[Q] Black and white display

Is there any mean to turn display black and white like for S5 supersaving?

replace touch sreen only(xopo zp980)

I will try to explain again. If I look directly on the LCD screen then I only see a white screen. But if I look at the LCD screen via the touch screen (that is - I put the LCD off the touch screen) then I do see a display and not just a white screen. Between touch screen to the LCD screen was a bit liquid I had not known what it is and cleaned it. The problem is that right now even though I put on the touch screen the LCD and see display, the display is very weak. Why only when I look at the LCD via the touch screen I see display? Why when I look at it (on the LCD) directly I do not see a display only a white screen? Why after I separated the LCD and touch screen and then put them back together the display is weak?

how to turn off pixel lines

Hello
I have a dead line of pixels on my screen and i want to turn off the screen on that line(it is constantly white due to dmg to the OLED)
i tried with adb (overscan command) but that only moves them up and the area is grey
i was wondering if there is a way to completely turn off 10 rows of my screen so they stay permanently black

This is a feature of the amoled screen. All black pixels are actually off. Though if you don't want it, there is a way to disable it:
Settings>Advanced>Display>Ambient Display then switch it off

Problem after display change - Ulefone Armor 3T

Hey,
I got problem: after changing broken display, new on has some issues: i can see very small blinking horizontal stripes (darker and brighter, so they are visible mostly on colors other than black/white) and they are moving, like when you record screen with different refresh rate.
Also sometimes there is problem: when I turn on screen, after few seconds all colors change to bright and contrast is extremally high (like with using some bad picture filter), or very rarely i have vertical stripes, which become more visible, all screen becomes brighter and there is no response when I touch screen. This two problems dissapear, when I turn off and on screen again. (but I still can see delicate horizontal stripes - these are all the time)
Is it problem with software, or hardware?
If hardware, it is because broken/poor quality screen, or there is some issue (damage? dirt?) on the connection between screen and mainboard, on socket or band?
