TCL Q77K Review 2026: Budget QLED TV Still Worth Buying?

Are you looking for a 4K QLED TV that packs serious gaming features without emptying your wallet? The TCL Q77K might be exactly what you need. This Costco exclusive TV launched in 2025 and continues to impress buyers well into 2026.

It offers a native 144Hz refresh rate, HDMI 2.1 bandwidth, and VRR support at a price that undercuts most competitors by hundreds of dollars. But does it cut too many corners to hit that low price?

We spent weeks gathering data, user feedback, and expert reviews to answer that question. Keep reading to find out if the TCL Q77K deserves a spot in your living room or if you should look elsewhere.

Key Takeaways

• The TCL Q77K is a Costco exclusive 4K QLED TV available in 55″, 65″, 75″, 85″, and 98″ screen sizes. It runs Google TV and includes a backlit voice remote with built in Google Assistant and Alexa compatibility.
• Gaming features punch way above its price class. You get a native 144Hz refresh rate, HDMI 2.1 bandwidth on two ports, VRR support (FreeSync, G Sync, and HDMI Forum VRR), and up to 288Hz at 1080p resolution. Input lag is extremely low.
• Picture quality is decent but limited. The Q77K uses a high contrast HVA (VA type) panel with QLED color enhancement. However, it lacks local dimming, has low peak brightness, and offers a narrow color gamut compared to Mini LED competitors.
• It is priced aggressively. The 75 inch model has been spotted at Costco for as low as $479, and the 65 inch version regularly goes on sale for around $400 to $450. This makes it one of the cheapest 144Hz TVs you can buy.
• Sound and HDR performance are weak spots. HDR content does not pop as much due to limited brightness. The built in speakers are basic and may need a soundbar upgrade.
• For pure value in the budget segment, the TCL Q77K is hard to beat if gaming features are your priority. If picture quality matters more, consider stepping up to the TCL QM6K or Hisense QD7.

TCL Q77K Overview and First Impressions

No products found.

The TCL Q77K is an entry level 4K QLED smart TV released in 2025. It is sold exclusively through Costco in North America. TCL positioned this model as an affordable option for buyers who want modern features without a premium price tag.

The TV comes in five sizes: 55 inch, 65 inch, 75 inch, 85 inch, and 98 inch. Each size uses a direct LED backlight system with an HVA (High Viewing Angle) panel. The design is clean and minimal. It has thin bezels on three sides and a slightly thicker chin at the bottom.

Out of the box, the setup process is simple. Google TV handles the software side. You sign into your Google account and all your streaming apps become available quickly. The backlit voice remote is a nice touch at this price. You can talk to Google Assistant or use Alexa voice commands right away.

First impressions of the picture are positive for the price. Colors look vivid thanks to QLED Quantum Dot technology. The VA type panel delivers solid black levels in a dark room. However, you will notice the lack of local dimming zones if you watch a lot of HDR content. Bright highlights do not stand out the way they do on Mini LED TVs.

The build quality feels appropriate for a budget TV. It is not flimsy, but it is not premium either. The plastic back panel and basic stand get the job done. Overall, the Q77K makes a strong first impression for its asking price.

Display Quality and Resolution

The TCL Q77K features a 3840 x 2160 (4K UHD) resolution with QLED color enhancement. The panel type is VA (Vertical Alignment), which gives it a natural advantage in contrast ratio. Static contrast measures around 4600:1, which is solid for this price range.

Standard definition and 1080p content upscale reasonably well to 4K. Streaming shows on Netflix and Disney Plus look sharp and clear. Fine detail reproduction is very good according to Consumer Reports testing.

Color accuracy is respectable for a budget QLED. Flesh tones appear natural and most everyday content looks pleasing. The QLED Quantum Dot layer adds a boost to reds and greens compared to standard LED TVs. However, the color gamut is narrower than what you get on Mini LED models like the TCL QM6K or QM7K.

Peak brightness is a known weakness. The Q77K manages around 300 nits of peak brightness according to DisplaySpecifications data. This is fine for SDR content in a normally lit room. But it limits the TV’s ability to deliver impactful HDR highlights.

The absence of local dimming is the biggest trade off here. Without dimming zones, bright objects create a slight glow around them on dark backgrounds. Movie watchers who value deep inky blacks and bright punchy highlights may find this frustrating.

For the price, the display quality is acceptable. It looks good with casual content, sports, and gaming. Just set your expectations correctly for HDR performance.

Gaming Performance and Features

This is where the TCL Q77K truly shines. The gaming feature set on this TV is remarkable for its price point. Many TVs costing twice as much offer fewer gaming capabilities.

The Q77K runs at a native 144Hz refresh rate across all screen sizes. HDMI ports 1 and 2 support full HDMI 2.1 bandwidth. This means you get 4K at 120Hz and even 4K at 144Hz with compatible hardware. At 1080p, the TV supports up to 288Hz variable refresh rate on models 65 inches and larger.

VRR support covers all three major formats: AMD FreeSync Premium, Nvidia G Sync Compatible, and HDMI Forum VRR. This means your PS5, Xbox Series X, or gaming PC will all take advantage of the smooth, tear free gameplay.

Input lag is extremely low. Rtings measured it at around 5 to 6 milliseconds in Game Mode at 4K 120Hz. This puts the Q77K in the same league as much more expensive gaming monitors and TVs. You will not feel any noticeable delay between pressing a button and seeing the action on screen.

The Game Master mode in the settings lets you enable VRR and fine tune gaming options. Auto Low Latency Mode (ALLM) is also supported. The TV automatically switches to Game Mode when it detects a console.

If gaming is your primary use case, the TCL Q77K offers an almost unbeatable combination of refresh rate, response time, and VRR at this budget. It was even highlighted on Reddit as the cheapest TV to enable all Xbox Series X features.

Top 3 Alternatives for TCL Q77K

If you want better picture quality or different features, here are three strong alternatives to consider.

1. TCL QM6K (Mini LED QLED)
The QM6K steps up to Mini LED backlighting with local dimming zones. It delivers significantly better HDR performance, higher brightness, and a wider color gamut. It also runs Google TV and supports 144Hz gaming. The price is higher, but the picture quality improvement is substantial.

2. Hisense QD7 Series (QLED)
The Hisense QD7 offers a similar QLED experience with a native 144Hz panel and Game Mode Pro. The 2025 QD7QF model uses Mini LED technology with full array local dimming. It runs Fire TV and supports Dolby Vision and Dolby Atmos. It competes directly with the Q77K at a slightly higher price.

3. Samsung DU7200 (Crystal UHD)
The Samsung DU7200 is a popular budget option from a trusted brand. It offers reliable 4K picture quality with PurColor technology and Motion Xcelerator. However, it lacks the 144Hz refresh rate and HDMI 2.1 features that the Q77K provides. Choose this if brand loyalty and smart TV features matter more than raw gaming specs.

Smart TV Platform and Google TV Experience

The TCL Q77K runs Google TV as its smart TV operating system. This gives you access to a clean, well organized interface that pulls content from multiple streaming services into one home screen.

Google TV learns your viewing habits over time. It recommends shows and movies based on what you watch. The “For You” tab surfaces content from Netflix, Hulu, YouTube, Disney Plus, and other installed apps. You can also create personal profiles for different family members.

The app library is extensive. All major streaming services are available through the Google Play Store. You can download apps for Apple TV Plus, HBO Max, Peacock, Paramount Plus, and hundreds more. Chromecast is built in, so you can cast content from your phone or tablet with one tap.

Voice control works well through the included backlit remote with a microphone button. Press the button and ask Google Assistant to find a show, adjust volume, or control smart home devices. Alexa voice commands are also supported if you prefer Amazon’s ecosystem.

Performance wise, the interface runs smoothly. App launch times are quick. Switching between apps does not cause long loading screens. The processor handles Google TV without major stuttering or lag.

One minor complaint is ads on the home screen. Google TV does show sponsored content and recommendations that can feel like advertisements. This is common across most smart TV platforms in 2026, but it is worth noting.

Sound Quality and Audio Features

The TCL Q77K delivers basic audio performance that matches expectations for a budget TV. The built in speakers produce clear dialogue and handle casual TV watching without major issues.

The speakers are down firing, which means sound bounces off the surface below the TV. This works fine on a TV stand. Wall mounted setups may sound slightly different depending on room acoustics.

Dolby Atmos decoding is not supported on this model. You get standard stereo output from the built in speakers. The audio lacks bass depth and does not create any sense of surround sound. Action movies and music sound flat compared to TVs with better speaker systems.

Volume output is adequate for small to medium sized rooms. You can fill a living room with enough sound for everyday watching. But if you crank the volume high, distortion becomes noticeable at the upper range.

A soundbar is strongly recommended if you plan to use this TV for movies, music, or immersive gaming. Even a budget soundbar in the $50 to $100 range will dramatically improve the audio experience. The TV has both HDMI ARC and optical audio output for easy soundbar connections.

For basic news, YouTube videos, and casual streaming, the built in speakers are serviceable. They will not impress anyone, but they get the job done for the price.

HDR Performance and Dolby Vision Support

The TCL Q77K supports Dolby Vision, HDR10, HDR10 Plus, and HLG. This broad format compatibility means it can accept HDR signals from virtually any source. However, the actual HDR experience is limited by the hardware.

Peak brightness is the main bottleneck. At roughly 300 nits, the Q77K cannot produce the bright specular highlights that make HDR content pop. Compare this to Mini LED TVs like the TCL QM7K, which can hit 3000 nits of peak brightness. The difference is dramatic.

Without local dimming, HDR contrast also suffers. The TV cannot darken specific parts of the screen while brightening others. This means a sunset scene in a movie will not have the same depth and impact you would see on a TV with zone based dimming.

Consumer Reports rated the HDR performance of the 65Q77K as “ineffective.” This does not mean the TV looks bad. It simply means the HDR processing does not add meaningful improvement over standard SDR viewing.

Dolby Vision content still looks slightly better than standard HDR10. The dynamic metadata in Dolby Vision adjusts the picture scene by scene, which helps optimize the limited brightness. But do not expect the same wow factor you see on higher end displays.

If HDR performance is a priority for you, the Q77K is not the right choice. Consider the TCL QM6K or Hisense QD7 for a meaningful HDR experience at a still affordable price.

Viewing Angles and Room Placement

The TCL Q77K uses an HVA (High Viewing Angle) panel, which is a variation of VA technology. TCL markets this as offering wider viewing angles than standard VA panels.

In practice, the viewing angles are okay. You can watch from a moderate off center position without major color shifts. However, colors do shift slightly toward blue as you move further to the sides. This is typical of VA panels, even improved ones like HVA.

For a straight on viewing position, the TV looks its best. The high contrast ratio of the VA panel creates deep blacks and punchy colors when you sit directly in front of it. A single viewer or a couple sitting close together on a couch will have the best experience.

Wide seating arrangements may be an issue. If you have a large family room with seating spread across a wide area, viewers at the extreme sides may notice washed out colors and reduced contrast. An IPS panel TV would handle wide angles better, but at the cost of lower contrast.

The TV’s brightness of around 300 nits makes it suitable for rooms with moderate ambient light. It is not bright enough to fight heavy glare from large windows. A dimly lit room or a room with curtains will provide the best picture quality.

For bedroom use, the Q77K works very well. The VA panel’s deep blacks and good contrast look great in a dark environment. This is an ideal setup for late night gaming or movie watching.

Connectivity and Port Selection

The TCL Q77K comes equipped with a solid selection of ports for a budget TV. It includes four HDMI inputs, with two of those supporting full HDMI 2.1 bandwidth. This is impressive for a TV at this price.

HDMI ports 1 and 2 are the high bandwidth ports. They support 4K at 120Hz, 4K at 144Hz, and 1080p at up to 288Hz with VRR. Ports 3 and 4 are standard HDMI 2.0 ports suitable for streaming devices, Blu ray players, or older game consoles.

You also get two USB ports for connecting external storage or powering streaming sticks. An Ethernet jack provides a wired internet connection for more stable streaming. The TV supports Wi Fi 5 (802.11ac) for wireless connectivity. Wi Fi 6 is not included, which is a minor downside.

Bluetooth connectivity allows you to pair wireless headphones, keyboards, or game controllers. An optical audio output is available for connecting to soundbars or older audio receivers. HDMI ARC is supported on one of the HDMI ports for sending audio to a compatible soundbar.

One thing to note: VRR and G Sync compatibility are limited to HDMI ports 1 and 2. If you connect a gaming console to port 3 or 4, you will not get the high refresh rate or variable refresh rate features.

The port layout is located on the back of the TV, with some ports facing outward and others facing downward. This makes cable management relatively easy for both stand mounted and wall mounted setups.

Available Sizes and Pricing

The TCL Q77K is available in five screen sizes: 55 inch, 65 inch, 75 inch, 85 inch, and 98 inch. All sizes are sold exclusively at Costco in North America and come bundled with an Allstate 3 year protection plan for a total of 5 years coverage.

Here is a breakdown of the typical pricing. The 55 inch model starts at around $299 to $349. The 65 inch version usually sells for $399 to $449. The popular 75 inch model is priced at $499 to $599 and has been spotted on sale for as low as $479 at Costco.

The 85 inch and 98 inch models offer tremendous value for large screen buyers. The 85 inch has been available around $699 to $799, and the 98 inch model offers a massive screen for around $1,299 to $1,499.

These prices make the Q77K one of the most affordable ways to get a 144Hz QLED TV with HDMI 2.1 features. Competing TVs from Samsung and LG at similar sizes often cost $200 to $500 more while offering fewer gaming features.

Costco’s generous return policy adds extra peace of mind. You get 90 days to return the TV if you are not satisfied. Combined with the Allstate warranty, this is a low risk purchase for most buyers.

The 75 inch model is the sweet spot for most living rooms. It offers a large, immersive screen at a price that feels almost too good to be true. Check your local Costco or Costco.com for the latest pricing and availability.

TCL Q77K vs TCL QM6K: Which Should You Pick?

This is one of the most common questions buyers face. Both TVs come from TCL and target budget conscious shoppers. But there are important differences.

The QM6K uses Mini LED backlighting with local dimming zones. This gives it a massive advantage in HDR performance, peak brightness, and contrast control. The Q77K uses a simple direct LED backlight without local dimming. The QM6K gets noticeably brighter and produces more vivid HDR highlights.

Color gamut is wider on the QM6K. It can display more shades of red, green, and blue. This makes content look more lifelike and vibrant. The Q77K’s QLED layer helps, but it cannot match the color volume of Mini LED plus Quantum Dot technology.

Gaming features are comparable. Both TVs support 144Hz refresh rates and VRR. Both have low input lag. The QM6K adds a slightly better motion handling algorithm, but the difference is small in real world gaming.

The QM6K runs on Google TV, just like the Q77K. Smart TV features and app availability are identical. Build quality is slightly better on the QM6K with a more refined stand and thinner profile.

Price is the deciding factor. The Q77K costs significantly less than the QM6K. If you primarily game and watch casual content, the Q77K saves you money while delivering the features that matter most for gaming. If you watch a lot of movies or care about HDR picture quality, the QM6K is worth the extra investment.

Who Should Buy the TCL Q77K?

No products found.

The TCL Q77K is an ideal TV for several specific types of buyers. Understanding where this TV excels helps you decide if it matches your needs.

Budget gamers will love this TV. The combination of 144Hz, HDMI 2.1, VRR, and ultra low input lag is exceptional at this price. If you own a PS5, Xbox Series X, or a gaming PC, the Q77K delivers a smooth and responsive gaming experience that costs a fraction of dedicated gaming TVs.

College students and first time buyers will appreciate the low price and solid feature set. You get a modern smart TV with Google TV, voice control, and access to all major streaming apps. The picture quality is more than good enough for dorm rooms and small apartments.

Secondary TV buyers looking for a bedroom, guest room, or basement TV will find the Q77K hits the right balance. It offers 4K resolution, QLED color, and smart features without the guilt of overspending on a TV for a secondary room.

Sports fans on a budget benefit from the 144Hz panel and fast motion handling. Football, basketball, and soccer look smooth and clear. The high refresh rate reduces motion blur during fast action sequences.

This TV is not the best choice for dedicated home theater enthusiasts. The lack of local dimming, low HDR brightness, and basic audio make it a poor fit for a cinephile’s main viewing setup. Movie lovers should consider the TCL QM6K, QM7K, or Hisense U7 series instead.

Pros and Cons of the TCL Q77K

Every TV has strengths and weaknesses. Here is an honest look at what the TCL Q77K does well and where it falls short.

The biggest pro is the gaming feature set. A native 144Hz refresh rate, VRR support across all three formats, HDMI 2.1 bandwidth, and sub 6ms input lag make this one of the best gaming TVs under $500. No other TV at this price offers this combination.

The price itself is a major advantage. Starting under $300 for the 55 inch model and under $500 for the 75 inch model makes the Q77K accessible to almost any budget. The bundled Allstate warranty from Costco sweetens the deal even further.

QLED color enhancement produces vibrant, eye catching images for everyday content. Sports, YouTube, and streaming shows all look bright and colorful. Google TV provides a smooth and intuitive smart TV experience with access to thousands of apps.

On the downside, HDR performance is disappointing. Low peak brightness and no local dimming mean HDR content does not look much different from SDR. This is the biggest picture quality compromise.

Audio quality is below average. The built in speakers lack bass, surround effects, and overall power. Most buyers will want a soundbar. Wi Fi 5 instead of Wi Fi 6 is another minor drawback in 2026.

Viewing angles are acceptable but not great. The HVA panel improves on standard VA, but IPS panels still offer better wide angle performance. Large group viewing can be less than ideal.

Long Term Reliability and Warranty Coverage

The TCL Q77K benefits from Costco’s excellent warranty and return policies. Each purchase includes an Allstate 3 year protection plan bundled into the price. Combined with TCL’s standard 2 year manufacturer warranty, you get 5 years of total coverage.

TCL has improved its reliability reputation over the past few years. Early budget TCL models had mixed reviews for longevity. More recent models, including the Q77K, show better build quality and fewer reported defects.

Google TV receives regular software updates. This means your smart TV features stay current with new apps, security patches, and interface improvements. TCL has been consistent with pushing updates for its Google TV models throughout 2025 and into 2026.

The backlit remote uses standard batteries and is easy to replace if it fails. The power supply is internal, so there are no external power bricks to worry about. The HDMI ports and other connections use standard connectors that are durable with normal use.

Costco’s 90 day return window gives you plenty of time to test the TV in your home. If anything feels wrong during that period, you can return it for a full refund. This is one of the most generous return policies in the retail industry for electronics.

For a budget TV, the warranty coverage and return options make the Q77K a very safe purchase. You are protected against defects and can return it if it does not meet your expectations.

Final Verdict: Is the TCL Q77K Worth It in 2026?

The TCL Q77K delivers an incredible value for budget TV buyers in 2026. It packs gaming features that rival TVs costing two to three times as much. The 144Hz refresh rate, full HDMI 2.1 support, VRR across all formats, and ultra low input lag make it a standout choice for gamers.

Picture quality is adequate for the price. The QLED panel produces vivid colors and decent contrast. Everyday content looks good. However, the lack of local dimming and low HDR brightness hold it back from competing with Mini LED options.

Sound quality requires a soundbar upgrade for the best experience. HDR performance is a clear weakness. These are trade offs you accept at this price point.

If you are a gamer on a budget, the TCL Q77K is one of the best TVs you can buy in 2026. If you care more about movie quality HDR and audio, look at the TCL QM6K or Hisense QD7 instead. The Q77K knows what it is. It is a feature rich, gaming focused, budget friendly QLED TV that punches above its weight in the areas that matter to its target audience.

Frequently Asked Questions

Is the TCL Q77K good for PS5 and Xbox Series X gaming?

Yes, the TCL Q77K is an excellent choice for PS5 and Xbox Series X. It supports 4K at 120Hz, VRR, ALLM, and HDMI 2.1 on two of its four HDMI ports. Input lag is under 6 milliseconds in Game Mode. It was highlighted by users as the cheapest TV to enable all Xbox Series X features. Both consoles will run at their full potential on this TV.

Does the TCL Q77K have local dimming?

No, the TCL Q77K does not have local dimming. It uses a direct LED backlight without any dimming zones. This means the entire backlight operates at one brightness level. This affects HDR performance and can cause some blooming around bright objects on dark backgrounds. If local dimming is important to you, consider the TCL QM6K or QM7K.

Where can I buy the TCL Q77K?

The TCL Q77K is a Costco exclusive in North America. You can purchase it at Costco warehouse stores or on Costco.com. It is not available at Best Buy, Amazon, Walmart, or other major retailers in the United States. You need a Costco membership to purchase it.

What sizes does the TCL Q77K come in?

The TCL Q77K is available in five sizes: 55 inch (55Q77K), 65 inch (65Q77K), 75 inch (75Q77K), 85 inch (85Q77K), and 98 inch (98Q77K). All sizes share the same feature set including the 144Hz panel, HDMI 2.1 support, and Google TV smart platform.

Is the TCL Q77K better than the Samsung DU7200?

The TCL Q77K offers significantly better gaming features than the Samsung DU7200. The Q77K has a 144Hz refresh rate and HDMI 2.1, while the DU7200 is limited to 60Hz and HDMI 2.0. For gaming, the Q77K is the clear winner. The Samsung DU7200 may appeal to buyers who prefer Samsung’s Tizen smart TV platform and brand reputation for everyday non gaming use.

Does the TCL Q77K support Dolby Vision?

Yes, the TCL Q77K supports Dolby Vision, HDR10, HDR10 Plus, and HLG. It can receive and process all major HDR formats. However, due to its limited brightness of around 300 nits and lack of local dimming, the actual HDR experience is modest compared to brighter TVs with zone based dimming.
