HQV Benchmark 2.0 Analysis – ATi, nVidia and Intel

Overview:
This third chapter focuses on Full HD resolution test patterns to test the scaling and filtering ability of the video processor.

Notes:
It is important when doing these tests to ensure that scaling is disabled both on any panels and in the driver software. Luminance Frequency Bands appear as alternating black and white stripes. The higher the frequency the thinner the stripes will be.

For this test the top half of the screen displays a set of eight boxes of vertical luminance bands and the frequency of the bands increases from the lowest frequency box in the top left of the screen to the highest frequency box in the second row on the right side. The bottom half of the screen displays the set of complimentary horizontal luminance bands.

Scoring:
Ideally, both sets of frequency bands should appear as a series of increasingly thinner lines. The lines in each frequency box should form a uniform pattern, evenly spaced with no artifacts or distoration.

Luminance Frequency Bands (Score either 5, 2 or 0)
Uniform and full amplitude on all bands and without ringing or ghosting of the lines outside the pattern. – Scores 5
Some non-uniform or attenuation only on the highest band or mild faint ringing or ghosting. – Scores 2
Some non-uniformity or attenuation on any bands or heavy ringing or ghosting. – Scores 0

The majority of graphics processors score 5 in this test however we noticed some mild ghosting with the X4500 solution and ghosting with the nVidia G210 and G220.
