Mine has integrated graphics plus a dedicated card that it will switch to for higher demand applications. I was not aware of USB to HDMI, I’ll check that out. I don’t game when docked, so I only need the integrated graphics for that purpose. If that resolves my issue for now, I can put off a new purchase until I feel spendy enough to buy one of those Framework laptops!
In games that don’t have good auto-save (like Skyrim), I’ll map one of the back buttons to quick save.
