Broken pixels on laptop screen.

September 6, 2011 at 15:54:32
Specs: Windows 7
I own a Lenovo Y550P operating with windows 7 and it is displaying broken pixels on the monitor. They are random and disappear at times. When I plug in an additional monitor the problem translates to the other screen even it is on Extend, Duplicate or Projector settings. Does anyone understand this problem? Thanks for the help

I was going to say a bad monitor connection in the laptop bezel until you mentioned the external monitor. Try updating your video card driver to the latest version from the manufacturer. Right-click on "Computer" (either on the desktop or in the windows menu) and click on manage. When the management console comes up, click on "Device Manager", expand "Display Adapters" and note your video card make and model. Go to the manufacturers site, and find the latest driver. Download, install, restart, and see if the problem is still there.

Thank You, jowah. Unfortunately, When I searched for NVIDIA GT 240M on their website an update for the 280 model was the only result. I tried to use it anyways but the NVIDIA instal manager said the update was not compatible. I appreciate the suggestion

At first it wouldnt allow me to install that update, but I guess third times the charm?! I installed, restarted and the problem is getting worse. I am noticing that pixels are displaying colors from somewhere else on the screen.

Your symptoms probably cannot be caused by software problems.

Problems with the built in display on a laptop are common after the laptop has been used a lot, or at any time if the laptop has been dropped or has had liquid spilled on it, but if the symptoms happen even on an external monitor while booting the computer BEFORE Windows loads, or when you go into the bios Setup, they can't be caused by any software on the hard drive - your video adapter is probably dying, and in most cases it's built into the mboard on a laptop - you probably must replace the mboard.

I dont know if this makes a difference either but I have noticed that if I move a window or move my mouse it agitates the display.It will return to a stagnate state of suck once i cease.

If the display and the external monitor show the same the problem is hardware and the problem is either in the frame buffer or the dac.
