[SOLVED] Will it work...

Hello

Will the usb c connection on my b450 run a 1440p 165hz monitor? It if will how much performance would I lose? Thx

I do not think your USB-C will transfer video. Why would you even want to do such a thing?

 

[Math Geek]

considering that is a mobo connection, that means it would only be able to ouput a signal coming from an igp of the cpu (if it is even capable of outputing a video signal which is highly unlikely). and none of those are even close to capable of pushing 1440p for anything but office work.

your discrete gpu is what would push such a monitor and that is what you want to worry about what connections it has.

The answer is no.

Your board has 2 x USB 3.1 Gen 2 port(s) (2 at back panel, red) that should be able to push
AMD Ryzen™ 2nd Generation/ Ryzen™ with Radeon™ Vega Graphics/ Ryzen™ 1st Generation :
AMD B450 chipset :

You are running a Ryzen 7 3700x which has no integrated graphics. So even though the port is hypothetically able to support up to 4k, with the right cable, the right monitor that can support the cable and the right CPU, you lack the integrated graphics on the cpu to drive said port. Even then it would only be for the integrated graphics which would be very questionable at anything over 1080. And most monitors don't support the connection for USB. Some will have the USB c for thunderbolt support but the USB protocols would have to be supported.
