HDMI Output

Modern TVs may not have component/composite inputs, may have poor internal analog to digital converters and/or you may prefer to connect your Xbox via HDMI.

Fully digital

By tapping directly into the digital signals from the GPU you can skip the on-board encoder. This is useful on a 1.6 Xbox due to video issues and arguably gives the cleanest picture of any solution on any version of the original Xbox, since it skips any digital-to-analog, analog-to-digital conversion and signal interference on analog cables/connectors. However, this solution will also require the most soldering and is one of the most expensive solutions.

OpenXHD is a work-in-progress open source project based on the unfinished work of Ryzee119 (from December 5th, 2023) for an all digital HDMI solution.

The only currently available retail project is not listed here due to legal threats from the manufacturer^[1].

Internal converters

Electron Shepherd LLC offer ElectronAnalog which is a module that takes the place of the consoles port to output a HDMI signal. It does not provided internal scaling of the image.

Plug & play converters

Another option to use HDMI is to use a 'plug & play' adapter. The pro's of this is that there are a lot of adapters available both cheaper and even some high end ones, however none will bypass the on-board encoder as they all use the analog output on the back of the device.

This solution requires no soldering and has a broad range of quality and price.

Comparison

There are a lot of adapters available and the most known/branded ones are added to this list.

Other options include "Kaico", "Pound", "Hyperkin", or modding a "Wii2HDMI", however these are more for convenience as for signal quality and will be beaten by a decent component cable with an ADC adapter.^[3]

One special note regarding the "Pound" adapter is that for certain revisions of the Xbox, it's better to use the externally powered cable as the onboard filtering capacitors of the Xbox aren't sufficient and can cause problems^[3][4][5].
