I am running a new system I just build with a Sapphire 5770, connected to an Acer 1920x1080 23" monitor. Everything works fine when I use a DVI-D cable to connect the monitor to the system, but when I use a DVI-D cable, but when I use an HDMI cable it shows up psychedelic, like all kinds of purple and weird colors. Drivers are what came on the CD with the card and the mobo. Any ideas?

double check, make sure the cable is properly inserted. Or u can try with another cable if u have a spare...
