Verifying pixel encoding and rate support
For test IDs 8-19 and 8-20, visual inspection of display under test is necessary to ensure
proper support of pixel encoding sampling and minimum and maximum pixel clock rates
using different formats. Test ID 8-19 involves testing each format with both YCbCr 4:4:4
and YCbCr 4:2:2 pixel sampling, while test ID 8-20 requires testing each format listed in
the EDID at both minimum and maximum pixel clock frequencies permitted by the source
device. Pixel clock rate values are as follows:
•
For 50 Hz formats, the values are 49.75 Hz and 50.25 Hz (50 Hz ± 0.5%).
•
For 59.94 Hz or 60 Hz formats, the frequencies are 59.64 Hz (59.94 Hz – 0.5%) and
60.3 Hz (60Hz + 0.5%).
•
The tested pixel clock frequency accuracy shall be ±0.05%
To support this testing, a list of SVD formats are provided in the Source list. For
pixel
encoding testing, the format naming nomenclature used is shown below:
