Congrats, you are doing well... told you it was a PITA, configuring the monitor is definitely tedious but you will be able to do it if you follow my guidelines EXACTLY.
Here is the exact sequence you have to do, do it and you should be fine:
First thing you are going to do is to change the language, then the resolution (change it to the 3rd option works best (1024 x 768). Then adjust the trim pots at the vga card. The 3 trim pots are for your colors. Usually these cards ship with these trim pots adjusted to full output making your colors very washed out (mines were already adjusted to half but yours might be different, it definitely looks better at half (i tried other settings)).. Turn them to half, all of them the same the best you can. This will give you very good contrast and brightness.
Then play with the following settings,
Clamp ST and Clamp SP, this will prevent your screen from turning pink or purple (mine went all purple before i did that, never again once i adjusted that option). Under geometry I believe. Also these controls the horizontal scan of the picture.
This is how you set it the best, IMO.
Start with the clamp that by default starts at 90. Start going down in numbers(89,88,87,…)not up in numbers (very important step). At some point the screen will go black. When it goes black, go one more number down(at 62 it turned black, set it to 61. Just an example, ok. Your number might be different)
Now start adjusting the other clamp that by default it starts at 95. At 62 (remember, its just an example) your screen should come back full screen with really good colors and it should not turn pink on you anymore. Leave it at this setting.
Go into the game monitor test and set it to convergence (or cross bar check). All you need is an image that shows a full screen with vertical and horizontal lines. After this hit auto adjust at the monitor itself. The monitor should adjust the screen to full filling the image all the way to the edges.
If needed, then go back to the vga card and stretch the image horizontally and vertically.
