![]() Something should happen when pressing those buttons, even if just an error message of some kind. ![]() If the display is working at all - you should get a test image on the screen, maybe with a DELL logo, or just a small window telling you there is no video found.īe sure to try pressing each button along the right side, just to see if anything appears on the screen. Does the power light (usually in the lower right front corner) come on at all? Plug in the power cord - with NOTHING else connected to your display, just power. It might be best to unplug the power cord for a few seconds. ![]() You have tried a couple of different cables, so one way to test a possibly-failed display is to unplug ALL video cables. I missed that, even though that was exactly what you said. I did not notice that your display did not come on at all, and stays completely black. Thanks in advance because I have a little desperate situation here. So If someone have an idea I would really appreciate that. My Macbook pro knows that it has a the Dell connected and it's giving the 2560x1440 signal. If this doesn't work either, anyone has experience with (incredible expensive!!!) Mini Display Port to DVI Dual link adaptors? Because I have read the Apple One is not a reliable converter.Īnd, of course, I know that the issue comes from the Display port in Dell U2711. Someone told me that maybe is an issue with the pins of the cable, etc.and that with a Mini Display Port male - Display Port female and then connect the cable that Dell provides (DP - DP) things works better. I have an nvidia Geforce 9400M (latest drivers, etc.) working with Snow Leopard.I have the famous situation about "Entering in power safe mode", etc. I was reading some people said that this cable (Mini Display port male - Display Port Male) is going to work. I need to connect Dell U2711 to my mac book pro (with only a Mini Display Port), max.
