    DH67BL Video Priority Problem

    akc42

      I have a large 24in monitor connected to my HDMI output and a smaller 17in monitor with ONLY a VGA input connected to the DVI output via a DVI-A to VGA cable.

       

      In the BIOS I have set it to make the HDMI output the primary output and the DVI Analog to be the secondary output.  I have upgrade the BIOS to version 125 (ie the latest release)

       

      When I boot, the initial splash screen will always appear on the 17in monitor unless I unplug the DVI cable (just switching the monitor off doesn't help).

       

      What gives? Have I misunderstood the meaning of Video ports?

       

      (As an aside, I am running linux and although it appears to be in proper two monitor mode with the 17in monitor on the right of the main 24in monitor the 24in monitor is blank and only the 17 in monitor displays anything.  This is after boot.  Someway into the boot process, both monitors show the same screens until I log in, then it drops into the mode in the previous sentence)

          Can't help you with the Linux part but it sounds like you have the Primary Video Port set to Auto in the BIOS and/or the Secondary Video Port set to something other than "None".  Set the Primary to HDMI and set the Secondary to NONE. You'll probably also want to enable HDMI/Display Port Audio under On-board Devices > Audio.

            Nope

             

            The BIOS has been set to allow me to define the primary and secondary ports manually. And I have set the primary to HDMI and the secondary to DVI-Analog

             

            I just did a live chat with Intel tech support and the guy I was talking to it on it said that for the splash screen to come out on the DVI port regardless of the BIOS settings was correct behaviour.  Sounds more like a BIOS bug to me.  Basically there is ONLY an HDMI and a DVI port on the back of the board, so I have no way to drive a modern display which I want to be the primary and an old VGA only display as secondary.

              Okay, it's doing what you told it to do. If you want the primary and only boot output to be HDMI, the Secondary needs to be set to NONE.

                Keep in mind that the BIOS options are for boot only. If you want the boot to appear on the HDMI port, set the Primary Video Port to HDMI.  If you don't want the boot to also appear on another display set the Secondary to NONE. You're telling the BIOS you want dual boot displays if anything is defined in the Secondary. I can't make it any clearer than that. After booting, the OS will still use any display you have connected to the motherboard and you can define the VGA as an extended display (at least in Windows).

                  I understand what you are saying, but I don't think it is working in practice.

                   

                  Certainly even though I have set the secondary output to NONE, and the primary output to HDMI, the splash screen is appearing on the DVI-A monitor!

                   

                  Linux's Xorg Intel Driver seems to be using these values for something.  It appears to be reflecting these changes in the BIOS to how its is operating.

                   

                  I just managed to get a pretty well perfect setup for it, but I then tried rebooting and I have lost it all again.

                    Finally got it working - this splash screen is wrong, but that is a small price to pay.

                     

                    BIOS is set for primary HDMI secondary None - but still the splash screen comes up on the VGA port

                     

                    I set the Linux stuff up in /etc/X11/xorg.conf thus:

                     

                    Section "Device"
                        Identifier "H67 Integrated Graphics"
                        Driver "intel"
                        Option "Monitor-HDMI2" "Iiyama 24in"
                        Option "Monitor-VGA1" "Iiyama 17in"
                    EndSection

                     

                    Section "Monitor"
                        Identifier "Iiyama 24in"
                        Option "DPMS"
                        Option "Primary"
                        Option "PreferredMode" "1920x1080"
                        Option "Position" "0 0"
                    EndSection

                     

                    Section "Monitor"
                        Identifier "Iiyama 17in"
                        Option "DPMS"
                        Option "PreferredMode" "1024x768"
                        Option "Position" "1920 0"
                    EndSection

                     

                    Section "Screen"
                        Identifier "Default Screen"
                        Device "H67 Integrated Graphics"
                        Monitor "Iiyama 24in"
                        DefaultDepth 24
                        Subsection "Display"
                               Depth 24
                               Modes "1920x1080" "1024x768" "640x480"
                        EndSubSection          
                    EndSection

                     

                    And this gives me both screens visible! with the 17in monitor positioned to the right and with the top edges aligned.

                      I was just trying to duplicate the HDMI Primary and hung my system. (I have the same board.)  I know you have to boot after making the initial change but I happen to catch the system in a Defrag. Windows 7 didn't like that at all. I was stuck with NO display and trying to re-power. Ended up having to re-configure to get to the BIOS and set everything back and let Windows recover. So, I'm back and leaving everything as is. Anyway, glad you were able to get the displays working. I think you're right about a bug in the BIOS.
