Resolution issue

[David Marten]

I am having a problem with the resolution of a monitor using the DisplayLink technology. The device is from StarTech and is the USB32DPPRO which looks like it uses the DL3500.

I had an HP ZR30W monitor and was able to display at 2560x1600 with the USB32DPPRO. I have gotten a new monitor, a HP Z30i which can be driven at 2560x1600, however when connecting to the same USB32DPPRO the maximum resolution is only 1920x1200.

I have updated both the USB3.0 drivers from Intel and have the latest DisplayLink drivers from the DisplayLink webpage.

Any ides why I can use a higher resolution with an older monitor, but the newer one is limited?

thanks
