Tune Up Program:
- Geometry and Distortion
- Sharpness and Resolution
- Screen Pixel Resolution
- Color and Grayscale
Geometry and Distortion deals with aspect ratios, size and position. I could not find anything that needed adjusting.
Sharpness and Resolution speaks for itself. We all want a monitor that is going to transfer the sharpest and clearest picture possible. These tests ran the monitor through font tests, fine image details, single pixel details, horizontal and vertical intensity, bandwidth, moiré interference, and artifact from pixel densities.
Moiré was somewhat wavy in three colors, as were the other monitors tested: magenta, (the most flicker), green and blue. Although it wasn’t a constant, it was enough to make me notice, so I did some research. Moiré flicker or waves are common occurrences and happen in all LCD screens. What needs to be looked for is the amount; the BenQ FP241VW did have the least of the four, with the Acer having the most. The font tests were clear and crisp, with a readable 6.8 points and 9 pixels in 100% of the fonts I chose to test. The horizontal and vertical intensities were clear and crisp, all distinguishable, and my bandwidth was 255/255 at 100%. Single pixel and artifact screens: each pixel was bright and as I increased the amount of pixels, I was unable to make out distinct anomalies, a perfect match with the 22" BenQ monitor.
Screen Pixel Resolution was a rough one to test. It consisted of multiple variations of patterns and progressions of patterns, where I was looking for jaggedness, moiré patterns, inability to discriminate between closely shaped lines, and fusion of pixels, lines and objects.
There was no flicker with any changes, and transitions in images progressed without distortion. It was very hard to distinguish jaggedness in lines, but some were visible in the vertical, but none in horizontal. I could not see any fused lines, and patterns were very distinguishable.
Color and Grayscale is what I consider the fun section. Using the slider bars, different panels and overlays, you can compare color and contrast between different panels. Other tests included gamma factor, color tracking, saturation and multiple grayscale compression, and resolution patterns.
Colors were crisp and vibrant in all color tests. I did not notice the appearance of mis-colored pixels in the green and cyan, which did appear in font text screens of the other monitors tested. As per the Grayscale tests, no screen variations were visualized, but I did encounter some dips and bumps as with changing colors in these areas of testing. This can be due to hardware limitations and cable transference. Artifact was very minimal.
Also, unlike the other monitors, some added tests were Color Misregistration or Convergence Error test patterns. “Misregistration is similar to an out of focus image” What is expected is that you will see some thin color fringes around the edges of the image. All monitors will have some degree of Color Misregistration. At the time of testing, I did not have another monitor to compare to, but there did not seem to be a noticeable amount of misregistration.
