Full HD vs. QHD
What's the Difference?
Full HD, also known as 1080p, offers a resolution of 1920x1080 pixels, providing a clear and crisp image quality. On the other hand, QHD, or Quad HD, has a resolution of 2560x1440 pixels, offering a higher level of detail and sharpness. QHD displays are ideal for those who require more screen real estate for multitasking or for viewing high-resolution content such as videos and images. While Full HD is sufficient for most everyday tasks, QHD provides a more immersive and visually stunning viewing experience.

Further Detail
Resolution
Full HD, also known as 1080p, has a resolution of 1920 x 1080 pixels. This resolution is commonly found in TVs, monitors, and smartphones. On the other hand, QHD, or Quad HD, has a resolution of 2560 x 1440 pixels. This higher resolution results in sharper images and text compared to Full HD.
Pixel Density
Pixel density refers to the number of pixels per inch on a display. Full HD displays typically have a pixel density of around 400 pixels per inch. QHD displays, on the other hand, have a higher pixel density of around 500 pixels per inch. This means that QHD displays can show more detail and appear sharper than Full HD displays.
Color Accuracy
When it comes to color accuracy, QHD displays have the edge over Full HD displays. QHD displays are capable of displaying a wider range of colors and have better color accuracy compared to Full HD displays. This makes QHD displays ideal for tasks that require accurate color representation, such as photo and video editing.
Power Consumption
One of the drawbacks of QHD displays is that they consume more power compared to Full HD displays. The higher resolution and pixel density of QHD displays require more processing power and backlighting, which results in increased power consumption. Full HD displays, on the other hand, are more energy-efficient and consume less power.
Price
Another factor to consider when choosing between Full HD and QHD displays is the price. QHD displays are typically more expensive than Full HD displays due to their higher resolution and advanced technology. If budget is a concern, opting for a Full HD display may be a more cost-effective choice.
Usage
Full HD displays are suitable for everyday tasks such as web browsing, watching videos, and gaming. They offer a good balance between image quality and performance. QHD displays, on the other hand, are ideal for professionals who require high-resolution displays for tasks such as graphic design, video editing, and CAD work.
Conclusion
In conclusion, both Full HD and QHD displays have their own set of advantages and disadvantages. Full HD displays are more affordable and energy-efficient, making them a good choice for everyday use. On the other hand, QHD displays offer higher resolution, better color accuracy, and sharper images, making them ideal for professionals who require top-notch display quality. Ultimately, the choice between Full HD and QHD displays will depend on your budget and usage requirements.
