Thanks for sending us the DisplayLink logs! The logs report that-:
The EDID (Extended Display Identification Data) that was received from monitor ACR0091 (Acer B273HU) shows that the modes that the monitor supports are 640x480, 800x600, 800x600, 1024x768, 1280x720, 1280x800, 1280x960, 1280x1024, 1680x1050, 2048x1152. The native mode of the monitor is 2048x1152.
The DisplayLink DL-165 chip in our Plugable Docking Station UD-160-A does not support 2048x1152 resolution as it only supports resolutions up to 1920x1080. Since the monitor reports via the EDID that 1920x1080 is not a mode that it supports, the next highest resolution (1680x1050) supported by both the monitor and the DL-165 chip is set as the highest resolution that the user can set for this monitor via the Windows Screen Resolution Control Panel. So although the Plugable Docking Station UD-160-A supports a higher resolution of 1920x1080, Windows will not allow you to set that resolution.
The Kensington DisplayLink Docking Station that you previously had, has a DisplayLink DL-195 chip which supports the 2048×1152 resolution which also happens to be the native resolution of your monitor. We use the same DL-195 chip in our Plugable UGA-2K-A USB Graphics Adapter. If you connect this same monitor through the Plugable UGA-2K-A, you would be able to set the resolution to 2048x1152 when connecting through DVI.
As you would not be able to set a resolution higher that 1680x1050 when connecting the Acer B273HU monitor through the Graphics Port of the Plugable Docking Station UD-160-A, we totally understand if you would prefer to return the product.
