Monitor screen randomly dims when in Windows Media Player

[Daniel543M]

Hey guys,
So today I open up WMP to watch a movie and for some reason, during the movie, when I'm in fullscreen mode the screen dims.

The actual movie gets darker and if I exit fullscreen mode, the actual desktop screen is dark and it brightens back to normal.

This will happen randomly when in fullscreen mode and it's not constant.

Today is the first time this has ever happened and I have no idea why. I was hoping someone from here could help me out

NOTE; I am using a PC not a laptop. Windows 7.

Thanks!

Please check your video card drivers for a video option called dynamic contrast enhancement(for Nvidia it is under Adjust video color settings -> advanced. I am not at an ATI system right now). This should ONLY effect the video playback and nothing else.

Many monitors have this kind of feature to over rate the contrast ratio(this works by making the screen or even backlighting dim with dark scenes and go brighter on lighter scenes. I personally can not stand this "feature"). You may see many 20 million to one ratios, these are ALL dynamic because consumer level screens tend to have trouble getting upto 1000-1500 to one(some new VA panels can get a static of 3000 to one.)

If you want to test this, try to make a image BLACK and large as you can in something like paint and look at the start bar as you minimize and maximize this window. If it gets darker and lighter, chances are you have dynamic contrast.

Most screens can turn this off.

Thank you! I had a look at my monitor menu (there are buttons on the actual monitor) and I found one called "MagicBright" so I went into that and saw that all of a sudden "Dynamic Contrast" was now selected. So I just changed that to a different one and it works fine now.

Thanks again for the quick answer

And here I was making you a demo image

Dynamic contrast simulation

If you do not like things overly bright, try out the text or internet preset if you have it. I use those for everything.

This fixed it! All along I thought windows was the culprit but it was my monitor!! Now everything works perfectly. I've been fighting with that for months!! I found out that my monitor has it set under energy savings, and it is actually dimming the backlight! Like omg. LOL. No more dimming on videos!!

I know it's been a long time now but I'd like to thank you for this. I solved my problem of my screen dimming the image when it was dark by going into my NVIDIA settings like you described and it works now!

Thank you!

Glad it helped.
