Received a 7275 today but cannot get the resolution to increase to 2560x1080 on my external ultra-wide. Unplug the HDMI and plug it into my old laptop. 2560x1080. The maximum resolution in the advanced settings are 1920x1080. Help.
Let me see if I can find anything to try on this, has anything changed since your post? Also can you Private Message me your Service Tag?
