Title: help with VGA to Arcade Monitor cable
Post by: thetered on June 15, 2005, 05:49:34 pm

Ok, I've made one of these before using another Wells monitor and it matched up perfectly with the picture here, http://dragonsden.emuunlim.com/pinout.jpg Now I am doing it to a 19K 4901 and when I look it only has one connector and not two on the board, although the spot for the small one is there.  The schematic on the chasis shows it to be like the picture I posted.  But there is only the 6 pin connector with the RED, GREEN, BLUE, GROUND, POS V SYNC, POS H SYNC  and all 6 wires are present, do I just match the two POS SYNCs with the V SYNC and H SYNC respectively off the monitor cable?

ok match up your RGB and ground...thats done..

now you only have 2/wires left on your VGA Hack Cable.

This 2 wires just hook it to the proper H/sync or V/Sync.
First try the NEGATIVE sides and see what you get, if its not good, try the Postive side.

Now if you still don't get a nice picture, TWIST the 2/wires left from the VGA cable hack and connect this to the NEG/Vsync and see what you got.

For the WG4901 monitor that you got, it should have work when you connected the 2 wires to the NEG/VSync and NEG/HSync. Also it should have worked when you twisted the wires together and connected it to the Neg/VSync.
