The Video Electronics Standards Association (VESA) is introducing a new compliance test standard and logo program to clarify the motion blur performance of digital displays, which is expected to allow consumers to easily compare the amount of motion blur.

VESA announced on the 23rd that it is introducing the 'ClearMR Compliance Test Specification' as an industry standard and logo program that provides new quality indicators for judging motion blur performance in digital displays.

ClearMR applies to both LCD and emissive display products, including display panels, TVs, monitors, and computers with built-in displays (all-in-ones, laptops, notebooks, tablets).

Clear Motion Ratio (CMR), a new metric defined by the ClearMR standard, allows consumers to easily compare the amount of motion blur across VESA-certified ClearMR display products by numerically clearly representing the ratio of sharp pixels to blurry pixels.

MPRT (Motion Picture Response Time) and other blur characteristic indices do not accurately reflect the intrinsic characteristics of blur, so CMR replaced these indices. />
“With the introduction of ClearMR, VESA is providing a clear, open standard that will make it easier for consumers to determine if the TV, notebook or monitor they are purchasing has the appropriate blur characteristics,” said Dale Stolitzka, senior scientist at Samsung Display’s America R&D lab and lead contributor to ClearMR. “With VESA’s ClearMR standard and logo program, consumers can now be confident that the display they are purchasing will display dynamic motion clearly and deliver the best possible viewing experience.”

Current techniques such as MPRT do not accurately reflect blur characteristics because time-based metrics alone cannot account for and evaluate multiple image enhancement and blur mitigation techniques, such as excessive overshoot and undershoot, which can cause artifacts or distortions that negatively affect image quality. VESA's ClearMR standard and logo program restricts the use of these enhancements in testing, allowing consumers to fairly compare motion blur quality across VESA Certified ClearMR displays.

The VESA Certified ClearMR logo defines performance grades from ClearMR 3000 to ClearMR 9000. The numbers here represent blur performance levels, which represent the ratio (percentage) of sharp pixels to blurry pixels. For example, ClearMR 7000 means that there are 65 to 75 times (6,500 to 7,500 percent) more sharp pixels than blurry pixels in terms of CMR. Therefore, each numeric grade represents a visually distinct difference in sharpness. The higher this CMR number, the higher the image quality and the less blurry it is. Only displays that pass all ClearMR compliance tests can display the VESA Certified ClearMR logo.

“By working together as a display industry to more accurately quantify motion blur, consumers will have an easier time choosing the right TV, monitor, and laptop display,” said Lee Ho-joong, head of the mobile display product planning team at Samsung Display. “We applaud VESA’s efforts to globally standardize the CMR metric with ClearMR. Our company fully supports this standard, and our latest OLED display products have already received this certification.”

“With the gaming market growing rapidly and VESA’s announcement of the ClearMR standard, we expect to see more innovation in gaming monitors,” said Jang Seok-ho, head of IT Development at LG Electronics. “The LG UltraGear™ brand was designed with this standard in mind early on, and the LG UltraGear™ 48GQ900, 32GQ850, and 27GP850 models are the first monitors to receive the VESA Certified ClearMR logo program certification from a VESA Authorized Test Center. LG will continue to work with VESA to ensure that our monitors not only meet the high standards required by VESA’s performance testing standards, but also meet the expectations and diverse needs of today’s consumers.”
