Getting a Micron Xceed Color 30 to recognize a Portrait Display as a portrait display?

[jckarter]

Hi everyone! I recently got my hands on a Micron Xceed Color 30 board. The manual mentioned that it supported the Portrait Display, so I thought I'd give it a shot, but it seems to be detecting the monitor as a regular 640x480 display and driving it with landscape timings, which gives some glitched output, with the left and right halves of the image swapped and overlapping each other as shown in this photo. I can find my way to the monitor control panel in System 7.5, but it doesn't appear to offer a way to change the resolution, only the color depth. My first thought was that the sense pins on the display connector might be dirty or damaged, but looking at the Xceed board's connector, sense pins 4 and 7 aren't even connected, while pin 10 buzzes out fine and looks properly pulled to ground as expected for a portrait display. I was wondering if you all knew, how does the Xceed board know to use portrait resolution? Is there a jumper or software switch somewhere I have to set, or should it be able to automatically detect the display?

The micron card does not autodetect anything, it is fully manual. You need monitors control panel from system 7.0 as the one from 7.5 does not work with MonitorXceed. If you have Color 30HR, use MonitorXceed 3.0/3.5, if you have 30, use 2.0.

With the Monitors from 7.0/7.1 and the appropriate MonitorXceed, you will be able to change resolutions.

Thanks! Using the MonitorXCEED plugin with the System 7.0 Monitors control panel did the trick.

Glad to hear it!

Incidentally, depending on the board reversion of your card, you may be able to pick up some additional resolutions with a new ROM. This would mainly be useful for something other than the portrait monitor, though.
