Widescreen modes in OS 7.5 on 6100?
Posted by: somedude on 2016-06-17 16:49:27
Does the OS allow custom modes?

I am tempted to say that I will never be able to get something like 16:10 so that it would look right on an LCD.

Since the video is technically capable of 1024x768, would it be possible to do say 1024x640?

Not really, not on its own.  It usually gets monitor information from the video driver.

However, there're a handful of apps that let you create custom resolutions and force the video to use it.  It's potentially damaging when dealing with CRTs, but perfectly safe if you wanna get it to work with an oddball LCD.

If you can find an older version of SwitchRes that'll run on System 7.5, I think that might do it for you.

If you ever succeed at this, do let us know.

Most modern monitors that I've seen won't display resolutions they don't understand, so a custom resolution probally won't work. The video card may not have enough memory for such a thing. But hey I could be wrong please let us know if you ever get it working.

Interesting notion, definitely keep us posted.

Bottleneck in hardware would be the capabilities of the RAMDAC. The only truly flexible video resolution setup of which I am aware would be the SuperMac Spectrum/24 which pre-dates video resolutions for the Mac being set in stone. It would be capable of doing what you've described, but later versions of the card had only the standardized fixed resolutions available.
