Windows 10: Video card, monitor or Windows 10 at fault?

I have a GTX1050 video card, LG 27" 4K monitor at 3840x2160 (scaling 175%) and am running Windows 10 CU. If I switch the monitor on NLT a few seconds after the boot beep, everything is fine when Windows opens and I see the desktop. But if I wait longer to switch it on, icons are shrunken and my custom font settings have reverted to Windows default. Rebooting cures the icon size problem, but I have to run the .reg file I made for font settings and reboot again before that's fixed. Any ideas why the Registry would change just because the monitor is late getting switched on?

Will win 10 recognize my 27" full hd monitor from my laptop like Win 7 does?

That's a good question. Windows doesn't know about your monitor. It sends video signals to your graphics card or chip, and the graphics card/chip takes it from there. The information Windows displays about your monitor, e.g., in Device Manager, comes from
the video subsystem.

Which is a long winded way of saying: If your video subsystem worked with your monitor in Windows 7, it'll work with it in Windows 10.

Therefore, the real question should be: Is my video card/chip supported on Windows 10?

 

Windows 10 Pro White Bar of Death?

Fixed...

I had to remove the dual monitor video card.

Power up using the old motherboard's video card and powered back down.

Then put the dual monitor video card back in the machine.

Powered up again.

All is good in the world again.

The switching between video cards seems to have forced Windows 10 to rethink something.

 

I have almost the same monitor, only difference is, I don't shut it off when I power down. I let it go to sleep
and don't have this problem. Have you tried that?

 

Thanks. I'm sure that would solve the problem. And the monitor consumes only 0.5W in sleep mode. Unless I can find a solution otherwise, that could be my best option.

 

Ya, don't think I've actually shut a monitor off since my old crt.
