📐 Calculation Formulas

📐 Aspect Ratio

Aspect Ratio = Width : Height
Simplified = GCD(Width, Height)

The aspect ratio describes the proportional relationship between the width and height of a display.

🔢 Total Pixels

Total Pixels = Width × Height
Megapixels = Total Pixels ÷ 1,000,000

The total number of pixels determines the level of detail that can be displayed.

📱 PPI (Pixels Per Inch)

Diagonal Pixels = √(Width² + Height²)
PPI = Diagonal Pixels ÷ Screen Size (inches)

PPI measures the pixel density and determines the sharpness of the display.

📏 Pixel Pitch

Pixel Pitch = 25.4mm ÷ PPI
(25.4mm = 1 inch)

Pixel pitch is the distance between the centers of two adjacent pixels.

🔄 Scale Factor

Width Scale = Target Width ÷ Source Width
Height Scale = Target Height ÷ Source Height
Scale Factor = √(Width Scale × Height Scale)

Scale factor represents how much larger or smaller the target resolution is compared to the source.

🎯 Optimal Viewing Distance

Viewing Distance = Screen Size × 1.6
(For optimal comfort and detail perception)

The recommended distance to sit from a screen for comfortable viewing without eye strain.

📖 Resolution Guide

🎯 Choosing the Right Resolution

  • 1080p (Full HD): Standard for most applications, good balance of performance and quality
  • 1440p (2K): Great for gaming and professional work, sharper than 1080p
  • 2160p (4K): Best for content creation, high-end gaming, and large displays
  • 8K: Professional content creation, future-proofing

📱 Understanding PPI

  • Low PPI (72-96): Large screens, viewing from distance
  • Medium PPI (96-150): Desktop monitors, laptops
  • High PPI (150-300): Mobile devices, tablets
  • Very High PPI (300+): Premium smartphones, retina displays

🎮 Gaming Considerations

  • Competitive Gaming: 1080p for higher frame rates
  • Casual Gaming: 1440p for balanced performance and quality
  • Immersive Gaming: 4K for stunning visuals
  • Refresh Rate: Higher resolutions may limit refresh rates

💻 Professional Use Cases

  • Web Development: Test multiple resolutions
  • Graphic Design: High resolution for detail work
  • Video Editing: 4K+ for professional content
  • CAD/Engineering: High PPI for precision

📺 Display Technologies

  • LCD: Good for general use, affordable
  • OLED: Perfect blacks, vibrant colors
  • QLED: Bright, color-accurate displays
  • Mini-LED: Improved contrast and brightness

⚡ Performance Impact

  • Higher Resolution: Requires more GPU power
  • Frame Rate: Inversely related to resolution
  • VRAM Usage: Increases with resolution
  • Bandwidth: Higher resolution needs more data transfer
