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. As I expected for an LCD display set at its native resolution, nothing needed adjusting. The display was showing the correct images, pixel for pixel.
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.
The Philips 200XW continued to impress me here and displayed a flawless image across the entire screen with no visual anomalies in the moiré tests. The font tests, like before, showed the reasonable lower limit to be 9 pixels and 6.8 points. Setting the fonts to 8 pixels resulted in a blocky font, only just legible, approaching the likeness of scribbly handwriting. This isn't a limitation of the screen, but of non-anti-aliased fonts in general. The bandwidth remained the best at 254/255 @ 100.4 percent.
The horizontal and vertical intensities were clear, although I began to notice a slightly odd characteristic of the display compared to my Mitsubishi CRT. With the LCD, the brightness intensity varies with viewing angle, whereas with the CRT, the brightness is consistent regardless of viewing angle. Now, this isn't really a problem as such, but there is a slight vertical gradient in brightness because of the effective change in the angle from the eye to the screen from top to bottom. Horizontally there was a negligible change, but vertically, this trait of the LCD display took a bit of getting used to. However, I was able to minimize the inconsistency by adjusting the up/down angle of the screen so that it was barely perceptible.
These tests appeared to be a collection of optical illusions, the type you would see in mathematical text books or posters adorning the walls of a student's dorm room.
All the tests showed razor-sharp lines; there was some jaggedness in the lines but, as with the font test earlier, this is just a limitation of using non-anti-aliased lines. You would see the same steps in the lines, and the same patterns in proximally close lines, on any display. The Philips LCD was proving that it could display razor-sharp pixels for anything I could throw at it.
Color and Grayscale is the last stage of the Tune Up Program. 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.
At this final stage of the test, it was very evident that the LCD colors, black levels, and white levels, had all been set to the absolute best settings possible. No matter what variables I changed, the images were absolutely flawless in every respect, with no artifacts or visual anomalies.
