This package contains profiles to use with older Apple Hardware as a solid starting point for the RetroTink 4K.
All included profiles are configured to use integer scaling by default. When setting these up, you will need to do the following:
- Run Auto-Phase and Auto-Gain for each mode.
- Check cropping and adjust if needed for each mode.
- Don't forget to save the profile changes afterwards.
By default, the CRT mask is disabled in these profiles. However it can be enabled in the RetroTink advanced settings. I haven't found great settings on higher resolution modes, but I do think the A Grill Dense masks are a good starting point to mimic Apple monitors.
When using one of the 60Hz display modes and a VRR compatible monitor, GenLock seems to work quite well.
When using integer scaling for the sharpest picture, some display modes will fill more of the screen than others. 4K displays seem to work best with 640x480, 832x624, 1280x1024 and 1920x1080. 1440p displays seem to work best with 640x480, 832x624 and 1600x1200.
Included in this package is a set of custom inputs modes to allow these profiles to include settings for many different display modes that are already tuned and ready to go. It also can help quickly create and dial in new profiles.
Apple Specific Modes:
- Macintosh 512x384
- Macintosh 832x624
- Macintosh 1152x860
Unusual Apple Timings over VGA:
- Macintosh 1600x1200 (UXGA)
- Macintosh 1920x1080
Aimed at early machines that include an Apple DB-15 video port and a VGA adapter. Should work with most 68K machines, and even early PowerPC machines. Has only been tested with System 7 and MacOS 8.1.
Tuned for 640x480 @ 67Hz, 832x624 @ 75Hz and 1024x768 @ 75Hz.
These are a collection of VGA profiles based on different video cards of the era. So far there are:
- ATI Rage 128 - VGA
- GeForce2 MX - VGA
These include an array of tuned display modes out of the box. To get the most out of these modes, it is stryongly recommended to use SwitchRes. The RetroTink cannot get optimized timings for different refresh rates at the same resolution/input mode, and MacOS doesn't know how to filter the list of supported modes to just the ones tuned in the profile. Using SwitchRes, you can easily limit the list of modes to the ones the profiles have been tuned for, and will work best with modern displays at 60Hz.
These profiles can also serve as a starting point for other VGA GPUs of the era if you want to experiment.
Tuned Display Modes:
- 512x384 @ 60Hz
- 640x480 @ 60Hz
- 800x600 @ 60Hz
- 832x624 @ 75Hz
- 1024x768 @ 60Hz
- 1152x870 @ 75Hz
- 1280x1024 @ 60Hz
- 1600x1200 @ 60Hz
- 1920x1080 @ 60Hz
DVI profiles are not included as they aren't needed to get optimized timings. Instead, we need to make sure the Mac is presenting the best signal to the RetroTink.
SwitchRes is strongly recommended when using a DVI GPU. Some cards like the Radeon 9000 Pro may only offer a handful of display modes as it detects the RetroTink as an HDMI device rather than DVI. In this example, the 9000 Pro only outputs 720p, and will upscale lower resolutions itself, which will look very fuzzy. With SwitchRes, you can enable the DVI display modes, and even enable 1080p output on cards like the 9000 Pro.
