    Hi, I just purchased a new widescreen TFT 24" for my dell optiplex 755 PC. The display is from a graphic card I installed in the PC (Quadro 410) through a VGA cable. The previous display TFT was 20" and it had no problems at all.
    The issue it whenever I reboot my PC, it only displays the startup bios menu and the windows logo, then the monitor goes blank indicating that the cable is not connected. I then have to reconnect the VGA cable back to the 20", allow the machine to boot completely then change it back to the 24" and reset it to the recomendend display resolution (1920 x 1080). I reset it on both nVIDIA display resolution and windows display settings.
    If I reboot the machine after setting up, it boots perfectly, but after I try to reboot it when it has been off for while (more than an hour) I have to redo all that process again and its really bugging me.
    My cmos battery is working perfectly, I have even tried reinstalling the nVIDIA drivers and the VGA cable is also in good shape.
    Can anyone help, Please?

    Does your graphics card and monitor have other connectors like HDMI? Try using that kind of cable.
