TCL 98Q651G 98-Inch QLED 4K Smart TV: what it is
The 98Q651G is the 98-inch model in TCL’s Q6 series for 2024, first listed in May of that year. It is a quantum dot LCD television running Google TV. The listing records a 98-inch standing screen display size, a 16:9 aspect ratio, a weight of 120.15 pounds, product dimensions of 2.81 by 85.79 by 49.09 inches, Mexico as the country of origin, and a special features list naming a built in speaker, Game Mode, Chromecast, a wide color enhancer and a bezel-less design. TCL’s own description adds quantum dot technology, HDR Pro Plus with Dolby Vision, a High Brightness Plus direct LED backlight, the AIPQ processor, Game Accelerator, Auto Game Mode, Dolby Atmos, DTS Virtual X and an enhanced dialogue mode.
Ninety eight inches is a room defining purchase. Plan for a viewing distance of twelve to sixteen feet, a wall that can take 86 inches of width, and a delivery route through the house that a carton of that size will physically pass through. At 120 pounds this needs three people and a properly engineered mount, rated well beyond the 84 inch and 100 pound ceiling of a mainstream model such as the Mounting Dream MD2296.
Backlight and motion, described accurately
TCL names a High Brightness Plus direct LED backlight. Direct LED means the LEDs sit behind the panel rather than along an edge, which is a structural advantage over edge lighting. It is not mini-LED, and the listing does not name mini-LED, local dimming or a dimming zone count anywhere. A set that does name those things, such as the Hisense 85U6N Mini-LED, controls contrast differently, and anyone cross shopping at this size should understand that the two are not equivalent.
On motion, TCL’s description cites “Motion Rate 240 with MEMC frame insertion”. That figure needs handling carefully, because it is exactly the kind of number this catalog exists to explain. Motion Rate is a processed marketing figure, not the panel’s refresh rate. MEMC stands for motion estimation and motion compensation, which is frame interpolation: the processor invents intermediate frames between the real ones to smooth movement. It is the effect many viewers know as the soap opera look, and it can be turned off. The native panel refresh rate is not published anywhere in this listing. Anyone buying with gaming in mind should get that figure in plain hertz from TCL.
The description also mentions “Game Accelerator 120” with an asterisk, and the asterisk is never explained in the listing text. On televisions generally, a high frame rate game mode at a stated number often applies only at reduced resolution. Confirm what resolution the 120 figure applies to before buying on the strength of it.
HDR and color
HDR Pro Plus with Dolby Vision is named, along with quantum dot color and a wide color enhancer. Dolby Vision is dynamic metadata HDR and its presence is worth having. What is missing again is a peak brightness figure in nits, without which the HDR support is format compatibility rather than a performance level. No contrast ratio is published and none is invented here.
Sound and platform
The audio package is unusually complete on paper: Dolby Atmos, DTS Virtual X and an enhanced dialogue mode. Dialogue enhancement is a genuinely useful feature on a large panel, where thin cabinet speakers routinely lose speech under music and effects. Atmos through built in drivers remains processing rather than true height reproduction, and on a screen this size a soundbar or receiver is close to mandatory.
Google TV is the platform, with Chromecast built in and Alexa compatibility named in the manufacturer title. App availability on any smart platform is set by the streaming services rather than by TCL and changes over time.
Highlights
- 98-inch 4K quantum dot LCD panel, a genuine alternative to a projector in a large room.
- Direct LED backlighting rather than edge lighting, with TCL’s High Brightness Plus label.
- HDR Pro Plus with Dolby Vision, plus the AIPQ picture processor.
- Dolby Atmos, DTS Virtual X and an enhanced dialogue mode.
- Google TV with Chromecast built in and a voice remote.
- 2.81 inch panel depth, remarkably slim for a screen this size.
- 2,102 customer ratings on record averaging 4.3 stars, a large feedback base for a 2024 model.
Things To Consider
The published specification stops short in three places that matter: no native refresh rate, no peak brightness figure and no local dimming zone count. The features that are named are largely processing labels rather than panel hardware figures, and TCL’s description leans hard on superlative marketing language that no listing data supports. Where a claim is unsupported here, it has been left out rather than repeated.
Installation is the practical barrier. A 120 pound panel that is 85.79 inches wide will not go up the stairs of many homes. Measure the delivery path, the doorways and the wall, and budget for professional installation if there is any doubt.
No voltage or wattage figure is recorded on this listing. A screen this size draws real power, and anyone planning a recessed outlet behind a wall mount should confirm the requirement with TCL.
The direct LED backlight without local dimming means dark scenes will show raised black levels and the whole panel will brighten and darken together rather than in regions. On a screen this large that is more visible than it would be on a small one.
Who should buy it, and who should not
This suits a large basement, a games room or an open plan living space where the wall exists, the seating is genuinely twelve feet back or more, and the buyer wants maximum screen area for the money. The strong rating base across 2,102 reviewers is meaningful reassurance for a product at this size and price.
Skip it if the room is not big enough, which is the most common mistake at this size. Skip it if dark room contrast is the priority, where an OLED such as the Sony BRAVIA XR A80L is a different class of picture and the OLED TVs category is the place to compare. And skip it if a confirmed high refresh panel matters, in which case the Hisense 100QD7N publishes a native 144 hertz figure at a comparable size. The wider range sits in the QLED TVs category.
