Hallo zusammen
Ich habe ein Mainboard mit 1* HDMI, 1* Display Port, 1* VGA und 1 * DVI und zwei Monitore Dell UU2715H mit 2 K Auflösung und die Monitore werden in der Systemsteuerung angezeigt. Ich schliesse die Monitore über HDMI und ein Kabel von Displayport auf HDMI an. Der Monitor am HDMI-Port hat die Auflösung von 2560x1440 und der Monitor am Displayport 2048x1152. Im MEnue habe ich die höhere Auflösung nicht zur Auswahl. Wenn ich den zweiten Monitor direkt über ein Displayport-Kabel anhänge erhalte ich am Monitor kein Signal. Ich habe zum Testen eine ATI Raedon 5770 XT eingebaut und die neuesten Treiber geladen. Leider mit dem selben Ergebnis. Kann mir jemand einen Tipp geben?
Danke und schönen Jahresanfang
