Can you get a video signal through UCB C? Or is hdmi necessary?

That’s my question, I need a video output to connect it to the main screen when I’m at home.

Is it necessary to buy the hdmi port? Or is two USB C ports (one to charge the battery and the other to connect to the screen) enough?

USB-C will output a DisplayPort signal. So with the correct cable you can go USB-C to DP or HDMI.

Note that only the rear-right, rear-left and centre-right expansion slots will support video output. This is regardless of whether you use USB-C or a dedicated display expansion card.

If you purchase the graphics module, that comes with its own display-capable USB-C port, seperate from the expansion cards.


Does the amd dedicated gpu come with a usb c port for video output?

So would another USB C port be enough for me to charge the laptop and I wouldn’t need the HDMI port or another USB C port? (since I would buy the dedicated GPU and another USB C port, one for charging and another for video output to the monitor)

Yes. There is a USB-C port on the back of the dedicated GPU module, which is for video output. But only video output, it’s not a full-featured port meant for other purposes. If I recall, you can’t charge the laptop using the that GPU port.

Yes. In fact it is recommended.

The ports on the laptop always connect to the iGPU (the GPU integrated into the CPU). When using the dedicated GPU and using a port on the laptop the dedicated GPU does most of the GPU work, however it hands off the the iGPU for the outputting through the port.

That handing off introduces a several percent performance penalty, which can be avoided if you use the USB-C port on the dedicated GPU.
