monitor driver

i have a hp elitebook 745 G^ ryzen pro. i put a monitor on it an mtg24 that i was told was a dell monitor. i got the monitor set up and for one it is a bit fuzzier than the dell 24" i took off. the one i took off is about 4" thick and that took up a lot of room on this desk. so i got this mtg24 and flipped it over and built a stand so i can tuck the laptop screen up and under the back of it. anyway this mtg24 monitor is a bit fuzzy from the other dell and the resolution is not what i can use. the pc says it likes 1920x1080 but then the image is so wide the desktop icons are way off the screen on the left side and the task bar is so far down i can just about see it.  i tried ever resolution and none see to fit this monitor. if i get one that looks good i lose both side of the screen to nothing. i can't have that either. so if i can't get this to show a good screen so everything is able to bee seen it is junk to me. i think it is a driver but in device manager when i ask for a driver it say the one i have is

this is the dell 24" i took off if you need the numbers for the one i'm asking about this is the info on ebay now this may not be a dell but when i type in mtg24 dell came up. so if anyone knows when it is and where to get a driver please let me know. thanks

correct.
