Last updated: May 16, 2026 • TCL QM8 reviewed across 6 weeks against Hisense U8, Samsung S95F, and LG C5
- 3,719 nits peak HDR — matches Samsung S95F QD-OLED at less than half the price
- 4,000 mini-LED zones with 26-bit backlight controller — blooming nearly eliminated
- Full Dolby Vision IQ + HDR10+ — the format coverage rivals OLED flagships
- $1,498 for the 65-inch — same price as the LG C5 OLED but 3× the peak brightness
- 12.6ms gaming input lag — OK for console gaming but behind OLED competitors
The TCL QM8 is the mini-LED panel that finally closes the gap with OLED on the metrics that matter most in bright rooms — HDR peak brightness, color volume, and contrast control. With 4,000 local dimming zones (more than triple last year's QM7) and a 26-bit bi-directional backlight controller, blooming has been reduced to the point where it's only visible in worst-case scenarios.
This review is based on 6 weeks of mixed-use viewing (HDR Blu-ray, PS5 gaming, Apple TV 4K Dolby Vision content, and daytime sports), cross-referenced against peer measurements from RTINGS, TechRadar, FlatpanelsHD, and Tom's Guide.
Brightness: where the QM8 wins decisively
This is the QM8's headline number, and it's not marketing fluff — the panel genuinely delivers OLED-flagship-level peak brightness for less than half the price:
| Measurement (peak nits, 10% window) | TCL QM8 65" | Samsung S95F 65" | LG C5 OLED 65" |
|---|---|---|---|
| Filmmaker mode | 2,750 nits | 2,100 nits | 980 nits |
| Vivid mode peak | 3,719 nits | 3,789 nits | 1,180 nits |
| Sustained 100% white | 760 nits | 365 nits | 195 nits |
The QM8 holds sustained brightness better than any OLED — 760 nits across a 100% white window vs 365 on the S95F and 195 on the C5. This means daytime sports, news with white backgrounds, and HDR content with large bright areas (snow, sky, beaches) look genuinely impressive in a way that even flagship OLEDs cannot match.
In Filmmaker mode the QM8 measures 2,750 nits peak HDR — that's higher than the Samsung S95F's 2,100 nits in the same mode. Watching HDR content with calibrated settings, the QM8 produces more impactful specular highlights than the S95F. The difference is visible in side-by-side comparison.
Blooming: the mini-LED weakness
This is where mini-LED still loses to OLED, and where buyers need honest data:
What you'll see:
- Subtitle blooming on letterbox bars — white text on black movie bars shows a soft halo around each letter. Visible on every mini-LED including the QM8.
- Star fields and fireworks — bright objects on near-black backgrounds show halos. The 4,000 zones reduce this dramatically vs prior generations, but it's still detectable.
- Off-axis viewing — blooming becomes more visible when viewed at 30+ degrees off-center. Center-seat viewing is fine; couch-side viewing shows more halos.
What you won't see:
- Blooming in normal HDR movies, gaming, and TV content viewed straight-on
- Black-level lifting during dark scenes (the 4,000 zones genuinely deliver near-OLED black floors in most content)
- Mini-LED's traditional weakness with subtle dark gradients (significantly improved by the 26-bit controller)
For 95% of viewing situations, you won't notice blooming. For the 5% where it's visible (specific scenes, off-axis seating), the QM8 is still mini-LED and an OLED would handle it perfectly.
HDR format support
This is where TCL beats Samsung outright — the QM8 supports every major HDR format:
- Dolby Vision IQ — adjusts HDR based on ambient light (same as LG)
- Dolby Vision 2 Max — arriving in summer 2026 software update
- HDR10+ Adaptive — dynamic metadata for Amazon Prime Video and Samsung-mastered content
- HDR10 and HLG for broadcast HDR
For anyone watching Apple TV 4K, Disney+, or Netflix Originals (mostly Dolby Vision) plus Amazon Prime Video (HDR10+), the QM8 plays everything in its mastered format. Samsung's S95F doesn't — you lose Dolby Vision on Samsung. This is a real functional advantage the QM8 holds over Samsung's entire flagship line.
Gaming: capable but not class-leading
For console gaming at 4K/120Hz, the QM8 is competent:
- 4× HDMI 2.1 ports at 48Gbps
- 144Hz native refresh for PC gaming
- VRR + AMD FreeSync Premium Pro + ALLM
- 12.6ms input lag at 4K/60Hz Game Mode (RTINGS measurement)
- Dolby Vision Gaming at 4K/120Hz for compatible titles
The 12.6ms input lag is the QM8's gaming weakness — the Samsung S95F is 10× faster at 1.3ms, the LG C5 is 5.2ms. For casual gaming and most console titles, the difference is imperceptible. For competitive multiplayer (Apex, Valorant, fighting games), the OLED competitors are measurably more responsive.
Pros & cons
- 3,719 nits peak HDR at 65" — matches Samsung S95F at < half the price
- 4,000 mini-LED zones with 26-bit controller — blooming nearly eliminated
- Full Dolby Vision + HDR10+ + Dolby Vision 2 Max — broader format support than Samsung flagships
- 760 nits sustained fullscreen — brighter than any OLED for daytime viewing
- Comes in 98-inch at $4,997 — no OLED competitor exists at that size and price
- Google TV with Chromecast built-in — smoother than Tizen, fewer ads than webOS
- 12.6ms input lag — behind OLED competitors for competitive gaming
- Visible blooming on letterbox subtitles and off-axis viewing — mini-LED's permanent trade-off
- QC variance — reports of dead-on-arrival panels and backlight failures (verify on receipt)
vs the competition
TCL QM8 vs Samsung S95F QD-OLED
The S95F has lower input lag (1.3ms vs 12.6ms), perfect blacks (no blooming), and a superior matte anti-glare coating. The QM8 matches the S95F on peak HDR brightness, beats it on sustained brightness, supports Dolby Vision (Samsung doesn't), and costs $700 less at 65". Pick the QM8 if HDR brightness in bright rooms matters more than competitive gaming or perfect blacks; pick the S95F if input lag and OLED contrast matter most.
TCL QM8 vs LG C5 OLED
Both are priced around $1,300-$1,500 at 65". The C5 has perfect OLED blacks, Dolby Vision (same as QM8), 5.2ms input lag (better gaming), and runs cooler in sustained viewing. The QM8 is 3× brighter in HDR peak, brighter in sustained fullscreen, and comes in sizes up to 98-inch. Pick the C5 if you watch in moderate-to-dark lighting and value perfect blacks; pick the QM8 if your room is bright or you want a screen larger than 83-inch.
TCL QM8 vs Hisense U8
The Hisense U8 is the QM8's closest mini-LED competitor. The QM8 has more zones (4,000 vs U8's 1,500-3,000), higher peak HDR brightness (3,719 vs ~2,900 nits), and Google TV (vs Hisense's VIDAA). The U8 is roughly $200-400 cheaper. Pick the QM8 for maximum brightness and Google ecosystem; pick the U8 if you want similar performance for less and don't mind VIDAA.
Pricing
| Size | MSRP | Typical street price |
|---|---|---|
| 65-inch | $2,499 | $1,498 |
| 75-inch | $2,999 | $1,998 |
| 85-inch | $3,999 | $2,798 |
| 98-inch | $6,499 | $4,997 |
The 85-inch at $2,798 is where the QM8 becomes a category-defining purchase — OLED at 85-inch starts at $4,500+ (Samsung S95F 83") or doesn't exist at the size. For buyers wanting maximum screen real estate without the LG G3 wallet-emptying premium, the 85-inch QM8 is the only realistic option.
Who should buy the TCL QM8
Worth it for
Bright-room viewers where peak HDR brightness matters more than perfect blacks. Daytime sports households watching with sunlight or overhead lights on. Anyone wanting a screen 85-inch or larger — OLED at that size costs $4,500+. Apple TV 4K and Netflix users who need Dolby Vision but want mini-LED brightness instead of OLED. Console gamers who can tolerate 12.6ms input lag.
Not worth it for
Competitive multiplayer gamers who need 5ms-or-lower input lag — the Samsung S95F is 10× faster. Movie purists watching in pitch-black home theaters — the OLED blacks of the LG C5 or G5 are perceptibly deeper. Buyers who detect mini-LED blooming easily — if your eye picks up halos on letterboxed subtitles, you'll see them on the QM8 (just less than on older mini-LEDs). Anyone who needs absolute QC reliability — TCL's panel-level QC variance is real.
Our verdict — 8.7/10
The TCL QM8 is the best non-OLED TV of 2026 and the right choice when bright-room HDR brightness, large-screen sizes, or budget matter more than perfect blacks. At $1,498 for the 65-inch, it delivers Samsung-S95F-class HDR brightness for $700 less — with the added Dolby Vision support Samsung doesn't offer.
It's not an OLED replacement — the input lag, viewing angles, and worst-case blooming will always reveal the mini-LED architecture. But for the right room and the right use case, the QM8 delivers a flagship experience at a mid-range price. Earns our Best Smart TV 2026 "Best Value" verdict.
Frequently Asked Questions
Is the TCL QM8 better than an OLED?
For bright rooms and HDR brightness, yes — the QM8 hits 3,719 nits peak HDR, which matches or exceeds the Samsung S95F QD-OLED (3,789 nits) at less than half the price. For dark-room movie viewing with perfect blacks and zero blooming, OLED still wins. The QM8 is the right choice if your room has windows, daytime sports viewing matters, or budget is tight. OLED wins in controlled-lighting home theaters.
Does the TCL QM8 have noticeable blooming?
Yes, but significantly reduced versus prior-generation mini-LED. With 4,000 dimming zones and TCL's 26-bit bi-directional backlight controller, blooming is essentially invisible during normal HDR content viewed straight-on. It becomes noticeable in three scenarios: (1) bright white text or subtitles on letterbox black bars, (2) fireworks or bright objects on near-black backgrounds, and (3) viewed off-axis at greater than 30 degrees. For a flagship mini-LED, the blooming control is among the best in 2026.
What sizes does the TCL QM8 come in?
The QM8 is available in 65-inch ($1,498 street price), 75-inch ($1,998), 85-inch ($2,798), and 98-inch ($4,997) sizes. The 85-inch is where the QM8 becomes a category-killer — OLED at 85-inch costs $4,500+, while the QM8 delivers comparable HDR brightness for $2,798. The 65-inch is competitive with the LG C5 OLED at $1,299.
Does the TCL QM8 support Dolby Vision and gaming features?
Yes. Dolby Vision, Dolby Vision IQ, HDR10+, HDR10, and HLG are all supported, with Dolby Vision 2 Max arriving in a software update planned for summer 2026. Gaming features include 144Hz native refresh, VRR, ALLM, AMD FreeSync Premium Pro, and 4× HDMI 2.1 ports. Input lag at 4K/60Hz is 12.6ms in Game Mode — higher than OLED competitors (Samsung S95F: 1.3ms, LG C5: 5.2ms) but well below the 20ms threshold for casual and most competitive gaming.
TCL QM8 vs Hisense U8 — which mini-LED wins?
Both are top-tier mini-LED competitors. The TCL QM8 has more dimming zones (4,000 vs Hisense U8's 1,500-3,000 depending on size), brighter peak HDR (3,719 vs U8's ~2,900 nits), and Google TV instead of VIDAA. The Hisense U8 is roughly $200-400 cheaper and has slightly better software responsiveness. For maximum HDR brightness and ecosystem compatibility, pick the QM8. For pure price-to-performance, the Hisense U8 is close.
Are there known reliability issues with the TCL QM8?
Some buyers have reported backlight failure or dead-on-arrival panels — quality control concerns more visible at TCL's price tier than at Samsung or LG's flagship tiers. TCL offers a 1-year manufacturer warranty plus 30-60-day retailer returns, so verify panel condition immediately on receipt. The vast majority of units function reliably long-term, but the QC variance is real and worth knowing before purchase.
