My 144hz monitor stuck at 60hz? Help?

[mlcsinghuk]

My Acer Predator Z271T is an 144hz monitor but it is stuck at 60hz, I've already gone into Nvidia Control Panel and ran through the steps there but my screen either turns to no signal or just goes black. Can someone help as I would like the full potential out of my monitor?

What cable are you using to connect it to the gpu? From what I'm seeing I'd guess you are trying to use HDMI.

Yes, HDMI that came with my monitor.

For the higher refresh rates and G-Sync you need to use a Displayport cable.

Short answer: Use a DisplayPort 1.2 cable. It's better for you.

That monitor supports up to HDMI 1.4, which can handle 1080p @120 Hz as far as I know. HDMI 1.4 cannot run 1080p @ 144 Hz though, and you might even be using an older HDMI cable that only supports 1080p @ 60 Hz, like HDMI 1.3 and earlier. Basically ditch HDMI and use a DisplayPort 1.2 cable which can handle 1080p at up to 240 Hz. You can pick one up on Amazon for under 10 USD or a local tech store.

I recently got the ASUS VG8QE, and had the same problem. I have a GTX 1070 and used HDMI and it was stuck at 60hz @ 1920x1080, and wouldn't go any higher. My monitor did come with a dual-link DVI cable, and I started using it and it displays at 144hz now. If your monitor did not come with a DL-DVI cable, you might want to get one.

The monitor the OP has does not have a DVI port. So buying a Dual link DVI cable would be like lighting money on fire.

HDMI 1.3 and above can run up to 144 Hz at 1080p. However just having an HDMI 1.3+ port does not automatically mean that the monitor will support 144 Hz over HDMI, you need to have a monitor that supports the full bandwidth of HDMI 1.3, which is not guaranteed just by the fact of having an HDMI 1.3 or HDMI 1.4-compliant port, because full bandwidth support is not required for compliance. Most HDMI 1.4 monitors are limited to 165 MHz TMDS clock, the same as HDMI 1.0–1.2.
