Just I now I seen the technical specifiactions of your model , and I found that dell released intel graphics driver 188.8.131.5236 ,A04 and for NVidia graphics driver
184.108.40.20625 ,A12 .
But I found old intel version 220.127.116.1108 installed and also NVidia generic version 18.104.22.1685 you installed .
so I would you recommend install the drivers from dell .
Before installing driver , uninstall those completely by using revo uninstall software , then install both the drivers
the intel driver you specified is for 500,p500,600 and p600 series but mine is 630. when installing the system gives a error saying that it does not meet the minimum system requirements
morning I seen same page , you can find these sentences on that page

yeah, i tried to unistall intel graphics driver through revo uninstaller but couldn't find so i uninstalled through device manager also removed nvidia graphic driver through revo uninstaller and then installed the latest intel graphic driver driver but i couldn't find control pannel and also i can see gpu0 in task manager saying intel hd 630. but there is no control pannel and in display setting it says display1 connected to microsoft basic display adapter. at this time nvidia was not installed if i install nvidia graphic driver, it says display1 connected to nvidia...
also the hot keys are disabled, like i have a key to switch between integrated and dedicated graphics , dat key no longer works properly, but my nvidia dedicated driver is working properly.
thank you...my problem got solved , i unistalled the nvidia driver and used the key(i/d gfx) to switch from microsoft basic display adapter to intel hd graphics and then installed nvidia, now everything is back to normal
