A large television can make movies, sports, and games feel more immersive, but size alone does not guarantee a satisfying picture. Bright rooms, viewing distance, motion handling, sound quality, and smart features all affect whether a screen feels like a genuine upgrade.
We assembled this guide to Best Big Screen TVs Under $700 around TCL QM64L models with Mini LED backlighting, QLED color, 4K resolution, and gaming-focused features. The comparison helps you understand which specifications matter before choosing a screen for your living room, bedroom, media space, or gaming setup.
Television shoppers commonly focus on diagonal size while overlooking brightness, viewing distance, panel contrast, and available HDMI features. Our guide explains those trade-offs and shows how the current options fit different room layouts, entertainment habits, and expectations for 2026.
If you are also planning a broader home upgrade, our Home and Living category guides offer additional ideas for practical improvements around the house.
Best Big Screen TVs Under $700 Buying Guide
1. Screen Size and Viewing Distance
Screen size changes immersion, furniture placement, and viewing comfort more than almost any other television specification. A larger panel can reveal more cinematic detail, but it may overwhelm a narrow room or force you to move your seating too close.
Measure the distance from your usual seating position to the wall before comparing models. For a 4K television, many viewers find a distance around one to one and a half times the screen’s diagonal dimension comfortable, although personal preference and content quality still matter.
The TCL 55-Inch QM64L Series suits viewers who want a substantial picture in a smaller room, while the TCL 65-Inch QM64L Series creates a more theater-like presentation. Leave enough wall and cabinet space for ventilation, cable access, and a centered viewing position.
2. Backlighting and Contrast
Backlighting determines how effectively a television separates dark shadows from bright highlights. Standard edge-lit LED sets can look acceptable in general viewing, but limited light control may produce gray blacks or visible blooming around bright objects.
Both TCL QM64L models use QD-Mini LED technology with a Halo Control System and up to 500 local dimming zones. Local dimming divides the backlight into independently controlled areas, allowing the screen to darken portions of an image while keeping highlights bright.
When comparing televisions, look beyond labels such as LED, QLED, or Mini LED and check whether local dimming is actually included. More zones do not automatically create perfection, but controlled zones generally provide a stronger contrast foundation for movies, nighttime scenes, and HDR material.
3. Brightness for Your Room
Brightness matters most when sunlight, lamps, or pale walls compete with the image. A television that looks impressive in a dark showroom may lose shadow detail or appear washed out when placed opposite a bright window.
HDR brightness helps preserve detail in highlights such as sunlight, explosions, reflections, and stadium lights. The TCL QM64L models are designed for strong HDR visibility in bright rooms, making them more flexible than many basic televisions with modest backlight output.
Identify the room’s brightest viewing period before buying. If you watch mostly during daylight, prioritize a bright Mini LED display and consider curtains that reduce direct glare, because brightness cannot completely eliminate reflections from uncovered windows.
4. Resolution, Color, and HDR Formats
4K resolution provides a detailed 3840 by 2160 image, which is especially useful on a large screen viewed from a moderate distance. It gives streaming services, game consoles, and compatible discs enough pixel density to look crisp without requiring an extremely expensive panel.
Quantum Dot color expands the range and intensity of shades compared with many conventional LED screens. The QM64L models support Dolby Vision, HDR10+, HDR10, and HLG, covering the major HDR formats used by streaming platforms, broadcasts, games, and home video sources.
Do not choose a television solely because its box lists several HDR standards. Pair format support with strong backlight control and brightness, since an HDR label has limited value when a screen cannot reproduce convincing contrast or visible highlight detail.
5. Refresh Rate and Motion Handling
Refresh rate describes how frequently the panel can update the image, while motion processing influences how smoothly fast action appears. Sports, racing games, camera pans, and action films can expose weaknesses that remain hidden during slow dialogue scenes.
Both QM64L televisions offer a native 144Hz refresh rate, along with VRR, ALLM, Motion Rate 480, and Game Accelerator 240. These features can reduce judder and improve responsiveness when compatible games or devices send an appropriate signal.
For ordinary television and most films, a very high refresh rate is not essential. It becomes more valuable when you watch frequent live sports or play fast competitive games, so match this specification to your habits rather than paying attention to the largest motion number alone.
6. Gaming Connections and Input Features
A gaming-friendly television must respond quickly and maintain smooth movement, but its usefulness also depends on connections. Before buying, count your console, streaming device, sound system, and computer inputs so you know whether frequent cable swapping will be necessary.
Variable refresh rate helps synchronize the panel with a compatible console or computer, reducing tearing when frame delivery changes. Auto Low Latency Mode can switch the television into a faster gaming mode automatically, reducing the chance that you leave unnecessary picture processing enabled.
Use a high-speed certified cable for modern consoles and gaming computers, especially when targeting high refresh rates or advanced HDR signals. Also check the television’s detailed connection specifications before purchase, because feature names alone do not confirm that every input supports every gaming mode.
7. Viewing Angles and Room Layout
Viewing angle affects how color and contrast hold up when people sit away from the center of the screen. This matters in wide living rooms, open-plan spaces, and homes where several viewers regularly watch from different chairs.
The QM64L models use an HVA panel with a stated 178-degree horizontal and vertical viewing angle. That specification suggests useful flexibility for side seating, although perceived contrast can still vary depending on content, lighting, and how far viewers sit from the central axis.
Mark the likely seating positions with temporary chairs before mounting a large television. If most viewers sit directly opposite the screen, contrast and black-level performance may matter more than extreme side-angle performance, while a wide sectional makes viewing-angle behavior more important.
8. Built-In Audio and Sound Planning
Thin televisions often produce thin sound because there is limited cabinet space for speakers. Dialogue may remain understandable, but explosions, music, and atmospheric effects can lack depth unless the television has a more capable integrated audio system.
Each QM64L model includes an Onkyo 2.1 audio arrangement with Dolby Atmos, DTS Virtual:X, and DTS:X passthrough support. The built-in speaker design can provide a fuller starting point than basic stereo speakers, particularly for casual viewing without a separate soundbar.
Check your room’s acoustic limits before assuming any television will deliver cinema-level sound. A soundbar or receiver may still be worthwhile in a large, open room, while the built-in system can be adequate for bedrooms, apartments, and everyday programs.
9. Smart Platform and Voice Control
The smart platform determines how easily you access streaming services, search for programs, manage devices, and receive software updates. A responsive interface can make daily use more pleasant, while an unfamiliar or cluttered system may undermine an otherwise excellent picture.
These TCL televisions use Smart Fire TV and include built-in Alexa+ functionality with natural-conversation control, personalized recommendations, and hands-free or push-to-talk voice options. That setup may appeal to households already using Alexa devices and Amazon services.
Review privacy settings, microphone controls, and app availability during setup rather than accepting every default. If you already own a preferred streaming stick, compare its interface with the built-in platform and confirm that your essential services work without additional hardware.
| Buying factor | TCL 55-Inch QM64L Series | TCL 65-Inch QM64L Series |
|---|---|---|
| Display type | QD-Mini LED QLED 4K UHD | QD-Mini LED QLED 4K UHD |
| Refresh and gaming | 144Hz, VRR, ALLM, Game Accelerator 240 | 144Hz, VRR, ALLM, Game Accelerator 240 |
| HDR support | Dolby Vision, HDR10+, HDR10, HLG | Dolby Vision, HDR10+, HDR10, HLG |
| Audio platform | Onkyo 2.1 with Dolby Atmos and DTS:X passthrough | Onkyo 2.1 with Dolby Atmos and DTS:X passthrough |
| Best fit | Smaller rooms and closer seating | Larger rooms and more immersive viewing |
The two models share the central picture and gaming platform, so the most meaningful distinction is physical scale. Use the 55-inch version when seating distance or furniture width limits you, and move to the 65-inch version when immersion is the priority.
