So I discovered this nifty utility called Multi-Resolutions that allows you to force video cards to output video resolutions not natively supported by Mac OS 7. Via some ResEdit hacking, I was able to add 1680 x 1050 @ 60Hz to the list, which is the native resolution of my 22" LCD. Amazingly, this worked, and I now have System 7 running at this native resolution.

I tracked down the creator of this app, which is now almost 10 years old, and asked if he would be willing to release it for free, and possibly give me the source so that we can modify it to my liking. Within a day, he graciously sent me the code and told me to enjoy.

I'm not much of a programmer, and the source code is way more complex than I thought it would be, so I'm now seeking anyone on the forums who has experience with C and C++ on the classic Mac OS, that could possibly hep me design a better version of this program that does the following:

  • Changes the resolution during the extension/control panel load up, rather than after the desktop appears, so that icons and windows maintain their proper positions.
  • Add all the modern widescreen and full screen resolutions to the built-in list in various frequencies so that ResEdit hacking is no longer necessary.
  • Refine the look of the program.

Anyone who feels they'd like to take a whack at this respond to this thread, send me a PM, or send me an email and I'll share the source with you.

This would be a great benefit to not only System 7 users but all classic Mac users who want to run their modern displays at native resolutions.

For reference, this is a list of the resolutions I would like to see in the program (without the need for hacking as I had to do):

  • 640x480
  • 800 x 600
  • 832 x 624
  • 1024 x 768
  • 1152 x 768
  • 1280 x 720
  • 1280 x 768
  • 1280 x 854
  • 1280 x 960
  • 1280 x 1024
  • 1344 x 1008
  • 1400 x 1050
  • 1440 x 900
  • 1440 x 960
  • 1600 x 1024
  • 1600 x 1200
  • 1680 x 1050
  • 1920 x 1080
  • 1920 x 1200
  • 1792 x 1344
  • 1856 x 1392
  • 1920 x 1440
  • 2048 x 1536
  • 2560 x 1600
  • 2560 x 2048

I figure making all the resolutions available in 60hz, 75hz, and 80hz should pretty much cover all the displays anybody would want to force a resolution for. If there is any other resolution that I'm missing please let me know.

Also, might as well make all available refresh rates available to support as many monitors as possible...once you figure out how to implement one the rest should be a piece of cake so "why not?"...

(all in Hz)
56
60
65
70
72
73
75
76
85
90
96
100
120

Well, the way this program is right now, all the resolutions and refresh rates are listed in a single menu. Technically I don't think it should be too hard to just add all of them, but that might be a mind boggling list. Perhaps if we could instead figure out how to get separate resolution and frequency menus, that could solve that. But first we need to find somebody that can even do this...

A revamped application would be very nice. It might also be possible and perhaps a bit easier to create a wrapper using AppleScript to set specific resolutions.

I believe one of the short commings of this applications is that it does not detect limitations in the monitor, making it possible to select combinations of frequency and resolution that can be harmful and or destructive to the monitor.

Yes that was noted in the Read Me for the application that this could be a problem, although I believe most modern displays made in the past ten years will protect themselves from this (I know all mine do).
