HDMI Cable for N64, Support 16:9/4:3 Conversion, N64 to HDMI Converter, Composite with N64/GameCube/SNES https://www.amazon.com/dp/B081L9BQNJ/ref=cm_sw_r_apan_glt_fabc_8WZCAS7JFM3NFYWKAD4N?_encoding=UTF8&psc=1

The crappy thing is that it registers on the TV as "1080p" .

If it registered as 1080i I feel like the TV would automatically deinterlace it.

I personally use just a cheap “N64 to HDMI adapter” and it works well enough, I just can’t vouch for the sound since my monitor doesn’t have speakers, but the video works like you would expect.
