TCL 98Q651G 98"

Manufacturer: TCL

The TCL 98Q651G is a 97.5-inch QLED television built on a LED-backlit LCD panel with a native 4K resolution of 3840 x 2160 px. It supports all four major HDR formats — HDR10, HDR10+, Dolby Vision, and HLG — and runs a built-in smart TV platform with Chromecast, AirPlay, and compatibility with Google Assistant and Alexa. A smartphone can serve as a remote control, and USB recording is available for capturing broadcast content to external storage.

The display delivers 10-bit color depth across over 1 billion colors, 450 nits of typical brightness, a 6000:1 contrast ratio, and 178-degree viewing angles both horizontally and vertically, backed by an anti-reflection coating and an ambient light sensor. Connectivity includes four HDMI 2.1 ports, three USB ports, an RJ45 Ethernet port, Wi-Fi 5, Bluetooth, and Miracast support. Audio is handled by a stereo system rated at 2 x 10W with a built-in subwoofer, supporting Dolby Atmos, DTS:X, Dolby Digital Plus, and both HDMI ARC and eARC for external audio device integration.

Pros

The 97.5-inch QLED panel supports HDR10, HDR10+, Dolby Vision, and HLG, covering all major HDR formats for broad content compatibility
A 6000:1 contrast ratio contributes to well-defined shadow and highlight separation across the large screen area
Four HDMI 2.1 ports and three USB ports provide ample wired source connections without requiring additional switching equipment
An RJ45 Ethernet port allows a stable wired network connection alongside the wireless options
Both HDMI ARC and eARC are included, keeping the path open for lossless audio passthrough to compatible external audio systems
Chromecast and AirPlay are both built in, enabling flexible wireless casting from a wide range of devices

Cons

The built-in audio system is rated at only 2 x 10W, which is modest output for a screen of this size and may push users toward an external sound solution
Wi-Fi tops out at Wi-Fi 5 with no Wi-Fi 6 support, which may limit wireless throughput for high-bandwidth streaming on such a large display
Siri and Apple HomeKit are not supported, limiting smart home integration for users within the Apple ecosystem
There is no external memory slot, so local media playback is restricted to USB-connected storage only
At 56,518 g, the substantial weight makes installation and repositioning particularly demanding and likely requires professional mounting

Who is this for?

The TCL 98Q651G is a natural fit for dedicated home theater rooms where an exceptionally large screen is the centerpiece, as the 97.5-inch QLED panel with a 120Hz refresh rate delivers smooth, immersive visuals across a wide viewing area with 178-degree angles in both directions. Users who maintain multiple connected sources — gaming consoles, media players, and streaming devices simultaneously — will appreciate the four HDMI 2.1 ports and three USB ports, which eliminate the need for external switching. The combination of a wired Ethernet port, Chromecast, AirPlay, and dual voice assistant support via Google Assistant and Alexa also makes it a practical choice for households that want flexible connectivity without compromising on smart home integration.

Who is this NOT for?

The 2 x 10W built-in audio system is notably modest for a nearly 100-inch screen, making this set a poor standalone choice for users who expect the built-in speakers to fill a large room with adequate sound — an external audio solution would be almost necessary in such environments. Users within the Apple HomeKit ecosystem will find the lack of Siri and HomeKit support a genuine limitation for smart home automation workflows. Additionally, at 56,518 g, the sheer weight of this set makes it unsuitable for spaces where flexible repositioning is needed or where professional wall mounting is not a viable option.

Final Verdict

The TCL 98Q651G is a large-format television built for environments where screen presence and HDR versatility are the primary goals — its 97.5-inch QLED panel with a 6000:1 contrast ratio, 120Hz refresh rate, and full HDR format support across Dolby Vision, HDR10+, HDR10, and HLG makes it a technically well-rounded choice for dedicated home theater setups. The four HDMI 2.1 ports, wired Ethernet, and dual casting support via Chromecast and AirPlay add meaningful connectivity flexibility for multi-source arrangements. That said, the modest built-in audio output and the absence of Apple HomeKit support are real considerations for certain users, and the set's considerable weight places practical demands on installation. For viewers committed to a large-screen home theater experience with broad content compatibility and flexible smart platform support, the TCL 98Q651G delivers a cohesive and capable package.
