(3-3) I checked 'Windows 11>color management>device>monitor' and found setting to be 'sRGB IEC61966-2.1'(default)

#Brightness lowers after closing window pro

They all work similar as Pro Edition 22.Q4 ) The monitor came back normal (no dimming issue)

#Brightness lowers after closing window install

(3-2) Install AMD Pro Edition 22.Q4 driver (choose driver only) (I did test several AMD graphic card drivers issued date in 2023. (3-1) Use 'Display Driver Uninstaller' (DDU / free software) to clear all nVidia and AMD graphic card drivers (under windows 11's safe mode) in my PC. (3) Temporary Solution (after many many hours to testing again and again) (2) Graphic Card: Asus AMD RX550 4G EVO (I tested Asus nVidia GT710 graphic card which did not have the dimming problem) (1) Problem: Similar monitor dimming situation Oh, the desktop icon shadows have not gone away.still there on all 5 of my machines, yes, tried registry, everything, nada. Oh yeah, the other pc's all had their video drivers updated before the window updates were applied - all AMD Radeon machines.

#Brightness lowers after closing window update

Seems the answer is to update the video drivers/software suite, at least on an AMD Radeon card.

#Brightness lowers after closing window software

Had not updated the adrenalin software in 6 months, didn't see a reason to.got me thinking.so updated to 23.9.2, reinstalled KB5031354, crossed my fingers, rebooted.and all is GOOD. Noticed another update on another PC was avail, KB5031354, let that download/install, same darn issue, monitors got very the heck was going on? Set window update not to download and install any updates.

Reinstalled the update, KB5030310, same issue. Uninstalled the MS update, KB5030310, rebooted, all was well/back to normal. All went well except on one desktop where all three attached monitors came up very, very dark - on all machines, desktop icons now had shadows. Installed latest window update on 5 machines, 3 desktops, 2 laptops. I had the same issue with brightness/darkness. The result is fantastic as it filters out the rays causing eye strain, can be peeled on or off in seconds, and reused as many times as you like (it clings to the screen and doesn't need adhesives or hardware to work.Hello and hope all is well. What I finally came up with that works great is getting a roll of tinted privacy window film from Home Depot and cut out a section to fit my exact screen dimensions. I have sensitive eyes as well and do a lot of work at night so looked into getting a screen protector like the kind used on the old CRTS, but they were too bulky, somewhat costly, and did not work well on my 17.3' laptop. This will also block some UV and blue light if you don't want to use software or use some strange Linux on which no software works at all :) Technically you can also lower the brightness by wearing sunglasses in front of the PC. Most LED monitors change the brightness via a process called Pulse-width modulation which is really bad for the eyes. One thing to note is that I don't recommend changing the brightness via monitor buttons if the monitor is LED. Iris can do this also but this is not related to the question. One plus of Iris over f.lux is that you automate the brightness reduction based on day and night just like most blue light filter programs do with the color temperature and blue light. Iris and f.lux should work fine because they change the white point of the screen which is better. This method reduces contrast quite a bit and may cause eye problems. Looking at the other answers most programs lower the brightness by placing a transparent overlay filter. This over the maximum brightness is really useful when watching movies for me Here is how brightness on 110% looks like You can go as low as 10% if you enable Extended values, but this is really dark screenĪside from going down you can also go up to 150% brightness. If you set Iris to 50% brightness the screen will look like this

Here is a normal screen with Brightness on 100% You can get the biggest possible dim range with Iris.
