1.This guide applies under the following conditions:
Windows 7 x86
Cat 10.6
HDMi output
DXVA mode
TMT3 using AVCHD RC1 HD test video
2. As you can see, 5670/5570, 4550 and 4670 behave differently, so you may obtain a different result. The goal is to make sense of the result so that corrective measures can be taken.
3. While the objective is to achieve consistent desktop and video playback level, there may be situations where it would make sense to sacrifice correct desktop level in exchange for better video playback quality like preserving BTB/WTW.
4. The file mode playback of both 4550 and 4670 are identical to the disc mode playback of 4550. 5670/5570 is different (see 9.). Madshi renderer was not tested.
5. Pixel Format YCbCr 4:4:4: and 4:2:2 give similar results.
6. Pixel Format RGB Full gives 0-255 desktop for 4550/4670, while the other three formats compress desktop level to 16-235. 5670/5570 only outputs compressed desktop level for all four PF.
7. 4550 is well behaved, with no difference in file and disc mode playback. Choose RGB Full/Dynamic Range Full for PC Monitor and one of the other three for TV accepting video level input. If BTB/WTW is preferred for TV, sacrifice correct desktop level and select RGB Full/ DR Limited.
8. 4670 disc mode playback behaves quite differently, either by design or otherwise. For PC monitor, select RGB Full/Dynamic Range Full. But best option for TV, it would appear, is YCbCr/Dynamic Range Full, giving consistent Desktop/Video level and preserving BTB/WTW, a combination not possible with the 4550 card.
9. 5670/5570 is like a 4670 without RGB Full. No longer possible to obtain full range 0-255 output for Desktop and File Mode playback. Not recommended for PC monitor.
