Windows 7. Whenever I'm looking at a dark picture, or something I watch is dark, or I play a game and go in a dark area, the brightness drops. A lot. And I can barely see anything. Help. Why does this happen.
http://www.howtogeek.com/107173/disable-windows-8s-adaptive-brightness-to-fix-dark-screen-problems/ Not sure if Windows 7 has that feature, but I know that some screens have it built-in. A friend of mine had such a screen, when we watched a movie the brightness kept jumping back and forth. It was annoying as hell, but unfortunately there was no way to turn it off.
Is it a desktop or laptop? Either way, if you can hook up a different monitor and try it with that we can determine if it's an issue with your software or hardware. It sounds like an issue with your graphics card's settings but just to be sure.
If it' s a brand new computer I' d update my screen and graphic card drivers, if it doesn' t fix it I' d check their known compatibility issues. If however your computer hasn' t always acted this way then I' d still update the drivers, it' s quick and it can' t hurt, and if it doesn' t solve it then I' d wonder what I did right before it happened for the first time that could have triggered it : if I installed programs I' d get rid of them and see what happens, if I changed settings I would change them back. If you' re not the only one to use that computer then ask its other users what they installed or changed around that time. Oh, and check what your screen says its brightness level is, both before and after that problem happens. It probably displays a number or something when you try to change it manually (pushing buttons). Check out if those numbers match your undesired brightness changes.
actually this monitor doesnt have those kinds of buttons and this computer isnt new, ive had it for quite some time, and the light dimming has always been there
Then it may have the kind of auto-set feature I mentioned earlier. Open the control panel (see the pic), there should be a panel about your screen somewhere in there, it might allow you to change some settings.
That' s why I said "somewhere in there", I didn' t expect a screen icon to pop up. There has to be a list of your peripherals in there and a way to display their own panel, trouble is I' ve never used Windows seven so I can' t tell you what to click exactly. In the older windows there also was such a list in one of the tabs of the ctr alt sup panel (press those three keys at the same time, a panel should appear, just don' t do it twice in a row it would restart your computer). If it' s not in there either all I can tell you is to open all the stuff in the control panel to see which does what, as long as you don' t change anything you can' t mess anything up, you should find the one you want eventually. One last thing, what you' re looking for is probably named after the brand and serial number of your screen, not just "screen".
