If I change my laptop to 640x480 resolution and connect it to the monitor via VGA, should it display without needing any other adjustments?
I've tried this and I get a message indicating, "Out of Range".
I've never seen this monitor work before (it came in a broken cab I bought) but it does power on and the message changes from "No Signal" to "Out of Range" whenever I plug my PC into the VGA, so I'm hoping there's just something else I don't know about that needs to be addressed in order for the picture to display.

first thing to check is that the vga interface board has the connectors in the correct place,there is a cable that goes to the neck card and it should be plugged into the vga header
out of range is normally a resolution that is not recognised by the monitor,640 x 480 should be fine though
if you enter bios will it display anything?
-
I don't know much about arcade monitors or CRTs in general, but I can take a look where the VGA plugs in to make sure everything looks connected. Forgive me for my ignorance, but when you say bios, do you mean for the laptop or is there a bios for the monitor I should be able to access somehow?

laptop bios,every single vga capable chassis i have ever seen will handlw cmos resolution
this is the chassis connection diagram,you will see the vga interface pcb in top left

Ok, so I checked and everything seems to be connected. I pulled up bios and it still said Out of Range. I switched my laptop to 640x480 and 60 hertz and the screen just went black with no message displaying. When I switched back to my regular resolution it said Out of Range again. Any idea what that might mean?
-
out of range is a frequency that the chassis does not recognise,i would suggest you try a different video source on the chassis before looking at chassis faults
does your laptop actually recognise a secondary monitor attached in diplays settings?
-
Yeah, my laptop did recognize there was another monitor and gave me options to extend/duplicate display. I can definitely try another method. I've got a PC coming soon that will have a Radeon HD 8350 Graphics Card to run GroovyMAME. I'm told I'll need to get a DVI to VGA adaptor. Could you help me understand what I'll need to do to connect the PC if I'm not using the VGA port on the monitor? Thanks in advance. This is the first time I've ever messed with a CRT and it's my first build, so I'm just trying to learn as I go.

Drive-by question: Your desktop background isn't black is it? An extended desktop that has nothing on it would only show the background color or picture. It would be easy to think it wasn't working. (It's been done before)

That's an excellent point, but no it's just the default blue Windows 7 background.

There are several things that can go wrong at the same time when trying to connect an arcade monitor to a modern card. Even if the card detects the monitor it might refuse to output video if no edid is found. You're in the right path by extending the desktop to the secondary output using a supported resolution. What I'd do is to use an external PC monitor to enable the output, instead of the arcade monitor. Then make sure the signal is 31 kHz (assuming your arcade monitor is the D9200), you do this by entering the PC monitor's on screen display (osd) and it will prompt the actual frequencies somewhere. *Then*, without turning your computer off, unplug the vga cable and hot-plug it in the arcade monitor. This way you make sure a proper signal is enabled. Keep in mind that laptops usually have vendor crap installed to detect hot monitor switching, so the powerpointist crowd can handle projectors. This may also interfere with this method. In short, a laptop adds more variables to the list of things that can fail as compared to a desktop pc.

Not trying to hijack this post but I just got a D9202 and Im running GroovyMAME, I saw the Bios screen come up but nothing else . I am using a standard Intel graphics card. I'm not sure what to do next.

double check you are running at 60hz refresh rate, sometimes windows likes to default to 75hz which these monitors don't like.
