Dell UP3214Q stuck at 30hz over DP!

[richard_jones]

Hi Alba,

Thanks for coming back to me.

I have two DisplayPort cables, a full size DP to DP, and a full size DP to miniDP. I tried both.

See the attached images that show how this is connected. This shows the method of connection and the resolution/refresh as reported by the monitor. You can also see the monitor is on DP1.2 mode.

Since my previous post I did some more testing.

I bought a Thunderbolt to DP adaptor, and it works at 4k60hz (obviously on the same monitor/computer), which is odd based of you saying the EDID is wrong.

Thanks
Richard
