144Hz Monitor Not Running At 144Hz

[chasmo123]

I've got a 1440p monitor that runs at 144Hz. I know that it works as there's no problem when using the DisplayPort on my desktop computer. However, I recently got the new Razer Blade which only has an HDMI port on it.

When I use the HDMI connection, the monitor refuses to rise above 60Hz. It goes to the correct resolution, just not the correct refresh rate. I thought the laptop might have an older HDMI port, though according to Amazon, it's an HDMI 2.0 port, which should support 4K at 60Hz, so there should be no trouble.

I'm unsure what the best way to go about solving this problem. I have used the built-in Intel Graphics Settings, I've used the NVIDIA Control Panel, and the Windows 10 Display Settings to try to change the refresh rate over 60Hz, to no avail.

Are there more solutions to the problem, or did I just miss something?

Any help is greatly appreciated!

Both the computer and display must support the required HDMI version, just having a laptop that supports HDMI 2.0 does not mean every display you connect it to will now be capable of accepting HDMI 2.0 speeds. Likely the monitor only supports HDMI 1.4, though knowing the display model would help.

(And, before anyone says so, HDMI is not inherently limited to 60 Hz, that is a myth.)

Right you are. Interesting that Dell would put a port on their monitor that is unable to support the correct refresh rate, but here we are. The port is HDMI 1.4.

Another question: I'm also unable to run at a lower resolution but a higher refreshrate (i.e. 1080p@144Hz). Is this also being limited by the older HDMI? Or is there something I could do to fix it?

Firstly, don't run an LCD monitor at anything other than it's actual resolution. Doesn't look ideal.
I'm pretty sure you can get an HDMI-DP cable/adapter that can do what you want.

If you're talking about the Dell S2716DG/S2417DG (G-Sync monitors), unfortunately Dell has no choice, because they have no say in the hardware design of the monitor's controlling electronics, they simply put in a proprietary G-Sync control chip designed and manufactured by NVIDIA and have no control over what capabilities it has. The port selection is the same on all G-Sync monitors, one DP 1.2 port (and for Gen2 G-Sync modules, one HDMI 1.4 port). We will have to wait for NVIDIA to release a new G-Sync module with HDMI 2.0 support (which was announced some time ago, coming soon™). This is one of the unfortunate limitations of G-Sync in comparison with FreeSync.

Display format options that are available depend on what the display reports, the display sends over a list of supported formats to the operating system upon connection, and these are the options that appear in Windows. They don't list every conceivable possibility (which would be quite a lot), though sometimes they do leave out some rather obvious ones. If you want to run 1080p 144 Hz you can try setting it as a custom resolution, which will force that option to appear as a selectable option in Windows. You can set custom resolutions in the NVIDIA control panel under "Change Resolution -> Customize". Enter 1080p 144 Hz and set the timing standard to CVT Reduced Blank. Or you can download the ToastyX Custom Resolution Utility and use that.

Noted.

I think I'm just going to go with a USB-C to DP and not mess around with the HDMI at all.

Thank you for the help.
