Laptops General - Read Only

I received my XPS 15 recently and have noticed that the display flickers slightly when set to 0% brightness. No flicker is visible at higher brightness values or while gaming (unless my eyes are deceiving me).

I am wondering if I have a defective unit or if this is just a driver/settings issue.

Anyone else experiencing this issue? or have a solution?

Yup. Same issue here with my 9550. No solution yet.

Do you also hear a noise/static type sound coming from under the laptop when its quite enough to hear?

I got my xps 15 yesterday and noticed the same issue as you described. Mine is a nontouch, 1080 HD, 256GB, 8GM, i7 laptop...

Very annoying issue, I saw a post with the same issue, the laptop was replaced with a new screen later, but it didn't solve it...

Thinking about returning it....

I've sent mine back for a replacement, which hasn't arrived yet. Fingers crossed that it doesn't have the same issue, although it's likely that it will.

I just got mine a few days ago and I am also noticing the same issue. I believe it has to do with PWM, see:

and

Just another poor quality choice by Dell for this laptop (display response times are bad also).

According to notebookcheck, keeping it at >10% should reduce the flicker so that it is not detectable.

I've also have other small problems and now this, I'll probably just return mine.

I have the same, can also slightly notice it one step up from minimum brightness.....

Have the same problem with mine on all levels of brightness, for an £1800 laptop these things are garbage, I have so many issues with mine. Should have bought the Macbook instead, at least they're reliable

But I see that have just released a BIOS update to stop this. I have to say I really enjoy this laptop even with the issues I've had, Dell has been very willing to fix them and help.

It occurs on my XPS 15 9550 with touch display even with the latest drivers on all levels of brightness.

The issue is reduced with older drivers for the Intel HD Graphics 530 graphics card, however, flickering still also occurs in BIOS.

This seems to be a weird mixture of drivers and HW issues.

The latest A10 BIOS makes this issue even worse unfortunately, I had to roll mine back to the previous A06 version to be able to use the laptop at all. If its set to 52% brightness it occurs about half as regularly as on any other setting. Oddly I havent noticed it at all when booting in Linux and the fan issues are greatly reduced too, this could be a combination of things by the look of it.

OK, BIOS A10 is definitely the issue here. Just a quick note as I've seen a few people do it, DONT click on the updates message you get after rolling back to BIOS A06, one of the updates will reinstall A10 and you'll be back to square one again with flickering issues. 

Update for the video driver seems OK.

Have run A06 for over a week now with the screen permanently on, no flickering issues at all :)
