The primary difference between QHD and 4K lies in pixel density, with 4K providing over 8 million pixels, allowing for unrivaled sharpness compared to QHD’s 3.6 million pixels. However, 4K requires more powerful hardware. Here are some other key differences between 4K and QHD:
- Resolution: QHD has a resolution of 2560 x 1440 pixels, while 4K has a resolution of 3840 x 2160 pixels, providing 77% greater pixel density than QHD. The added pixels of 4K offer improved clarity and allow you to sit closer to the screen without seeing pixelation, which is ideal for video editing. However, more robust hardware is required to power all those extra pixels.
- Pixel Density: Pixel density measures how compact or spread out pixels are across a display and is calculated by pixels per inch or PPI. On a 27-inch display, QHD has a PPI of ~109 and 4K has a PPI of ~163, allowing for crisper images, especially when viewed up close.
- Aspect Ratio: Both QHD and 4K typically employ a 16:9 aspect ratio, making them excellent for media consumption.
- Hardware Requirements: 4K demands processing and rendering over 8 million pixels per frame, which means a more powerful GPU is required, especially for video editing. QHD provides a significant visual boost over 1080p without the hardware requirements of 4K, making it a better choice for budget GPUs.
