Switching monitor resolution in System 7.0.1

[VMSZealot]

I have a Quadra 650 running A/UX and hence System 7.0.1. Question is, how do I switch monitor resolutions - the monitors control panel doesn't show different resolutions, it just says Apple 21" Monitor (it isn't - it's a Samsung LCD). At the moment, I have to switch to MacOS 8.1, switch resolution and then reboot. Inconvenient to say the least!

i know this is an old topic, but have you figured it out? i have a Q700 and it's behaving exactly the same.. i even tried using the monitors control panel from system 7.5.5 but that didn't help at all, nor adding the 'quadra monitors extension' to my user's system folder.

Which monitor adapter are you using?

Are you also using A/UX?

i'm using this one with 10 switches:


my current settings are: 1-4-5-8 for "multiple scan 16" - the "multiple scan 21" one doesn't give me all the resolutions under 7.5.5

According to my notes at https://tinkerdifferent.com/threads/documentation-for-db15-to-vga-adapters.318/post-21290 , the MULITPLE-SCAN 16" and MULITPLE-SCAN 21" items are reversed. Which means MULITPLE-SCAN 16" is for 21" displays and therefore has more options.

aha, that actually explains a lot, thanks : ) it doesn't solve the <system 7.5.x and A/UX dynamic resolution switching thing though..

btw just some random info from here:

21" and 16" color monitors default to the “Page-White Gamma” profile which affects white balance. This can be changed in the Monitors control panel.

so that's why i'm seeing everything in yellow under A/UX by default even though i've changed it in the pre-boot system 7.0.1 and on 7.5.5 too.
