How to switch default monitor in BIOS?

Question

Iron

There is a laptop ASUS K95VB. On board are two video cards Intel HD Graphics 4000 and NVIDIA GeForce GT 740M. The laptop is mainly used as a system unit (for web development, without claims for 3D). A monitor is connected to the laptop and it is used as the main device (the laptop lid opens, the laptop turns on, the lid closes, then work from a large monitor).
Yesterday (possibly after the OS / firewood updates), the external monitor suddenly began to consider itself the first, and the laptop monitor became the second (although in Windows it is determined by the first laptop, and the external second). That is, when the laptop starts, the BIOS and all information until Windows is fully loaded is displayed on an external monitor. If an external monitor is not connected, then the laptop screen shows a black rectangle until the OS is loaded.
Thus, it is extremely difficult to enter the BIOS from a laptop or, for example, choose to boot from other devices.
How to switch back so that the laptop monitor is the first and main one?
PS
Everything works fine, the modes are kept on both the laptop and the external one, I reinstalled the firewood, rolled back to the previous version. The laptop monitor and VGA-connector and HDMI-connector also function.

Answer 1

Look in the settings for something like "Primary video port" or "Use monitor/output on boot" and set it to "LCD" or "Integrated LCD".

Answer 2

If you are talking about BIOS, then there is only the amount of allocated memory for IntelHD about the video. There are no other options. If it’s about firewood, then I won’t find it anywhere ...

Answer 3

If there is no item, just reset the bios to default. The default should be the laptop monitor.

Answer 4

Sorry, I have a question, although it’s not my topic, but I didn’t want to create a new topic, because in my case it’s the other way around ... I’ll start by saying that I broke the monitor, or rather the matrix ... Notebook model SAMSUNG NP300-E7A. In general, nothing is visible and I had to buy a monitor and used the laptop as a home laptop and removed the lid altogether. In short, the problem is, a black screen until WINDOWS boots up. That is, full priority does not go to the second monitor. And I need to reinstall the OS and I can't see the BIOS because it's a black screen. I searched the Internet, without results. Comrades, help, advise something ... I'm in despair (( Urgently need to reinstall ... Thanks in advance!
