DisplayMate and HQV Tests

DisplayMate Tests

DisplayMate is a very thorough program designed to stress test TVs and monitors on various display capabilities as we ran it from our display testbed system and hooked up the Samsung B7000 LED TV via HDMI. All visual enhancements on the TV were disabled, with contrast levels, sharpness, and color temperatures fixed at 90%, 50% and "Standard" option respectively. We obtained varied results as we homed in on a handful of tougher tests and have jotted them here:-

Circular Geometry, Cross Hatch and Dot
Even linearity was observed on the crosshatch and circular geometrical shapes. Digital flat panels using digital inputs shouldn't have an issue with this test.

Screen Uniformity
The black background was consistent in most areas. However, brightness intensities towards the edge tend to change slightly when the viewing angle is varied.

Dark Gray Scale
This test is supposed to help you set the correct black levels, so we won't penalize any variations too much. However, there was a mismatch of tones between test block 16 and the one at the far right.

Color Scales
The blue band appeared slightly clumped at the brighter levels. Other than that, no major color tracking error was observed. Smooth gradients from zero to maximum brightness were achieved across the 25 steps.

256-Intensity Level Color Ramp
Uniform color gradations were observed across all four bands, with minor overlapping appearing towards the darker areas of the green and blue strips.

Silicon Optix HQV Tests

Silicon Optix HQV Tests come in very handy to assess image quality and handling of television displays, monitors and even the players through a variety of interlaced video signal processing tasks including decoding, de-interlacing, motion correction, noise reduction, film cadence detection, and detail enhancement. In our test assessment of the Samsung B7000 LED TV, we've programmed our Blu-ray set-top player as a 1080i source in order to stress the TV's video processor. This will force the processor to convert interlaced signals into progressive signals to accommodate the HDTV panel's native capability (or otherwise simply know as up-scaling). Here are the results we noted on two of the most crucial tests:-

Digital Noise Filtering
A sizable dose of noise was visible with when the TV's Digital Noise Reduction function was disabled. Once enabled, the TV's video processor managed to remove illegitimate noise by a good margin once we've set it to "High", and this was achieved without any visible loss in overall image detail. The B7000 also offers an "Auto" mode for automatic static noise removal, if any. The TV's temporal filtering looked good.

Video Reconstruction Tests
The Diagonal Filter test is used to determine the processor's ability in de-interlacing interlaced videos to progressive signals, especially where moving objects are concerned. The B7000 performed exceptionally well for this test, with hardly any feathering or 'jaggies' spotted on the rotating bar across all angles.
