[ConnectCore Wi-i.MX51] HDMI connector

i work on the development kit “ConnectCore Wi-i.MX51”, and i try to connect a HD display “DELL S2409W” with HDMI connector . to do this, i have set the resolution in UBOOT with this command :

setenv video displayfb:HDMI@1920x1080x16@60

and i rebooted the device. and now, the screen don’t display anything, i have a black screen.

Someone can help me?

Which EA kit are you using? The DEL one doesn’t currently support the HDMI interface (a new software release is coming soon that supports it).
