issue with configuring displaylink

Hello,

I am not exactly a new user having been using Arch Linux for almost 2 years on my laptop. I recently bought 2 monitors and now I am trying to get those working with my laptop. I only have 1 HDMI port so I went for a DisplayLink USB to HDMI adapter for my second monitor. I followed the DisplayLink article on the wiki and have managed to install the evdi and displaylink packages. (the evdi-git package mentioned in the wiki did not build for me. I got the same error as mentioned in the comments).

I am able to see the monitors on Xrandr. Here's the output for the xrandr --current

xrandr --current

The issue I am facing is that my DisplayLink monitor is shown to support only upto 1024x768. The monitor is capable of 1920x1080. If I use the following command,

xrandr --output HDMI-1 --auto --left-of eDP-1 --output DVI-I-1-1 --auto --right-of eDP-1 --output eDP-1 --auto --primary

I get display on both the monitors but on the second one it's again low res. I have a dual GPU laptop with nvidia+intel setup. I have also tried to block nouveau but no success. Here is the output of my dmesg:

dmesg | grep udl
[    3.651205] udl 2-4:1.0: DVI-I-1: EDID invalid.
[    3.651629] udl 2-4:1.0: fb1: udldrmfb frame buffer device

I see here that the displaylink device is detected but it says that the EDID is invalid. Any pointers on how I can go ahead and fix this?
