When I installed mine, the picture was not clear in hdmi, regardless of the settings I tripotais. The solution is not simple but it exists: Press "source" to the connector (HDMI 1 for me) is highlighted and press "tools". Select "PC mode" and voila ...

In conclusion, this screen is an excellent PC monitor full hd, once the settings, but its ergonomics is very weak. Since it is mainly a small TV, everything must be done via the remote control, and we are left with 50 buttons instead of the 5 usually placed under the screens ...
