How do I adjust brightness and contrast on my ASUS?

Holding Fn and pressing the up and down keys is not working. I have to squint because the computer is so bright.

If the up and down keys don't adjust the brightness on your ASUS laptop, the brightness controls are likely assigned to other keys. Do the following to find your laptop's brightness keys:

  • Look at your keyboard.
  • Find your Fn key and remember the color. Oftentimes, Fn functions are the same color as the Fn key.
  • Look at your keyboard for the icons that look like suns with arrows next to them, or differently sized suns. These are your brightness keys.
  • Hold the Fn key and press down to turn the display brightness down.

You have successfully turned your brightness down. However, if you cannot find your brightness keys, you can always use Windows to turn your display brightness down:

  • Open Control Panel.
  • Click System and Security.
  • Click Power Options.
  • Move the slider to get your screen to the desired brightness.

How do I manually change computers color temperature?

I somehow managed to change my computer's color temperature last night without knowing how I did it. I was wondering if there is a pretty universal way to do this just with the keyboard, I don't think I opened any menus up for it. My screen was pretty usual average and I somehow hit the right combination to turn it a dull orange color. I have an ASUS ROG laptop.. I have tried: I re-calibrated the color through the menus, which worked but it wasn't the way it was, it seems.. I think it was caused by: I mis-pressed a few keys on my keyboard and it changed the screen's color.

It is likely that you hit the shortcut key for ASUS Splendid Video Enhancement. Search for the program in Windows. You can uninstall it or revert it back to factory settings. This will get the tints correct for the display again.

Hi,, my brightness and volume keys aren't working on my new ASUS laptop?

I just got a new ASUS f555la ab31 laptop with Windows 10. The top row of the keyboard which includes the brightness and volume keys isn't working. When I click on them it does the task which should be done if I was holding shift while pressing the key. How do I fix this? Thanks!

Go to the ASUS website and re install the drivers for display and audio. Then restart your computer and see if the keys work properly. If they still are failing, install the drivers for ATKACPI driver and hotkey-related utilities. They are under the Utility section in the available drive list for download. If all else fails, format your computer or return it if it is under warranty.

My ASUS laptop display irritates my eyes?

I can adjust the brightness on my laptop but the screen display does not look right. Even at no brightness the whites and light colours on my screen hurt my eyes as they are too intense. I normally have to change brightness levels because looking at the same intense white begins to hurts my eyes. I suspect there is something wrong with the contrast or temperature of the colours perhaps? It is a fairly new laptop and I've always had this problem since day 1. I did not think much of it until I started using Photoshop and just couldn't make out the colours on my photos properly.. I have tried: I've tried to change the brightness settings and the contrast but they could only find brightness settings and not contrast settings. I think it was caused by: Perhaps a fault in the unit of the laptop I bought

Install the ATK package from the ASUS website for your specific model. This should help with your brightness control. Go to your Power Management settings and turn off Adaptive Display before you begin to reconfigure your brightness again. There are apps like Dimmer that help with the brightness levels and work with Windows 10.

ASUS screen Brightness Windows 8.1?

I can't adjust my laptop screen brightness either through my control panel or with Fn F3/F4 shortcut or with changing my PnP (because there isn't other).. Also I have tried installing previous driver from ASUS store and the problem still remains.

Check your Power Saving settings. Then update the drivers for the hotkeys mentioned in an above answer. Turn off Adaptive Display if it is enabled as this will also prevent the use of the keys sometimes.

Calibration not making any changes?

Hi, The white balance or contrast calibration on my monitor needs to be adjusted. Photos appear darker than they do on a number of different devices. So, I need to lighten the white balance. I went through the calibration a number of times and the adjustment/change occurs for a flash then returns to the way it was before. This is DURING me fiddling with the calibration bar, AND when I 'test it out' and press 'current' vs. 'previous' calibration before finishing up the process.

Fn key plus up or down does not work?

Hi, I just got a laptop today from my cousin and apparently the brightness is too high. I press FN plus the small sun, but the HUD doesn't come out. how do I make it work? I run k43sd

Hi, I wish the best for you, I have a problem with adjusting the setting of Intel video graphic?
