Im using 2014 laptop Asus ROG G550JK with integrated graphics Intel HD 4600 and i want to connect it to new LG 27UK650-W 4k monitor. Using CAC-1170 adapter I cant get 3840×[email protected] but it works on 30hz. If i use custom resolution option and set it to 60hz, then screen just stays black and then reverts it back to 30hz. Whats interesting is that i can get 3840×[email protected] with my samsung 55KS7000 tv. Maybe need to update adapter firmware or its hopeless with his monitor?
