Within about a minute of leveling at FL390; we noticed a smell. About 30 seconds after that; the Captain said he had smoke. I looked over and a lot of smoke was coming out of his PFD top left corner. We went on oxygen and established communication. I grabbed the QRH and ran 8.10. The smoke stopped about the time we got the utility busses off. We [advised ATC] and turned around for ZZZ. His PFD continued to do strange stuff so the Captain decided to pull the CB. After that; the smell started to dissipate and get better. We switched to me being Pilot Flying and landed without any further issues.
B767-300 First Officer reported smoke in the cockpit emanating from Captain's PFD. Flight crew ran the emergency checklist; advised ATC; and returned to departure airport.
