Video brightness problems with mini hooked up to TV

Only thought I have is that it's some Auto setting or thing on the TV or amp that is doing it.

Hi.

I have the same issue on my mac mini late 2012.

The brightness changes randomly (and often) when wathcing movies I bought in itunes, but only in itunes.

Netflix and viaplay is fine, no problems there?

If anyone has a sollution to this problem I´ll be very grateful. Have tried to contact apple about it,

but they did not have any sollution to the problem and only asked for a logfile to continue trouble shooting?

So the issue remains a very annoying problem. This problem is not on my apple-tv watching the same movies,

so it seems that it is only related to the mac mini combined with itunes?

Any suggestions can be posted here or sent to my email: persag@hotmail.com

I have the same setup (Mac Mini 2012 & HD TV) and the same problem.

When the Mac Mini plays in 'full screen' everything goes a bit duller playing iTunes HD movies.

Things get brighter when subtitles are on and then the 'correct' brightness appears when (and only when) there is something to display.

Notice that the brightness changes whenever the mouse is moved (i.e. whenever any OS X interface element appears).

Extremely annoying. Doesn't happen with Apple TV.

Any suggestions anyone???

Hi.

Sorry, but I´ve been trying to find a solution to this problem for quite some time without success.

Have googled it many times and read about different solutions, but nothing have solved it so far.

Have hoped an update of iTunes and/or the os would solve it, but so far nothing has?

So if anyone has any suggestions, i would appreciate it:)

Hi.

It seems that I finally have found a solution to this problem. It is not perfect, but at least it stops the screen from changing the brightness randomly when watching movies from my mac mini.

The solution is to go into settings, accessability and turn on switch control. I hide the switch control as much as possible in one of the corners down to the left or right corner and makes it as small as possible. It seems it must be active on order to stop the screen from flickering, so I can live with that.

As I said, it is not perfect because a small corner of the switch control will be visible while watching movies, but it is better than the flickering.

If anyone has another or better solution to this problem I´m all ears:)

Have a flicker free afternoon all who have had this problem on mac´s or other iOS devices.

As mentioned, you guys need to go into your TV settings and make sure that any kind of dynamic contrast and backlight setting is disabled.

In addition, make sure that energy saving modes are turned off as well.

Many new TVs have modes like this (often on by default), which are meant to save enedgy and also give the (fake) effect of improving contrast on a backlit screen.

In practice, these do nothing more than severely degrade the accuracy of the overall image.

You might also do some Google searches on basic TV calibration, as absolutely no consumer TV comes out of the box with an accurate or even good picture.

All manufacturers do this on purpose in order to catch your eye in stores. It may look good to the untrained eye, but the image it gives in terms of contrast, brightness, white balance, color, etc. is not even close to what the director is seeing in the studio.
