I am a classical musician (violist) with 20 years of professional experience in orchestra and chamber music. For years, I have been using all kinds of large and very large tablets as part of my work as a musician.
I also have a degree in computer science, and I have always been interested in computer hardware. This article is therefore a summary of the hardware and practical side of using very large tablets.
I spent my school years in France, and this article must be riddled with spelling and grammar mistakes, for which I apologize. Feel free to send me any corrections!
Verdict: It's the largest, but not the best.
Since modern reviews start with the conclusion, here are my final thoughts: The Meswao B3 Pro is not a very good tablet. Its display would be ideal for video streaming, but it has no Widevide L1 certification, which makes it suboptimal for HD streaming of copyrighted content (Netflix, Amazon Prime, HBO, etc.). It’s also super heavy!
Its outdated Helio G99 processor is fine for most users, but too slow for gaming or anything demanding. Meswao has no clear policy regarding Android upgrades or security updates, and they have been known for not pushing out security updates in the past.
On the other hand, the Meswao B3 Pro is unique and has no direct competitors. Its 15.6-inch display is much larger than what Apple (max. 13 inches) and Samsung (max. 14.6 inches) have to offer.
Despite its 16:9 aspect ratio, the area of the display is huge, representing 111% of a Letter-size sheet of paper. It is 10 % larger than the display area of the Samsung Galaxy Tab S11 Ultra and 28 % larger than of the iPad Pro 13-inch display.
If you want a high-quality, future-proof tablet with security support and Android upgrades, skip the Meswao MES-B3 Pro. But if you need the biggest tablet available and can compromise on processing power, video streaming quality, security updates, and more, then go for it!

What is the difference between the Meswao B3 and the B3 Pro?
The original Meswao MES-B3 was released in April 2024. In August 2025, Meswao quietly upgraded its largest tablet and added “Pro” to its name.
Unfortunately, the hardware was not upgraded except for the battery, which charges at 30 watts on the new Pro model instead of 15 watts on the old one.
This was a needed upgrade because the charging time dropped from six hours on the non-Pro model to three hours on the Pro version. But of course, it’s definitely not enough to merit the “Pro” label.
3. Case - A huge screen makes for a huge tablet
The Meswao MES-B3 Pro is available in the colors Midnight Black and Starlight Silver. It is exactly 10 mm (0.39 inches) thick, which is almost twice as thick as the Samsung Galaxy Tab S11 Ultra and the iPad Pro 13-inch (both 5.1 mm or 0.20 inches thick). Without a case, it’s fine, but with a case, it becomes super-thick.

The bezels around the screen are large: they measure 12 mm (0.47 inches) on the top and bottom and 10 mm (0.39 inches) on the sides when held in landscape position. These large bezels make the whole tablet bigger.

Weight
The Meswao B3 Pro is the heaviest tablet I’ve ever had in my hands. It’s almost twice as heavy as the Samsung Galaxy Tab S11 Ultra (which costs four times as much).
However, it’s only slightly heavier than entry-level 14-inch tablets, such as the Callsky Ctab 14 and the Doogee Tab E3 Max (992 g or 2.19 lbs for the latter).

4. Display
The Meswao B3 has a 15.6-inch IPS screen with a 16:9 aspect ratio, meaning the screen is extremely wide. It measures 13.60 inches (34.54 cm) long by 7.65 inches (19.43 cm) high. In portrait mode (hold vertically), it is narrower than a sheet of paper, but much taller.
This huge screen makes it possible to display text with greatly enlarged characters, which is useful for people with poor eyesight or when viewing the screen from a distance. However, the relatively low resolution of 1920 x 1080 pixels on a screen this size results in a pixel density of only 141 ppi (pixels per inch). This means that the pixels on the screen are visible, and the characters are not very sharp.
For comparison, the pixel density of all Apple iPads is 264 ppi, while it varies between 239 and 266 ppi on large Samsung tablets (depending on the model), resulting in sharper displays.
The Meswao MES-B3 Pro’s extra-wide screen can be especially useful for users who benefit from displaying text in larger sizes. When using a Bluetooth keyboard, there is enough vertical space for a few paragraphs. Photo: large-screens.com
Without a Bluetooth keyboard, however, the on-screen display takes up a lot of vertical space. Due to the 16:9 aspect ratio of the screen, there is only little room for the actual content! Photo: large-screens.com
It is not possible to wake the tablet by double-tapping the screen. I use this feature all the time on my phones and tablets and regret its omission on the Meswao.
4.1 Screen brightness: sufficient for indoor use.
With a maximum brightness of 350 nits (cd/m²), the Meswao MES-B3 Pro is on par with other entry-level and mid-range tablets. This brightness level is sufficient for indoor use and for outdoor use in the shade on days with average sunlight.
However, it is not bright enough for sunny summer days outdoors (at least 600 nits would be required, even in the shade). For comfortable use in direct sunlight, the tablet would need to reach 1000 nits.
I speak from experience, because as a musician, I use tablets to read sheet music. When I perform outdoors in direct sunlight, the tablet must remain readable and not overheat!

4.2 Streaming videos on the world's biggest tablet screen
With its enormous 15.6-inch display, it’s easy to see why the Meswao B3 Pro would be ideal for watching videos. To an extent, that’s true; movies are much larger and more comfortable to watch on this tablet than on any other large tablet.
Initially, I thought the 16:9 aspect ratio would look too wide or “elongated”, but that was before I tried movies in the Cinemascope (or DCI Scope) format of 2.39:1. As the picture below shows, there are still black bars on the top and bottom of the screen, and the movie uses only 1920 x 804 pixels (out of 1920 x 1080).

Having used the best tablets from Samsung (the Galaxy Tab Ultra series) and Apple (the 12.9- and 13-inch iPad Pros) for years, I expected the screen quality of the Meswao B3 Pro to be much worse. In reality, it’s OK for movies, but with the following caveats:
- The display is glossy and highly reflective. Any window or lamp causes glare.
Unfortunately, the Meswao 15.6-inch tablet has a glossy display that is prone to reflections, as can be seen in the picture. (By the way, this is a screenshot from the hilarious series “Extraordinary”, which is available on Hulu, Disney+, and Apple TV.) Photo: large-screens.com
- There are sometimes drops in streaming quality for a few seconds. Most users, including children, won’t notice, but if you want consistent, high-resolution videos, this tablet is definitely not for you.
- The Meswao B3 Pro does not have Widevine L1 certification. This means that copyrighted content from streaming platforms (including Netflix, HBO, Amazon Prime, …) may only be shown in SD and not in HD or 4K.

Meswao MES-B3 Pro: Performance
The Meswao MES-B3 is powered by the relatively old MediaTek Helio G99 (MT6789) processor, which was released in Q3 2022 and built on a 6nm process. While it’s decent for basic tasks like streaming or browsing, it’s not made for heavy gaming or multitasking. Here are some comparisons to pricier, large-screen Apple and Samsung tablets:
- The Apple M3 processor in the iPad Air 13 is almost six times faster than the Helio G99.
- Qualcomm’s Snapdragon 8 Gen 2, found in the 2022 Galaxy Tab S9 Ultra, performs roughly three times faster.
- Staying within MediaTek’s lineup, the Dimensity 9400+ (found in the Galaxy Tab S11 series) is over four times faster.
When compared to entry-level tablets, however, the Meswao B3 is average, and loads of tablets use the same SoC. For most users, the performance will be just fine.

Four speakers, poor sound quality
The Meswao B3 Pro performs surprisingly poorly in terms of speaker quality. Although there are four well-positioned speakers, they are really anemic, and two larger (and better) speakers would have been preferable.
As the picture below shows, the speaker holes in the Meswao’s case (at the bottom of the pile) are unusually small, and the resulting sound is accordingly weak.

The treble is overly prominent, and the sound quality is generally subpar. Additionally, the maximum volume isn’t very high. It should be fine if you’re watching a movie alone in a quiet room. However, forget about listening with friends, in a noisy environment, or while cooking!
To fix this problem, I strongly recommend using Bluetooth speakers or headphones.
Is this really the word's biggest tablet?
Yes! The Meswao B3 Pro is definitely the largest tablet available in 2025.
In the past few years however, three foldable Windows tablets have been released, but they were extremely expensive and heavy:
- The Lenovo ThinkPad X1 Fold Gen 2 has a 16.3-inch display when unfolded. It was released in 2024 with an MSRP of $2,500, but it is no longer available from Lenovo and has no successor.
- The Asus Zenbook 17 Fold OLED has a slightly larger, 17.3-inch display. It was released in December 2022 with an MSRP of $3,500 in the US, and it is no longer available.
- The HP Spectre Foldable 17 has a 17-inch display when unfolded. It launched in October 2023 at a price of $5,000, but it has since been discontinued without a successor.
Apple has reportedly been working on a foldable iPad (or iMac) with a 20.3-inch display, but the release has been postponed to 2027 or 2028 – or even cancelled.1
