Best HDMI Upscaler for Nintendo 64

The Nintendo 64 natively outputs low resolution 240p composite video. On HDTVs, this results in a blurry, pixelated image that hampers gameplay. A dedicated HDMI upscaler can transform N64 visuals into crystal clear HD. In this guide, we’ll recommend the best upscalers to maximize your N64 experience on modern televisions.


Since the N64 pre-dates HD video, connecting directly to a modern HDTV via composite cables produces mediocre results. The best HDMI upscalers process the 240p signal digitally to output crisp 720p or 1080p resolution over HDMI while adding minimal lag.

When selecting an upscaler for N64, key factors include:

  • Lagless processing optimized for real-time gaming
  • Native 240p input support
  • HDMI output up to 1080p

We’ll suggest popular upscalers with proven lag-free performance when paired with the N64. Let’s revisit classics like Super Mario 64 and Ocarina of Time in stunning high definition!

Key Takeaways on N64 Upscalers

  • The RetroTINK 2X line are the go-to choices for crystal clear low lag upscaling.
  • Make sure any scaler accepts 240p composite input to avoid deinterlacing artifacts.
  • 1080p output provides sharpest results, but even 720p is a massive leap over composite.
  • Advanced options like the 5X allow customized firmware and resolutions.
  • Simulate authentic scanline looks using the 2X’s range of available filters.
  • For under $100, the RetroTINK 2X Pro is hard to beat for no fuss N64 upscaling.

Does the N64 support HDMI?

No, the N64 pre-dates HDMI and outputs 240p composite video only. An external upscaler box or mod is required to convert the signal into HDMI.

What’s the best cable to use with an N64 upscaler?

To maximize quality, use the original S-Video cable or HD Retrovision component cables. But even basic composite works well with good scalers like the RetroTINK 2X.

Will N64 games look good scaled to 1080p?

Even with upscaling, the N64’s heavily pixelated 3D graphics won’t look as clean as modern 1080p titles. But they remain highly playable and the image quality boost over composite alone is massive.

Do upscalers add input lag for N64 gaming?

Quality gaming focused upscalers like the RetroTINK units add negligible lag – under 1ms. Gameplay feels perfectly responsive still despite the signal conversion.

What about cheap generic HDMI adapters?

Generally avoid cheap no-name adapters. They often lag, process 240p improperly, degrade video, and fail to match the quality of respected scaler brands focused on retro gaming.


HDMI upscalers restore crispness and clarity to N64 games on today’s HDTV displays. When fed an S-Video or composite signal, they output gorgeous 720p or 1080p digital video over HDMI.

Options like the RetroTINK 2X provide near lag-free upscaling that makes games feel responsive while looking clean. Revisit N64 classics like never before!
