When laptop display turns on after being off for, I notice high brightness

[SFish3]

I bought the Xiaomi Air 13 Laptop (Windows 10 Pro) which has integrated Intel 520 graphics (and a dedicated nvidia 940mx card).

When I don't do anything on the laptop for 5 minutes, the display will turn off (this is set in the "Power Options"). Once you move your mouse (or hit a key) the display will turn back on. At that moment when the display turns on, I observe a VERY high brightness for ~50 milliseconds and after that, the display immediately adjusts to normal brightness.

If you set the display brightness to 100% everything is fine, because the graphics card - for what ever reason - sets the display brightness to 100% EVERY TIME the display is turned on (after being off). So you don't notice any difference because the transition from 100% to 100% brightness is smooth. But if your display brightness is set to (e.g.) 70%, you will observe a 100% brightness for 50 milliseconds, followed by a 70% brightness. This looks ugly and looks like a "lightning" to me. Apparently the graphics card will set the brightness no matter what to 100% when the display is turned on from a display-off state (even from sleep state), but it would make more sense to first set the brightness to 0%, then retrieve the brightness information, and set it accordingly....

I am looking for a way to fix this, does anyone know how? I disabled adaptive brightness on Windows 10, but it all doesn't help. Any help is appreciated! Thanks.

p.s.

http://en.miui.com/thread-318018-1-1.html Here are the recommended drivers for the laptop. I used the following recommended Intel Driver Version 15.40.23.64.4444 (even an update to 21.20.16.4534 didn't help).

Hi,

I do not think this issue is related to drivers since you are moving brightness to 100% and the problem is not present. I would say this is the way the screen adjust the brightness of your screen.I recommend loading the latest graphics drivers and you will confirm if this was driver or hardware issue.https://downloadcenter.intel.com/download/26464/Intel-Graphics-Beta-Driver-15-45 https://downloadcenter.intel.com/download/26464/Intel-Graphics-Beta-Driver-15-45-Allan.

Were you able to test driver version 4552?

No when I open the .exe it says that this driver cannot be installed on this laptop. Right now I think it's not graphics driver related, must be something deeper... like the display drivers circuit... Thanks anyways.
