My laptop screen displays on reverse direction

HP Pavilion DV6-2121er
OS: Windows 7 Home Basic
My laptop screen displays texts and symbols on reverse direction. For example, on the desktop "My computer" - as "retupmoc yM".
I did reinstall my OS, but it didn't help me.
What problem may be? Please, help me!

I have the same problem. A more accurate description would be that the display is mirrored...
If I view the reflection of my display in a mirror everything appears normal.
If I view my display directly everything is reversed horizontally pixel by pixel (i.e.. mirrored).
At no point during the boot process is the display correct. As soon as the BIOS posts the screen is messed up so this issue has nothing to do with the display driver as it's not even loaded yet.
My problem is actually slightly worse. My display is mirrored and then shifted to the right half a screen length with pixels beyond the right edge of the screen getting wrapped around to the left side of the screen. You can get a sense of the problem by doing or imagining the following scenerio:
1) Take a screen shot of your desktop.
2) Open the screen shot in photoshop and mirror it (not the same as rotating or flipping)
3) Print the screen shot and tape the left edge of the paper to the right edge forming a tube
4) Make the tube flat again by cutting it down what used to be the middle of the image.
Please help HP

External monitor works only works when laptop screen displays

Hi there, I just connected a different (newer, but not brand new) external monitor to my T61. When I toggle screens (fn-f7) the external display gets no signal in the 'external display only' position, but displays beautifully in the 'both' position. This never happened with my old monitor. I would like to use the external display and not have the laptop screen display. Any ideas? Many thanks, Ellen

Try this:
After connecting external monitor, press win key+p and thrn choose projector only.
Have a nice day

How can i get my laptop screen to display on a second monitor after closing the laptop

I have a 13" MacPro, love it, but its display is a little small for how far away i sit at my desk. I have a second 21" monitor that i would like to use for this purpose, but whenever i close the laptop screen it shuts down the signal for the second screen as well. Is there a setting that i am missing to be able to close the laptop and still use my monitor?

Hi AmandaBenton,
The article below will explain how to use an external display with your Macbook Pro.
The "Mirror Displays" option will show whatever you are seeing on your Macbook Pro on your TV screen.

Make sure your additional display is properly connected and powered on.
From the Apple () menu, choose System Preferences.
From the View menu, choose Displays.
Click the Arrangement tab.
Enable (check) "Mirror Displays" in the bottom-left corner.
I hope this information helps ....
Have a great day!

Hello chrispyw,
If your content is still being displayed incorrectly, I would check the resolution setting for the built in display with this article:
OS X Yosemite: Adjust your display’s resolution
If it keeps happening whenever you use AirPlay then I would use this section of the following article to reset the display system:
Apple computers: Troubleshooting issues with video on internal or external displays
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.

Sterling

Is it possible to loop a Keynote presentation on an external display while working in another program (say numbers) on my laptop screen?

I have a 2012 MacBook Air.
What I would like to be able to do is plug into an external display and project a looping Keynote presentation on the external display. The problem is when I play the Keynote presentation, my laptop screen goes black. Is it possible to play/loop a Keynote presentation on an external display while working in a different program (Pages, Numbers, etc) on my laptop screen?
Thank you!

Deactivate laptop screen with external display attached

Hi guys,
Once upon a time when you connected a powersource, peripherals and external monitor to your MacBook (Pro/Air) you could then open the laptop to allow for better cooling (useful) without activating the laptop's built-in display thus staying in single-screen mode.
However, since Lion you can't. Whichever way you try, fly, walk on your hands or smash your head into a wall Lion will always always activate the laptop's display when you open it up.
Anyone got a Clu how to get the old behaviour back?

1. Potential solution: Apple wants your forum feedback
Please see a post in the following thread and reply to it as you wish. Apple has now reportedly requested that we provide evidence in support of our desire to have the "open lid with screen off" option reinstated (eg significance of operating temperature differences, reduction in wifi reception, etc). They may then address our concerns with a Lion update.
https://discussions.apple.com/thread/3190417?start=60&tstart=0
2. The madness of magnets
This is getting very worrying. It's madness that Apple owners feel obliged to experiment with passing magnets over the top of their premium-priced computers and sticking them on here, there and everywhere in the hope of finding short-term workarounds. The sooner this problem is fixed at source (ie within Lion), the better.

Dual Display - Laptop screen won't wake up 50%+ of the time

My laptop is connected to an external monitor, with the monitor set as the primary display.
I put the laptop to sleep by closing the lid.
Often, when I open the lid the laptop screen will not turn on. Just the monitor, and then it acts as if it is a single display. The only way I've figured out how to fix this is to completely shut down the laptop and boot back up.
This started suddenly last month, right after changing jobs. The new job had an unknown amount of software installed (including MS Entourage) and the entire system encrypted by the new company's IT department. I don't know if these are related, but the coincidence is hard to ignore.
I also will occasionally not be able to fully wake the computer. I'll get a black screen and a mouse cursor but never get the log in prompt to bring it out of screen saver mode. This problem sometimes occurs with the above issue, but often they are separate. Though this also just started. (I suspect this second issue could just be performance problems with new software bogging down the system over several days). Although the same solution is to shut down the system. It's just that in this case, the only way to shut down is to force it with the power button.

I have a similar problem that just started recently. I've been using a dual monitor (Wacom Cintiq) since last Novemeber, and now at random times when I attempt to wake up the computer I get a black screen on both monitors. I know the computer is on because of the system beeps I generate while pressing the keys. The monitor just won't come on. Normally I thought the power light below the latch opening would cycle up and down, while asleep, but when this problem happens it is just on. When the lid is opened the light fades out. Computer is running, just no screen. The last time this happened I had to power it down. I've tried disconnecting the Wacom Cintiq monitor, the external keyboard and the Wacom tablet. No Luck.

W520 wont display 2 external monitors and laptop screen

Hi everyone.
I have previously had 2 external monitors working as well as my W520's screen, so 3 screens in total. A few days ago Windows 7 crashed with a BSOD and now I can only connect 2 screens at once.
Everyhting seems to be connected correctly as far as i can tell
This is the error I now get when trying to activate the 3rd screen.
Is there another driver I need to install to reenable the laptop monitor to work along witht the two external screens?
Any help is appreciated.
Like the song says... 'you dont know what you've got till its gone'.
Thanks
shane

Why isn't the second Acer external monitor (2 of 2) "checked" as well?
Don't you want all three screens in use??
How DID you have your monitors connected before the BSOD problem caused your current situation? Do you have the two Acer monitors daisy-chained via DP from the DP connector out of the K1000M on the laptop? And you were also using the laptop screen as the third? If so, I'd think that all three boxes would need to be checked in nVidia Control Panel.

Random laptop screen Black out / Turn off .

Hi,
first of all my laptop is : HP Pavilion dv6-6160se Entertainment Notebook
to the problem now
A few days ago my laptops screen started out of a sudden shutting down/turning black( no lights at all ). This was happening while using the laptop at random. The screen had no lights, and if i use a flashlight on it there is nothing. like its turned off completelly.
Before this happens. Ths behavior varies. Sometimes it flickers from my desktop to a black screen then back on and some times not. Most of the times screen changed to a radom color (green mostly) then becomes black/shuts down.
NOTE: The laptop keeps runing, i can hear the videos playing so it probably isnt a gpu chip or gpu issue , music and games.
I searched the web for all kind of reasons that this could happen and tried some of the fixes .
Here are everything i tried and all or the details i could accumulate in past coupe of days:
1. If the screen flickers , blacks out and then turns back on i get a message that gpu drivers have stopped working and recovered ( on both amd and intel ).
2. If the screen blacks out, on rare ocasions if you close the laptop lid and let the laptop go to sleep , when waking up screen works again ( noticable due to screen moving)
3. I tried installing 4 different drivers all with clear install. ( didn't work)
4. I tried to to recover system with restore point. ( didn't work)
5. I tried to lower the screen brightness. ( didn't work)
6. tried this trick:
Turn off laptop
Remove battery
Hold the power buttong for 30-45 seconds
Plug-in the charger ( dont put the battery in )
Turn on laptop and see if it works.
Very Noticable details:
7. Since on of the rare fixes requires to move the lid i tried shaking the screen a bit or pushing it slightly to different directions. This actually does the trick and turns the screen back on ( i am right now typing this after using this "trick"
So, with this one as a hint there are a couple of stuff i have in mind but i am not sure and need help since i am not a technician.
a) There is a loose LCD cable and when i type a little vibration moves it and ends up in a black screen.
b) I read that if you use a flashlight and you cant see your desktop it means its a bad inverter.
c) Can the inverter have a lose cabe instead of the lcd ?
That's all the feedback i could give you that i can recall now.
Currecntly the screen looks ok ( maybe its the certain angle it has after i moved it so i would aprecciate a fast reply before it goes black again
EDIT: Tried to play a game for a few mins and i got the black screen again. Closed the lid so the laptop goes in sleep mode then opened it and it worked. Just for the records.
EDIT#2: Just tried to play a game again. got the blackscreen, shaked the screen a bit and it worked but for the 1st time i get the message " Application has been blocked from accessing graphics hardware" , Can it be that its the GPU after all or maybe drivers?
EDIT#3: Tried to play a game again and it seem to trigger the issue . ( i am currently running the laptop with only the intel drivers installed)
thanks in advance
Sincerely,
Ntas
P.S. Please feel free to ask me any question if you need more information, i am not a laptop expert but i know more than the average person

Hi @Ntas
I have read through your post and it seems there are a couple of possibilities, and I noted that you have already tried several of the things I would normally suggest.
I will however post some of those links anyway for you to review, it is always possible there may be something in one of them that may have been missed or may inspire an idea of the cause. Since you mentioned that sometimes just moving the screen will cause the problem or make it disappear, that does seem like either a loose connection or maybe something like pressure on a part of the display causing the issue. Of course that last part may just mean the display is on its last legs, but hopefully not.
First I will give you a link to the service manual, to help you check the connections. Just be careful to read the sections on precautions, to protect yourself and to prevent any other damage.This manual is also useful in that it lists all the compatible parts, so if the display is defective you could use this guide to help order a compatible replacement if you choose to do so.

Start up Screen displays HP logo, then is blank.

Basically what is in the subject. When I start my laptop the screen shows the HP logo, then when it should go to the log in screen it is blank and blacked out. All other keyboard lights work and I can hear the hard drive. I've tried restarting and doing a hard reset. Am I doing something wrong? Hope someone can help.

Laptop screen remains black (off) when I turn on the computer

Hello,
Today I came home and turned on my laptop as usual except this time the screen remained black. I can hear the fan running and then the usual windows chime at start up, but nothing to view. The HP logo at the back still lights up though. Just the actual screen remains completely black like it is off. I tried connecting it to my tv via HDMI and to an external monitor but there's no signal. I also tried doing a hard reset which I read about here but that did nothing. I feel as though it's just the monitor won't turn on but everything else might be fine.

G72-B61NR Laptop screen black;Num & Caps locks blinks; Hard Drive works fine

Hello everyone! I would like to get a solution to a problem I've been having with my laptop; if no solution, then a reason for my problem would be great. My laptop has recently stopped booting up correctly. Basically the screen is black and will not turn on. The NUM LOCK and CAPS LOCK LED lights flash a number of times before the computer shuts down. When I turn on the computer I can hear the fan and the hard drive running but no screen. I have been able to take out the hard drive from the laptop in hopes of salvaging important documents and I was able to do so by connecting it to a desktop. Is there anyway to fix my screen and save my laptop? Thank you in advance for any help.

Hello soTERRAble, welcome to the HP Forums.
I see that you have a blank display with your notebook. I will try to help you with this.
From what you describe this could be indicating that something in the notebook is not working correctly, right now I wouldn't be able to tell you what but can provide you two documents that might be able to identify what.
Computer Does Not Start and the LEDs Blink or the Computer Beeps - this document may be able to assist you with the flashing LEDs your getting when trying to start the notebook. Watch to see if you can identify an error pattern. If you can compare it to the table in that document. This will provide an idea to what may be failing.
