XPS 15-7590, LCD flickering on lowest brightness, #2

Its fixed with lates bios update

Not for me. If it is in charging and I use the minimum brightness, the half left of the screen is always flickering like a problem of electromagnetic noise. For a pc of $2800 this is not acceptable. And with a pro support plus is still awful that after 1 day no one answers!

Assistance change me the screen, after the mobo... Problem still here. 

I'm waiting a solution but I'm very upset. 

I have just noticed the exact same issue. Laptop (XPS 15 7590 LCD touch) charging, lowest brightness, left half of screen flickers. ?!

Hi, facing the same issue.

Had you found a solution? 

Cheers 

No solution yet. 

I'm talking from about 3 weeks with Dell engineers. They try to make another change of screen of another manufacturer (actual is compal), if the problem still persist They swap my entire PC with a new one. 

They said that is a problem of OPR or something similar... 

Third repairing operation...they changed me (another time) screen with a new one, this time with a Sharp panel (before it is Compal), the problem is identical as the previous one. LCD flickers during normal operation at the minimum brightness.

No, is not a sw problem. 

I had the same issue on BIOS and Linux 

3 support interventions:
\-they change me the screen at the half of september

\-they change me the mobo at the beginning of october

\-they change me another time the screen (?!?!) at the end of october

I accept, my bad, the replacement unit that arrive at the end (29th) of november.
yesterday (5th) of november, the pc turned off suddenly during use in battery mode with 90% of battery.
I talk with support with phone, and they said that the motherboard is dead (motherboard that is one months old).

So, I am with no pc, without the possibility to recover the datas and witohout 2500€ in my pocket.
And, as you can read on reddit, probably with a new pc with the same shitty problem.

After more than 30 thousand of euros to DELL, my company will never buy anymore a dell product, at first for the poor support received (and I make pro support plus for 4 years), at second because they give me probably a product with the same defect. So, i ask for a refound. 

Wow, I have the exact same thing. i7 model with 4K touch. Doesn't happen when on batteries. Happens when I'm charging (Dell charger or USB C).

Thanks, Buddy,

It worked for me. 

it's likely related to power issue.

using intel xtu limit the power max to 50watts or lower max intel turbo frequency to 3.1ghz or below would temporarily make this flickering goes away, but you lose around 10-20% cpu max performance.

I am having the exact same issue except that I am battery power.  The Intel Graphics Control Panel solution did not work for me.  Oddly enough, my issue did not start until after the most recent January BIOS update.  Incidentally around the same time there was an update for some sort of Intel Management software, though I don't recall it having "Graphics" in the name.

I am no expert, but could there possibly be a conflict between the Intel software and the NVIDIA software since both are theoretically involved in the same area and could potentially be sending conflicting instructions to the panel?  I recall in much older computers having issues similar to this when there were redundant programs issuing conflicting instructions to hardware.
