If you are experiencing difficulty, first make sure that all cables are connected to their proper ports and are firmly connected and that you are getting power to the monitor, VGA adapter, speakers, and game console/PC.

NOTE: If you bought an X-Arcade Machine cabinet with an included PC, you wiill have a blank screen until the PC fully boots. This can take a few minutes, so please let it boot fully. MutliRes is already installed and configured.

X-Arcade Machine Cabinet:

  • Check that the VGA adapter is in the proper mode; Mode button in is for Console Mode (LED is lit), mode button out is for PC Mode (LED is off).
  • Console only - Make sure that the S-Video jack coming from the console is firmly connected between the console and the S-In jack on the VGA box.
  • PC only - Make sure the VGA cable is connected between the PC's VGA out and the VGA adapter's VGA In. Also make sure that the monitor is firmly connected to the Monitor jack on the VGA adapter.

Message on screen says "Disconnected":
This means that the monitor sees nothing connected to it at all. Check all of your connections.

There is no video displaying on the monitor or an "Over Specification"/"Out of Range"message:
The PC must be set to 800x600 or 640x480 (depending on monitor) at 60hz refresh rate. An arcade monitor does not report it's capabilities to Windows like a PC monitor, so you will need to manually do this. Here are 2 ways to accomplish this:

  1. Download MultiRes. Install it, and choose the option to have it start with Windows. Now go to Start>Programs>Startup folder and right-click on  the MultiRes icon, and change the Target to say: "C:\Program Files (x86)\MultiRes\MultiRes.exe" /800,600,32,60 , alternatively you can download our modified link (right-click and Save As) and put it in the Startup folder. For Windows 8 the startup file can be found at C:\Users\(User Name)\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\
  2. Boot the PC into VGA mode using one of the methods shown here.
  3. Log into the PC from another computer using Remote Desktop, Remote Assistance, or a program like TeamViewer or Your video card drivers may have advanced options to limit resolution/refresh, or you can try PowerStrip.
"Over Specification" when I start a MAME game:

You will need to open mame.ini file in the MAME directory and change like the following:

screen                    auto
aspect                    auto
resolution                800x600@60

  There is no sound:

  • Check that the speakers are turned on and at an appropriate volume level.
  • Check that the VGA adapter is in the proper mode; Mode button in is for Console Mode (LED is lit), mode button out is for PC Mode (LED is off).
  • Make sure that the speakers are connected to the SPK Out jack on the VGA box.
  • Console only - Make sure the red and white audio jacks coming from the console are firmly connected between the console and the red/white Audio In jacks on the VGA box.
  • PC only - Make sure the 1/8"-1/8" stereo audio cable is firmly connected between the PC's speaker out and the Line In on the VGA Box.

The video is discolored:
For a short time after connecting the power to the Machine, the picture may be temporarily distorted or discolored as it can be affected by the Earth’s magnetic field. By turning the Machine on for 10 or 15 seconds and then off for 20 or 30 minutes the automatic degaussing circuit applies a degaussing field around the edges of the monitor. You can alternatively degauss using the monitor's OSD menu, see the monitor's manual for more information.

The video is blurry:
Make sure you are sending the optimum resolution to the monitor, which is 800x600x60hz. If it is still blurry, you can try adjusting the focus as shown here.
