Windows 10: Brightness keys and Refresh Rate issues

Hi there,Currently I'm having issues with my 1 year old laptop, Inspiron15 3000. The brightness keys for the display are not responding any more and there is no other way for me to adjust the brightness. I also have an issue where all of a sudden the display/screen is choppy. This is most obvious when i play a video on youtube or something similar. Which when set to 720p still looks as bad as the lowest setting which it normally didn't do. Finally my laptop has really loud fans, which has been an issue since i got it, this only happens occasionally for short periods of time however.I've tried

:)

 

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.

Laptop brightness automatically decreases to zero but if I press refresh, backspace, enter, shift or spacebar keys it stops decreasing

I have turned off automatic display brightness and I don't think it is a display hardware issue as when I started the BIOS i didn't have any changes in brightness. I got an old Lenovo Ideapad Yoga 13 windows 8 i5-3337U and 4gb ram working after maybe a year of non-usage. The battery is fine it works after unplugging the charger also. Now that those details are out of the way here is the problem.

Now the problem is that as soon as I start the laptop the brightness just decreases in steps all the way to zero. If i try to increase the brightness by pressing the button it decreases again at the same rate so I have to hold the brightness up button for it to be maximum then if I press backspace, refresh, enter or spacebar keys it stops decreasing and everything is normal. After that if i press any of the number keys or brightness decrease key (f11) it again starts to decrease. Please suggest a solution I'm at the end of my wits here.
