    Using s-video on MII 12000

    While i am waiting for my new monitor, i thot i would install my system with my pioneer in dash screen. I had problems using the tv out, and by searching found that there was a problem which could be fixed using a resistor.

    I also read that you could use a svideo to rca adaptor, that this should work ok. I have tried this but still cant get the desktop to show on the pioneer screen. The only way i can get it to work is if i have a vga monitor connected at the same time. If i unplug the monitor the picture stays on the pioneer but when i reboot i am back to the same problem.

    I have tried changing bios settings but still cant get it to work. Am i right in thinking that by using a svid to rca adaptor i am not affected by the problem of insufficient resistance?

    Anyone offer any help??

    There is a workaround for this vga problem. It has something to do with bios wanting a vga screen plugged in during post. You can use a vga terminator (i think thats what its called.) It is basically a vga connector that puts a loop on some of the pins, fooling the computer into thinking there is a monitor connected. Have a search for the VGA loopback/terminator thingy

    Thanks for the suggestion, ill look into it.

    But i think the MII 12000 can display on svideo without a vga monitor present.

    In bios where you select display device, it has the option for tv only. This is the setting i have tried, with display type as svideo but i dont get any picture. If i select crt + tv then it works ok as long as the monitor is connected aswell.

    I have an EPIAm m9000 and I use the resistor trick to get the screen to work without a monitor. Go to radio shack and get an RCA y cable, buy some resistors (I don't know how many ohms, mine might be around a 100 but I don't exactly recall.) Put the resistor in one end of the y on the RCA cable, the other end goes to the computer like normal. The resistence should tell the screen to enable without a monitor attatched.

    You can also test and see if this is your problem by hooking up your computer to a TV and seeing if the video out automatically gets enabled. You might have to try a couple of TV's becuase not all TV's end up putting the resistence on the RCA cable to tell the motherboard it's there.

    Good luck.

    I tried the resistor on the rca cable and it almost works. I get the display from boot and can see bios setup screen and windows desktop aswell.

    But when i installed the vga drivers i only get the boot screen, not the desktop. The only way i get the desktop is if the monitor is connected aswell. In the display settings the tv option is greyed out so its still not detecting the screen.

    I tried it on another tv and it works fine. BTW i am using a 0.25W 68ohm resistor as this was the closest they had in stock. Could this be why its still not detecting it, but as i say it shows the boot screen.

    Maybe i will just uninstall the vga drivers, then it will work with resistor but without the monitor.

    Try a stronger resistor. I think mine is around a hundred ohms or something. The drivers in windows do have the enable vga output that shouldn't need a monitor attatched to for it to be enabled. It's a little wierd that you say it is greyed out but maybe VIA changed the drivers a little or something.
