Hi guys, my dell v14t-5470-a20 is not working properly, I use two screens for work. Without changing or installing new programs, in recent days it has problems in the appearance of random pixels, and also turning off the screen when there is exchange of low-use programs of RAM.
I realize that when I leave in the "balanced mode" it does not give these problems, but does not play videos, for example on youtube it appears with flaws, scratches and black image, but the audio works perfectly.
When I change to "maximum performance" it blinks the screen too much, pixels appear colored throughout the work area and hangs constantly.
When I disable the "Intel HD Graphics" driver it obviously leaves the second monitor offline, but the problem disappears.
Same error on charging and the batery.
I have already performed the Dell standard LCD test, when I start "D + Power" and the colors appear correctly without errors, I reinstalled Windows 10 a few minutes ago, I updated all the notebook drivers and the problem remained.
Please help me.
I done all those steps again today, same error.
When I disable the Intel HD Graphics, the other graphic video works ok (Nvidia Gforce 740m).
I made one video to send to you, I sorry for my poor english on then.
I attached the forms you asked for.
These pixels and the black screens (and the time lost on it), its making my job impossible.
Thank you for the help.
