I have three ViewSonic VA2431WM 24" monitors connected to a new Radeon HD 7850 running AMD Vision Control Panel version 2012.0806.1213.19931. The 3rd monitor is connected to the display port via a Accell UltraAV B087B-002B adapter. When first connected the 3rd monitor correctly auto set itself to 1920 x 1080 which matches what the other 2 monitors are running. A few hours later I went to bed and left the computer running and when I awoke the 3rd monitor is now incapable of that resolution but instead the maximum is 1600 x 1200. I have restarted/reconnected everything and updated the Accell adapter to the latest firmware all to no resolution. When I swap the connections around the issue follows the monitor on the display port (through the adapter) so I do not believe there is an issue with the monitor itself. 


Can you please recommend a course of action to get the 3rd monitor properly running at 1920 x 1080?

Sounds to me as though the adapter itself my have died on you.  Can you return (RMA) it for a new one?

Looks like EDID no longer passes through the right information.. you could try to force 1920x1080 as a custom resolution.. a workaround that may create even further issues. If that yields no results, get a new adapter.
