Interlaced resolutions with GameEx and a Cab... possible?

[u-man]

As i try to Finish my Theme, I came into some trouble. I try to use a 768x576 interlaced Setting for the Resolution with a Common 15khz Arcade-Monitor. It Works so far, but in GameEx i have some garbaged thin Black Lines across the Screen. Now i Need to ask, if interlaced resolutions are possible in GameEx?

If someone with a Cab could check, if he has the Same Problem, i would be happy.

THx in advance u-man

I have run GameEx interlaced in the past with an ArcadeVGA but that was when it used to use DirectDraw. Theoretically it should be supported.

Thank you Tom for the information. How I can run GameEx in DirectDraw Mode? Is there an option to do this in the Setup-Wizard?

I always thought that I can only run MAME in the DirectDraw Mode. I am using a 7800GT -nvidia with Soft15khz and Windows XP SP3. If I use the 384x288 progressive Resolution, everything is fine and looks right. I just want to know, at what resolution I should keep my Theme and thought 768x576 interlaced is a bigger screen and can handle more "presenting stuff".

Error-Description: The black thin lines, dont cover a whole line, only a portion. So you have small, thin black lines over the whole screen, more like artifacts in line-form.

Can you take a photo of your screen (not capture an image as this will not show the line artifacts to which you are referring) and attach a copy here?
