USB 3.0 Docking Station with 2560x1080 Resolution
I have been looking to connect my laptop to an LG ultrawide monitor (2560x1080 resolution). Because I want to use a single device to also connect an ethernet cable and several USB devices, a USB adapter is not a viable solution and because my laptop does not have a USB-C port, I need a USB 3.0 device.
Unfortunately, I have not been able to find one that looks like supports the 2560x1080 resolution (many will say "up to 2650x1440", but this does not seem to include 2560x1080). I am hoping that someone might be able to point me in the way of a device that will suit my needs. Thanks in advance for any help. |

Hello,
What matters is the pixel clock or data throughput: you have a pipe and the amount of information which can flow in the pipe depends on the pipe size, not how you rearrange the data afterwards (row x columns of an image). Pixel clock depends on the resolution, refresh rate and timings for the monitor. It's not convenient to list all the exotic resolutions that a panel manufacturer might wish to do, so instead, you have the most common ones listed. The amount of pixels is 2650x1440 = 3.816 Mpixels 2560x1080 = 2.765 Mpixels There is so much difference that the timing won't make a big difference in working/not working. But you seem to refer to the HDMI max resolution of a particular DisplayLink IC series. I would advise you use DisplayPort so you can get a higher refresh rate in all conditions if you use that series. Alternatively, you can use a product with the latest DisplayLink chip which can drive 4Kp60 on any output type (which standard supports it, of course) http://support.displaylink.com/knowl...rticles/525038 Kind regards, Alban
