DRIVER REQUIRED DGM L-1931W MONITOR

Question

Good morning, I hope you are able to offer me some assistance. I have recently purchased the monitor above. The monitor is connected & working, however I cannot find the correct drivers to install so that I can obtain the best resolution for my monitor. At the moment it looks as though the settings for the old monitor are being used and the resolution is very poor. The icons are huge and most of the pages are off the screen.
