Indivision, LCD displays, and various resolutions
« on: November 09, 2009, 02:15:43 AM »
I just installed an indivision in my 1200.  It works great.  But I've noticed some unexpected (or maybe expected) behavior.  I set the workbench display to 640x400, which looks great.  But whenever I start a game or some other software that I think is using 320x200 or 400, the image gets narrower... like a lot narrower.  It's also distorted like the aspect ratio is wrong.  This is on a 4:3 lcd display.  Am I just seeing the amiga screen modes force-fitted into what the lcd display wants to display?  Or is something else going on?

If this is how it's going to be, I'll just switch to a CRT.  But it may be that what I need is a better LCD display that can make better adjustments for odd-ball resolutions.

Use this program, select PAL and NTSC low-res (game resolution) modes, and adjust your monitor's clock and phase settings for best picture. Clock can usually be fine-tuned to eliminate practically all vertical distortion (use one of the solid test colors like white), although the image likely won't fill the entire display area. Then play with the phase setting until you get the clearest picture with no wavy/horizontal lines running up the screen.

I would configure the Indivision for 50Hz PAL/NTSC modes if your LCD can display it, as it will provide much smoother scrolling.
