So i recently bought a monitor to use with my laptop and connected it via the hdmi cable that came out of the box. But now I realise its still connected to the Intel Integrated Graphics instead of my GPU. Can someone tell me which port I should be using to bypass the intel graphics and if possible also suggest a good cable to buy.
