Ich versuche den Speicher von alten Grafikkarten abzufragen und so wie es aussieht, reicht die Typenbezeichnung nicht aus um den besten Kompromiss zu finden, zB

Andere 2. Grafikkarte:

Gibt es dafür einen Befehl um den Speicher der Grafikkarte abzufragen?
Aus der Sicht des Betriebs mit einem UHD-Monitor scheinen beide gleich schlecht geeignet, oder?
Interessant ist bei gleichem 32"-UHD-Monitor, die unterschiedliche xrandr-Ausgabe.
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 8192 x 8192 Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 16384 x 16384
Die 3. Grafikkarte scheint besser zu sein

Sieht so aus, dass diese Grafikkarte mit UHD zurecht kommt, aber nur bei 30Hz.
