MSUS Tech Tip - Emergency Screen Switch

If you connect your machine and boot up and see no image, but the LED light on the front displays "Macrosystem", you might just be in the wrong display mode. The correction to this is very simple. Let's say in this case you are connecting to a DVI monitor when the machine was already set in single analog mode (note: machines ship in analog mode first as a default and the machine does not auto detect your monitor connection). The screen on the DVI monitor would appear black. There is a trick to use your trackball's right click buttons to switch screen modes without seeing the display. When the machine is powered up (theoretically it's on the main Bogart menu, you just can't see it right now) hold the right trackball button down for 6-7 seconds. The front LED should suddenly change to say "Display". It would be followed by the current display mode it is in. If the system was in single analog mode, it might say "Display: Scart". Pause, then you can press the large left trackball button to toggle to the next display mode (or the number keys off of the keyboard can be used too as mentioned in the next paragraph). As the system was set to single analog, the next mode would be DVI. Just wait about 15 seconds between screen switches. This should now switch the system to single DVI output and you will see the menus on the DVI monitor. This method is simply an emergency back door trick to switch monitor modes.

Using Bogart 2.4c or Bogart 3.2c, the emergency screen switch function can also be used on the Media Manager portion of the system. This would be useful in cases where you switch from Bogart to Media Manager and your screen display suddenly goes black. In most cases this means the Media Manager is resting on the main menu and has been set to a different monitor mode than you are using on Bogart. If this happens, same thing as before. Switch over to the Media Manager like usual to see the black screen. Then hold down the right trackball button for about 6-7 seconds. You will see a message on the front of your LED screen on the machine to indicate it's now in the "Display" mode. Using your keyboard, use the number keys to switch the appropriate type of screen display. 1 = Scart or the analog output. 2= DVI output. And with Bogart 3, the 3= HDMI output using the HDMI port on the back of S2000 or S4100 models.
