Well the title says it all... I updated Windows and brightness is now locked on minimum. Even if I press F12 or go into the settings, the brightness bar will fill but the screen won't show any changes at all. Sorry if I mispelled anything but I can barely see on this screen due to this issue. Can someone please enlighten me? Literally.

My screen brightness using FN+F11/F12 and also in the advanced power settings slider won't adjust the screen to anything other than brightness and minimum or brightness to 100% when I move the slider.  It shows the percentage moving up and down, but the screen stays 100% until I'm on the lowest setting,  then it goes right to minimum.  I received a bunch of Lenovo updates on the first Wednesday of this month and I've had several issues since then, I tried reverting back to previous drivers, but it made no difference, so I'm back on the latest drivers.

Hello there, I need help please! I can't fix the screen brightness. It appears to be stuck on full brightness which draws my battery life quickly and hurts my eyes during nights. The brightness button in the action center is missing, there is no brightness slide bar in the display setting nor in control panel, and brightness fn buttons in the keyboard are not working as well. When I click on the battery icon, there is a brightness button next to the battery saver button but also not working (not even clickable).I searched online and I tried:- updating/reinstalling/rolling back display drivers- resetting pc (reinstalling windows)- many other little repairs College is starting soon and I really need my battery life and I will be studying on my laptop in late hours so this brightness issue is a big trouble for me

Does anyone have any idea on how to correct a problem I am having with my deaCentre A520? All of the sudden I can no longer use the touch buttons on the bottom of the screen. They light up when touched - HDMI, brightness, volume, etc - but they no longer work. I have been running Windows 10 for sometime now - I doubt it is a software issue with MS. Any idea on how to correct this issue? I can use the touch screen just fine - just not the control buttons on the bottom of the screen. Thanks.

Thank you forum! Much gratitude here for your selfless service!!

I am not very tech savvy but I am usually able to solve my own problems. My cat jumped on my keyboard, my display went dim and I could not adjust it ! I am able to move the brightness bar up and down but nothing happens. First, I tried a system restore but that did not work. I went back about a month which was the earliest restore point I had. Then I went to device driver and looked to see if my driver was functioning properly. I was told it was updated and functioning properly. I tried clicking on the windows generic monitor driver also as advised which did nothing. I went to the device driver on the pc and updated from that which also did not work. I am using windows 10.

Hello! When I connect my Yoga 900 laptop to my Samsung external monitor using a USB-C/HDMI adapter, the laptop screen flashes black and the external screen does nothing. Between the flashes I can see my desktop background goes blue and every program/file that is open begins popping up and closing on repeat. Nothing ever shows on the external monitor. The only fix is to unplug the two, but if I let the laptop flash for more than about a minute it eventually goes black. When this happens, unplugging it from the monitor does nothing and it has to be manually restarted using the side button. As noted in other forum solutions, I manually updated all video and chip drivers.I have tested the monitor's HDMI port, the Yoga 900's USB-C port, and the HDMI cable itself. I have also tried a different brand of USB-C adapter. Pressing Windows + P doesn't seem to do much, as I can see the menu between the flashes and click "expand" but nothing happens. Any idea what else I can do? Thank you.

Hey guys, so I've been having some problems since I updated to Windows 8.1. My screen is stuck on dim. It's not dim enough to be unusable, but it's dim enough that I wish I could turn the brightness up. If I use the hardkeys on my keyboard to turn it up or down, the bar will go up and down, but the brightness won't change. Same goes for using the settings charm brightness bar and adjusting via control panel. I've tried updating my display and video drivers, and messing around with the battery "power plan" settings, but after all that it still won't change. Any suggestions?

Instead of allowing me to set the slider to any position I want I'm stuck with only 3 steps from which to choose from.
The last one is way to bright and my eyes keep tearing up from having to deal with this insane amount of white, especially on white backgrounds.
The other two are very, very dark.

Also I can't seem to set the brightness by using the FN keys on my keyboard. They simply produce no result at all.

Help appreciated, I can't work like this.

Hi there. I've installed a clean version of Windows 10 Home 64 bit, and, noticed that, with the basic Microsoft display adapter driver, I would be able to adjust screen brightness and would get maximum resolution as well. How ever, even though I disabled automatic driver updating in Windows before I first connected my laptop to the internet, it still proceeded to download a driver that it got via Windows update which ruins the adjusting of brightness. I tried to install the 64-bit Windows 8 driver that is available at support.lenovo.com but that one has the same problem, I can't adjust screen brightness when using it. Neither did the latest Windows 10 Radeon HD 6xxxM driver by AMD off of their website help at all. Everything else works perfectly fine in terms of Windows 10 except for adjusting of brightness, and, I am unable to stop Windows from constantly updating the graphics card driver via Windows Update despite the setting found in System Properties. As such, the laptop is, largely useless, and, has wasted loads of my time. It's a shame really, as, I invested loads into this laptop, and, though it's perfectly capable of running Windows 10, the fact that I can't adjust screen brightness wrecks everything. I have even installed the Energy Management driver, but, that doesn't help anything either. Could someone, please, advise me of some way through which I could make Windows simply STAY at the Basic Microsoft Display Adapter driver, or, w...

A:Windows 7 Enterprise x64bit [ Cant adjust screen brightness ]

What driver pack? Win7 is a driver-complete OS after you enable Automatically deliver drivers via Windows Update (Step 3) then run all rounds of Impotant and Optional Windows Updates until no more are offered when doing a Check for Updates after reboot.

Any drivers then missing should be imported from the HP Support Downloads webpage for your exact model.

If you have an HP then don't reimport any of the HP bloatware but sometimes a piece of software is required to make the hotkeys function correctly. You'll need to study the software posted for your model to see which is required. If you tell us the exact model and link us to the webpage we can often spot it for you if you need help.

Hopefully you followed the other steps for a perfect Clean Reinstall - Factory OEM Windows 7 because you will get and keep a perfect install to the exact extent you stick with the tools and methods given.

If you forced a bunch of old drivers into an OS which provides its own drivers then you will have problems.

I've noticed, today, that I'm suddenly unable to adjust my screen brightness. I have read half a dozen threads reporting the same problem; I tried all the solutions therein (from updating the driver and reverting to the most basic one to manually changing power configurations) and nothing worked. Unlike the vast majority of users who had this problem, this hasn't happened following an update to windows 8.1 (which I did several months ago -- and the adjust was working fine after that).

This might give you a hint:

* As I try to adjust it using the fn key (as I had always done previously), brightness goes up or down just one level -- and that just 'cosmetically', as in fact nothing changes. The indicator gets stuck approximately in the middle of the bar, unable to reach the extremes.

* There is more: on power management, I chose the lowest possible level of brightness when working on battery, just to see what would happen. I then disconnected my laptop from main power, and... the brightness indicator did go down to the lowest level, YET brightness remained unaltered in fact.

Anyone, please??

Hey all,  I recently bought a Lenovo Yoga 720 15-inch 4k and love it! Unfortunately, it was stolen in Mexico and I had to buy a new one upon returning to the States.  One of the first things I changed when I got my first 720 was the screen brightness. I switched off the "Adaptive Brightness" setting in System > Display settings and that seemed to make my screen nice and bright white.  Now, on my second computer, even at 100% brightness and with the Adaptive Brightness switched off, the screen looks much dimmer and not as crisp white.  Any thoughts on what might be going on? Thanks! Dave

For months now my laptop has been logging me out after I just logged in to use it. Once I log back in after this I find that I can't adjust my brightness in any way. Whether it be through the device settings or by using the brightness F keys. There is also a strange square that shows up that often changes colors and location on my screen (2nd image). When i go into the device manager this is what I see (an indicator that something is wrong with the display adapters): I have tried uninstalling the Intel(R) HD Graphics Family and re-installing it and that fixes the problem temporarily, but when I shut off my computer and go to use it the next time the same problem persists. I've gone into the Lenovo Vantage and run Health and Support tests, but it doesn't detect anything. I've downloaded updates recommended for my system and nothing seems to work. This problem is really starting to irritate me and I would like to try and fix it before investing in a new laptop. This laptop is only 4 or 5 years old. I would greatly appreciate any other tips or advice!

Hi! I have an ASUS VS238 monitor. I'm trying to change the brightness settings---way to bright.

After a few seconds the box disappears. I've tried using the cursor, but as soon as it tries to enter the brightness box it disappears. I've tried the menu button, and the up down buttons don't work, but if I push the menu button again, it drops down to standard. I push the button again, and I get a box asking yes or no.

Hi,

I recently purchased a Lenovo Yoga 900 to replace an older Lenovo Thinkpad. I use two laptops with the same peripherals, so I run an external monitor (Dell Ultrasharp 29" monitor), a keyboard, and a mouse into a Display Link Docking Station. I then use a IOGear switch to toggle between the two laptops. The new Lenovo Yoga laptop picks up the keyboard and mouse, but does not identify the external monitor. Below are details on the new laptop.

? 6th Generation Intel Core i7-6500U Processor (2.50GHz 1600MHz 4MB)
? Windows 10 Home 64
? Intel® HD Graphics 520 (graphics card)
My other laptop is an HP ProBook running Windows 7 Professional. All of the peripherals work fine using the docking station and switch (as did the old Lenovo Thinkpad). The only exception is that in my previous configuration, the monitor would periodically not connect with the new laptop when I used the switch, and I would need to restart in order for the monitor to work with the latpop I had selected on the switch. The mouse and keyboard did not have this problem.

Thanks for your suggestions.

HiI updated Windows 10, and now my external screen only displays 1280x720 pixels instead of 1920x1200. I cannot add this as a custom resolution in the intel driver, because there is "not enough bandwidth". This is the case if I connect it with the HDMI output on the laptop as well as the HDMI output on the OneLink Dock.I installed all the newest graphics drivers, didn't help. Any other solutions?

RELEVANCY SCORE 77.2

I'm getting a Lenovo 4K laptop soon but in the interim I'm trying to hook up my Lenovo Yoga 920 (which is a 1080p laptop) to a 4K monitor. Do I basically just use the exact same method I used to connect my laptop to a 2K monitor.... so I simply need to use the exact same (USB-C to HDMI) adapter in order to connect it to the 4K monitor and then my moitor will display the 4K res? Thanks in advance for any input!
