Just removed my old ATI HD 7950 and installed a new GTX970 (3975-KR) and have the following issue:
Problem: All display ports do not output video.
Setup:
3x ASUS VS239H-P monitors:
1x HDMI
1x DVI
1x DP --> HDMI cable (monitor verified good by using HDMI output)
Symptoms:
Windows & video card do not see DP monitor
Does not display video on BIOS or startup
Troubleshooting / additional infomation:
I wiped all ATI drivers and clean installed the new 355.60 drivers
I verified all monitors function using DVI and HDMI and all fail on all the DP ports.
DP --> HDMI cable used: Cable Matters Gold Plated DisplayPort to HDTV Cable 10 Feet (look on Amazon)
