I think you might be right. I may give it one more go and just call it. Even if it still is off I can't seem to make it any better than this.
There is some small amount of fringing on a "perfect" PCjr monitor (which I have). I still content that the thin font makes your problems worse, not better (the vertical lines don't always seem even in your shots).
For your EGA Wonder + 5151, run the latest CGA Compatibility Tester; I added a "monochrome CGA" luminance bars section that you can use to try to get all 16 shades distinct from each other.
Here are some examples of the 'normal' font provided by the mod. Notice how you can't even see the lines in the #, it's almost one giant blob.
How would you adjust the 'colors' on the 5151? I didn't think there was any sort of adjustment possible.
Maybe I'm just being too picky. I wish I had 'before' pictures to compare to. I guess y biggest gripe is the green/magenta fringing you can see on the text. Of course being an Apple II guy you'd think I'd be used to that.That's almost par for the course for a PCjr monitor. I'll set one up tonight and take a photo.
Brightness and contrast, to get them as linear/distinct as possible from one another.
If you were to ask me, that doesn't look exactly terrible for a peanut monitor. I have 1 in the garage, but don't think I have anything operational to drive it at the moment.
