How to Upscale Nintendo Switch to 4K

The Nintendo Switch outputs natively at up to 1080p resolution when docked. For gamers with 4K televisions, getting the most from the Switch’s graphics requires upscaling to ultra HD 4K. In this guide, we’ll examine solutions for transforming Switch visuals to glorious 3840 x 2160 resolution.


While not as powerful as new consoles like the PS5 and Xbox Series X, the Switch’s first party games still sport beautiful, clean art styles that can benefit from 4K displays when properly upscaled. Options range from standalone upscaler boxes to 4K HDMI cables.

When selecting a 4K upscaling solution for Switch, key factors to consider include:

  • Support for 1080p 60fps input and 4K 60fps output
  • Lag-free, game optimized video processing
  • HDR preservation from Switch games that support it
  • HDMI 2.1 capability for 4K/120Hz

We’ll recommend some excellent 4K upscalers proven to work great with the Nintendo Switch while keeping lag to an absolute minimum. Let’s boost Switch gaming to ultra high definition 4K!

Key Takeaways for 4K Switch Upscaling

  • Standalone upscaler boxes like the mClassic provide simple 4K upscaling, but cost over $100.
  • Specialty HDMI cables integrate upscaling into the cable itself for cheaper plug-and-play 4K conversion starting around $50.
  • Ensure minimal input lag – critical for fast action Nintendo games. Avoid post-processing effects.
  • HDMI 2.1 enables 4K/120Hz for extra fluidity. Some upscalers still max out at 4K/60Hz.
  • Enabling Game Mode on your 4K TV reduces display latency for best experience.
  • Clean 2D games like Mario Kart 8 and simple 3D games upscale wonderfully. More complex 3D titles fare worse.

Buyer’s Tips

  • Weigh plug-and-play cables vs standalone boxes – both integrate upscaling seamlessly.
  • Research input lag for real world game testing before purchasing when possible.
  • HDMI 2.1 enables 4K/120Hz for future console updates and reduces input lag.
  • Cleanly drawn first-party games fare best upscaled. Complex 3D games can look over-sharpened.


Does the Switch support 4K natively?

No, the original Switch model’s Tegra X1 SOC maxes out at native 1080p output when docked. The 2021 OLED model also remains 1080p native. Mods or upscalers are needed for 4K.

Is 4K worth it for Switch gaming?

4K shines best on clean 2D games like Mario Kart 8 thanks to sharp pixels and lines. Complex 3D games like Breath of the Wild are more debatable for upscaling benefits. HDTVs still look great.

What’s better for 4K gaming – cables or adapters?

Both integrate upscaling well. Adapters offer more features and tweaking but are expensive. Quality 4K HDMI cables provide a cheaper plug-and-play solution. Try an affordable cable first.

Will upscaling 4K reduce Switch battery life?

No, upscaling only occurs when docked for TV/monitor gaming. The native handheld resolution remains unchanged. Upscalers only impact docked gaming.

Is 4K upscaling possible on the Switch Lite?

Unfortunately no – since the Switch Lite is handheld only, external upscalers or cables can’t tap into its video output like they can via the dock. The Lite remains locked at 720p max.


While the Switch doesn’t natively output 4K, external upscalers can quadruple its docked 1080p resolution to ultra sharp 3840×2160 4K when connected to compatible TVs and monitors.

Both plug-and-play cables and standalone upscaler boxes integrate 4K conversion seamlessly while adding minimal input lag. This allows you to enjoy Nintendo’s gorgeous first-party games at up to 4K 60fps on supported displays for added clarity and crispness. 4K gaming gives the Switch an upgraded look!
