    Okay, so I know these probably get boring but I like to document the little things I do to maybe give others inspiration, ideas, or maybe a little bit of technical know how.


    Anyway onto the modding. Today I have decided to take the tools to my wall mount monitor, I am sure some of you have seen it already which was an old viewsonic flat panel I was given because the vga plug on it had been completely decimated. About 3 years ago I replaced the plug on the end by splicing in a new plug off an old monitor. The panel did not have a removable cord like modern panels do.

    The aim of this mod is to add such a jack on the back to allow me to connect any vga cord I have. The reason I even decided to do this was because the splice I had done years ago had started to fail with wavy lines and sometimes red or blue not displaying properly.

    I am sure some of you remember this little thing, If you dont its a great starting place for this mod

    As you can see the cord coming out of the back is the old vga cable

    There is the splice in the cable I did years ago, not my best work. But it seemed to work fine until now.

    This is the back of the panel exposed showing where the VGA cable mates with the controller board, which happens to be removable

    I dug this different VGA plug out of my spare parts drawer, it will be easier to fit in the confined space of the panel

    The connector and some wire cutt off of the original VGA cable, Liberated from the white housing it was in.

    This was an important step of the process. What I did was connect a wire to pin 1 of the vga plug on the end of my old cable, and used the circuit test or resistance test function of my voltmeter to see if it completed a circuit. I then wrote down which wire corresponded to that pin, and repeated for each pin on the cable. Since many manufacturers do not use standard colors it is important to know which wires do what.

    Another important step for me in soldering is to tin or pre-solder both the contacts on what your solding to, and the wires you are soldering. This makes it easy to just heat up the spot and the wire and you dont have to fiddle with adding more solder.

    And the obligatory shot of bit-tech.net on the monitor.


    One thing I have noticed is the picture is now much clearer, and there is no longer a problem of image ghosting or anything of the nature. On my next update i will be adding the new port to the back of the monitor.

    Thanks for taking a look
