I bought a new Dell Inspiron 15 7000 - 7559 core i7 with touch display about a 4 days ago. I've noticed the screen flickers on low brightness level. (below 30%).
If you have any solution for this please let me know.
Updating the BIOS firmware, along with the chipset and video drivers should ideally fix the issue. Please visit our support site and enter the service tag. Then under drivers and downloads, select the right operating system that you have and it should show the drivers available.
Yes my screen is UHD (4K Touch) display.
that issue in hardware side or software side ?
i am waiting for your reply.
Thanks for the update.
i updated but brightness flickering still there. its flickering only between 0% to 30% brightness level. above 30% brightness level i can't notice brightness flickering. i have no idea what to do for this i love this laptop. is this a hardware fault in LCD Back light ?. i bought this laptop last Saturday. from 1st day this is happening. if you have any solutions for this tell me. i try & let you know.
Thank you for sharing the file. There doesn't seem to be any issue with the hardware of the system. Please check if the screen flickers or if you can replicate the issue while in the BIOS or the diagnostics screen.
I have the same problem 7559 4k screen UHD and it flickers from 0 to 30% I have the latest bios and drivers. going to the bios and lowering the resolution does not create the problem. I think its more to do with when whites are displayed but you must know better. The update tool you gave here fixed the problem little bit but not gone for sure. kindly ash the uhd manufacture LG(I suppose) to give another firmware fix. thanks
