Windows 10: Changed my monitor refresh rate too high and now windows doesn't detect it

Hi,I have a Lenovo t14 gen 2 laptop with 2 external monitors. My 2nd monitor supports 3840x1440@100Hz,and I connected it via HDMI. I saw this option while trying to change the resolution and refresh rate, but once I did, my monitor stopped being detected. I tried replugging the HDMI and rebooting, but still nothing. In the duplicate/extend display for the 2nd monitor, it's disabled, and the resolution drop down is grayed out. Is there any way to reset the resolution /refresh rate?

:)

 

Refresh rate Problem

Hi Robert,

Thank you for posting your query in Microsoft Community.

Screen refresh rate is the rate at which the data displayed on screen is refreshed; it may be an image or some text document. Most of the users would like to set it to a higher rate but this also depends on the capacity of graphic
card and monitors. If the refresh rate is slow, the images on the display looks as flickering to the user eye and makes it uncomfortable to work.

Nowadays the latest monitors available in market will have minimum 60 Hz of refresh rate and it is very good option to set it to 70 Hz if you your monitor is compatible. Normally a high performance or quality monitors can reach
120 Hz of refresh rate. So I would suggest you to set your monitor refresh rate as higher as possible, below given steps describes how to access this feature on your Windows 8.1/10 PC.

• The default refresh rate setting is 60 Hertz (HZ); however, your monitor may support a higher setting. Check your manufacturer's documentation for information about the settings that your monitor supports.
• If you use a higher refresh rate, you can reduce the rate that your screen flickers; however, if you specify a refresh rate that is too high for your monitor, your screen may become unusable and your hardware may be damaged.
• Changes to the refresh rate affect all users that log on to the computer.

I would, as of now, suggest you to visit the computer manufacturer's support website and install the latest display and chipset drivers available for the latest operating system (currently it would be 8.1 in the list).

Hope this information is helpful. Please feel free to reply in case you face any other issues with Windows in future.

Hi Stephen,



Thank you for writing to Microsoft Community Forums.



I can imagine the inconvenience you are experiencing and will certainly help you in the right direction to fix the issue. However, I would appreciate if you could answer a few questions to narrow down the issue in order to provide you with better assistance.

1. What is the make and model of the computer?
2. What is the Windows 10 version and Build installed? (Type winver in Windows search/Run command) to provide the details.
   

The maximum refresh rate you can use depends on your monitor. If you have multiple monitors connected to your PC, each has its own separate refresh rate setting.



I would suggest you to try the below suggested methods and check if it helps.



Method 1

Check your Cables

Some monitors may have both HDMI and DisplayPort connections, but may be limited to a 60Hz refresh rate when connected via HDMI. In this case, you'd need to use a DisplayPort cable. Check your monitor's specifications or setup guide for more information.



If you're using HDMI, you'll want to ensure you're using a "high speed" HDMI cable and not an older "standard" HDMI cable.

In this scenario I would suggest you to replace the cable with the higher quality display and check the status of the issue.





Method 2

Update Graphics driver

Integrated graphics or older discrete graphics might not support your monitor's refresh rate. Be sure your graphics card supports the monitor's resolution and refresh rate. You need to update your Graphics drivers.

Refer the article
Update drivers in Windows 10 for the steps.



If the issue still persists, I suggest you to get in touch with the manufacturer support for the further assistance.

Monitor refresh rate

Hi Maypher

My name is Dayarys I am an independent advisor I will try to help you. Please follow the steps below :

Click on the Windows logo corner and Open Settings (gear icon).

Click on System.

Click on Display.

Click the Advanced display settings link.

Click the Display adapter properties for Display 1

Click the Monitor tab.

Under "Monitor Settings," use the drop-down menu to select the refresh rate you wish.

If you already did that like you showing, keep in mind that the refresh rates you can select will always depend on the monitor, graphics adapter, and resolution your device is using.

Your monitor show the 144hz and 60hz option but doest mean that it works at an intermediate rate.

You can try to update your graphic card by your laptop manufacturer model or change your resolution, but if you don't have the option no one configuration or software can change it. Sorry to give you bad news.

Regards Dayarys
