I have a computer hooked into my TV and surround sound, every time I turn either one off then on again it negotiates 4k instead of the 1080 I require. How do I lock in screen resolution regardless of

I think that the telling diagnostic here is that in an otherwise identical setup, for a single-monitor system and the old HP monitor type, you replaced one monitor that worked with a supposedly identical one, and that second one did not.

That's highly suggestive of those two monitors no longer being identical, where once they were.

Do they send the same EDID/DisplayID information to the system?

Have you configured any EDID overrides for the kernel, with custom EDID files?

When you bring up the monitor's own OSD, what does it say about itself?

Кому‑чего-куда‑зачем: бесподрывный коммутатор “Ивента БВК44”

Раньше, в эпоху аналога, людям хватало терпения даже на то, чтобы вручную менять слайды в проекторе. Сегодня, когда все в цифре, « картинки » просто обязаны меняться плавно, без лишних телодвижений с нашей стороны. Однако мир не совершенен, и без помощи все равно не обойтись. Уточняем, чего это стоит, и кто помощники.

#ProTip

Pour identifier le modèle d'un écran¹ depuis une machine #GNULinux.

Cas d'un écran branché en HDMI

cat /sys/class/drm/card0-HDMI-A-1/edid | parse-edid | grep -C1 ModelName

Ça fonctionne aussi avec les écrans internes de laptop
/sys/class/drm/card0-eDP-1/edid

Mais l'#EDID a tendance à être moins bavard (Identifier/ModelName vide)

1. Par exemple si c'est pas écrit, effacé par le temps, peu lisible (contraste texte/boitier), écrit en tout fin sur l'étiquette à l'arrière de l'écran...

Lulz… Un écran d'appoint/portable 15.6" 1092×1080 pas cher dont le fabricant prétend une couverture 100% du sRGB en jouant sur l'ambiguïté 72% NTSC¹ soit 8 bit par couleur, stocke les infos #EDID pour déclarer une profondeur de couleur 12 bit par couleur (36/3) 🤣.

De même que pour les #eMarker #USBC les fabricants mentent comme des arracheurs de dents…

#marketteux

1. Même nombre de couleurs qui 100% sRGB sauf que c'est pas lis mêmes couleurs. Les écrans certifiés 100% sRGB sont plus chers…

Has someone here the capability to easily edit #EDID files?

I have an EDID file and want to remove all monitor modes except one.

I bought myself a little 5.5" control #display for my future #youtube and #peertube videos. A Feelworld F5 Pro with a native 1080p resolution.
Unfortunately, my #linux workstation running #archlinux only detects the display properly every fifth time. All the other times it shows up as a 640x480 unknown display.
I am connecting it to my computer via an AMD WX7100 GPU and a rather high quality DP to HDMI cable.
Any thoughts or do I need to go the route of injecting a fake #edid?
