BIOS UPDATE A10/ A13/ A16 XPS 15 9550 4K SCREEN TERRIBLE FLICKER

HI,

I have an XPS 15 9550 laptop with 4K screen. I installed the recently released BIOS update which is supposed to address the flickering screen issue. Previously I only ever experienced some minor intermittent flicker at brightness level 0 but after the update, flickering was occurring quite frequently - I checked this upto brightness level 50% and it occurs at all the way up.

It appears the update has made things much much worse Luckily I managed to roll back to A06 which must be the previous release as its the only one on the downloads page.

Anyone else find the update made things much worse?

Be good to know what Dell is doing to sort this out (again).

It has happened to my XPS 15 9550 4K as well after the bios update. I cannot work because of this terrible screen flickering. How could you roll back to previous version? Did you call the customer support? Thanks.

i thought i was on BIOS A09 before the update but perhaps not. The previous version to download is A06.

I had the same issue, it was infuriating. After hours of playing with settings and trying to update other drivers I had to roll back the BIOS version too. Now I have the slightly lesser annoyance of the Dell update service telling me there is 1 new update available each time I boot up.

Is there any info from Dell about this?

yep its a very amateurish BIOS release, this is the least of some peoples troubles on the 9550 machines however, others are experiences total system problems thanks to Bitlocker/ TPM issues.

I posted a pretty direct response on Dell's Facebook page and Twitter feed but no response because they just dont care.

Thanks a lot. You are right. I have installed the A06 version and the flickering is now gone. Much relieved. I do not understand why don't they just install and check it before rolling out an update for something like bios, let alone the quality testing.

Just created an account to tell that with updated BIOS I got the same issue. 😞

This xps 9550 4k release had (has?) many problems since its release, looks like I won't buy blindly any high-end Dell notebook anytime soon. 😞

I have had this same issue and needed to revert also to the previous BIOS version... It's a shame.

I installed this Bios update only to be faced with an unusable flickering screen, I also had to roll back to previous version and now need to live with a daily reminder I have an update available..............

Still have the screen flicker on mine, on every brightness level, its not quite as bad on full but then the fan stays on permanently. Nothing feels hot, set to passive. It seems its just one thing after another with these things. So disappointed with this model, I had to go and buy another laptop just so I can carry on working whilst this waste of money goes back for repair. Last Dell I will ever buy!! Such a shame as it had the potential to be so good, everything is there, it just doesn't work.
