The Radeon HD 6310 graphics card does not display an image until Windows XP is loaded. How to find the reason?

The bottom line is this: the computer has a multi-boot menu from Windows 7 (bootmgr), through which you can get into Windows 7 or Windows XP.
Starting from the moment Windows XP is selected in the multiboot menu, the image on the monitor stops being displayed until the XP's video card driver is loaded. Moreover, it does not just stop being displayed, but "hangs" the monitor: it is clear that the screen has not turned off, but the monitor does not respond to buttons (menu, etc.). Sometimes it shows some pale light spots in random places.
If you turn it off and on at this moment, there will be colored bars on the screen. You can enter XP's boot mode selection menu (secure, etc.), but it is not displayed.

At the same time, after logging in and loading the drivers, the image is normally displayed without defects. During the boot process of Windows 7, everything is displayed as it should, no defects.

What could it be? Problems with the drivers installed in the system are excluded, because. defects appear before they are loaded. All this is somehow related to the video drivers embedded in NTLDR, and it doesn’t look like hardware problems (everything works at the same resolutions when loading Windows 7).

Recently this problem manifested itself on another computer with the same monitor. On the other monitor on the original system unit, everything is fine. This appears on some computers that have UEFI instead of BIOS.
That is, a combination of three factors causes the problem:
1. UEFI, even if legacy boot mode (MBR) is enabled in it.
2. Windows XP, or rather its bootloader - ntldr. On Windows 7 with its bootmgr, this problem does not exist.
3. Monitor. With a combination of the first two factors, he cannot normally display the signal coming to him from the computer.
In general, the problem has so far been solved by replacing the monitor.

Perhaps the problem is in the order of loading the drivers?
Look in the registry to see what priority your video card driver has.
Here is some theory

Perhaps the video card selects a different port for output. For example, you connected to HDMI, and it outputs to D-SUB, or vice versa.
