Windows 10: New computer- monitor seems darker and can't adjust

I have a Samsung SyncMaster SA550 that when connected to new computer does not seem to be very bright. I've looked in the Action center and there is no option to adjust brightness. I've tried the adjustments on the monitor itself, but still remains dark. Any help?

darker monitor

After turning of the computer and installing a lot of Windows 10 update, my monitor became much darker. It started with normal colour and after a few minutes it became darker. Tried to restart several times and also tried with another monitor and the same
with that, so the problem came with the update and are obviously in the computer software.

Hi William,

• Press Windows key; then type cleartype,
  and select Adjust ClearType text.
• Follow the onscreen instruction to on how to do it.

Screen gets darker shortly after startup

When my computer starts up after being shut down or restarted, shortly after the login screen appears the screen will suddenly get darker. I have tried the following to fix it already without success:

• I have updated my video card drivers.
• I have updated the monitor drivers and the software for my monitor.
• Through my monitor's software, I have turned off any automatic brightness adjusting features. (I've also done this through the options on the monitor itself.)
• I have turned off adaptive brightness for Windows.

This has been going on for many months, maybe even a year. Any other suggestions would be appreciated. I am getting into a field where I will need to do color-sensitive work on this computer, so this needs to be fixed. Let me know any information you need
about the computer and monitor and I'll provide it.
