Intel HD 620 1440P & 75hz?

Aag12 — Thu, 24 Sep 2020 02:20:19 GMT

I have a dell inspiron 7378 with HD 620 and just bought a 1440p monitor that supports 75hz at that resolution.

I'm hooking up the monitor via HDMI and the refresh rate maxes out at 60hz. Is there something i need to enable to unlock the higher refresh rate? I have the latest drivers from Dell & Intel and would assume the HDMI cable provided by Dell would be rated high enough to handle the bandwith.

Any suggestion?

After seeing so many issues here, I established a rule: If the cable came with a monitor, it is trash; throw it away and purchase a quality product.

Your particular question has been asked previously. The answer has always been that 60Hz is the maximum. It makes no sense; even if the interface only supports HDMI 1.4, it can still handle 75Hz data rates for a standard 1440p monitor.

Sorry. Maybe Intel Customer Support can provide a better answer...

Hello Aag12,

Thank you for posting on the Intel* Community.

To better assist you, please provide us with the below information:

By any chance, did you test with a different type of connection (DisplayPort* to DisplayPort*)?

Provide the DXDIAG report:

Go to Start > Run or Windows Key + R.
On the Run prompt, type "dxdiag" then click OK.
On the DirectX Diagnostic Tool window, click on Save All Information.
Browse to a folder, type in a filename then click Save.

With the external display connected, provide the Intel* Graphics Command Center report:
