TCL 98A400 98-Inch QLED TV: Full Review for Home Theater and Gamers
TVsAt a Glance
The essential numbers and the honest summary before going deeper
Editor's Score
Based on full specification review
At nearly eight and a half feet wide, the TCL 98A400 stops being a television and starts being an architectural feature. Four full-bandwidth HDMI 2.1 ports, 144Hz at 4K, and complete HDR format coverage place it among the most capable large-format displays at this price tier. The trade-offs — moderate peak brightness and modest built-in audio — are real, but entirely manageable with the right room and the right setup.
Build Quality and Physical Presence
What 98 inches actually looks and feels like installed in your home
Size in Real Terms
The numbers are worth sitting with for a moment. The panel spans just over 97.5 inches diagonally, which translates to a physical width of approximately 218 centimeters — roughly the length of a standard interior door laid horizontally. Height reaches around 125 centimeters. This is a two-person installation at minimum, and a four-person job in most homes when handled with proper care.
Before purchasing, calculate your actual viewing distance. THX and SMPTE guidelines suggest an optimal seating position of 3.5 to 4 meters from the screen for 4K content — closer than most people expect, and proof that the immersion this panel delivers is physics, not marketing.
Panel Depth and Wall Mount Compatibility
Despite its mass of nearly 54 kilograms, the 98A400 measures just 44.5 millimeters at its deepest point — under two inches. That slim profile won't protrude awkwardly from a wall mount. Standard VESA compatibility means you're not locked into a proprietary bracket system; a wide range of heavy-duty third-party mounts fit. Budget for one rated for screens above 50 kilograms, and treat professional installation as a practical necessity rather than an optional upgrade at this weight.
Finish and Anti-Reflection Coating
Bezels are narrow relative to the panel size, directing visual attention toward the picture rather than the frame. The anti-reflection coating on the screen surface is not a checkbox feature at this scale — a highly reflective 98-inch panel in a normally lit room would be genuinely difficult to watch during daylight. The coating meaningfully reduces glare from windows and overhead lighting without degrading the image.

Display Performance
Breaking down the panel technology and what it means for your actual viewing experience
The Technology Stack: QLED Explained
The 98A400 uses a QLED panel — LED-backlit LCD enhanced with a quantum dot filter layer. Quantum dots absorb blue LED light and re-emit it as precisely tuned red and green wavelengths, dramatically expanding the color range the panel can reproduce compared to standard LED-LCD. This is not OLED — there are no self-emitting pixels, and individual pixel-level light control is not possible — but QLED at this screen size and price point is the practical choice for brightness output and long-term longevity.
Color Volume
1.07 Billion Colors
10-bit color depth eliminates banding in gradients. Sunsets, skin tones, and dark skies render smooth and nuanced rather than stepping between visible shades.
Brightness
450 Nits Typical
Comfortable for moderately lit rooms and dark home theaters. Not class-leading for ultra-bright HDR specular highlights in rooms with strong ambient light.
Native Contrast
6,000:1
Strong for an LCD-based panel. Dark scenes retain shadow detail without blacks lifting to a distracting gray — a meaningful step above entry-level large-format TVs.
Refresh Rate and Motion Handling
144Hz is the specification that separates the 98A400 from most large-format televisions, which typically top out at 60Hz or 120Hz. For broadcast TV, streaming, and films — all delivered at 24, 30, or 60 frames per second — the extra headroom lets motion processing interpolate with cleaner multiples, reducing judder in fast-moving content like sports and action sequences.
For PC gamers, 144Hz is the immediately impactful number. Connected to a capable graphics card via any of the four HDMI 2.1 ports, this TV can display 4K PC games at up to 144 frames per second — a combination that was essentially unavailable in consumer televisions until recently. Console players on PS5 or Xbox Series X are capped at 120fps, which is still well above what the majority of large-format TVs support.
HDR Format Support
| HDR Format | Supported | Real-World Impact |
|---|---|---|
| HDR10 | Universal baseline standard across all 4K Blu-rays, streaming services, and gaming platforms | |
| HDR10+ | Dynamic scene-by-scene tone mapping from Amazon Prime Video and select Blu-ray releases | |
| Dolby Vision | Premium HDR tier from Netflix, Disney+, and Apple TV+ — the reference standard for streaming HDR delivery | |
| HLG | Live broadcast standard for over-the-air HDR signals and compatible cable sources |
178° Viewing Angles
Horizontal and vertical viewing angles both reach 178 degrees. Viewers seated to the far sides of a wide couch won't experience the color shift and contrast loss that afflicts many LCD panels when viewed off-axis. On a screen this large, some seats are inevitably off-center — wide angles are a practical necessity, not a bonus.
AMD FreeSync
When connected to a compatible PC graphics card or Xbox console, FreeSync matches the TV's refresh rate to the source's frame output in real time, eliminating screen tearing and reducing stutter. On a 98-inch screen, screen tearing is far more visually disruptive than on a monitor — FreeSync removes it entirely for compatible sources.
Audio: Capabilities and Honest Limitations
What the built-in system can deliver — and what you should plan beyond it
Built-In Speaker System
The 98A400 integrates stereo speakers with a combined output of 20 watts — two 10-watt drivers. The system decodes Dolby Atmos, Dolby Digital Plus, Dolby Audio, and DTS:X natively, meaning it can process premium spatial audio from streaming services and physical media. Whether you actually hear the full effect those formats are designed to deliver depends entirely on the speakers physically reproducing them.
Two 10-watt drivers housed in a flat panel cabinet are physically constrained in what they can produce. Bass extension is limited without a dedicated subwoofer, and dynamic range compresses at high volumes. In a quiet room with dialogue-heavy content, the built-in audio is adequate. For action films and live music, the gap between what the decoding is capable of and what the speakers can actually render will be noticeable.
The Recommended Audio Path
The HDMI eARC port makes soundbar or AV receiver integration lossless. eARC supports high-bandwidth audio formats including Dolby Atmos TrueHD and DTS:X — the same formats found on 4K Blu-ray — passed from the TV to an external system without compression. A mid-range soundbar with a wireless subwoofer will transform the experience on a screen this size. For a dedicated home theater room, a full AV receiver and speaker system will match the visual scale appropriately.
There is no 3.5mm headphone output on this TV. Private listening requires a Bluetooth headset via the built-in Bluetooth 5.4 connection — worth planning for if late-night viewing without disturbing others is part of your household routine.

Smart TV Platform and Connectivity
What's built in, what connects, and where the limits are
Smart Platform and Voice Control
The 98A400 runs a full smart TV platform with an extensive app ecosystem, a built-in browser, and Google Assistant integration. Google Assistant means you can search content across apps, control smart home devices, and get answers through the remote — without needing a separate smart speaker. USB recording is also supported, allowing you to write live broadcast content directly to an attached USB drive from a compatible antenna or tuner source.
AirPlay 2 allows iOS and macOS users to mirror or stream content from iPhones, iPads, and Macs wirelessly — useful for sharing photos, streaming from apps without dedicated TV versions, or mirroring a laptop screen. Miracast provides the equivalent wireless display capability for Android and Windows devices. Smartphone remote control support is included for users who prefer their phone over the physical remote.
Four HDMI 2.1 Ports: Why It Matters
Four HDMI 2.1 ports at full 48Gbps bandwidth is exceptional at this price tier. Most competing televisions offer two HDMI 2.1 ports and fill the remaining slots with older HDMI 2.0 connections. Here, all four ports support 4K at 144Hz, Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM) — meaning multiple high-performance gaming sources can be connected simultaneously without any compromise. Wired Ethernet is available and recommended for 4K streaming; it eliminates the packet loss and interference variability that affects even strong Wi-Fi connections when delivering high-bitrate HDR content.
Physical Connections
| Connection | Count | Notes |
|---|---|---|
| HDMI 2.1 | 4 | All full-bandwidth; one port with eARC |
| USB | 2 | Media playback + USB recording |
| Ethernet (RJ45) | 1 | Recommended for stable 4K streaming |
| Wi-Fi | — | Wi-Fi 5 (802.11ac) + Wi-Fi 4 |
| Bluetooth | 5.4 | Headsets, keyboards, peripherals |
| Digital Audio Out | 1 | For legacy audio systems |
| AirPlay 2 | iOS and macOS wireless display | |
| Miracast | Android and Windows wireless display | |
| Headphone Jack | Not present; use Bluetooth instead |
Who This TV Is For — and Who Should Look Elsewhere
Matching the right buyer to the right product is the most important part of any large-format purchase decision
This TV Fits Well If...
You have a room large enough to maintain a 3.5–4 meter viewing distance and want the closest consumer approximation to a cinema screen. The Dolby Vision and Dolby Atmos stack, combined with the 144Hz panel, means the hardware won't be the bottleneck in your system for years.
Four HDMI 2.1 ports, 144Hz, FreeSync, VRR, and ALLM make this one of the most capable gaming displays available at any screen size. Gaming at 98 inches from 3.5 meters is an experience no monitor — regardless of how premium — can replicate.
At 98 inches with 178° viewing angles, multiple viewers at various positions all see a clear, consistent image. The 144Hz refresh rate keeps motion in fast-moving sport clean. When watching live sport is social, the size is the feature.
Dolby Vision, HDR10+, HDR10, and HLG are all natively supported. No premium content from any streaming service, 4K Blu-ray, or broadcast source will be refused or silently downgraded to a lesser format.
Consider Alternatives If...
In rooms smaller than roughly 4 by 5 meters, this TV will dominate the space uncomfortably and may not be viewable at an appropriate distance. Size requires space — this is not a TV you add to an average-sized room.
Buyers who watch a lot of classic cinema in a dark room and prioritize absolute black levels may prefer an OLED alternative at a smaller screen size. OLED's self-lit pixels deliver contrast that no LCD can match.
Only Google Assistant is natively integrated. Amazon Echo users wanting direct TV control, and Apple HomeKit households, will find smart home compatibility limited to workarounds that add friction.
The built-in speakers need reinforcement to do justice to a 98-inch visual experience. A soundbar or AV receiver is less optional here than on a smaller screen — factor that cost into the total budget before purchasing.

Strengths and Weaknesses
An honest assessment — the trade-offs that determine whether this TV fits your needs
What the 98A400 Gets Right
Four Full-Bandwidth HDMI 2.1 Ports
Rare at this price category. All four ports support the full bandwidth required for 4K at 144Hz, VRR, and ALLM — meaning the TV is genuinely future-resistant for high-performance gaming and source devices for years to come.
144Hz with AMD FreeSync
A combination most large-format TVs don't offer. Motion in gaming and fast-moving content is visibly smoother, and screen tearing is eliminated for compatible gaming sources — a meaningful difference on a screen this large.
Complete HDR Format Coverage
HDR10, HDR10+, Dolby Vision, and HLG are all natively supported. No HDR content from any major streaming service, 4K Blu-ray, or broadcast source will be refused or silently downgraded.
Solid Native Contrast for an LCD Panel
At 6,000:1, the native contrast ratio is a meaningful step above the 1,000:1 to 3,000:1 figures typical of entry-level large-format TVs. Dark scenes have depth and shadow detail without the washed-out gray that undermines cheaper panels.
178° Viewing Angles Suited to the Scale
Wide viewing angles are a practical necessity at 98 inches. Off-axis seating — unavoidable on a screen this wide — doesn't compromise the image for viewers positioned at the sides of the room.
Where the Trade-offs Show
Peak Brightness Below Top-Tier Rivals
At 450 nits typical, the panel won't deliver the intense specular highlight brilliance that flagship Mini-LED TVs achieve. Buyers who want dramatic HDR punch in bright rooms will notice the ceiling under real-world viewing conditions.
Built-In Audio Needs External Reinforcement
20 watts across two drivers is physically modest relative to the visual scale of this panel. A soundbar or AV receiver is less optional here than on a smaller screen — budget for one as part of the total purchase plan.
No Alexa or Apple HomeKit Integration
Only Google Assistant is natively supported. Amazon Echo and Apple HomeKit users will need workarounds that add friction to everyday smart home control scenarios.
No Headphone Jack
Private listening requires a Bluetooth headset. Users who prefer wired headphones for lower-latency audio need a third-party Bluetooth transmitter to bridge the gap.
Standard One-Year Warranty
Industry-standard coverage for this category, but on a 98-inch panel where service logistics are complex and costly, an extended protection plan is worth factoring into the total cost of ownership from the outset.

Final Verdict
TCL 98A400 — 98-Inch QLED Television
The TCL 98A400 is a serious large-format television that earns its footprint. It is not a compromised budget option masquerading as a flagship — it carries genuinely capable credentials: four full-bandwidth HDMI 2.1 ports, 144Hz at 4K, the complete HDR quartet including Dolby Vision, a strong native contrast ratio, and wide viewing angles that suit its physical scale.
Where it asks for understanding: peak brightness that won't match top-tier Mini-LED rivals, and built-in audio that needs external reinforcement to do justice to the visual experience. Neither is a disqualifier — they are the natural trade-offs of this feature set at this price. The one-year warranty is standard for the category but warrants extended coverage consideration given the complexity of any service scenario at this size and weight.
Buy This If...
You have the room, the viewing distance, and a budget that includes external audio. For home theater enthusiasts, sports households, and gamers who want screen scale as part of their setup, the 98A400 delivers a genuinely cinematic experience that nothing smaller can replicate at this price tier.
Look Elsewhere If...
Your room cannot support the viewing distance, deep black-level performance for dark film content is your primary goal, or native Alexa or Apple HomeKit integration is non-negotiable for your smart home setup.
