[quote=frafra]Sento spesso problemi di EDID e di adattatori. Il mio primo pensiero è provare un adattatore differente (magari DP a DVI o DP ad HDMI).
Detto ciò, puoi dirci il risultato di questo comando?
$ xrandr --prop
È sicuramente un problema di EDID. Su alcuni forum, ho letto di chi ha risolto utilizzando parametri di EDID diversi da quelli forniti da cvt e ho tentato di fare la stessa cosa, purtroppo non ho trovato un documento con le specifiche corrette per il mio monitor (HP 23xi) e nemmeno utilizzando comandi come monitor-edid riesco a risalire ai parametri del mio schermo.
In ogni caso, ti posto l’output con la risoluzione settata a 1920x1080 e il monitor utilizzato per 3/4.
