DELL U2311H HDMI>DVI

hi there!

i've just got the monitor for birthday. now i have 4 different HDMI to DVI cables here and no one works! the screen stays black.

for information i have an laptop running win7 prof. latest version. a geforce gt 540m (vers.267.21) and the sandybridge cpu (latest driver).

well now to the monitor. when i plug in the VGA cable he switched immediately to dell with the hdmi cables nothing, BUT he enters power save mode and when i remove the cable(hdmi) the status differs he tells me dvi cable not pluged in. so i think this is a reaction. then i downloaded the driver for this monitor which is called dell u2211h after unzipping. installing this driver worked manually with hardware manager (or how is it called in english versions? i have a german with geräte manager) then i choosed the u2211h digital not VGA or DP.

i think so far everything was correct. then suprisingly i was watching the reboot and the monitor waked up from power save maode and showed me the windows loading screen ( you know the one with the four flying flags or whatever). but then he switched to power safe mode again at the moment the welcome screen was loading windows desktop! so the cable is correct he shows windows loading screen , the monitor registered the plugged in cable, but where is the mistake or error?
