Windows 10: My screen became reversed from left to right after installing windows
Please accept my unreserved apologies for suggesting that your thread was a hoax. I see your most recent image proves that keyboard and external monitor are normal compared to the laptop screen.
Since you can reverse the situation with certain repeated keyboard presses, is it possible that the keyboard is at fault, perhaps due to foreign bodies under the keys or some unknown object (above or below the keyboard module) causing the keys to activate? For instance, insect larvae heading to pupate in a dark spot can wriggle beneath the membranes that hold the key contacts apart, and momentarily operate them. After all, the original apocryphal computer "bug" (Grace Murray Hopper recorded it on Sept. 9 1947) was just that, a bug!
Retired from the grind
Pull the battery pack and pull the CR battery out, which should be where the hard drive is.
-Fafhrd- its ok .. & I totally removed the keyboard but it still the same issue . I even unplugged every cable connected to motherboard except the power key cable !
I checked the screen cable .. un-plugged , cleaned it and re-plugged it again many times but nothing changed ...
Here is a video so you guys can understand what is going on with me ... http://e.top4top.net/m_3237qy4u1.mp4
Ok I will try with the CR battery , ,
Ok, after pulling battery back and pulling CR battery out .... at the first boot the display was correct . But after restart the display got reversed again !
then I pulled out the battery and left the CR battery in & with the first boot the view was correct .. but after I made restart it was reversed ...
@Link99, I'm afraid your problem is more serious than a simple mirror-reversal of the screen. I've looked closely at your photo of the two screens. At the small scale there is a lot more going on. Individual vertical strips (probably 4 pixels wide) are NOT mirrored. Within each strip the pixels are displayed in the right order. It is the order of these vertical strips that has been reversed. You can see this clearly in these two snips from your photo. The first is your monitor, the second is the laptop's screen. Note that part of the curve of the capital G is clearly the correct way round on the laptop.
This suggests to me that a hardware fault is the root cause. The address lines that index the horizontal pixel locations are not working correctly. This also suggests that the fault is not in display adapter, some small comfort there. Rather it is somewhere between that and the pixels on the screen. It is possible that an incorrectly seated cable connecting the two could be the problem, but my diagnosis is that it's more likely to be a hardware fault in the screen itself. You may have to replace your screen, I'm afraid.
@Link99 As I understand it you say you've re-seated the flat cable that connects to the m/board. There is another connector you could try. It's on the back of the screen itself. You'll need to dismantle the screen itself to get to it.
Warning: there are high voltages here for the backlight! disconnect the battery and power cord before proceeding!
Dismantling instructions here:
...On the back of the screen, you'll see a thick cable attached to a gold connector and, held in place using strips of tape or adhesive. Disconnect this cable...
By "totally removed the keyboard" did you mean disconnected the built-in keyboard and used a USB keyboard in place of it?
I hadn't suggested that it was a cable or connector problem in this case, but there may be some physical problem with some of the keys on the laptop keyboard - which give the signal on booting to the display system to bring a mirror image to the screen, working on Bro's suggestion that it was kicking into some projector display mode - Particularly since you stated that you could could correct the display using the Ctrl Alt Arrow keypress.
Using an external keyboard with the build in keyboard disconnected - what happens?
Yea first I disconnected the keyboard but I didn't insert a USB keyboard ..
but when I insert a USB keyboard it is still the same problem !
- Bree -
Oh my god !!! But what could cause such a damage ?!!
Ok I will check the cable in the back of the screen & I really hope it solve the issue.
Hi, I keep getting a black screen with cursor appear on my laptop after I leave it alone for a while (not being used). I have read many forums with similar problems but after login or at boot, for me it just happens randomly when im not using it. I...
When using applications, I have always relied on Windows remembering their exact position from session to session, and on Windows 7 that was no problem. On Win 10, however, there is a problem with some of the app windows that I want to leave flush...

I just updated my win7 to win10, despite several negligible issues, so far I'm rather content about it.
HOWEVER there is one little, yet major problem I encounter and have no idea how to deal with; mentioned in the thread title.
Basically up is down and left is right
I could not find the settings in the mouse control config
