Windows 10: Updated to windows 10, screen now very dim and I can't adjust it

Anyone tried this?

"I found a way to install latest Intel HD Graphics. Just download driver from Intel's website and install that on your PC. After that open RegEdit and search "FeatureTestControl" and change value to 0xF048. Then restart your PC and brightness controls works fine."

 

I encountered this problem on my AMD Mobility Radeon HD 5000 series graphics card. Go to 'Device Manager' 'Display Adaptors' and uninstall the Display Adaptor. After uninstallation, Win10 will automatically re-install the correct driver.

It was a worrying thought to uninstall a key component, but my colleague said that there is always a basic generic driver available that will handle basic screen tasks. Luckily for me, he was right!

 

I should also add that before this fix the adaptive brightness was on the correct setting, but I still had a dim screen.

 

I found the solution on this Blog. -> http://blog.teksoporte.es/2015/11/le...reglar-el.html

The blog is in spanish but it's easy to follow up. Basicaly you just have to edit a reg key and restart the pc.

 

Windows 10 240 and 586 both have a grayscale calibration bug. This could be part of your problem.
For me I had to override the color and greyscale with NVidia's control panel.
No idea with AMD or Intel but you should have a similar setup.

 

Thank you, IvanDavid1! I've been struggling with this issue since upgrading my Dell Studio 1737 laptop in August. It was so bad that I avoided this laptop and turned to my old Win XP desktop for word processing and used my little Win 10 ASUS Transformer and Windows smartphone for everything else. Your solution worked for me. I can see again. You've given me back my laptop.

 

Thanks for the solution IanDavid1, however, your solution worked partially for me. I chose the Microsoft Basic adapter, and the system demanded a restart. When I restarted it, pretty much everything on the screen was disturbed, and was scattered here & there. I took a gut feeling and selected the HD driver again in the list from where we had selected the Basic driver (from the path given in your thread). I selected the HD driver again and Voila! ... The display was bright again, all the screen items were properly organized as they were before and above all, it is accepting the brightness controls now, I can select the brightness adjustments as I wish. Hope this will help others too.

 

Thank you! Oh, thank you, oh so much! I have been living with a dim screen for the past 2 months and nothing helped, nothing! I am writing this from my fixed computer thanks to your advice!!!

 

I have a Lenovo P400 Touch. The brightness of the display could not be changed. I read on the internet that to correct this. Turn the power on when the LEONOV comes on the display press the bright + key and the display will get brighter. once it boots it will not adjust again until the power is turned off and on again. Hope this helps you.

 

Since installing Windows 10, I am unable to turn off or hibernate my laptop without having a dim screen upon restart. Once I revert to basic graphics, I get a bright screen BUT basic does not allow for a second screen. If I revert from the Intel HD Graphics 4000 to the basic, I go from dim screen to bright screen. If I re-install the Intel HD 4000 drivers while the computer is on, I keep the bright screen and can run a second screen. Once turned off, on every re-start, I must go through the same process - back to basic, re-install HD 400 drivers, re-start and then two bright functional screens again. It is time consuming and a major hassle. Any ideas? I need the second screen to operate. Using only the laptop in basic graphics mode is not an option.

Thanks,

 

Thank you so much - this got me out of trouble with a Sony Vaio laptop. As someone else put - after changing the adaptor to Microsoft Basic, the screen went blank. I rebooted the laptop and it's now as "bright as a button"

I have done the same thing with the same results. However, after turning off my laptop and then restarting with the Intel HD 4000 graphics card, I get a dim screen again. So I roll back the drivers to Basic in order to get a bright screen again. Once bright, I re-install the Intel HD graphics 4000 drivers so I can run dual monitors (not possible if running the Basic graphics drivers). The time waste each day is tiring. Any ideas? Running dual screens is necessary for my work.

 

the solution ivandavid1 proposed worked for me. I have a Lenovo Ideapad Z400 and had tried just about everything to solve the brightness problem after installing windows 10. Is there news about the update for the intel graphics 4000 driver?

 

THANKS A LOT IVAN DAVID,
I had facing this problem almost 6months and I've take my laptop to Sony service center in my country, but they over me to restore my laptop wo windows 7 but, just now I tried you solution and IT WORKS.. so thank you very much *Biggrin

 

Installed win 10 on a win 7 pro upgrade from Vista home, 4 GB HP a6600f, dual core processor (I think I miscalled it an i3 in my profile). Seemed to work fine, but overnight, lost the Display in Device Manager (showed as unknown device... colors and screen size were screwed up). Tried to re-install driver for display in Dev Mgr... could not do it, so I rebooted and device driver from win 7 was OK, and everything looks good. I may have let it go to sleep. I will see if there are any other problems. some problems with network settings for lan systems, but I figured it out on the Dell system.

Ooops, I just let the a6600f system go to sleep, and the display problem re-appeared. Looks like I need to try a new graphics driver. I will post more info after testing a new driver.
