First reported on Reddit, Zamundaaa replied to my post. Reply: "I added some safety checks to make sure the built in color profile is sane; maybe they're too restrictive. Please make a bug report for KWin about this, and attach the EDID of the screen there." Summary: By default, KDE Plasma uses "None", which in my laptop makes the colors appear undersaturated. In Plasma 6.2.5, I noticed that by using the option "Built-in" it made the colors appear normal compared to my iPhone. So after I upgraded to Plasma 6.3, I noticed both options look exactly the same. My laptop is Acer Nitro AN515-57. I tried looking for an ICC profile on the internet but I couldn't find it. On Fedora 41, running Wayland. I don't really know anything about EDID so I asked ChatGPT to provide commands to get it, so I think this is it: edid-decode (hex): 00 ff ff ff ff ff ff 00 06 af 90 af 00 00 00 00 08 1e 01 04 a5 22 13 78 03 3e 85 91 56 59 91 28 1f 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 34 8a 80 a0 70 38 64 40 6c 30 35 00 58 c1 10 00 00 18 dc 37 80 a0 70 38 3e 40 6c 30 35 00 58 c1 10 00 00 18 00 00 00 fd 00 3c 90 a5 a5 22 01 0a 20 20 20 20 20 20 00 00 00 fe 00 42 31 35 36 48 41 4e 30 38 2e 34 20 0a 00 b5 ---------------- Block 0, Base EDID: EDID Structure Version & Revision: 1.4 Vendor & Product Identification: Manufacturer: AUO Model: 44944 Made in: week 8 of 2020 Basic Display Parameters & Features: Digital display Bits per primary color channel: 8 DisplayPort interface Maximum image size: 34 cm x 19 cm Gamma: 2.20 Supported color formats: RGB 4:4:4 First detailed timing includes the native pixel format and preferred refresh rate Display supports continuous frequencies Color Characteristics: Red : 0.5664, 0.3388 Green: 0.3505, 0.5683 Blue : 0.1582, 0.1210 White: 0.3134, 0.3291 Established Timings I & II: none Standard Timings: none Detailed Timing Descriptors: DTD 1: 1920x1080 144.149283 Hz 16:9 170.096 kHz 353.800000 MHz (344 mm x 193 mm) Hfront 108 Hsync 48 Hback 4 Hpol N Vfront 3 Vsync 5 Vback 92 Vpol N DTD 2: 1920x1080 60.201401 Hz 16:9 68.750 kHz 143.000000 MHz (344 mm x 193 mm) Hfront 108 Hsync 48 Hback 4 Hpol N Vfront 3 Vsync 5 Vback 54 Vpol N Display Range Limits: Monitor ranges (Range Limits Only): 60-144 Hz V, 165-165 kHz H, max dotclock 340 MHz Alphanumeric Data String: 'B156HAN08.4 ' Checksum: 0xb5 I'm also attaching here the return of kscreen-doctor -o, in case it helps debugging: Output: 1 eDP-1 enabled connected priority 1 Panel Modes: 1:1920x1080@144*! 2:1920x1080@60 3:1280x1024@60 4:1024x768@60 5:1280x800@60 6:1920x1080@60 7:1600x900@60 8:1368x768@60 9:1280x720@60 Geometry: 0,0 1536x864 Scale: 1.25 Rotation: 1 Overscan: 0 Vrr: Automatic RgbRange: Automatic HDR: incapable Wide Color Gamut: incapable ICC profile: none Color profile source: EDID Color power preference: prefer efficiency and performance Brightness control: supported, set to 60% and dimming to 100%
