Impressed by the quality of the relation to the composite. The Wii U automatically detects a connection change to the ignition. This allows me to easily configure the display. Obligation to 720p / 1080i and the image is quite clean by cons I have a blurred image at 1080p, ultimately rather logical with my material.
If you connect to a PS3, consider disabling 1080p HDMI mode before connecting with this adapter, if like me, you have a screen or video projector with a low resolution. For the PS3, I have a multicolored horizontal band that appears below the image. It's a shame that night watching a movie, for example.
The sound works well out of the cable.
Regarding the case, it looks quite frail, I think we should connect the cables carefully.
Small update:
Unfortunately I have not managed to get a picture of the PS4 on my projector or on a PC screen FullHD (Samsung F2380) with this adapter.
I think I try all video modes, with HDCP on / off, nothing to do. This is unfortunate.
