Time to replace the screen.  If the system is under warranty, call Dell for replacement. If not, [URL]  
My laptop works fine, and i have image on an external TV via HDMI port, BUT, the main screen is almost black, just shows a line on top, like all the image was compressed on it.  How can i fix it?  It's a Dell Inspiron 3505 P90F, Ryzen 5, with Windows 10 Home (21H2)
