Currently Being Moderated2010. 11. 8 오전 11:15 (in response to SVegas08)I would start by trying new cables. VGA and Mini Display port adapter. Usually these can be the culprit. Also check the Hertz setting you have in the Display System Preferences against what the monitor manufacturer suggests this may be the cause of the lines and the color coming in and out as well.

Currently Being Moderated2011. 1. 30 오전 8:56 (in response to SVegas08)Hi,
I have a mid-2009 and later MBP. I am trying to use an external display - the Dell 2407WFP using a DVI cable and a MiniDisplay to DVI adapter, with it. The whole thing used to work perfectly well until a week or so ago. Here is what happens now:
1. Before I plug anything into the DVI cable coming of the Dell monitor, the Dell screen when switched on shows the DELL splash screen and then moves to showing the message, "No DVI-D cable". Dell documentation tells me is a self-test being performed by the monitor indicating that the monitor is working fine.
2. When I plug the Apple adapter (MiniDisplay to DVI) into the DVI cable coming out of the external display, the external display enters Power Save mode. Immediately, within half a second. Why is this happening?? This did not happen earlier. Please note that at this time the Apple adapter isn't even plugged into the MBP's MiniDisplay port.
3. As a result, when I do plug the whole thing into MBP's MiniDisplay port, the MBP screen flashes blue for a second (this used to happen earlier as well), but it returns to its regular screen and there is no activity on the Dell external display. No display is detected even after I've clicked Detect Display several times. The Dell external display appears to be in Power Save mode and is not waking up.
I have tried the PRAM and Display Preferences resets. Tried all combinations of switching both machines off, plugging in cables and switching them on. The basic thing I described in (2) above, i.e. the Dell monitor enters Power Save mode as soon as the DVI cable has the adapter plugged in, continues to happen every time.
Could this be the result of a faulty cable? Perhaps the white link - the MiniDisplay-to-DVI adapter? Should I take the Dell monitor along with the MBP to a store - even though the Dell documentation tells me that the monitor is giving me the sign that it is working fine.
Thanks a lot!!Macbook Pro 13", Mac OS X (10.6.3)
Currently Being Moderated2011. 3. 22 오후 3:17 (in response to visa-air)I have managed to fix the problem with different cables and converters as well. But the problem always returns. I also use Dell monitors (2408's mostly) but also the NEC ea231wmi. None of the dozens of suggested fixes ever work and then suddenly a few days later it will work again.MBP13mid2009, Mac OS X (10.6.7)

I think I have solved this issue, I do not think it has to do with the kind of display. See my post: https://discussions.apple.com/message/18028302#18028302
