[Rouis]

Hi my computer has a problem with the video resolution the monitor optimal mode is 3840x2160 60hz but on my computer it says 3840x2160 30hz I use the DisplayPort cable to the computer I plugged in the HDMI Cable to the other computer, and it shows 3840x2160 60hz how is the possible? Can you tell me any suggestions or ideas to fix this?

Hi @Rouis 

Depends on the DisplayPort version of your computer.

DisplayPort™ (delock.com)

[Rouis]

The monitor options shows DisplayPort 1.1 and 1.2 i clicked either of those settings but it doesn't let me save it

but you are sure that your computer's DisplayPort port is 1.2 or higher,

I don't know but how can I check it in my computer

If it is an HP model indicate your model and I look for it, if it is of another manufacturer, you must make the consultation with them.
