i have an 6670 and i use 2 monitors. 1 connected to an vga splitter, that one is connected to my beamer and 1 monitor. the other monitor is connected on DVI. this port works perfectly but HDMI doesn't seem to work! i get a blue tint no matter what cable i use. the cable does work on other pc's so its the port. it came all out of the sudden. Can someone relate to this?
