[Breaking News] Beloved Dock Not Fully Compatible with Switch 2!? ― A Comprehensive Report on the Joys and Sorrows of the Dongii Portable HUB & VITURE Pro XR Mobile Dock

1. Introduction: Peripherals that were supposed to be the "victory of portability" become obsolete overnight?

As soon as the Nintendo Switch 2 was released on June 5, 2025, reports flooded Reddit and X (formerly Twitter) that the ultra-compact docks, which were popular for the original Switch 1, were no longer functioning. For portable gamers, "playing on a big screen in a hotel room" was synonymous with the small dock. However, timelines have been filled with chaos from the first day of release, with comments like "No video or charging with Dongii" and "VITURE Pro dock makes XR glasses go dark."theguardian.comreddit.com

2. What is the Dongii Dock HUB?

Launched on Kickstarter in 2019 and commercialized in 2020, the Dongii Dock HUB became a buzz as a "pocket-sized Switch dock." With a greedy design that fits HDMI 4K/60Hz, PD 65 W power supply, and USB-A×1 into a business card size, it gradually sold in Japan at mass retailers and fan events. The main specs are

• USB-C PD 3.0 (5 V–20 V / up to 65 W)

• HDMI 2.0 (4K60)

• Built-in Bluetooth 5.0 audio transmitter

• Weight approximately 134 g

making it the prime candidate for the "official dock (about 327 g) killer" as of 2020.broadwaylifestyle.com

3. What is the VITURE Pro XR Mobile Dock?

On the other hand, the VITURE Pro XR Mobile Dock is a gamer-oriented expansion device that, when combined with XR glasses, achieves a "virtual screen equivalent to 140 inches anywhere." It features a 20-hour battery and encodes USB-C/HDMI input into XR glasses video. In the Switch 1 generation, it was talked about as a "new experience without a TV."viture.com

4. The full picture of the "specification changes" on the Switch 2 side

The Switch 2 features two USB-C ports on the back and bottom, but a real-world test conducted by Tom’s Guide on the release day confirmed that "no DisplayPort Alt Mode comes out from USB-C." Nintendo continues to inherit the Mobility DisplayPort (MyDP) and requires a unique handshake with the dock. As a result,third-party USB-C → HDMI docks are uniformly "zero video." Furthermore, due to high-output negotiation using the PD 3.1 48 V rail, there is a tendency for power supply shortages with older 15 V/20 V chargers.tomsguide.comreddit.com

5. Troubles Encountered by Dongii Users

On the midnight of the release date, posts from users claiming to be Dongii users flooded X.

"#Switch2 #Dongii screen is pitch black. LED won't light up. Switched back to the original dock and it worked immediately. Time to buy a new one... (crying)"
"The Dongii left plugged in the company's meeting room turned into a paperweight, lol"

Similar threads also gained traction on Reddit, with posts like "Switch 2 consumes nearly twice the current of the old dock. Cheap docks blow the FUSE" and "I've already switched to Genki Dock" appearing frequently.reddit.comreddit.com

Specific Symptoms

• When inserting the Switch 2 “remains in handheld mode” → Screen displays on the console / HDMI unresponsive

• AC power lamp does not light up / no change in charging icon

• Dongii repeatedly resets after a few seconds (suspected internal overcurrent protection)

Some users reported that "switching to a 65 W→100 W compatible GaN charger made it work," but reproducibility seems low.

6. The Tragicomedy of VITURE Pro Users and Firmware Updates

VITURE's official Reddit account (VITURE-Slash) promptly announced "Switch 2 compatible firmware released". However, even after the update, voices saying "It doesn't display when directly connected to the console. Ultimately, a multi-stage connection via 'original dock→HDMI→mobile dock' is necessary" were predominant, leading to a thread with over 1000 comments.reddit.com

Comments like "Why did Nintendo disable video on both USB-C ports?" and "My bed theater plan with Switch 2 is ruined" along with meme images (a tombstone engraved with Dongii) were rampant.

7. What is Happening Technically: USB-PD 3.1/MyDP Protocol Issues

• PD 3.1 EPR (Extended Power Range) 48 V/5 A

  • The Switch 2 console demands up to 210 W when docked, achieving SoC overclocking and 4K60 output. An unusually high power design even in the USB domain.

• Mobility DisplayPort (MyDP)

  • MyDP has fewer DCPins (AUX＋HS), making direct output with ALT-DP dongles impossible. This has been carried over since the Switch 1 era.

• Proprietary authentication chip

  • The dock internally fakes EDID to activate HDMI PHY. For third parties to reverse engineer, modifications on the SoC FW side are necessary.

As a result, third-party docks

1. Fail to negotiate high power → Reboot due to power shortage

2. Lack of MyDP signal → Unable to switch to video output mode, remaining on the main screen

9. Manufacturer/Community Response and Future Outlook

10. Conclusion—Is the "Era of Small Docks" Ending?

• Switch 2's design is "inseparable from the official dock"—steering towards further solidifying the portable⇆stationary hybrid.

• Small docks like Dongii/VITURE require significant modifications──not only simple PD voltage support but also MyDP→HDMI conversion and proprietary certification measures are essential.

• The initial reactions on social media were a storm of disappointment and self-deprecating jokes, but now that Genki and the DIY community have started moving, there is a possibility that in 1-2 years, "super compact docks compatible with Switch 2" will once again dominate the market.

  "It was the same uproar with Switch 1 in the beginning. People don't learn, but technology advances," said a veteran modder.

Will officially licensed products dominate the market, or will the wisdom of the community break down the barriers? In the summer of 2025, the battle among portable gamers has only just begun.
