Hello, I tried a CAC-1080 I received today, and it would not display any picture. I have a few HDMI 2.0 cables, so I know that’s not the issue coming out of the adapter. I am wondering if CAC-1080 (that mentions DisplayPort 1.4) isn’t backwards compatible with DisplayPort 1.2 as my PC is? Or are there Windows 7 drivers I might need to install for the adapter or should it just be plug and play (lists Windows 10 on the website). I’ve tried different graphics driver versions, all the different ports on the TV, switching HDMI 1.4>2.0 on and off, etc, etc. and cannot get the option for 60Hz.
Some background on the situation and the reason I am needing to use an adapter in the first place is the PC only has HDMI 1.4 port, which can only support 3840×2160@30Hz.. in order to achieve 60Hz I need to find a way to use the DisplayPort output.
My setup is as follows:
Intel i5-7400 running Windows 7 Ultimate with Intel HD630 Graphics : Supports DP @ max 4096×2304@60Hz
Monitor/TV Sceptre/Komodo KU-555 : Supports 3840×2160@60Hz with HDMI 2.0 inputs
Please let me know if you need any further info. Thank you
