Hi all,
I have a Macintosh PowerBook 3400, which has an actual VGA port on the back. I have tested this VGA port with a modern LCD monitor and can confirm that it works perfectly. However, I wanted to use it with a CRT monitor, which gives a more classic, nostalgic retro feel. I have two CRT monitors in my garage. I have tested them both with PCs and can confirm that they are both working. However, when I plug them into my PowerBook's VGA port and start up, it seems as if the PowerBook doesn't even recognize them. The screen does not come on, and there are no resolution options or anything for the monitors on the settings in Mac OS 7.6. The only noticeable physical difference between the VGA port on my LCD versus the built-in cord on my CRT monitors is that on my CRTs it looks like three pins are missing on the port, compared to the LCD in which the port contains all of the pins. I have looked into this on the Internet and have found that these pins typically aren't used in VGA, so it seems unlikely that this would be the problem, unless the PowerBook has some weird circuit that depends on these pins to detect a monitor present in the first place... Does anyone have a remote clue of what the problem is that I am experiencing and whether some adapter or something would solve the problem?
Thanks in advance.
