Title: Ajusting display area in Mac OS 9.2.2
Post by: SabithaSuki on February 10, 2022, 08:29:51 PM
So my Mac Mini G4 project I've been doing has a screen that is ever so slightly larger than the mounting bracket I am using (Its a macintosh classic curve smoother for LCD's), so my question is for Mac OS 9.2.2. and or 10.5.8, is there a way to adjust how much of the screen is filled / apply a crt style pincushion effect to shear the display image in a proper shape. I am aware of stuff like SwitchRes2 and SwitchResX, but that only handles the resolution side of things, not the actual image quality. The screen settings I have don't allow me to properly align the image without parts getting cut off by the bezel.

I don't want to have to resort right out the gate to invest in a new screen, so any help would be vital.

Hi SabithaSuki

Have you tried any of these?
Stepping Out II (https://macintoshgarden.org/apps/stepping-out-ii)
Big Screen (https://macintoshgarden.org/apps/big-screen)
On Mac OS 9, you may have to use PowerFPU (https://macintoshgarden.org/apps/powerfpu) for the above linked apps to work.

It would be cool, if you would attach a screenshot of you project and of the issue.

*Update: Just found something correlating to your issue. If the software doesn't work, (you still need a version for Mac OS X), you may need to make a hardware modification. Sense Line Selection and Horizontal Deflection Voltage are explained in this YouTube (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjF8pim8ff1AhXQlYsKHVcMBy4QqJcEKAJ6BAgHEBE&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dq_CB7gQTy38%26t%3D120&usg=AOvVaw0bi7mT9vnS-48Xh2I66tKu)
I'm guessing your issue looks like this? (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjGnceI-vf1AhVl-ioKHdVVB7kQqJcEKAd6BAgFEBs&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dq_CB7gQTy38%26t%3D1356&usg=AOvVaw326FBFeJhaUt90Z8zqSesl)

Ah no I'm using an LCD not a CRT. Here's what I have; a 9.7 inch LCD panel. I think I can run it in 1024 x 768 and just use Stepping out or Big Screen to force an 800 x 600 view mode in the visible space. Sorry I couldn't get a screenshot of the desktop, I hadn't gotten everything set up 100% yet.

Okay decided to just replace the monitor instead. Turns out most of the software works for ajusting UPPER resolution, not lower. Thanks for the advice that have been provided but things Aint sticking it seems.
