Xbox:HDMI Output
Modern TV's may not have component/composite inputs 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 very useful on a 1.6 Xbox and arguably gives the cleanest picture of any solution on any version of the original Xbox. However, this solution will also require the most soldering and is the of the most expensive solutions.
Xbox:OpenXHD a community driven, open source project is in development based on the work of Ryzee119 for an all digital HDMI solution.
The only currently available retail project, is not listed here due to legal threats from the manufacturer.
Plug in & play converters
Another option to use HDMI is to use a 'plug in & 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.
This solution requires no soldering and has a broad range of quality and price.

Other options include "Kaico adapter", "Pound", "Hyperkin", "Portta" or modding a "Wii2HDMI", however these are more for convenience as for signal quality and will be beaten by a decent component cable.[2]
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 on board filtering capacitors of the Xbox aren't sufficient and can cause problems[2][3][4].
