[zevlik12]

Hello,
I buyed new PC. Everything work excellent, connect in tv (monitor) with HDMI cable.
But my wife " me out from tv" and i need use my old monitor, what have just VGA input. I buyed everything needed to connect that vga in HDMI. But when I connect it into my graphics card it’s show “check signal cable”
On other pc working well, just on that not working.
Maybe somebody know if possible to tirn on VGA on motherboard even when is GPU in.

the onboard graphics ports get automatically disabled when an addon graphics card is detected.
I don’t believe you have any control over that.
so NO, the onboard VGA port can’t be used unless you remove the GPU.

Some but not all boards will allow the onboard video ports to be switched to the primary but the CPU must have on die video for the MBs video ports to work.
