The reason why Dell uses WVA screens is that they offer a wider viewing angle and more vivid color reproduction capabilities.
The advantages of WVA LCD screens are that the displays with WVA panels have a wide viewing angle, purer black display, high contrast ratio, and accurate color reproduction. The disadvantages of WVA panels are that they have relatively high power consumption, slow response time, average panel uniformity, and slightly poorer viewing angle compared to IPS.
At present, there are quite a number of monitors using WVA panels in the market, and the corresponding prices are also relatively high. The mainboards are still targeted at mid-to-high-end users. It is believed that in the future, with the improvement of technology, WVA panels will also become the mainstream in the current market.
The main feature of the WVA panel is that it has higher brightness and contrast. It can achieve a high contrast ratio of 3000:1. The black and white tones in the picture are purer, and there are no issues such as light leakage.
Dell Laptop Purchase Tips
If you don't use your computer for a long time, you can temporarily turn off the power of the LCD screen by using the function keys on the keyboard. This not only saves electricity but also extends the lifespan of the screen. Do not forcefully close the cover of the LCD screen, and do not place any foreign objects between the keyboard and the display to avoid damaging the internal components due to excessive weight of the cover glass.
Do not touch the screen with your fingers or sharp objects (hard items) to avoid scratching it. The surface of the LCD display screen may attract dust due to static electricity. It is recommended to purchase a dedicated cleaning cloth for LCD screens to clean your screen. Do not pat it with your fingers to prevent leaving fingerprints, and please wipe gently.
When there is no external power supply available, if the card in the PCMCIA slot cannot be used at the current working state, it is recommended to remove the card first to extend the battery's usage time.
