Display

I replaced the display on the Dell Latitude 9420, the scale changed, instead of 100%, 150% was recommended, and the frequency, instead of 1920x1080, became 1920x1200. The picture has become worse, the resolution and contrast are visually worse. How to order and where to buy the screen of the initial configuration of the laptop, namely: 9C7CC : MOD,LCD,14.0FHD,NTCH,AUO,9420S 
2WGY7 LCD,14.0,FHD+,NEWFLANGE,AUO
 522V0 INFO,SWSI,LCD,14.0,NON-TCH
 6P59H SRV,FISH,OS,20H2,ADAC,FHD,9420
 CHH7F INFO,SWSI,NB,STD,LAT,9420

This system had either FHD+ (1900X1200) or QHD screen (2560X1600).  It did not have a 1920X1080 resolution screen.

You have the correct resolution if your system shipped with the FHD+ screen.

It may be the replacement screen has different characteristics from the original, but if you want the same panel you had originally, it's this one:

@ ejn63 Thanks for the useful information! I figured out the screen resolution, I agree. But why is the scale 150%, probably this display is for another model (B40GFT01.0 *NL0N6089Y0JB-ZK0170*)? Also, thanks for the link to the original panel.

Whatever scaling is applied is set at the operating system level -- if it doesn't look correct, return it to 100%.

Right click on the desktop and go to Display Settings to reset the scaling.
