m17 R3, screen replacement won’t work
I had to get a new screen for my m17 R3 and I got the correct pins and size. However, the specs or something isn’t exactly like it should be, so when I turn it on the screen stays black and I get the 3/2/1 beep. If I plug it into HDMI then boot, display on the external monitor works fine. Is there a way to configure bios to work with this screen? Please help

There's no adjustment -- either the screen works, or it does not.
There is more to compatibility than just the connector position and size -- notebooks very often depend on a table of EDIDs and will work only with those screens the manufacturer of the system (probably Compal) specified when it designed the system for Dell.
It is equally true that there could be another issue afoot -- a bad GPU can send a good signal externally where the internal one is faulty. It could also be a bad cable feeding the display or even a bad power supply to the backlight. What happened to the original display panel?
