Yaber K3 projector review: an affordable smart projector that delivers good sound but sub-par picture quality

The Yaber K3 is a budget smart projector that offers 1080p resolution, 1600 ANSI lumens brightness and built-in access to streaming services such as Netflix and Disney Plus. While it delivers good sound and a Google TV smart interface for cheap, its picture quality is inconsistent and there are several other issues with it as well.

A smart projector such as the Yaber K3 for $599 / £569 is a tempting prospect, especially when it can light up 40-200-inch screens. And while it’s not as well featured as the best projectors, built-in Wi-Fi and decent built-in speakers are hard to find at this price range. But some of the K3’s other main features such as its auto keystone correction and processing are sluggish and often frustrating to use. Gamers will also be better off looking elsewhere.

The K3’s picture quality is a very mixed bag. It displays natural colors and solid enough detail at times and puts in a decent showing with sports. But contrast is weak and black levels are washed out. The K3’s picture quality was never going to compete with the best 4K projectors, but even compared with some of the best portable projectors, such as the Samsung Freestyle Gen 2, the K3’s picture struggles.

Where the K3 excels is its sound, as the built-in JBL speakers are punchy and powerful, especially at this budget price range. While one of the best soundbars is still recommended, some won’t find the need to add one, especially for casual viewing.

Fundamentally, the Yaber K3 is for those who are looking for a smart projector at an affordable price for the occasional movie night. While it packs as much as it can into its budget-friendly frame, it’s not quite the bargain budget gem it could have been.

Yaber K3 projector review: Price & release date

• Price: $599 / £569 (roughly AU$942)
• First available: September 2024

The Yaber K3 is a 1080p smart projector that follows on from Yaber’s K2 series. The K3 is priced at $599 / £569 (roughly AU$942 with direct exchange), putting it at the budget end of the projector spectrum in direct competition with portable projectors such as the Samsung Freestyle Gen 2 (also a 1080p smart projector) which has a standard price of $749 / £649.

Since its release in September 2024, there have been some discounts on the Yaber K3, with prices falling to $499 / £465 during sales events. This is similar to the discounts the Samsung Freestyle receives, as it’s regularly priced at $549 / £499 during sales events.

Yaber K3 projector review: Design & features

• 1600 ANSI lumens
• Google TV smart interface
• Nice fabric grill but bulky elsewhere

The Yaber K3’s fabric front grill gives it a slightly more premium appearance than its budget price would suggest, but elsewhere it appears a little plain and oddly bulky looking. It measures 11.4 x 12.7 x 6.1 inches (290 x 3232 x 154mm) and requires a mains power supply with no battery options. There’s also a noticeable amount of fan noise after extended viewing periods.

The K3 has a specified 1080p resolution and 1600 ANSI lumens brightness. It has a 1.2:1 throw ratio and fits screens from 40-200 inches. Auto and manual keystone adjustment and object detection count among its features, but I generally found that auto keystone was frustrating and often didn’t calibrate correctly to the Optoma 80-inch portable screen I was using for my tests. Manual keystone correction can only be done via the Yaber homepage and not while watching content – another aspect I found frustrating.

Despite its budget price, it uses Google TV as a smart TV interface. This provides access to some of the best streaming services including Netflix, Prime Video and Disney Plus. For connections, it has two HDMI ports, one USB-A port, a 3.5mm audio output and Bluetooth wireless.

The K3 has a surprisingly robust built-in speaker system for such a budget projector, with dual 15W JBL speakers totaling 30W of power.

No gaming features are included on the K3. For those looking for a gaming projector, you’re better off with something like the BenQ X300G.

Yaber K3 projector review: Picture & sound quality

• Inconsistent picture quality
• Decent enough colors
• Surprisingly punchy sound

For my testing, I used an Optoma 80-inch, 1.0 gain matte white projection screen. I first began by taking brightness measurements using a colorimeter, and the K3 yielded results of 109 nits and 93 nits in Standard and Natural picture modes respectively, putting it above 4K portable projectors such as the LG CineBeam Q (which yielded 60 nits in Filmmaker Mode).

Moving on to critical viewing, I first looked at an HD stream of Star Wars: The Last Jedi on Disney Plus, focusing on the throne room fight scene. Colors were natural enough, but they lacked any sort of dynamic punch. Characters’ skin tones also appeared washed out, even in the most accurate Natural picture mode (though there wasn’t a great deal of difference between the various picture modes). The same was true for La La Land on Blu-ray, which showed natural colors but also inaccurate textures, although in some scenes details were more refined than I’d anticipated.

Next, I watched a Blu-ray of The Batman to test black levels and contrast. While mostly acceptable, I found some scenes difficult to watch due to limited brightness (namely the opening crime scene investigation) even in blacked-out viewing conditions. In brighter scenes, details were clear and accurate enough, but there was a gray wash over the screen and textures still appeared fuzzy.

One area where the K3 did well was with sports. Watching soccer matches in Sports mode, the action was smooth and accurate enough that the games were watchable, though it won’t beat more premium projectors.

While the K3’s picture is average, its built-in sound is surprisingly good. Equipped with a JBL speaker system totaling 30W of power, the K3’s sound is punchy, detailed and clear. Watching the Batmobile chase sequence in The Batman, the sound of swerving cars was accurately presented, with a strong sense of direction. The rumble of the Batmobile’s engine had a hefty amount of bass and plenty of power, especially for small built-in projector speakers.

Even La La Land’s dynamic, jazzy score was presented with real clarity, with a good balance between the horns, strings and vocals throughout. While the JBL speaker’s soundstage is limited by its size, it’s still surprisingly effective for a built-in speaker at this price range.

• Picture and sound quality: 3/5

Yaber K3 projector review: Value

• Smart projector for a budget price
• Cheaper than most portable projectors
• Overall performance is frustrating

The $599 / £569 Yaber K3 is good value for those looking for an affordable projector that provides access to streaming services via the Google TV smart platform. It isn’t going to beat more premium projectors and may even struggle against some of the best portable projectors, but for those looking for a casual projector, the K3 is a budget-friendly option.

Unfortunately, shortcomings in the K3’s picture quality and some frustrations with setup such as keystone correction hold it back from being a budget gem. You’ll have to make some sacrifices, particularly with sound, on other portable projectors such as the Samsung Freestyle Gen 2, but the Freestyle is likely to give you a more consistent experience for a similar price.

How I tested the Yaber K3 projector

• Tested with an Optoma 1.0 gain, matte white 80-inch screen
• Tested using Blu-ray, streaming sources
• Measurements taken using Portrait Displays’ Calman calibration software

To test the Yaber K3 projector, I first used high definition and standard definition sources including Blu-ray and streaming. I tested the K3’s picture quality, analyzing color, contrast, black levels, detail and motion. I also evaluated its built-in JBL sound using the same reference scenes from movies and TV shows.

I used a colorimeter, test pattern generator and Portrait Displays’ Calman color calibration software to record measurements for brightness, contrast ratio and color and grayscale accuracy.

The projector was primarily tested in pitch-black conditions in our testing room at TechRadar and also in full ambient light settings to see how it handled brighter viewing environments.
