Hi, built a computer from Ibuypower with an AMD Radeon HD 6770 - 1GB Graphics Card. No display driver
installed to begin with as I installed Win 7 Professional 64 bit, so I installed the driver that the CD told me to with no avail. With an HDMI cable it goes through the BIOS and to the initial windows loading screen and then no input signal. Uninstalled via safe mode and installed catalyst 11.5 with nothing as well. VGA works, but I'd rather use the HDMI cable I bought for it.. Windows automatically installed Catalyst 11.2, I should problably update it, but that won't fix the HDMI problem.
Reading through various forums, the 6770 is essentially the 5770, but since you install catalyst and can't actually pick the 5770 driver I'm not sure how to go about this.
I had another computer about 10days ago with the same video card and HDMI worked fine with it (power supply blew up so i returned it and got a new comp). I had a pre-installed graphics driver on that one, any time I tried to update it failed like it is now.. but whatever driver was on it could use HDMI.
Anyone know how to fix this by chance?
