Connecting laptop to 144 hz monitor(Acer GN246HL)

[bedcuzmed]

so this might seem dumb, but I tried connecting my new Dell Inspiron 7567 to a 144hz monitor(with HDMI 2.0 cable), but it would not work. I checked everywhere in the Nvidia settings to see what was wrong, but all I could see was a mx refresh rate of 75 hertz on low resolutions

You'll need DVI, not HDMI. HDMI will max out at 1.4 for that monitor, and that offers not even 75hz for some resolutions.

Still won't work, the adapter is not ready for that probably. While HDMI 1.4 has more bandwidth than dual-link DVI, 60+Hz is not part of the HDMI spec. You could try using HDMI and making a custom resolution in Nvidia control panel, try to push 144Hz. You may hit 120 if you're lucky

Some monitors do not do 144 Hz over HDMI, and the GN246HL is one of them. If your computer doesn't have a native Dual-Link DVI port, there isn't much you can do.

It's just a limitation of the monitor, it doesn't have anything to do with the HDMI spec. The alleged "60 Hz limit" of HDMI that people talk about does not exist, in fact some of the standardized formats listed explicitly in the HDMI Specification itself are 120+ Hz.

then shouldn't it work with the adaptor from hdmi to dvi-d?

Refer to the guide I linked; Dual-Link DVI is required, HDMI only supports adapters to Single-Link DVI.

If you don't have a Dual-Link DVI-D port, it is the same usefulness as any other 60 Hz 1080p monitor
