Asus Laptop LCD Help
Im really confused as to what am i to do here since this is the first time that i have encountered this.
The image above is a shot taken from my laptop. Notice the bottom showing a small line of the top part of a browser. Apparently this happened just recently. About 2cm to 4cm of the top most part of the screen shows up at the bottom. Also this is followed by occasional shaking of the image displayed in my LCD.
Now i'm really confused as to what cause this problem. I haven't been taking my laptop with me for a few months now and i have not played any games on it and this happens. Does anyone know what problem this is? Not that i'm relatively new to laptop problems but this is the first instance that i had something like this.
Again to note:
- Laptop Model is : ASUS X83VB-X2 which i bought from Best Buy at Puerto Rico.
- The top part of what is displayed in the LCD is displayed at the bottom with aroujnd 2-4cm or so in height.
- LCD now has a green light above which is almost similar to the one at the bottom.
- tested the video out to my desktop's lcd and it shows no problems unlike the lcd in my laptop.
- Is accompanied by some shaking. From slight shaking to really shaking image display.
- i've only had this laptop for around 6 months or less so im sure it's under the warranty but is ASUS covering a GLOBAL WARRANTY and also i still have the receipt of it but it's faded to the point that it's barely readable.
PS: I reside in the Philippines (aka Clovisland)
Is this an LCD problem or what? Hope i could get some ideas on what this is before i send this out to a service center.
EDIT 1:
I just discovered that ASUS does not cover Worldwide warranty. If your country does not have the model out in the market then warranty does not cover it. In my case, this model never came to the Philippines.

Eerrr..... that's the first time I have seen this behaviour and I even got paid to repair PowerBooks once (a bit unofficial, but I did go though quite a lot anyway). Usually a broken display cable (going from main board to monitor internally) is seen as a region of dead pixels or a completely dead screen. It shouldn't shift the pixels like this.
I wonder if this is a hardware or software problem because I can't think of anything in the hardware, which can result in this (besides broken video chip).
My best advice is to back up everything and reformat the computer to see if it persists on a clean install. If it happens on a clean install, then you should push for a warranty repair. I don't know about Puerto Rico, but here if you have a near-non readable receipt, then they look up the serial in the database to tell the age.
A note about receipts. Do take a copy of it for safe keeping. Some shops decides to pay only half for the paper it's printed on and it's known to fade the ink over time. A copy based on laser printer technology will burn the text into the paper and that will not fade. Officially the shops use such paper to cut down their own costs, but I suspect that killing documentation for warranty is a even better financial goal for them. The text is readable in like 3 months.
I just thought of something else to try: switch resolution. If it's a defect in the LCD itself it should be unaffected by resolution. If the LCD just draws the pixels it's informed about, then it should change size as you change resolution.
Another thing would be to do a dead pixel test. There are apps on the internet, which can make your screen all blue/green/red/white/black to search for dead pixels. Such an app could tell you if the software can control that region of the screen. A fullscreen DVD movie or similar would do that test as well.
You can also download a linux live CD and boot from that one. If it's a software problem booting from a CD would certainly avoid it. Booting from the Windows install CD might work too, but that one is likely in 640x480 or something. Better test linux at full resolution.
None of those ideas would get rid of the problem, but finding the cause is a step in the right direction. I hope for you that it's a software problem.
even this is the first time i've seen such a problem. i'm a member of a tech site from about 4 years and haven't come across this problem till now.
you can try one thing - remove the display drivers and get them reinstalled. if the problem persists then it is most probably a hardware problem. RMA it if its under warranty.
you might want to check resolution settings too
do a driver update first
Try changing the resolution if that doesn't work uninstall geforce drivers and reinstall. If that still doesn't work back up everything and do reformat of everything. Last two options if the problem is still there. If you got the money and time go directly to asus and if not go to gilmore.^^,

I'm pretty much sure it's a hardware problem (in this case the LCD or the cable is a bit lose)
- or it could be heavy interference, but I doubt it.
I'm somewhat sure that a lose display cable would result in pixels failing to be displayed. Technically (based on how the data is transmitted) the pixels can be drawn at incorrect locations, but then nothing should be drawn where the pixels were supposed to be drawn.
I have a computer here with a broken display cable. The connection is lost in one of the connectors. The result on the screen is one missing colour in every 3rd vertical line on the top half of the monitor.
I don't think it can be interference. Interference has a certain amount of randomness and I read this as a static problem. Interference should make pixel draw incorrectly, and would likely look somewhat like static on an analogue TV. Well it would for each colour or something, which would make it a quite interesting view ^^
Does this system use shared ram for video? You might have some ram going bad if so. I've seen things like this over the years; could be video card, cable, or bad LCD (rarely)
I'd start with the driver, in any event.
Lots of rars
