UNSOLVED
DVI Connection Problem
I have a new Inspiron 530 and a new Viewsonic 2255wm. When I use VGA cable, everything works fine. However, when I use DVI cable, I have the following two problems:
1. The monitor does not turn on during the Windows Vista boot-up until Windows is fully loaded. The first thing I see is Windows Log-In screen - I don't get to see Dell's Logo and Windows loading.
2. The monitor does not wake up from power saving mode after computer wakes up from the Sleep Mode.
Please note that I don't have above issues when VGA cable is used. However, the image quality is much superior when DVI cable is used.
Please help. Thank you.

This sounds like a monitor problem since the video circuitry is working ( waking up ) when using the VGA Cable. Have you contacted Viewsonic?If you have another PC check the monitor reaction when it is connected to the other PC.pcgeek11690

I checked around some more on the Old Interweb and you are not the lone camper in the woods here is anothers anguish on this same problem on different hardware:" The Monitor (a "Dell 2407WFP-HC" LCD screen) gets no signal on boot-up until
Windows is loaded. Only then does it turn on. The screen is connected via DVI (looks noticeably better than VGA). MB is Asus A8N-SLI Deluxe, running latest Asus BIOS for this MB. Video card is Asus EN6600GT.
Troubleshooting : When I plug a second simultaneous monitor in the video card's VGA slot (a BenQ CRT), BOTH the CRT and the LCD display the full boot-up routine (DOS visuals). And of course, the Windows portion. Leave the VGA slot unplugged (with only theDVI plugged-in), and the whole DOS boot-up routine is bypassed by the monitor again. It gets no signal until Windows is loaded. What gives? Why can't the DVI slot emit anything until Windows is loaded, unless something is plugged into the VGA slot? I need to plug in a 2nd monitor each time I want to boot in Safe Mode, or else I can't see the menus. "and yet another poor soul:" Yesterday I received my Formac 20" display and it's gorgeous *but* it doesn't work with my 9000 Pro :(. I'm getting a signal from the DVI port because when I connect a CRT using the DVI to VGA connector the monitor works. All I get from Formac tech support is that the display must be set at 1600x1200, 60Hz. I've done that from the ATI control panel - still no go. Formac asked me to try a CRT monitor on the VGA port that will display 1600x1200 to wake the Formac up from a sleep mode (?) but my old CRT won't go that high. "The above posts are about a Dell LCD and a Formac LCD. Both exibit the same symptoms as you.

It makes me feel better that other people have similar problems. However, what's the solution? Have those people found solutions to their problems? Where can I find their threads? Thank you.690

Did anyone try a known good DVI single link cable? Make sure they are using the correct single link cable?690

There were no solutions in those threads and they were as upset as you.pcgeek11690

Mombodog:Here is my situation. Both monitors (Viewsonic and Samsung) came with DVI-D (single link) cables. Both monitors have DVI-D (dual link) jacks. My computer has DVI-I (dual link) jack. Should I be using a different DVI cable? If yes, which one?690

I am no expert on DVI, I just thought that might be an issue and worth a try.I do know dual link DVI is required for very large monitors, 30" and up using 2048 x 1536 and up resolution. This dual link started when Apple came out with their 30"Man I want one of these.All DVI female connectors look alike so you cannot tell what they are, only by the hardware specs for that device, it is the cable pinout that is represented in the diagram I posted.There are two kinds of single link cables. DVI-D digital only and DVI-I digital and analog, Like I said I am no expert, but I think you would want the DVI-I single link cable.I always rule out the simple things first. Could be a bad or wrong cable.I guess we both need to do some studyingI suggest looking at the tech specs for your graphics card also.Also check for any monitor settings buried in the control menu on the monitor itself.
