The Vizio V705x-J03 is a 70-inch 4K TV from Vizio’s 2021 entry-level V-Series, and in 2026 it makes sense only at a low used or clearance price. It earned a following for putting a huge screen, Dolby Vision, and low input lag within reach of tight budgets. This Vizio V705x-J03 review explains what the TV does well, where it falls short, what has changed at Vizio since 2021, and which current 70- to 75-inch TVs are worth comparing before you buy.
Quick verdict: The V705x-J03 offers a big, sharp picture, wide high dynamic range (HDR) format support, and responsive gaming for the money. It’s dim, though, and it has no local dimming, so HDR looks flat and bright rooms wash it out. It makes sense only at a low used or clearance price; newer budget TVs offer much more. Check the Vizio V705x-J03 price on Amazon.
Key takeaways
- What it is: A 70-inch 4K TV from Vizio’s 2021 V-Series with a full-array backlight, no local dimming, and a 60 hertz (Hz) panel.
- Price: It launched at about $700, while Vizio’s 2026 75-inch Mini LED Quantum was listed at about $498 at Walmart (fall 2026). Prices change often.
- Main strength: Gaming, with about 13.7 milliseconds of input lag in Tom’s Guide’s testing, plus variable refresh rate (VRR) and auto low latency mode (ALLM).
- Main weaknesses: Tom’s Guide measured a peak of only about 243 nits, so HDR looks flat, bright rooms wash out the picture, and viewing angles are narrow.
- Status: The TV is discontinued, Walmart now owns Vizio, and the 2026 Mini LED Quantum lineup is the natural upgrade.

Specs come from Tom’s Guide’s V-Series review, RTINGS, and the V705-J03 spec sheet. The V705x-J03 is a retailer variant of the V705-J03 and shares its core hardware.
What’s changed since the V705x-J03 launched
Vizio has replaced the 2021 V-Series several times, and the company itself has changed hands. Walmart bought Vizio at the end of 2024, and Vizio TVs now sell mainly through Walmart. Vizio’s smart platform, once called SmartCast, now goes by Vizio OS on current models.
Vizio’s newest big-screen budget pick is the 2026 Mini LED Quantum lineup. The 75-inch model (VQM75C-10) adds quantum dot color, a Mini LED backlight with local dimming, and 1080p gaming at up to 120 frames per second, and it was listed at about $498 at Walmart when we checked. Prices change often, so treat that figure as a guide. Vizio also still sells its standard Quantum 4K QLED in 75 inches. You’ll find fewer 70-inch models across the industry today, as most brands have moved to 75 inches as the step above 65.
Design and setup
The V705x-J03 has thin bezels on three sides and a plain, plastic build that keeps costs down. The two feet sit near the outer edges of the screen and don’t adjust, so plan for a TV stand or console close to the TV’s roughly 62-inch width. If you don’t have furniture that wide, wall mounting is the easier route.
The TV uses a VESA 400 x 200 pattern and weighs about 53 pounds, so most mounts rated for 70-inch TVs will fit. Many of the picks in our guide to the best TV wall mounts for 65-inch TVs also support 70-inch sets; just check the VESA pattern and weight rating. You can also shop wall mounts for 70-inch TVs on Amazon.
Picture quality
In a dark or dim room, the V705x-J03 looks good for its price. Its contrast is solid for a budget liquid crystal display (LCD) TV, blacks look reasonably deep, and 4K content appears sharp on the big screen. Tom’s Guide measured strong color accuracy in standard dynamic range, with 97.8% coverage of the Rec. 709 color space used for high-definition (HD) content.
Brightness is the weak spot. Tom’s Guide measured a peak of about 243 nits, which is low for HDR. Dolby Vision and HDR10+ support means the TV can read the extra information in HDR content, but it can’t display highlights with much punch. It also lacks local dimming, so it can’t darken parts of the screen independently; our explainer on what local dimming is covers why that matters. In a bright living room, the picture looks washed out, and viewing angles are narrow, so colors fade for people sitting off to the side.
Upscaling and Active Pixel Tuning
Vizio’s IQ Active processor upscales HD content to 4K, and the results look clean for a budget set. Vizio’s Active Pixel Tuning adjusts brightness, color, and contrast at the pixel level to sharpen detail. It works through processing, not dimming zones, so it doesn’t replace true local dimming.
Gaming performance
Gaming is one of the V705x-J03’s strengths for its class. It supports VRR to reduce screen tearing and ALLM, which switches the TV to its low-lag game mode automatically when a console starts a game. Tom’s Guide measured input lag of 13.7 ms, which feels responsive for casual and competitive play. The catch is the 60Hz panel: you can’t play at 120 frames per second, which newer budget TVs now offer. Our guide to 60Hz vs. 120Hz TVs explains the difference.
Smart features and remote
SmartCast includes the major streaming apps, WatchFree+ (Vizio’s free, ad-supported live TV service), Apple AirPlay 2, and Chromecast built-in, so you can cast from iPhones and Android phones alike. It also works with Amazon Alexa, Google Assistant, and Apple HomeKit devices. Tom’s Guide found the interface a bit slow and noted that some apps, such as ESPN+ and FuboTV, were missing at the time of its review, so check that your must-have apps are available.
Vizio’s spec sheet lists the XRT260 voice remote for this model, and Tom’s Guide’s review unit included a voice remote that can search for content and open apps. If you buy used, confirm which remote comes with the TV, since the Vizio mobile app can also stand in as a remote.
Sound
The TV has two 10-watt speakers with DTS Virtual:X, which simulates surround sound. Tom’s Guide found the audio adequate for dialogue but lacking bass and without Dolby Atmos. A big screen deserves bigger sound, so a budget soundbar is a worthwhile add-on.

Who should buy the Vizio V705x-J03?
Buy the V705x-J03 only if you find it used or on clearance for well under the price of a new 75-inch budget TV, and you mostly watch in a dim room. It suits a basement, game room, or second living room where screen size matters more than HDR punch. Skip it if your room gets lots of daylight, if you want vivid HDR, or if you play games at 120 frames per second. A current Mini LED model from Vizio, TCL, or Hisense will look much better for not much more money.
Frequently asked questions
Is the Vizio V705x-J03 still sold?
No, Vizio no longer sells the V705x-J03 new. It’s a 2021 model, and you’ll mostly find it used, refurbished, or as leftover stock. Vizio’s current 75-inch models, such as the 2026 Mini LED Quantum, replace it.
Does the Vizio V705x-J03 have local dimming?
No, the Vizio V705x-J03 doesn’t have local dimming. It has a full-array backlight, but it can’t dim zones independently. Vizio’s Active Pixel Tuning is image processing, not local dimming.
Is the Vizio V705x-J03 good for gaming?
The Vizio V705x-J03 is good for casual gaming at 60 frames per second, with low input lag, VRR, and ALLM. It can’t run games at 120 frames per second because the panel is limited to 60Hz.
What wall mount fits the Vizio V705x-J03?

Final verdict
The Vizio V705x-J03 delivered a lot of screen for the money in 2021, with broad HDR support, good color accuracy, and responsive gaming. Its low brightness, lack of local dimming, and 60Hz panel hold it back today, and new 75-inch Mini LED TVs now cost less than this TV did at launch. Grab one only at a bargain price; otherwise, step up to a current model. Check the current Vizio V705x-J03 price on Amazon.
