I have a Mag 19inch LCD monitor and a Sapphire 3850 graphics card. When I boot up the display does not come on until Windows boots. I cannot access the bios of my motherboard. I tried a Samsung 22inch LCD monitor and I am then able to see the bios posting. I then switched graphics to a Sapphire X1950 Pro and switched monitors back to the Mag and I can see the bios posting again. The problem is the Mag monitor in combination with the 3850 graphics card that does not display the bios post. Any suggestions?
The BIOS is sending the display information to the monitor but, when you turn your PC on, the LCD will be sleeping and it will take 1~2 seconds to wake up when receiving the display signal. The monitor is working and even if the BIOS messages aren't displayed, you can still press the correct keystrokes to get to the SETUP screen or press PAUSE in the keyboard to see what's going on in the POST. If your LCD has a bicolor LED indicating the status (Standby/On) keep looking at it, when the LCD gets the video data, the LED turns instantly from amber to Green or blue even if the screen is still black. This way you can have an idea when the LCD gets the initial video signal and to press the keys accordingly. Your PC will also delay the video output from the secondary video card because it's detected after the onboard card.

It is not detected because the driver for that monitor is not installed for windows 7. Go to HP web site and get the driver for your monitor. Your graphic card will dictate the resolution for the monitor. The monitor will only tried to project the image within its capability.
the HDMI port is for connecting video and sound to a home theatre / surround sound system. I understand that this monitor only has a VGA connector.
The sapphire ati radeon 5570 graphics card has the following ports on the back to connect to a display: DVI (white), VGA (blue) and DisplayPort (the thin slot in the middle). You can use an ordinary VGA cable to connect the card to your monitor.
Unfortunately you cannot connect this card directly to your monitor using the DisplayPort.
It May just take the Motherboard a little while to recognize the graphics card. Try pressing Tab or F2 repeatedly when powering on and see if it goes into BIOS, there is probably a setting for the default video device there. which should be changed to the PCI graphics card.
you use a graphics card as your main output? and you have onboard graphics output too that you dont use? if so then you will have to plug your monitor lead into the onboard output socket to see bios. i think you need to go into bios and change which device starts from boot. it sounds like you have the onboard graphics as your boot device and windows using the graphics card.
I have no experience with the DVI links because such technology is still unavailable here in Argentina. We have DVI video cards but finding a suitable DVI monitor is another (long) story. I think that your card (that has 2 DVI ports) is initializing one port first (the primary one) and then, when windows starts, it initializes the other and outputs video from both ports. Try connecting the monitor in the other DVI port. If your card has a VGA output, the VGA gets initialized first.
