TCL Q6 Q-Class 75Q651G 75"

★★★★★ 5.0 (5)

The 75-inch QLED panel with Dolby Vision and a 120Hz refresh rate delivers fluid motion for sports, aided by the TCL AIPQ processor’s deep learning upscaling. Its Google TV platform provides broad smart home integration with Apple HomeKit and hands-free voice control, while the direct LED backlight offers solid value at this screen size. This set is best for sports enthusiasts wanting a large, smooth display without stepping up to premium OLED pricing.

Snapshot

The 30-Second Version

A 75-inch QLED with top-tier HDR for under $900 is an absolute win. Just don't expect cutting-edge ports or audio.

Pros & Cons

Pros

  • Incredible HDR for the price, top of the charts 96th
  • Huge 75-inch screen with strong QLED color 87th
  • 120Hz panel with VRR makes gaming smooth 74th
  • Google TV is simple and has every app 74th

Cons

  • HDMI 2.0 limits 4K 120Hz gaming to compressed color
  • Wi-Fi 5 feels dated on a new smart TV
  • Audio is just average, plan on a soundbar
  • Only 3 HDMI ports, and one is eARC

The proof

Performance

What surprised us most is how good the HDR looks. We're talking 96th percentile good, which means it's hanging with sets that cost twice as much in that specific area. The QLED panel and Dolby Vision support do some heavy lifting here, and the AIPQ processor keeps motion smooth with MEMC frame insertion. Gaming is solid too at 120Hz with VRR, though it's held back by those HDMI 2.0 ports. The display overall sits in the 87th percentile, so it's a standout for the money. Audio is middle of the pack, and the smart platform is fine but not snappy enough to impress.

vs Competition

The Hisense U8 Series is the natural rival here. It'll give you better brightness and more gaming features like HDMI 2.1, but you'll pay more for the privilege. The Roku Pro Series is another option if you want a simpler smart system, but its picture can't touch the TCL's HDR pop. If you're even glancing at the Sony BRAVIA XR or LG G5, you're in a completely different price bracket. For big-screen value, the TCL Q6 smokes them on cost per inch, even if it loses on absolute performance.

Price

Value & Pricing

At $870 for 75 inches, this is a steal. You're getting a display and HDR experience that rivals much pricier sets. If pure screen size and picture punch are your priorities, the value here is hard to beat. Just know you're saving money on the ports and processing speed, not the panel itself.

Overview

The TCL Q6 is the big-screen budget champ that doesn't feel like a compromise where it counts. For under $900, you're getting a massive 75 inches of QLED color with Dolby Vision that punches way above its price tag. The one thing to know is this: the HDR performance is genuinely excellent, landing in the 96th percentile of all TVs we track. That's best-in-class territory, and it makes everything from Netflix nature docs to the latest Marvel movie look rich and vibrant. Just don't expect it to be a flawless all-rounder.

Common Questions

Q: Does this TV have HDMI 2.1 for PS5 and Xbox Series X?

Nope, it's HDMI 2.0. You can still get 120Hz at 1440p or 1080p, but 4K 120Hz will use chroma subsampling. It's fine for most people, but competitive gamers will notice.

Q: How's the sound quality without a soundbar?

It's passable for news and sitcoms, but the built-in speakers are pretty thin. For anything with a soundtrack or explosions, you'll want a soundbar. The eARC port makes hooking one up painless.

Q: Is the Google TV interface slow?

It's not blazing fast. Navigation is fine for a while, but it can get a little sluggish over time as apps update. A dedicated streaming stick will feel snappier if that bugs you.

Who Should Skip This

If you need four HDMI 2.1 ports for a high-end gaming setup, this isn't your TV. Go grab an LG G5 or a Sony BRAVIA XR instead. You'll pay a lot more, but you'll get the full bandwidth and lower input lag that serious gamers want.

Verdict

Buy this if you want a massive, beautiful screen for movies and shows and don't want to spend a fortune. The HDR is the real deal, and the 120Hz panel keeps sports and gaming fluid. Just grab a streaming box down the line if the Google TV interface starts to lag, and definitely budget for a soundbar. For the price, it's an easy recommendation.
