Last week, my laptop display unexpectedly decided to go haywire while it was switching graphic cards (going from ATI Radeon to Intel GMA). Now the image is displayed "right-to-left" instead of the normal "left-to-right". Some of you might already be thinking that it's just the screen inversion/rotation of the display driver, but NO, it's definitely a hardware problem as this behavior starts as soon as the computer boots with the BIOS screen and I have tried every setting I could think of.
Conversely, the display is fine with an external screen, both on VGA and HDMI outputs.
I have included two photos so that you can understand what the problem is about:
Laptop display: image is inverted + every other vertical line is swapped
External screen: image is normal
So now, since the laptop is out of warranty (but just 1.4yo and always handled with care) and I don't have the money to buy a new one (+ I think it would be a waste just for a display problem), I was thinking of simply getting a replacement screen (no problem installing that).
However, since I have not figured out exactly the root cause of the failure/current behavior, I also can't rule out that the problem might lie somewhere else. Thus I would like to know your view on the matter:
- Has anyone ever had the same problem?
- Do you think it's safe to assume that it's only a display problem since the VGA and HDMI outputs work fine?
Information about the computer
More informations about the computer if that can be of any help:

New information about screen (+datasheet)
I have tried to disassemble the screen (hoping it would be something easily resolved like a loose cable connection). This attempt was unsuccessful for solving my problem, but allowed me to note down the exact screen model:
- Manufacturer: AU Optronics (AUO)
- Model: B140XW03 V.0
- Version: H/W:0A F/W:1
And Google helped me find the relevant datasheet. However my limited knowledge on the subject did not allow me to get much out of this document for solving the issue: I hope others can find it more helpful...
