When Might An LCD Experience Distorted Geometry? 

Getting a monitor’s geometry to match up with the picture is an important aspect of its performance. For example, if an LCD display’s panel border is too thin or the white dot on the panel is too bright, it will not produce an accurate image. If the pixel response is too weak, the monitor’s internal details will appear distorted, making it hard to see the picture. Fortunately, this is a relatively common issue and should be easy to correct. Here are some methods of achieving this.

First, make sure the display is warm. It is not unusual for a monitor to take several refreshes to stabilize its light output. During this time, the screen may appear to be flickering, but this is not actually a problem. The flickering is caused by a faulty common electrode voltage. This can be easily corrected at the factory. Alternatively, it can be solved manually. However, the most accurate solution is to reset the monitor’s operating system and restart the computer. 

Secondly, use different tests to see whether the pixel response on the LCD is prone to shifts. In general, a monitor will exhibit more noticeable shifts when the screen is used for dark images. When the screen is used for lighter colours, the pixel responses will be a bit less strong. Using a test to check the overall pixel response of the display will give you a better idea of how well the pixel response will interact with the inversion pattern. 

Thirdly, check to see if the display can exhibit a pattern of interlaced lines. Depending on the inversion pattern, the lines can be interlaced vertically or horizontally. Interlace patterns are a visual artifact that can be seen on many high-refresh rate monitors. Generally, this appears as a faint horizontal or vertical band. 

Finally, be sure to check the colour gamut. Some LCDs can have colour depth problems that can cause shades to seem too similar. Fortunately, the Dell monitors’ colour gamut is quite generous and they were able to produce vivid shades. 

The Alienware XB323U GP showed a powdery trailing when displaying a dark background. Similarly, the Dell 24″ monitor produced a vibrant image. These monitors provide peak luminances of 232 – 265 cd/m2 under SDR. While the Alienware’s colour gamut is not as wide as other brands, the monitor is still capable of delivering excellent internal details. 

Although these monitors have a lot of advantages, the fact that they have limited luminance and motion-blur does not negate the need for careful testing and consideration. Moreover, OLED technology can be damaging to the panel, and the technology is often associated with potential image retention risks. Therefore, it is important to find out if the monitor is safe to use, especially if you are using it for reading and writing. 

Overall, the Alienware XB323U provides a great level of detail at a good price. There are a few issues, but they are minor and can easily be fixed at the factory.
