RESOLVED: Unable to display native resolution
 

I had an issue where I was unable to display my monitors native resolution. It was stuck (and grayed out) at 1280x1024 when I needed 1440x900. DisplayLink software was unable to detect that was a supported resolution.


Here's how I resolved it:
This is on Windows 7 x64 btw.

DL Driver as reported from device manager: 5.2.21746.0
1: Right Click on DisplayLink Manager icon from system tray
2: Left Click Advanced
- This brought up the screen resolution window from windows 7
3: Selected the display link monitor -- this was forced to an incorrect resolution
4: Click Advanced settings off to the right
- This brings up the video card properties -- in my case a ATI Radeon HD3200 mobility
5: Under the Adapter tab, I clicked the button on the bottom left labeled "List All Modes"
6: Here I changed the setting from 1280x1024 (which is also what Display Link was forced to) to 1440x900.
7: Click all the OK buttons to get back to the resolution screen

Correct resolution was now available.

This worked for me to!
In step 5 my box was greyed out, I went to monitors tab and unchecked (hide modes this monitor does not support) the native resolution became available.

Thanks for posting your fix bchow!
