Works, but not at 1440x900 screens

The adapter makes a good visual and stable impression. I use it with a Asus Transformer Pad TF300T.
Unfortunately, it is in Android 4.2.1 is no longer possible to set whether you want to transfer the full 1280x800 (with the bottom toolbar) or 16: 9 - 1280x720 screen (without the toolbar). This has with Android 4.1 is still working, but because the adapter can not do anything for.

The adapter itself is doing almost everything he should. An image with the resolution 1280x800 transferred to full HD devices (monitors and projectors) is no problem, but it does not work, transfer the image to a monitor with resolution of 1440x900, the monitor remains easy black. Very sad when you consider that both 1440x900 and 1280x800 correspond to the 16:10 format and would therefore actually fit perfectly. But for presentations or videos on said devices, the adapter is good and recommendable. With exotic screen sizes and resolutions, however, one should not burden him.
