Can't changed from 59Hz to 60Hz

[kiicki]

This is probably not a big problem, but I find it odd. The other day I noticed that my monitor was running at 59Hz, so I changed to 60Hz, applied, and pressed OK. Today I see it was still running 59Hz, so I did the same thing, and checked if it actually did save the changed. It didn't.

Symptoms

---

On a computer that is running Windows 7 and newer versions of Windows, you cannot change the Screen refresh rate for certain monitors. Specifically, this behavior occurs on monitors that report a TV-compatible timing of 59.94Hz, but not 60Hz.

 

Cause

---

Certain monitors report a TV-compatibility timing of 59.94Hz. Therefore, Windows 7 and newer versions of Windows expose two frequencies, 59Hz and 60Hz, for every resolution that is supported at that timing. The 59Hz setting makes sure that a TV-compatible timing is always available for an application such as Windows Media Center. The 60Hz setting maintains compatibility for applications that expect 60Hz.

 

In Windows 7 and newer versions of Windows, when a user selects 60Hz, the OS stores a value of 59.94Hz. However, 59Hz is shown in the Screen refresh rate in Control Panel, even though the user selected 60Hz.

No action is needed.

 

This behavior is by design for monitors and TVs that report only 59.94Hz but not 60Hz. Both 59Hz and 60Hz are translated to 59.94Hz before these values are sent to the driver. Therefore, the display is identical at 59Hz and 60Hz.

@kiicki This is the correct answer, I had the same issue with my Samsung T240HD and there's nothing you can do as this is the monitor's correct refresh rate in Windows. This "problem" is usually on monitors that have some kind of TV functionality (that Samsung T240HD can be used as a TV as well) as mentioned in the quote.

Thank you. Class response. No worries then. I was just curious, so thanks for explaining!
