After BIOS no VIDEO output

[LB_KulGery]

Hello,

I reinstalled the computer with Win10, and then I wanted to update the BIOS.

So I went to HP Driver page, downloaded the HP Support Assistant.

I pressed download on urgent BIOS update. And run it.

I pressed do it. Then BIOS start to flash.

After update my Monitor led signed no connection. I changed cable to DVI, but no connection on DVI too.

I connected to PC with Teamviewer, and PC runs well, only with small screen.

How can I get back the VIDEO output? Or how can I get back to factory BIOS?

I can execute programs, but the HP management software windows to big for the small screen.

And, when BIOS runs, I can't connect to screen with Teamviewer, so I must navigate as blind.

Please help me

I can connect with Remote Desktop too, and then bigger the screen, so I can use the HP Management softwares too.

I try to download older BIOS, and I found, the downloaded and installed BIOS not in HP Driver site:

The BIOS file on HP_Tools partition is MAN_A046.bin

But on website, with same serial number are this BIOSes:

Pro A0.50
Business A.27

ROMPaq A0.07

My PC is Business so I download it, and try, maybe better then HP Assintant...

The software says This BIOS is not compatible with this device...

But I write correct parameters, with correct type of PC...
