xrandr - comment trouver la commande de sortie spectre complet RVB correcte pour mon système

Question

Je viens de brancher mon ordinateur portable à un moniteur externe après un "incident de débordement" qui a masqué l'écran intégré. Cependant, lorsque je connecte le moniteur via un câble HDMI, les couleurs semblent extrêmement délavées. J'ai cherché un peu autour et j'ai trouvé que c'était probablement dû à la carte graphique de l'ordinateur portable ne produisant pas tout le spectre RVB via HDMI par défaut. J'ai trouvé une solution ici:

https://www.kubuntuforums.net/showthread.php?63895-Black-level-too-high-after-upgrade-to-13-1

recommandant cette commande:

xrandr --output HDMI1 --set "Broadcast RGB" "Full"

qui ne fonctionne pas sur mon système, car les paramètres ne sont pas applicables:

output HDMI1 not found; ignoring X Error of failed request: BadRROutput (invalid Output parameter) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 15 (RRGetOutputProperty) Serial number of failed request: 28 Current serial number in output stream: 28

Iran:

xrandr -q

et la sortie:

[...] HDMI-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 160mm x 90mm 1920x1080 60.00*+ 50.00 59.94 30.00 25.00 24.00 29.97 23.98 1920x1080i 60.00 50.00 59.94 1600x1200 60.00 1680x1050 59.88 1280x1024 75.02 60.02 1440x900 59.90 1280x960 60.00 1280x800 59.91 1152x864 75.00 1280x720 60.00 50.00 59.94 1024x768 75.08 70.07 60.00 832x624 74.55 800x600 72.19 75.00 60.32 56.25 720x576 50.00 720x480 60.00 59.94 640x480 75.00 72.81 66.67 60.00 59.94 720x400 70.08 VGA-0 disconnected (normal left inverted right x axis y axis)

m'a fourni le paramètre correct --output, HDMI-0. Cependant, je ne sais pas comment trouver une liste de paramètres et de valeurs applicables sur mon système lors de l'utilisation de l'indicateur --set, afin de pouvoir déterminer ce qu'il faut utiliser à la place de "Broadcast RGB" et "Full". Pour le moment la commande:

xrandr --output HDMI-0 --set "Broadcast RGB" "Full"

les sorties:

X Error of failed request: BadName (named color or font does not exist) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 11 (RRQueryOutputProperty) Serial number of failed request: 29 Current serial number in output stream: 29

J'ai aussi couru Sudo lshw -c video:

*-display description: VGA compatible controller product: Mullins [Radeon R4/R5 Graphics] vendor: Advanced Micro Devices, Inc.

Mais ne pouvait rien trouver qui semblait immédiatement utile dans les informations résultantes.

J'ai aussi lancé xrandr -v qui affiche:

Pour le moniteur/connexion concerné.

Si cela n’était pas possible avec xrandr, je serais également disposé à accepter toute réponse me indiquant comment récupérer des données et manipuler la sortie de RandR/X11 via une méthode différente.

George · Answer

La propriété Broadcast RGB concerne les cartes graphiques Intel. output_csc semble être la variante AMD de la même chose.

output_csc est défini sur bypassdans ce que vous avez publié, ce qui devrait être équivalent à la plage Full(0-255).

Vous pouvez essayer de définir output_csc avec d'autres options valides, notamment tvrgb(16-235).

xrandr --output HDMI-0 --set "output_csc" "bypass" xrandr --output HDMI-0 --set "output_csc" "tvrgb" xrandr --output HDMI-0 --set "output_csc" "ycbcr601" xrandr --output HDMI-0 --set "output_csc" "ycbcr709"

Il est également possible que certains paramètres de votre moniteur doivent être modifiés.

Vous venez de rater un tiret "-" entre HDMI et 1

xrandr --output HDMI-1 --set "Broadcast RGB" "Full"
