TCL Q651G TV Review: Great Value, With Some Trade-Offs

Introduction

The TCL Q651G is part of TCL’s Q6/Q651G line (2024) aimed at delivering a 4K QLED experience at a budget-friendly price. It offers features like QLED colour technology, the Google TV smart platform, and gaming-friendly specs such as Game Accelerator modes. HomeTheaterReview+2TCL+2
However, while it brings a lot for the money, it also makes some compromises in picture quality and features.

✅ What the TCL Q651G Does Well

Strong Gaming Features

The Q651G supports TCL’s “Game Accelerator” mode with 1440p @ 120 Hz and VRR (Variable Refresh Rate) on certain sizes. That makes it an appealing option for gamers looking for smoother gameplay without spending top-tier money. RTINGS.com+1
The input lag is also solid for its price range according to review sources. HomeTheaterReview

Good Colour and QLED Technology

With QLED (Quantum Dot) technology, the TV offers vibrant colours and improved colour gamut compared to standard LED sets. The TCL site lists features like “QLED PRO – Quantum Dot Technology” and “High Brightness+ LED Backlight.” TCL
Also, reviews highlight that colour accuracy in SDR (standard dynamic range) is decent for its class. RTINGS.com+1

Affordable 4K Option

For those on a tighter budget, the Q651G offers a 4K QLED TV with Google TV smart features, HDR support (like Dolby Vision), and decent size options. One review described it as a “budget-friendly powerhouse for 2024.” HomeTheaterReview

Solid Smart Platform & Features

It runs Google TV, which many users find intuitive and feature-rich. It also supports HDR formats like Dolby Vision, HDR10+, HDR10, and HLG in many models. TCL

❌ Where the TCL Q651G Falls Short

Weak Contrast and Black Levels

A significant drawback is the lack of local dimming in the backlight. This means black levels are raised and contrast isn’t as deep as higher-end models. In darker rooms or when watching HDR content, the image can look washed out. RTINGS.com+1

☀️ Mediocre Brightness for HDR / Bright Room Use

The HDR brightness and overall peak brightness are modest. That limits how well the TV performs in bright rooms or with vivid HDR content. Reflections and glare also affect the experience. Reviews mention it’s best suited to “moderately lit environments.” RTINGS.com

Limited High-End Features for Power Users

The TV lacks some of the premium features you might find on higher-tier models: for example, it may not include HDMI 2.1 bandwidth, advanced motion-handling, or more aggressive gaming specs. If you want the very best for console next-gen or home theater, you might look higher. RTINGS.com+1

Variation by Size & Panel Refresh Rate

In smaller sizes (43″ to 75″ versions) the native refresh rate is 60Hz, which limits the benefit of “game” modes for high-frame-rate gaming. Larger models (85″ & 98″) step up to 120Hz or more. So depending on your size choice you may get different performance. RTINGS.com+1

Final Verdict

If you’re looking for a budget-friendly 4K QLED TV with decent gaming capability and solid colour performance, the TCL Q651G offers a compelling package. ✅
However, if you prioritize deep blacks, very high HDR brightness, ultra-smooth motion, or premium gaming features (HDMI 2.1, 4K@120Hz), then you may find that the Q651G makes too many compromises for your tastes.

Best for:

• Casual viewers in well-lit rooms

• Gamers on a budget who want better refresh/VRR support

• Users wanting big screen size for less money

Less ideal for:

• Home-theater purists who watch in dark rooms

• HDR enthusiasts wanting maximal brightness & contrast

• Power gamers with next-gen consoles wanting full HDMI 2.1/4K@120Hz support
