ROG GL702VM Mini Display Port Not Working

I bought my laptop last 2016 and haven't tested the mini display port before until now. I already updated the bios and Graphics driver. Checked also the external monitor and its cable by connecting another laptop GL503VM and it is working. Please advise what can be the fault here? Someone said it is the motherboard hardware problem. Your opinion are very much appreciated.

Hello hpesoj15,
Sorry I'm a bit confused.
What is the exact issue? monitor not recognized? image not showing ?
Which monitor is it, please provide the brand and model?
Thank you.

The issue is when I tried to connect an External Monitor through Mini Display port it is not working. The monitor will show Cable not Connected. My laptop is ASUS ROG GL702VM. I'm sure that the monitor and its cable is working because I connected another laptop.

Hello hpesoj15,
May I have the brand an model of the "External Monitor"?
Thank you.

Hello,

I have exactly the same problem.
A ROG G702VMK-GC375T to which I connected for the first time this week an ASUS VG248E monitor.
Works very well in HDMI, but not to the max (144Hz).
Using a Mini-DP to DisplayPort cable, the monitor says "No signal on DisplayPort".
Why? And what can I do to make it work?

Thank you
