So i just got the Dell U2412M and additional Displayport to Displayport cables. Happy as a lark, i set everything up with the Displayport cables, powered on my PC and what do you know, just a tiny window which says no connection detected and going into power-saving mode in 5mins. So, i switched to DVI and voila, everything works like a charm! So thinking it might have needed DVI as an initial connection, i plugged in the Displayport cable again and this time via control panel by the side of the monitor i changed inputs. It detected the connection but displayed only the default Windows 7 wallpaper. Tried pressing random keys on keyboard and mouse but to no effect. Switched back to DVI and its back to normal again.

Question: Anyone experiencing this issue? Is the monitor's Displayport connection faulty or the cable? On a side note, if the monitor's port is faulty, i was thinking that i could just live with it and save the hassle of exchanging it for another set since DVI is working. Is Displayport a better connection than DVI? I'm running 3 of those exact screens, two using displayport and I've never had any issues.
When you added the Displayport connection, was the DVI still plugged in? Just displaying the desktop sounds to me like it was treating your monitor as a second, extended display. Possibly it thought the DVI connection was a different monitor. The only thing I'd try would be to boot to windows, log in, disconnect your DVI cable and then try the displayport (explicitly selecting the displayport input on your monitor too). If that doesn't work, I don't have other suggestions. Maybe others will? Still: Displayport over DVI gives you: - the ability to pass audio (but no speakers on those screens, so irrelevant to you) - support for daisy chained displays (not supported on the U2412Ms - or really any screens at the moment!) - support for 4K displays (but yours are 1200p - so irrelevant to you) - 3+ monitor support on AMD graphics cards.

Otherwise, DVI or displayport doesn't matter. If you don't care about any of those things, there's no reason to go with displayport over DVI.
Still, it's frustrating when something should be working and isn't! Hi Rhysiam, thanks for taking the time to reply. Yes, my DVI connection was plugged in when i connected the DP cable to both my PC and monitor and when i changed the input settings via control panel to DP, the screen refreshed to being all black and then the default WIN7 desktop came on but without icons or taskbar. I only did the above only because when i was hooked the monitor up to my PC, i did via Displayport and it did not register the connection. Also i totally agree thats its frustrating when you know something should be working and it isnt. BTW, im running a single monitor setup with an Nvidia gtx 680 with the latest gpu drivers. Anyhow, thanks again for replying.
Will keep you updated. What you describe is usually what you see on a secondary monitor.

That's why I suspect having both the DVI & Displayport connected at the same time, Windows decided there were two monitors and configured displayport output as a 'second' display with an extended desktop. OP - there's a pretty good chance that if you copy what you did above, but remove the DVI cable from the computer before attaching the displayport, you'll get the outcome you want.
The fact that it comes up at all means that your GPU, cable and monitor are all working. That's a software/config issue. Another Option: Even do what you did above with the Displayport as a second display.

Check it's working. Go back to DVI on your monitor (which windows thinks is your 'main display'), go into your 'Screen Resolution' Settings (right click on the desktop), there you can change your main display to the second (displayport) display and tell windows to disconnect the DVI display (under the multiple monitors drop down). Go back to displayport on your monitor (or just set it back to auto) and all should be good. It should, however, come up at boot though when it's the only output connected. I still have no explanation for that not working. Ok guys, you are gonna cuss me but the problem was that i did not plug the Displayport cable fully into my GPU.
Yes, i thought the initial threshold was adequate and being OCD. I did not want to put any more pressure as this is my very first PC build with no prior experience whatsoever. Hence thats the monitor did not detect the DP cable on my very first startup. When i switched to DVI and plugged in DP the second time round with it, the windows desktop came on.(guessed i plugged it in fully this time round) without taskbars and what you said made me realise that indeed Windows might have just recognised the DP connection was a secondary monitor. Hence, i went and unplug everything and plugged in Displayport only and voila, it worked! Thanks for suggesting that Windows 'thought' that DVI was my main display and not Displayport when i had both connected. That really made sense to me and got me to redo everything again.
And i will be abolutely sure to be plugging my peripherals and hardware fully in future! Merci Beaucoup!!
That 'Apple Mac OS' is listed as a possible pop-up selection when attempting to download the latest drivers for your Dell computer. Discrepancy, of course, has sparked a lot of speculation about a Mac OS X/Dell pairing. The additional website pick-list option, however, may have simply found its way onto Dell's support site for existing which Dell does produce Mac drivers for. However do appear under 'Mac OS', but all appear to be Windows executables with the exception of the. Dell's CEO has publicly that they would be 'happy to offer' Mac OS X for PCs if Apple were to allow it.
