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.

 

Old CRT Refresh Rate Issues


Hello everyone, just built a new PC after about 7 years and I'm coming from XP64. Although I plan on purchasing a new monitor soon I am still using my old ViewSonic G90f CRT. With XP I used ReForce to use refresh rates of 120hz in 640x480/800x600 and 100hz in 1024x768/1152x864. In Windows 10 I can only select between 75 and 85hz, when I use nvidia control panel and attempt to increase refresh it claims frequency is over range. Odd that it worked fine in XP for over 7 years. I do not have any drivers and I assume there probably aren't any available for 10. Is there any fix for this or am I stuck with 85hz until I update monitors? Thanks.

Old CRT Refresh Rate Issues


This may be a Windows 10 issue in that it will not work with all the refresh rates despite the hardware having the capability to operate that way. I think you may find it difficult to get a workaround, so I would get that new monitor sooner rather than later (and be amazed at the difference !).
Failing this, there is also a utility called CRU (Custom Resolution Utility) that may help. You may have to play with different resolutions. But first make sure your drivers are up to date.
