Android TV-Out for presentation

I have do a study for how to connect android phone to projector / TV. HTC Desire HD and Samsung Nexus S (like most android phones) do not support TV-Out.

Until now, only Samsung Galaxy S has TV-Out function in Hong Kong. However, we cannot use Samsung Galaxy S as our development phone. Because we have used some Android 2.3 API for our Barcode Scanning customization and Samsung Galaxy S is used Android 2.2.

(p.s. HTC Desire HD is used Android 2.2 platform.)

An alternative solution - Android Screen Cast - it can mirror your app screen to your notebook and connect to a projector. The function is work, but the quality is not good (may be poor).

BTW, Samsung Galaxy Tab has TV-Out function and many of Android tablets have HDMI out. I am thinking that we can port our app to those devices for presentation only. But it may have extra effort for development.

(p.s. Samsung Galaxy Tab is also used Android 2.2 platform.)

All comments are welcome. Thanks!
