I have configured my Minis in standard configurations. I recently conducted tests to determine performance. The tests were conducted using two outputs of a Mac Mini (one Mini DVI to DVI and one Mini Display port to Dual Link DVI). The tests were done with even layers on out 2 and odd layers on out 1.
The tests were all done with the following screen resolutions At both 60Hz and 75Hz:
- 2 x 800x600
- 2 x 1024x768
- 2 x 1280x720
- 2 x 1280x1024
- 2 x 1440x900
- 2 x 1920x1080
- 2 x 1920x1200
The results are as follows:
- 9 Layers 720x480@25
- 8 Layers 720x480@30
- 5 Layers 1024x768@25
- 4 Layers 1024x768@30
- 4 Layers 1280x720@25
- 4 Layers 1280x720@30
- 3 Layers 1280x1024@25
- 3 Layers 1280x1024@30
- 3 Layers 1440x1080@25
- 3 Layers 1440x1080@30
- 2 Layers 1920x1080@25
- 2 Layers 1920x1080@30
And special cases using a single Display port to Dual Link DVI with a TH2G in 2 or 3 output modes
- 3 Layers 2400x600@25
- 3 Layers 2400x600@30
- 2 Layers 3072x768@25
- 2 Layers 3072x768@30
- 2 Layers 3840x1080@25
- 2 Layers 3840x1080@30
Please note that in a long enough duration, even the best results showed occasional frame dropping when the tests were close to the threshold. Also note that all tests were done with 3 minute clips that did not contain in audio information. All testing was done using separate files on each layer in the case of multiple layer testing.
