144hz on hdmi

I recently bought a dell d2719hgf monitor which can go to 144hz but when I try to game it keeps turning on and off but when I exit it returns to normal. My question is is it because I’m using the included hdmi cable or do I have to use a DisplayPort cable?

It's a known HDMI limitation.

Use DP cables.

144hz and hdmi is supported

That does not mean the hdmi port on that monitor will support it.

Since dell seems to be keeping it a secret what their hdmi monitor port will support you will need to give them a call and ask.

Yes, HDMI the spec allows it.

But rarely implemented. So rare that for now I just go with displayport when the client wants to go outside of the usual 50/60 Hz.

This would have been easier if dell had shown the spec on their hdmi port.
