I haven't assembled a new PC in years, so please forgive any confusion. I'm setting up a fresh system and connecting peripherals, including my monitor (Asus ROG XG27ADQMG, 1440p 240hz) via DisplayPort on the CalDigit. I use this hub to switch between my new PC and my MacBook. My goal is to link the CalDigit to my PC through the Thunderbolt 4 port from the CalDigit to the USB4 slot on my motherboard. Currently, I own an Asus SOG STRIX x670E-I, but I'm thinking about upgrading to a Gigabyte model mentioned in the title because both motherboards support Thunderbolt 4 certified ports (the Asus uses Intel JHL8540, while the Gigabyte uses ASMedia ASM4242). The Gigabyte is more affordable. My concern is whether connecting the CalDigit to my motherboard will make the monitor use the CPU's iGPU (9800x3D) instead of my GPU (4070 Ti Super). I've heard potential problems with this setup, and some boards like the ProArt X670 have a DisplayPort IN that routes GPU signals directly to the dedicated GPU. Others don't specify this clearly. I was hoping to know what happens in this scenario. If not, my original plan was to retain the Asus because it has two USB4 ports that also function as DisplayPort Alt Mode ports, allowing me to connect a DisplayPort to a USB4 port on the motherboard and then use the other port for the CalDigit. Thank you ahead for your assistance!
