How to switch GPU

[Mr Scratch]

Hello, yesterday I installed Linux Mint for the first time on my PC, however I have a question regarding my GPU.

I use an old monitor that has only VGA output and for this reason I cannot connect the monitor directly to my graphic card (RX 570) so I connect it to the motherboard. In windows 11 there was an option that allowed me to use the RX 570 as the main GPU even though the cable was connected to the motherboard.

So my question is, is there any way to do the same in Linux Mint?

In windows 11 there was an option that allowed me to use the RX 570 as the main GPU even though the cable was connected to the motherboard.

Please explain what you think this means. Usually, the BIOS/UEFI settings are what determines which ports are connected to specific GPUs.

The data you posted indicates
1) Your system is not updated. Please run the updates available in Update Manager.
2) Your system is shows the RX 570 as the primary GPU. That is why it is listed as Device 1.

Are you using a VGA-HDMI cable? The GoldStar TV is showing as an HDMI connection and your RX 570 does show as having HDMI ports.
