These settings allow your TV to automatically adjust its brightness depending on the lighting conditions of your room.īut sometimes, your HDMI cable might be the culprit.
Or, the Power Saving settings on your console may also be causing your screen to go dark when set to Low or High.Īdditionally, many TVs today come with Eco mode, also known as Automatic Brightness Control. Most of the time, it has to do with the picture and brightness settings on your console or TV.įor example, whenever the Picture mode on your console is set to Custom or Cinema, it will lower your screen’s brightness. PS4 users have been long complaining about their brightness getting too low or their screen getting too dark while watching something.
There is something wrong with your HDMI cable. The Automatic Brightness Control on your TV is enabled. The Power Saving mode is set to Low or High. The Picture mode is set to Custom or Cinema. There are many reasons why your PS4 brightness might be low: So if you have ever faced the same issue, let’s find out why it happens and what you can do to stop it. I will test this and hopefully report my findings in a couple of weeks.Many PS4 users complain about their screen getting too dark when they are playing a game or watching a movie. If I'm right then the problem can be mitigated by slightly working the jack in place, or by rotating it to a different position. Combined with some wear in the contacts this causes brief external power disconnections. But my guess is that the heat causes material expansion in the socket. I don't know if it warms up because of the current drawn by the GPU or just because the power socket is very close to the GPU fan exhaust. I have noticed during my unplugging experiments that the AC jack was very warm, almost too warm to touch. My belief is that this problem is mechanical. If I unplug my AC adapter from the laptop during the same games the dimming and slow-down are identical to when I experience them spontaneously. I did confirm that these effects are caused by the laptop switching to the battery mode. 
The problem gets worse with time, in that the frame rate drops happen more often than half a year before. Then it repeats, sometimes more often, sometimes less. The screen dims and frame rate drops drastically for a second while playing GPU-demanding games.
Sorry for resurrecting an old thread, but I'm having exactly the same problem for the last half a year.
