FullHDMI is an app created by orrebmas @ AndroidCentral which mirrors your HTC EVO 4G display onto an external display (HDTV for example) using the EVO HDMI port. Finally a good use for that HDMI port 
This application is currently in public beta but FullHDMI is stable enough if you feel adventurous.
FullHDMI has a few limitations which are the following:
- Sense: As of the latest release, FullHDMI only runs on Sense based ROMs. Plans to include AOSP are there but not until the core functionality reaches a mature enough state for Sense.
- Root: The latest release broke the app on non-rooted devices which was working in the alpha stages. So for now root is a requirement.
- Kernel: HDMI drivers had to be modified to enable hardware acceleration, and a special kernel is required as the drivers have to be compiled in. The kernel is needed for one of the two main modes of operation (see modes of operation below). It is necessary to run in hardware mode, but not needed for software mirroring.
This Kernel is totally stock HTC's 2.6.32 with the custom drivers added. It is not based off of netarchy's Kernel or any other. This may change in the future; the custom drivers are public.
