My DK3 looks great in my cab but there is a lot of extra space at the top and bottom of the screen. I tried adjusting the horizontal width coil and nothing happened. Here is a video of what I am talking about...



Is there something up with the width coil or is there supposed to be that extra space. It's not obvious when the bezel is on but I have a little voice in my say nagging me saying "The picture could be bigger you know..."

Any thoughts???

i pulled my dk3 book and the 5 pots on the monitor chassis that are located on the rear left side if your looking through the back. the pot on the far right is the vertical size is that not working.

All of the controls on a monitor chassis assume the horizontal position as a frame of reference. The Vertical Size Pot would be the Horizontal Width on a vertically oriented monitor. That is why you would have to adjust the Horizontal Width Coil in order to stretch the image vertically.
 
how much did you turn the width coil before giving up? lol. I have an EZ that's doing the same thing but I never tried adjusting it before.... I do however have a K7000 in my Street Fighter cab that the width was turned up too high, and me thinking that subtle changes to the coil would result in big changes was very very wrong. I thought the width coil or the C38 cap was bad on it when in reality, I had to turn the fuck out of the width coil before I got it to where I wanted.

otherwise, you're gonna have to do some headhunting in the circuit I guess... trace the width coil to another component that might be wonky. I'm no good at that, so don't ask me where to look lol
 
I think it's too wide and that the verical space is fine. The DK games don't take up the entire screen. There should be some space on the left and right, and even more on the top and bottom. When you stretch it out over the whole screen it messes up the proportions on the game. Check mame for a cross-reference on the proportions.

When you've got it set right and your monitor is right it would be very difficult for you to tell where your monitor stops and the monitor bezel begins. The image should "float" behind the tinted bezel.
