Duoone OLED Review: Expanding Nintendo Switch Multiplayer and DS Gameplay with Innovative Clamshell Monitors

Duoone OLED Clamshell Monitors: Transforming Nintendo Switch Multiplayer and DS Gameplay The Nintendo Switch has consistently inspired innovative hardware adaptations, and the Duoone OLED is among the latest to capture the attention of gamers seeking expanded multiplayer experiences and dual-screen nostalgia.

Developed with on-the-go convenience and Nintendo Switch connectivity in mind, the Duoone OLED monitors draw clear inspiration from the iconic Nintendo DS, bringing fresh potential for big-screen, portable DS-style play. Unveiled in early 2025, the Duoone OLED comes in two primary models: the 'Span' and the 'Fold'.

Both configurations consist of dual OLED monitors designed to plug directly into the Nintendo Switch, effectively adding two additional high-quality screens for enhanced gameplay sessions.

The key distinction between the two models lies in their configuration: the 'Fold' features a traditional clamshell design reminiscent of the Nintendo DS, while the 'Span' can extend an image seamlessly across both monitors, offering versatile use cases for different gaming setups. Hands-On Impressions: Design and Functionality In a hands-on review, Alex, a veteran games journalist, evaluated both the Span and Fold variations, testing their integration with the Nintendo Switch across various scenarios.

While the product’s official website features numerous examples—peppered with AI-generated promotional images—real-world performance proved to be more nuanced. During testing, setting up the Duoone OLED monitors required navigating some fiddly steps.

Users may find the initial configuration process, missing features, and high retail price to be hurdles to effortless gameplay.

However, the monitors’ unique design did deliver expanded real estate for multiplayer sessions, and, most notably, enabled dual-screen emulation.

Alex successfully ran titles such as Project Rub and Super Mario 64 DS, enjoying these games on a pair of vibrant OLED displays—an experience unmatched by any official Nintendo peripheral to date. Potential and Positioning in the Gaming Hardware Market The Duoone OLED establishes itself as a niche, yet genuinely innovative, accessory for Nintendo Switch owners interested in both multiplayer versatility and DS-era experiences.

Although some functional and setup challenges remain, the hardware demonstrates the lasting impact of Nintendo’s legacy, paving the way for more creative hardware solutions in the hybrid console space. As of February 2025, the Duoone OLED has yet to achieve mainstream adoption, but its ambitions have sparked conversation among Nintendo fans and hardware enthusiasts alike.

For those seeking to amplify their Nintendo Switch sessions or relive classic DS gameplay in a modern format, the Duoone OLED offers a tantalizing—if imperfect—glimpse into what’s possible with third-party innovation.
