My screen became reversed from left to right after installing windows

Link99 · 15 Nov 2016

Hi everyone ,,
I have a strange problem after installing windows 10 that is my Laptop screen suddenly became reversed, when I turn on my laptop it shows my the company logo (acer) in reversed way like (reca) & even windows 10 logo is reversed when it appears at windows start !
the screen remain reversed after I login to my desktop and everything is also reversed .

( I am not saying that my screen orientation is reversed vertically or horizontally )

I have to switch on and off my laptop several times & cut the electricity and re-plug it again until I get the correct start screen and the correct windows display .

My battery is dead so I only use the wall charger to turn on my laptop .
My laptop is : Acer Aspire 5742 Z

* Note: I installed windows 7 again but that didn't solve the problem .

I will link some pictures that I took for my laptop screen that shows the problem ..

Since it happens at the Acer logo before windows even starts up, I would be looking in bios/UEFI.

Yea it happens before windows OS even starts !!

What can the bios problem be ?
& what should I do to fix this DISASTER ?

Try pressing Up/Down arrow keys while holding down Ctrl+Alt buttons.

I tried that but it doesn't fix the problem, it just change the screen orientation vertically or horizontally
the screen is in correct position when I start my laptop but just it appears like flipped 180 Degree from left to right as in pictures I uploaded

Is it under warranty? As it happens before Windows even starts (so that is nothing to do with it) it may be inverter cable, screen or motherboard...

The display can be flipped in Display Settings. With it happing before Windows loads I would suspect that the laptop is the problem. It may be a bios setting but I never saw a setting on any of my computers that would reverse the screen.

No it is not under warranty , its been about 3 years now since I got it .

My Bios type is Legacy not UEFI .. is that helping in anything ?

Could the problem be from my wall charger ? maybe it reverses the current or something ?

It's got to be a hardware fault. As far as I know there is no BIOS setting that will do this. If the power pack polarity was reversed one of two things would happen, nothing (PC would not power up), or the magic blue smoke would be released (PC would never power up again). I'm finding it hard to believe this could actually happen? I'm not doubting your problem is real, it's just very very unusual. I'm an electronic technician by trade and have never ever heard of something even remotely like this happening. I can't imagine how or why it would happen? If it was doing it in windows I'd be wondering if somebody pranked you or hacked your system. Happening right from boot up means its a hardware issue.

Indeed , I've looked over many issues related to windows display but never seen anything like what happening with me !

I was thinking that it might be either the Graphics card ( which is built-in ), it could be because overheat as in the last month I used to work on After Effects for some projects and I noticed there is some overheating during rendering process but my laptop was working perfectly .

Or
Maybe that because I use an external USB for Ready Boost in order to improve my RAM performance & maybe it caused some problem in the motherboard current ?.

I am thinking that it might be solved if I used an external Graphics card ???

Can this be a solution ?
