It seems to be the same I have.
It is 1920x480, I bought one form China at AliExpress for roughly 50 pound.

I used paint.net. Please bear in mind that I don't know absolutely nothing about graphics editing so don't expect too much from attached file. I have used paint.net like third time in my life bg.pdn
Thanks for sharing this.
I really like the blue panel and decided to make some adjustments to suit my config, also removed some chinese characters from the background.
