Video Playback Quality
The HQV benchmarks from Silicon Optix are one of the few available methods of evaluating the playback quality of Blu-ray, DVD and HD DVD movies. They have at least one objective drawback, however: perception subjectivism.
The three major developers of graphics solutions, ATI/AMD, Intel and Nvidia, are constantly optimizing video playback settings in their drivers, which improved the playback quality in general as well as HQV HD result in particular. Unfortunately, ATI and Nvidia do not take the HQV test seriously as not very high results indicate.
So, considering the subjective nature of this test, you should not view the HQV and HQV HD results as the ultimate truth.
Although DVD has become obsolete, ATI Radeon HD 4770 can’t boast high performance in it. The problem will most likely be resolved in the new drivers, and at this time we can only state that DVD playback is not among the strengths of the new graphics accelerator.
HD video playback quality on ATI Radeon HD 4770 is practically ideal: the chip shows the highest results in HQV HD test.
