UltraHDMI
UltraHDMI
This is an internal mod requiring fine soldering of a flex cable to the console's digital video bus. Mistakes can ruin the board. Have an experienced installer do it if you are not confident.
UltraHDMI was the first kit to give the Nintendo 64 a true digital HDMI output. It taps the console's internal digital video signal before it ever becomes analog, so the image is pristine, free of the noise that affects composite, S-Video, and even RGB.
- Source the kit. UltraHDMI is discontinued and was produced in limited runs, so units are scarce and command high prices on the secondhand market.
- Install the board. Mount the kit inside the console and solder its flex connection to the digital video lines, then route the HDMI port out through a cut in the shell.
- Configure output. UltraHDMI offers an on-screen menu with scaling modes, scanline effects, and de-blur, all adjustable to taste.
- Verify. Boot a 240p test ROM to confirm clean output, correct aspect ratio, and that the de-blur toggle behaves as expected.
Feature highlights
The kit's strengths are its flexible scaler, optional scanlines for a CRT look, and a built-in de-blur control that removes the soft filter many games apply.
Because it is no longer made, most people now choose the PixelFX option instead. UltraHDMI remains excellent where you can find one. discontinued
