Display Brightness

When gaming on battery power, display brightness automatically decreases to the minimum value in Windows. High performance power profile, all screen dimming options disabled, already tried alternative display drivers and a full system restore.

RE: Display Brightness

Hello,

could you please tell us what kind of Dell Laptop and operating system you are using?

Has your system got function keys on the keyboard to increase or dim the brightness?

Regards,

Florian

RE: Display Brightness

The service tag is [edit: removed by admin]

It is Alienware 13 R2 i7-6500, 16GB RAM, 512 SSD, VIDIA GEFORCE GTX960M 2GB, WIN10

I just bought it on 18 December

The brightness changes automatically when I am playing games without charging. The problem exists when I enter the game.

RE: Display Brightness

I have tried it already. But when I play games, I am using the NVIDIA Geforce graphic card. These links are not helpful at all.

RE: Display Brightness

Independent on what graphic card is used, still you've tried the suggested steps, right?

Does this video describe the problem you are experiencing?:

The brightness in this video changes at minute 2:49.

RE: Display Brightness

I think yes. The brightness always becomes 0% and it is very annoying

RE: Display Brightness

I think the setting works. Not very sure. By the way, Thank you very much.

I want to ask is Dell Power Companion PW7015L - external battery pack - Lithium-Ion - 18000 mAh compatible with my laptop?

RE: Display Brightness

Hello,

please let me know, if the setting works on long term.

The Power Companion is not supported for your device.

Kind regards,

Florian
