Precision 7520 with E-port plus II - No preboot screen.
I am using a precision 7520 (with a second GPU Nvidia Quadro M1200, apart from the Intel HD 630) with the E-port plus II. Unfortunately, there is no pre-boot screen on the display connected to the e-port. I have tried both DP and the VGA. The display starts, only when the OS has started. I tried to disable switchable graphics on BIOS, but nothing changed, still no pre-boot screen. Also, when booting with windows 10 the DP2 and the VGA works fine, but not DP1. When booting with Linux Mint DP1 works, but not DP2 and VGA. What should i do, to make the display connected to the e-port works as it should? Thank you,
Gommer

Try to activate legacy Bios or switch from AHCI to RAID (should be no problem in this direction, but for safety backup your data). Same issue was on 7510 and Dell published a modified Bios, for 7520 I still created a request.

Thank you for the answer but the switching to RAID is not an option.
With RAID I can't access from linux the disk where Windows 10 are installed. I have to find another solution.
