Our sustained measurements are the lowest the brightness dips in a 3 minute span. Unfortunately, we don’t have any data on longer term sustained brightness.
Hi,
I have a question about the following description:
“We measure the SDR sustained window with the same test images as the SDR peak window, but the only difference is that we test for brightness after the window has been displayed for a few seconds.”
Is this ‘sustained’ period standardized in some way? How many seconds is it? I really want to know which displays have zero reduction in measured luminance, even over longer time scales (upwards of 10-20 minutes), but not sure if this information is available?
Thanks!

Hi, I have a question about how SDR Peak brightness is measured.
You mention you are using a PC to measure peak brightness on a TV.
Do you measure the 109% peak white (RGB value 255) or the video level at 100% (RGB value 235)? I believe these may differ slightly on some TVs regardless of the video range setting.
Good question! We set the PC to output in YCbCr422, which is always limited, so 16-235 RGB.

Hey RTINGS guys, you’ve updated the HDR video a few years back, right? Any plans to update the SDR video, or is it staying as is?
Hi James_92,
Thanks for reaching out with your question!
That’s correct, we’ve changed our HDR Brightness test by adding three HDR real scene tests in Test Bench 1.7 back in 2022. As of now, we don’t plan on reworking our current SDR Brightness test, though we may do so if a need to arises in the future.
Out of curiosity, what improvements or changes do you think our SDR Brightness test could benefit from?
Correct, the total run time is 3 minutes. Some TVs will stabilize before the 3 minute mark, but we still run it that long.

when i refer to your previous comments, sustained measurements for G5 around 2minutes. but you measured total 3 minutes, am i correct??
