BIOS screen not showing on HDMI

bhupesh

I have a SER 5th Generation Pro Mini PC. The BIOS for that does not show up on HDMI display. Only shows up on DP. How can I make everything work on HDMI only. Thank you.

Hello there,

Could you please send us a picture of  SN code at the bottom of machine ?

You can try to clear CMOS firstly: First,please unplug the power supply and HDMI cable.
Please press the pinhole of "CLR CMOS" with a pin for about 10 seconds.Ten minutes later, plug the power supply and HDMI cable, turn on the PC again.  
Please wait about one or two minute, if you can go to the system.
Please repeatedly press delete key as soon as your restart the PC, go to BIOS. Go to Boot option, enable fast boot, press F4 to save.  
Here is the tutorial https://mega.nz/file/2nIRGaYI#M2 ... pfyHlqyjnn86TypZp2w  

May I ask whether the Windows interface can be normally displayed on the HDMI interface connected display？

Have a nice day!

Windows work correctly on the HDMI interface. Clearing CMOS did not help. The Splash screen does not show and even if I hit delete, the BIOS menu does not show. If I don't do anything, Windows boots fine and displays fine on HDMI. Everything other than the initial boot screen and BIOS screen works fine on HDMI. Attached is the SN screenshot.

Hi there
if you use 2 monitors .
one is main screen another is second monitor.
for second monitor it will only appear when it comes to the system .
vice versa
you can check the display setting in the windows ,
see if you can get HDMI as main screen . if you want .
