After the computer is installed in the system, the dimming adjustment will not come

Hello friends, it depends on whether your computer is a desktop or a laptop, here's how:

There are three types of tuning on the table;

The first type: LCD monitor, press auto to automatically adjust, there will be some small buttons on the display, that is, used to adjust, and some are shaped like discs.

The second type: 1. Start - Control Panel 2, click System & Security 3, click Power Options 4, drag the scroll bar to adjust the screen brightness.

The third type: right-click on the desktop - click Properties - Settings - Advanced. I'm an nvidia control panel and open with adjustments.

The notebook is adjusted as follows:

Tell you a good way to protect your eyes: Desktop->Right-click->Properties->Appearance->Advanced > Item Selection (Window), Color 1 (L) Selection (Other) Change the color tone to: 85.

Saturation: 123. Brightness:

205 > Add to custom color > Determine at the custom color selection point > OK so that all documents are no longer dazzling black on white, but very soft bean paste green, this tone is configured by ophthalmologists, and it will be very effective in relieving eye fatigue and protecting eyes for a long time. Hold down the Fn key at the same time, and then press the F5 and F6 keys, and the above flag on each represents a parameter adjustment. The icon for adjusting the brightness should be similar to the small sun, one is brightened, and the next one is dimmed.

Just try it and you'll find out. F5 should adjust the display output, if you press the screen and it doesn't show, just press it once or twice.

Dear Lenovo users, hello!

If you have installed the official power management driver or hotkey driver correctly, you can adjust the brightness of your screen by using the FN key and the brightness adjustment key. If you have Windows 7 installed, you can also move the console by pressing the Win key and X key at the same time, and you can also adjust the brightness, if you have installed the Windows 8 operating system, you can move the mouse to the lower left corner of the desktop, click the right button, and then select the mobile console to pop up the console.

The dimming of the display should have nothing to do with the system and the driver, it should be the display that is faulty.

If it still doesn't work, it is recommended that you enter the BIOS to see if your display is normal, if it is not normal, it may be that your monitor is faulty, it is recommended that you send your computer to a nearby service station for testing and repair, and the service network query link.

The brightness can be adjusted in the monitor's settings.

You can tune in the computer. Right-click on the blank space of the desktop, "Properties" - Settings - "Advanced", then you may see the control panel of the graphics card driver, which basically has adjustment functions.

It should be the software that triggered the change of the graphics card properties, not a failure, and it can be used normally.

Hello. Based on your description, we would like to make the following suggestions.

Hope it helps you and have a great day!

The description screen is broken! It won't be too expensive to buy, one or two hundred!!

I've been bothered for a long time and finally found a solution.

If you also set the display brightness reduction in your power plan, it may be that your computer's automatic light sensor needs to turn off the smart brightness control.

After the power plan you selected, click Change Plan Settings, then click Change Advanced Power Settings, select Lenovo Power Management, click to start Lenovo power management software, select the gear icon in the middle of the three small icons in the lower right corner of the pop-up interface, and then select Smart Control, remove the check mark in front of Smart Control, and OK.

Look at your power management in the bottom right corner, is it the balanced mode selected, or the power saving mode? Generally speaking, the default mode you buy a computer is Balanced mode, or Super Mode is dark.

System battery configuration issues! You can change the battery options on the control panel at will.

Dear Lenovo users, hello! You can refer to the Lenovo Technology Forum, where there is a comprehensive knowledge and analysis discussion.

Is it because the system has started the power-saving mode?。。

Or the brightness of the screen will change when the laptop is plugged in and unplugged from the power cord. I suggest the next Lenovo Energy Management to try it, there is it on the official website.

Update the graphics card driver and try it.

Dear users, it is recommended that you reinstall the graphics card driver and power management software for testing;
