DVI and HDMI are the exact same signal, except that DVI doesn't include the provision for audio. Essentially the problem you're having is that you have the monitor set to auto input rather than HDMI input or DVI input. Setting the monitor to not look for any input you plug in and defining the input should cause the hunting wait to be eliminated.
Any contemporary monitor is able to switch analog/digital mode automatically if connection from signal source to monitor is set up properly.
Connect digital output from your graphic card to DVI input of the monitor. Disconnect any other signal cables from monitor and switch on both devices (PC & monitor). Wait a while. Monitor checks its inputs and a activates digital DVI, because it is only one active input on it.
If none picture excluding error message of monitor is displayed, go through these steps: 1) Check whether your monitor is set for automatic input selection. If monitor buttons have no response try to use analog input to activate screen (any picture, desktop background...) and then get monitor menu access by pressing menu button.
2) Find out what connector type has your graphics card in PC. Possibilities are: DVI, HDMI, DisplayPort and some their options. See Wikipedia for connector look if you are not sure. Remember that blue D-SUB (VGA) connectors are analogue and you cannot activate digital mode through analog VGA cable.
3) Use appropriate cable to connect monitor to PC. Example: Your PC has HDMI output. Use HDMi-to-DVI cable. Your monitor input is DVI and common DVI-DVI cable is not suitable in case you have PC with the HDMI. Note that DVI-to-DVI, DisplayPort-to-DVI etc. cables are available. You must buy right one.
Be aware that "Auto" button is inactive in digital mode of monitor.
Since you pushed the Auto button it is possible that the monitor has changed the input type to a type other than that you are currently using.
For instance it may have chosen to accept VGA input however you have the DVI or HDMI connected.
To fix this you will have to push the auto button again, and possibly again to get it to find your current input channel.
You may need to turn your computer off and then back on again.
You may need to connect your monitor using a different connector, example via VGA, DVI or HDMI. It all depends on the connection you have at present.
Blue Connector is VGA.
White connector is DVI. HDMI is very narrow conector usually black.

DVI ==> Digital Video Input
If your monitor has both DVI and VGA inputs, and your PC's video-card has both DVI and VGA outputs, then buy a DVI-to-DVI cable, and use it, for a better picture.
If your monitor has both DVI and VGA inputs, and your PC's video-card only has VGA output, then use a VGA-to-VGA cable. Or, purchase a video-card with DVI output, to replace the video-card with VGA output, and then use a DVI-to-DVI cable.
you can use on all vga cards(you dont need any special controler), this monitor has a USB hub and its is detected normaly on winxp or above, and the vga cards detect the monitor auto. i give you the monitor specs, take form website

Can't say I really "fixed" the problem. I tried other monitors, DVI cord and took the laptop to a repair shop. Nothing worked. And then....boom.....it worked! No one knows why or how. No one did anything to the computer or monitor. It just works. Who knows how long it will work, but it works today.
You will not benefit from the DVI input unless you have DVI output on your computer. The great advantage of DVI is that the picture is transferred in digital form all the way from your computer to the individual pixels on the monitor. If you only have VGA output on your computer then you will never get a better picture than by using a good quality VGA cable to link that to the VGA input on your monitor.
The DVI plug is designed to carry both digital and analogue (VGA) signals on the various pins, so "adaptors" exist to allow a VGA monitor to attach to a DVI output on a computer. Monitors may also support VGA input from their corresponding DVI input sockets, but the picture quality will never be better than by using a good VGA cable because it is still not using the digital capability of the DVI interface. What's more, because you may need more adaptors and thinner conductors in the cable, you will probably achieve a marginally poorer picture than with VGA to VGA.
When you next buy a PC or a new video card, get one with DVI to take advantage of your new monitor. In the meantime, your best bet is a quality VGA to VGA link.
Sorry that's not what you were wanting to hear, but I hope it will help you avoid further frustration.
