HDR (High Dynamic Range) is a display technology that significantly improves picture quality by expanding the range between the brightest and darkest parts of an image while also providing a wider color spectrum. Unlike standard dynamic range (SDR), HDR can show details in both very bright areas (like sunlight reflecting off water) and dark shadows simultaneously, creating a more lifelike viewing experience. This technology requires both HDR-capable displays and HDR-formatted content to function.
HDR is a technology that expands the contrast and color range of content, allowing for:

Resolution vs. HDR: Understanding the Difference
Resolution refers to the number of pixels that make up a TV screen image. Common resolutions include:
Why People Get Confused
Resolution and HDR are different but it’s easy to get them confused because both features are marketed as picture quality improvements. Resolution (4K, 8K) refers to the number of pixels on your screen - think of it as the detail or sharpness of the image. HDR, on the other hand, determines how vibrant, bright, and contrasty those pixels can be - imagine the difference between a faded photograph and one with rich, vivid colors.
Real-World Example
Think of resolution like the number of crayons you have to draw with (more pixels = more crayons = more detail), while HDR is like the quality of those crayons (better HDR = richer, more vibrant colors and better contrast). You can have lots of basic crayons (high resolution with standard dynamic range) or fewer but higher-quality ones (lower resolution with HDR). The best experience comes from having both - lots of high-quality crayons (4K or 8K with HDR).
Why is HDR Important?
Watching HDR content on an HDR-capable TV allows you to see:
Should HDR Matter When Buying a TV?\
Yes, HDR capability should be a key consideration when purchasing a new TV, perhaps even more than resolution for many viewers. Here's why:
What to Look For When Shopping for an HDR TV
Remember: Not all HDR TVs are created equal. Some budget TVs may claim "HDR compatibility" but lack the brightness and color capabilities to show HDR content effectively. Reading professional reviews can help identify TVs that deliver genuine HDR performance.
What Content is Available in HDR?
Streaming Services
HDR content is most widely available through major streaming platforms:
However, it's important to note that even on these platforms, HDR content makes up only a portion of their libraries. Most older shows and movies remain in standard dynamic range (SDR).
Physical Media
4K Blu-ray discs often include HDR, particularly for:
Live TV and Broadcasting
HDR in live broadcasting remains limited:
Gaming
Modern gaming represents one of the biggest sources of HDR content:
