Unraveling the Mystery of TV Measurement: What You Need to Know
The TV measurement process involves a series of tests and metrics that assess a display's picture quality, brightness, color accuracy, motion blur, and range of contrast. While different manufacturers use their own proprietary methods, several industry-standard tests provide a benchmark for revealing a television's capabilities. These tests measure various aspects, including color gamut, color volume, motion, and audio performance.
At the core of TV measurement is the Adaptive Sync, a technology developed by VESA (Video Electronics Standards Association) aimed at enhancing TV user experience. To quantify a TV's motion, brightness, and contrast, TV manufacturers use two types of syncs: 120Hz and 120Hz adaptive. The adaptive sync, which sends the refresh rate to match the rate of the content, enables a smoother viewing experience, especially while watching fast-paced sports or action sequences.
While the 'refresh rate' seems like a simple concept, its importance cannot be overstated. Here are key metrics manufacturers consider to determine a TV's performance:
•
Refresh rate<\b>: Refers to how many times a display updates its image per second. It varies from 50Hz to 480Hz with higher numbers indicating smoother refresh.•
4K resolution (3840 x 2160 pixels)<\b>: Measures a TV's vertical and horizontal resolution, impacting its ability to show detailed images.•
HDR (High Dynamic Range)<\b>: Refers to the contrast range from the darkest black to the lightest white, essentially depth impressions for colors and enhanced picture quality.•
Panel type<\b>: There are two types: LED and OLED. LED TVs combine an array of LEDs behind an LCD screen to produce images, while OLED displays use an organic compound that emits its light.
