Dear Sir,
When we set BIOS display device as DP. And we used SN75DP120 with DP connector but we did not connect DP monitor.
This situation let system hang when enter Win 7. But if we set BIOS display device as HDMI.
And we used SN75DP120 with HDMI connector but we did not connect HDMI monitor. The system is normal.
Is system hang issue cause by DP link training failed, or there are another factor would let system hang.
Thanks
James
