1920x1080 resolution


#1

Hi,

The USB docking station is not supporting my LCD resolution of 1920x1080. I am using a Dell 2407.

Suggestions?

Thanks

Hi Jeremy,

Thanks for posting! Unfortunately, that would be expected with the Dell 2407WFP, because it has a native resolution of 1920x1200. Here’s what’s happening:

The Plugable UD-160-A (http://plugable.com/products/ud-160-a/) has a DL-165 chip inside. Because the DL-165 chip cannot do that 1920x1200 (its max mode is 1920x1080), the DisplayLink driver will fall back to the next mode offered by the Dell 2407 in its EDID information (See http://en.wikipedia.org/wiki/Extended… for more background on EDID)

On a 1920x1200 monitor, the next lower mode the monitor reports will tend to be the next mode with a similar aspect ratio (probably 1680x1050). Is that or something similar the mode its setting now?

Sorry for the bad news. So what can we do about it? Sticking with 1680x1050 means not taking maximum advantage of the monitor, but also has the practical advantage that you’ll not stress USB 2.0 as much, so you’ll see better and more consistent performance. So it’s actually a good option.

But you could also get up to 1920x1200. You just need to buy a device with the high-end DisplayLink 195 chipset in it, like our UGA-2K-A (http://plugable.com/products/uga-2k-a/)).

The UGA-2K-A can be connected to the dock, so you could use this as an excuse to add even more monitors: add a UGA-2K-A and a 1920x1080 or lower monitor, and you can use the UGA-2K-A for the Dell 2407WFP, and the new monitor directly to the dock, both extending your desktop.

I hope this background helps. Sorry for the bad news. Please let us know if you have any questions. And we’re happy to help get you to the right option that works best for your setup, all things considered.

Just let us know.

Thanks!
Bernie
