I can´t really see vertical line on the picture. If you still have warranty, RMA the laptop

try reinstalling the GPU drivers from Dell´s support homepage
Thanks for replying,
Those Lines are not much visible unless I increase the brightness on black color display and not at all visible on other colors display, I have tried reinstalling graphics drivers but it won't work, I am concerned for the display if there is an issue with that or it may be just some issue with display cable.
