. Although its Delta E values hover in the 3-4 range, the accuracy of skin tones and rich color saturation make it an ideal option for film enthusiasts. One key difference is the QN90C’s lack of Dolby Vision, but its Neo Quantum HDR+ does provide dynamic processing for a wide range of HDR content, including HDR10+ and HLG.

#3 Sound Quality

The TCL QM8 brings an adequate sound profile for a TV in its class, featuring a 2 x 10-watt speaker system plus a 20-watt subwoofer. While its default Standard setting may seem crisp, the dialogue clarity shines through, and modes like Movie Mode kick up the bass for a richer experience. With Dolby Atmos and DTS Virtual support, it ensures that soundtracks and movies benefit from spacious, enveloping audio.

In comparison, Samsung’s QN90C takes sound performance up a notch with a 4.2.2-channel Dolby Atmos setup, creating a broader soundstage through its Object Tracking Sound Plus technology. While the bass doesn’t have the same punch, the TV compensates with its Q-Symphony 3.0 feature, designed to sync with Samsung soundbars for a fuller home theater experience. Although high volumes can lead to some compression, the Amplify setting helps in keeping the sound both loud and clear.

#4 Smart Features

Both TVs excel in smart features, but with different operating systems at the helm. The TCL QM8 uses Google TV, offering over 800 free-to-stream channels in addition to customizable profiles, intuitive navigation, and voice command integration via Google Assistant. Gamers will appreciate the dual HDMI 2.1 ports that support 4K 120Hz input and up to 144Hz for gaming via HDMI input 1. With Game Accelerator allowing up to 240Hz VRR gaming at 1080p, this TV caters well to those seeking low input lag and smooth frame rates.

Samsung's QN90C, powered by the Tizen interface, delivers a similar experience with a streamlined UI and support for voice commands via Bixby, Alexa, and Google Assistant. Its standout feature is the Samsung Gaming Hub, which consolidates cloud-based services like Xbox, Nvidia GeForce Now, and Amazon Luna. With support for VRR, FreeSync Premium, and a mere 9.8ms input lag, the QN90C holds a slight edge for serious gamers looking for optimal performance.

#5 Connectivity

Connectivity is another area where these two models match up closely. The TCL QM8 offers four HDMI ports, including two HDMI 2.1 ports that allow 4K 120Hz input, along with eARC support for enhanced audio. It supports Bluetooth audio output and integrates seamlessly with Google Assistant, Alexa, and Apple HomeKit. AirPlay 2 and Chromecast are also built in, giving users a wide range of options for content casting.

On the other side, Samsung’s QN90C also features four HDMI 2.1 ports, but it has an added advantage with ATSC 3.0 support, making it future-proof for next-gen digital broadcasts. It too supports voice assistants and features a built-in tuner for OTA channels. Its connectivity options are rounded out by Samsung SmartThings, allowing users to control smart home devices directly from the TV screen, making it a hub for home automation.
