New 144hz monitor causing PC to not boot

[Ermandfa]

Hello,

I just bought the Viewsonix XG2401 144hz monitor. I have it connected to my r9 280 via mini displayport. When the monitor is connected it appears that the computer cannot boot properly. The fans will start for ~2 seconds and then turn off and back on.

If i disconnect the monitor the PC boots with no issues. I can then plug the monitor back in and it works fine until I turn the pc off again.

Has anyone experienced this before?

Mini DP is touchy, use full sized display port or DVI-D.

Unfortunately the r9 280 only has mini displayport or DVI-I. I don't think I have any other option. I don't believe DVI-I works with 144hz does it?

The DVI-D connector goes into the DVI-I connector just fine from what I can remember.
They're backwards compatible so long as they're both dual link or single link.

So I went to the store and bought two new cables. One a HDMI 2.0 and the other a new display port to mini display port. HDMI 2.0 was capped out at 120hz. I tried the new display port to mini display port and everything is working fine now. I guess I got a bad cord which was causing a short circuit or something.

Ah, I see.
Glad to see you sorted it out.
