USB dock won't support 1920x1080 resolution


#1

Hi,

I just bought your USB docking station to replace a Kensington unit that died. The Kensington unit supported full 1920x1080 resolution on my external monitor, an Acer 27". I can’t get this resolution with the Plugable docking station; when I go into Control Panel and select Display, Adjust resolution, the highest option I see is 1680 x 1050. This happens with both DVI and RGB connections to the dock.

Any idea how to fix this? BTW I am running Win 7 Pro 64 bit and I downloaded the latest drivers for the dock.

Thanks,

Hi Bill,

Thanks for posting! Since the DL-165 chip in the Plugable Docking Station UD-160-A does support the 1920x1080 resolution, this is highly unusual.

Could you post back with the model of the Acer monitor that is connected through the Graphics port of the Plugable Docking Station UD-160-A?

Sure, it’s Acer B273HU. As I mentioned, the Kensington DisplayLink docking station I had before supported the higher resolution with this monitor.

Bill,

Could you run the DisplayLink support tool (instructions here: http://plugable.com/support/displayli… ) and email the .zip to support@plugable.com? This would give us a better insight as to what is going on.

Thanks for your patience while we figure this out!

OK, I ran this and sent the ZIP file to that address. Please let me know what you find out.

Bill,

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.

Thanks. I can confirm that the Kensington unit runs at 2048x1152 on my monitor.

I will return the product. Thanks for your help.

Hi, one more question: I am still looking for a replacement to the Kensington unit I have, which freezes several times a day. I see that Lenovo has a product called VDK8726, which looks a lot like your UD-160-A. Is it the same product rebadged, or does it have different specs?

Thanks again,

  • bill.

Bill,

The Lenovo VDK8726 has the same DisplayLink DL-165 chipset inside and hence you would not be able to set the resolution greater than 1680x1050 with the Acer B273HU monitor while connecting through it.
