I'm trying to figure out the characteristics of the display on my Asus Vivobook S notebook. One way to figure this out is to look at the monitor's EDID (Extended Display Identification Data). I installed a program called edid-decode since otherwise the EDID is just binary bytes. Then I used this command: edid-decode /sys/class/drm/card1-eDP-1/edid | less The path is to one of the edid's exposed by the Linux kernel. I picked eDP because that should be the built-in display. I've included to result at the end of this message. Things I noted - manufacturer is SDC (Samsung Display Company) - manufactured in the 25th week of 2021 (older than I thought) - bits / color channel: 10 (very nice) - only color format: RGB 4:4:4 That means no chroma subsampling but RGB doesn't support chroma subsampling anyway ================ EDID ================ edid-decode (hex): 00 ff ff ff ff ff ff 00 4c 83 6d 41 00 00 00 00 19 1f 01 04 b5 1f 14 78 02 0c f1 ae 52 3c b9 23 0c 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 39 ff 40 5c b0 08 20 70 14 20 08 04 38 c3 10 00 00 1b 39 ff 40 5c b0 08 48 77 14 20 08 04 38 c3 10 00 00 1b 00 00 00 0f 00 ff 0a 78 ff 0a 3c 28 80 02 00 00 00 00 00 00 00 fe 00 41 54 4e 41 34 35 41 46 30 31 2d 30 20 01 72 02 03 0f 00 e3 05 80 00 e6 06 05 01 74 60 07 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 b7 ---------------- Block 0, Base EDID: EDID Structure Version & Revision: 1.4 Vendor & Product Identification: Manufacturer: SDC Model: 16749 Made in: week 25 of 2021 Basic Display Parameters & Features: Digital display Bits per primary color channel: 10 DisplayPort interface Maximum image size: 31 cm x 20 cm Gamma: 2.20 Supported color formats: RGB 4:4:4 First detailed timing includes the native pixel format and preferred refresh rate Color Characteristics: Red : 0.6796, 0.3203 Green: 0.2373, 0.7226 Blue : 0.1396, 0.0498 White: 0.3125, 0.3291 Established Timings I & II: none Standard Timings: none Detailed Timing Descriptors: DTD 1: 2880x1800 120.001014 Hz 16:10 219.842 kHz 653.370000 MHz (312 mm x 195 mm) Hfront 20 Hsync 32 Hback 40 Hpol P Vfront 16 Vsync 8 Vback 8 Vpol N DTD 2: 2880x1800 60.000507 Hz 16:10 219.842 kHz 653.370000 MHz (312 mm x 195 mm) Hfront 20 Hsync 32 Hback 40 Hpol P Vfront 16 Vsync 8 Vback 1840 Vpol N Manufacturer-Specified Display Descriptor (0x0f): 00 0f 00 ff 0a 78 ff 0a 3c 28 80 02 00 00 00 00 '.....x..<(......'
